SECTION I: SAFETY INFORMATION (TON CONTAINERS)
TAKE CARE WITH CHLORINE!
1. Valve protection covers must be on ton container valves before they are ever moved.
2. The ton container should be levelly placed on a pair of trunions.
3. Always place container so valves are in vertical alignment and use only the top valve (which is the gas
valve).
BOTTOM VALVE IS LIQUID—DO NOT USE.
4. For best operation and safety, the ton container and vacuum regulator should be protected from the ele-
ments and
direct sunlight.
5. NEVER apply heaters or heat lamps directly on a chlorine container.

IMPORTANT NOTE:
Whenever possible, the use of chlorine gas manifolds should be avoided. Because manifolds contain pres-
surized
chlorine gas, they pose an increased risk of a chlorine gas leak. When the system design necessitates the
use of
manifolds extreme care should be taken with regards to their installation, operation and maintenance.

SECTION II: DESIGN AND INSTALLATION NOTES

1. The “all vacuum” system means that system will shut off at the vacuum regulator inlet valve, should
the vacuum line be broken, if water is stopped for any reason, or if the vacuum regulator is physically
damaged.
2. Choosing a vacuum regulator feed capacity:
VACUUM REGULATOR SIZE SHOULD BE ON MAXIMUM POSSIBLE FLOW.
Imperial Units:
GPM x 0.012 x (PPM) Dosage = PPD
Gallons Per Minute Parts Per Million Pounds Per Day (Cl 2)

Example: 30,000 GPM x 0.012 x 3 PPM = 1080 PPD

In this example a 2000 PPD vacuum regulator would be adequate.

4
 Metric Units:
M3/Hr x (PPM) Dosage = Gr/Hr
Cubic Meters Per Hour Parts Per Million Grams Per Hour (Cl 2)
3. TOTAL BACK PRESSURE is the pressure in the pipeline to be chlorinated plus the friction losses in the
solution line between the ejector and the point of injection at the pipeline. Ejectors capable of operating
with back pressures up to 150 PSIG (10 bar) are available depending on the ejector model and capacity.
4. It is preferable that the ejector be located near the point of solution injection in order to eliminate the
need for solution lines. Friction losses in the solution line will increase the ejector back pressure.
Friction losses can be reduced by increasing the solution line internal diameter and limiting the number
of flow restrictions and turns. Also, be sure that the solution line material is resistant to the highly con-
centrated chlorine mixture. Avoid solution lines wherever possible.
5. Schedule 80 PVC pipe is recommended to carry the chlorine under vacuum from the vacuum regulator to
the ejector.

SECTION III: SYSTEM INSTALLATION

(I) INSTALLATION OF FLANGED EJECTOR (Refer to Figure 1A)
1. Installation of Ejectors:
a. The water inlet and outlet connections are 2" or 3" flanged, four bolt, 150 lb., Van Stone style in
Schedule 80 PVC.
b. The shorter end is the water inlet (nozzle side) and the longer end is the chlorinated solution
outlet.
c. Install both flanges carefully with new flange gaskets from Hydro Instruments.
2. Testing of ejector. (Note: The vacuum regulator should not be connected and the chlorine container
valves should remain closed.)
i. Piping hook up to ejector (Refer to Figure 1A):
a. Ejector should be installed down stream at a sufficient distance so that chlorinated water is
not re-circulated through the booster pump.
b. On the water inlet side to the ejector nozzle the following should be installed: a water inlet
valve,
Y-strainer, and a pressure gauge.
ii. Testing for sufficient pump pressure to operate ejector. Also checking that booster pump (if ap-
plicable) operating in the proper direction.
Note 1: Ejector must have some back pressure to prevent jetting. (Jetting causes loss of
vacuum)
Note 2: When injecting into a contact chamber a tee should be installed on the solution line with
a vacuum breaker to prevent siphoning.
a. If operating with city water pressure (no booster pump), open the water inlet valve to the

5
 ejector and feel for suction (with your hand) at the gas intake of the ejector.
b. If using a booster pump, open the water inlet valve to the ejector and the pressure gauge
should indicate a sufficient boost. (See ejector curves at the end of this manual.) If pump is
operating in proper direction there should be a strong vacuum at the gas intake of the ejector.
Feel for suction (with your hand) at the gas intake of the ejector.
c. If the ejector has tested satisfactorily continue on to the next step (Installation of Floor Cabi-
net and/or Vacuum Regulator).

(II) INSTALLATION OF FLOOR CABINET

1. Location: Select a location for installation of the floor cabinet where it will be protected from
unauthorized personnel. The location should be selected to permit easy access to both the front
and rear of the cabinet for operation and maintenance procedures. The cabinet is not suitable for
outdoor installation.
2. Connections: Schedule 80 PVC union connections are provided with all Hydro Instruments floor
cabinets for the vacuum inlet from the vacuum regulator and vacuum outlet to the ejector. The size
of the union is dependant on the capacity of the floor cabinet. Refer to Table 2 for connection sizing.
Threaded connections should be prepared with PTFE (Teflon) tape prior to assembly.
3. Wiring: For wiring installation consult the Series OV-110 or CV-230 operation and maintenance
manual.

(III) INSTALLATION OF VACUUM REGULATOR

1. Mounting: Install the vacuum regulator panel vertically on a wall in a location convenient to the

TABLE 2: Vacuum Line Piping

Capacity (Max) Piping Size
2,000 PPD (40 kg/hr) 1"
8,000 PPD (160 kg/hr) 1 1⁄2"

NOTE: Ensure threaded connections are clean and
prepared with adequate PTFE (Teflon) tape or other
suitable thread sealant. Do not over tighten PVC
threaded connections.
gas manifold piping. The drip leg must extend downward.
2. Manifolds: A 3⁄4" forged steel union is provided for connection to the gas manifolds. Ensure this
union is tightened evenly but not excessively after connections have been made.
3. Vacuum Connections: The size of the vacuum connection is determined by the capacity of the
vacuum regulator. Schedule 80 PVC piping is recommended for vacuum lines of 1,000 PPD (20 kg/
hr) or higher.
A threaded Schedule 80 PVC union is provided with the vacuum regulators in the appropriate size.
Connect vacuum outlet on vacuum regulator to either the remote meter panel bottom union, a gas
inlet union on the switchover module or the gas inlet on the floor cabinet (depending on the system
arrangement). See Figures 2 and 3 for details.

 4. Vent Tubing Connections: All Hydro vacuum regulators are equipped with a vent tubing connec-
tion for directing and venting chlorine gas to a safe location. Tubing is also provided.
Connect the appropriate tubing (provided) to the vent connection on the vacuum regulator vent
fitting. Run the vent tubing to a safe location (outside the building). Whenever possible, avoid low
spots in the vent tubing and direct the tubing down from the vacuum regulator to keep moisture from
accumulating or entering the vacuum regulator. Install an insect screen (provided) on the outside
end of the vent tubing.
5. Drip Leg Heater: Prior to startup of the system or prior to placing any new ton container on suc-
tion, the drip leg heater(s) must be powered for at least 15 minutes. This will ensure proper evapo-

ration of trapped chlorine liquid takes place. This heater must always be powered during operation.

(IV) SWITCHOVER MODULES AND REMOTE METERS (Refer to Figure 3)

1. Switchover modules: (Gas flow is from bottom/side to top from one side only at a time)
a. Connect the two lines from the vacuum regulators to the side unions.
b. Connect the single line out to the remote meter(s) to the top union.

8
 2. Remote Meters: (Gas flow is from bottom to top through the tube)
a. Connect the input line (from the vacuum regulator or switchover module) to the lower union.
b. Connect the output line (to the ejector) to the upper union.

Figure 4: Electronic changeover system. Pressure switches indicate when the pressure
falls in the supply containers in use indicating that they are nearly empty. Then the
controller closes the valve in the line for that set of containers and opens the other
valve. Before removing the empty containers, the container valves must be closed
and the valves opened to allow the full evacuation of the depleted manifold.

SECTION IV: CHLORINATION SYSTEM VACUUM TEST

1. Do Not open chlorine container valve until vacuum test is satisfactorily completed.
a. Vacuum Test
With the chlorine container(s) still closed, start the ejector booster pump and the meter tube float
should drop to the bottom within about ten seconds. If the float continues to bounce there is a
leak. At this time the rate valve on the remote meter should be open two or three turns. If a leak is
indicated, inspect all piping connections and gaskets.
b. Turn off water supply to ejector.
c. Wait 5 to 10 minutes with water supply off. The vacuum gauge should maintain the indicated
vacuum.
d. If the system is vacuum tight proceed to the next step.
e. Disconnect a union in the vacuum line to allow air to enter the system. Reconnect union.

SECTION V: START UP OF CHLORINATION

Material necessary: A small plastic squeeze bottle (provided), 1⁄3 full of household ammonia, for detecting
chlorine leaks. When ammonia fumes contact chlorine gas a visible white smoke-like
gas is produced. (Wipe up any splashed liquid ammonia.)
1. Open chlorine container valves 1⁄4 turn and close immediately.
2. Squeeze ammonia bottle (ammonia fumes, not liquid) at all pressurized areas. If no fumes appear the
seals are tight and it is OK to proceed to the next step. (NOTE: The fumes are best observed against a
dark background.)
3. Open chlorine container valve(s) 1 turn, leave open, and recheck for chlorine leaks. (1 turn open of
the container valve is all that’s required. In an emergency you can shut it off quickly and safely. The
wrench should always remain on the container valve while container valve is open.)
4. Turn remote meter rate valve knob to the right (clockwise) until shut (for startup). This will prevent the
float from “jumping” during startup.
5. Turn on water supply or booster pump to ejector and set rate valve to desired flow rate. Refer to page 23
for the proper float reading edge.
6. Rate valve is not a shut off valve: it is a flow rate control only. To shut off chlorine feed close the
chlorine container valves.
7. For automatic control valve start-up refer to the OV-110 or CV-230 O & M Manual.

9
SECTION VI: SHUT DOWN PROCEDURE
1. Close the chlorine container valves while the water supply to the ejector is still on.
2. Wait for the float to rest at bottom of meter tube.
3. Break vacuum by loosening a union (preferably nearest the vacuum regulator) in the vacuum line and
retighten. (Repeat at least 2 times for more complete removal of gas from the system.)
4. Shut down the water supply to the ejector.
This procedure of shut down must be followed before any connections to the manifold are opened.

SECTION VII: RATE VALVE OPERATION

PREVENTATIVE MAINTENANCE NOTE: Rate valves that are not exercised frequently may experience a
build up of
a white powdery substance which precipitates out of the chlorine gas. In order to avoid this build up, which
can cause the rate valve to become stuck in place, it is recommended that the rate valve be periodically ex-
ercised. See Appendix Section A-II for rate valve maintenance instructions.

MANUAL OPERATION OF SYSTEM

Two true union ball valves are used to isolate the automatic control valve for manual feed rate control when
maintenance or repair is necessary. These valves are accessible from the rear of the floor cabinet.

SECTION VIII: TROUBLESHOOTING

(I) PRESSURIZED LEAKS
1. Pressurized chlorine leaks are a safety hazard to life and equipment and should be corrected im-
mediately. When searching for this type of leak there are basic safety rules to follow.
a. Air breathing pack should be readily available and personnel should know how to use it properly.
b. Exhaust fan switch should be located near outside entrance with an additional alternate out-
side switch
appropriately located.
c. Chlorine valve wrenches should remain on the container valves whenever they are open.
d. Plastic squeeze bottle 1⁄3 full of household ammonia.
e. Buddy system used (two people capable of operating system).
2. If a leak is detected the following should be checked first:
a. The inlet section of the vacuum regulator.
i. Tighten the hex filter cap.
b. The chlorine gas manifold pipe system from vacuum regulators back to the ton containers.
c. Chlorine container valve packing.
i. Tighten the container valve with care, not excessively! Close the valve if problem persists

10
 and notify your chlorine supplier.
ii. If valve is the problem try to move container with a high degree of safety to an outside loca-
tion. (Never attempt to place container in water as this will only increase the leak and the
container may float to the surface.)
d. Chlorine leaking out the vent due to the inlet safety shut off valve having dirt or damage on the
valve seat.
i. Close the chlorine container valves.
ii. Wait until the metering float drops to zero on the flow tube.
iii. Turn off water supply to ejector.
iv. Now remove the vacuum regulator inlet valve assembly.
v. See Appendix Section A-I for inlet safety shut off valve servicing instructions.
vi. After servicing and remounting vacuum regulator with a new lead gasket, pull a vacuum
test before you turn on the chlorine container valves. See “Chlorination System Vacuum
Test” (Section IV).

(II) NO CHLORINE FEED

Possible causes:
1. No vacuum being produced by ejector.
a. Disconnect piping at the ejector intake and place your hand on it; you should feel a suction.
b. If you feel no suction (vacuum) check in this order:
i. Nozzle (See Appendix Section A-III): Turn off water supply and remove nozzle from
ejector.
(1) It may be clogged with a stone or other foreign matter. Flush out or run pipe cleaner
through only.
(2) If there is a build-up of rust, iron, or manganese, place the nozzle in a Muriatic acid
for five minutes and rinse with water. If you see any buildup inside, you may find it
necessary to clean
the nozzle on a preventative maintenance schedule.
ii. Inlet Water Supply.
iii. Reduced city water pressure.
iv. Y strainer requires cleaning.
v. Booster pump cavitating (lost its prime).
vi. Booster pump insufficient boost due to wear or single phasing due to loss of one leg of
power.
2. Chlorine flow blocked at vacuum regulator inlet assembly.

11
 a. The chlorine gas filter could be clogged.
3. Out of chlorine.
a. The scale would read 2000 lbs. (1000 kg) lighter than when container was new.
b. Meter tube float would be at zero.

(III) CHECK VALVE FAILURE (Water in flow tube and vacuum lines)
1. Cause – Ejector check valve failure. Possible causes of ejector check valve failure:
a. Objects or material preventing closure of ejector check valve.
b. Failure of ejector check valve o-ring.
c. Failure of ejector check valve diaphragm.
2. Corrective Action
a. Follow Appendix Section A-IV to repair ejector check valve.
b. Disassemble and dry vacuum regulator(s), remote meter(s), and switchover module.
c. Follow Section IV vacuum test procedure before resuming chlorination.

APPENDIX: REPAIR AND PREVENTATIVE MAINTENANCE

Hydro Instruments vacuum regulators require little service when operated according to instructions. The fol-
lowing are recommended maintenance instructions.
NOTE: All Hydro Instruments systems come with a three year limited warranty. Hydro Instruments does
repair and refurbish used units at the factory. The repaired and retested units are shipped within 48 hours of
arrival at the factory with a one year warranty.
Guidelines for Preventative Maintenance: See below for detailed instructions.
1. Service Rate Valves every 4 months. (See Section A-II)
2. Replace Rate Valve O-ring every 12 months. (See Section A-II)
3. Service Flow Meter every 12 months. (See Section A-II)
4. Service Ejector every 12 months. (See Sections A-III and A-IV)
5. Inspect and clean vacuum piping every 12-18 months. Replace as needed.
6. Thoroughly inspect and clean chlorine gas pressure manifold piping every 12 months. Replace any cor-
roded or damaged parts as needed.
CAUTION: Use all recommended precautions when using chemicals of any kind, including goggles,
gloves, face shields, etc.
After any of the listed repair procedures, it is necessary to go through the Start-Up (including vacu-
um test) again!

SECTION A-I: SERVICING THE VACUUM REGULATOR

1. Inlet Filter: The inlet filter consists of a Silver filter screen (VRH-133-000) located under the hexagonal
filter cap (VRH-229-000) in the inlet assembly. This cap is sealed to the inlet assembly by means of a
lead inlet gasket (GAH-LED-124).
a. Remove the filter cap and pull the inlet filter out of the assembly.

12
 b. Clean the screen by submerging and agitating in hot soapy water.
c. Dry the screen thoroughly with compressed air prior to reassembly.
d. The lead inlet gasket should be replaced whenever servicing or replacing the inlet filter Silver screen.
e. Tighten the filter cap to seal the lead gasket. Test carefully to ensure there is no leak before resuming
operation.
2. Venting Gas: Venting gas is caused by the inlet safety valve failing to completely isolate the pressurized
chlorine gas during stand-by operation. It is indicated by chlorine gas leaking from the end of the vent
tubing. This can occur in a switchover system to the unit not on suction or in a single-regulator layout
when the system is idle.
The inlet safety valve can leak because of debris or buildup on the stem or seat preventing the valve
from fully shutting or by damage to the stem or seat caused by passing debris. Maintaining gas filters is
the best way to prevent venting.
3. Servicing the Inlet Safety Valve: To repair a venting vacuum regulator, it is necessary to disassemble
the inlet capsule, clean the Valve Plug (VRH-141-000) and replace the inlet seat and adapter (VRH-
15082-000). O-rings should be replaced whenever maintenance is performed on the inlet capsule.
a. To service the inlet safety valve, remove the inlet assembly (VRH-1841-000) from the vacuum regula-
tor back-plate by unscrewing the four hex bolts (BTH-STA-139). This will expose the inlet capsule.
b. Once the inlet capsule has been removed, carefully disassemble by unscrewing the Valve Plug (VRH-
141-000) from the vent screw (VRH-182-000). This will require two flathead screwdrivers. Take care
when disassembling, as the inlet capsule is spring-loaded.
c. Replace the inlet seat and adapter (VRH-15082-000), o-rings and clean the inlet plug prior to reas-
sembly.
See drawing on page 15.

4. Inspection of the Inlet Assembly and Drip Leg: As with pressurized manifolds, it is necessary to peri-
odically inspect the drip leg and inlet assembly for corrosion and damage. Because these parts contain
pressurized chlorine gas, extreme care should be taken with regards to their maintenance.
The interior surfaces of the inlet assembly (VRH-1841-000) should be carefully inspected whenever
the inlet capsule is serviced. If wear or corrosion is found, this part should be replaced.
If a leak is found on the drip leg piping, the piping should be disassembled, cleaned and inspected. If
wear or corrosion is found, the damaged part should be replaced. Extreme care should be taken when
assembling threaded piping connections.
NOTE: After performing any maintenance on pressurized piping connections, a pressure test should be
conducted with air prior to reinstalling in the chlorine gas system.

SECTION A-II: REMOTE METER

NOTE: Carefully follow shutdown procedures before performing this repair.
1. Rate Valve
a. Fully unscrew and remove the rate valve from the meter assembly.
b. Inspect and clean the two Rate Valve O-Rings and replace them if necessary.
c. Clean out any visible debris or corrosion found in the meter or on the rate valve.
2. Meter Tube Assembly
a. Carefully remove the protective covers.
b. While carefully preventing the flow tube from falling, unscrew the meter inlet plug to allow the meter
tube to be removed.
NOTE: For the RMH-4000-CL2 the bottom water block must be removed to remove the meter tube.

13
 c. Inspect and clean the top and bottom o-rings or gaskets. Replace them if necessary.
d. Clean the tube, float and stops carefully before reassembly.

SECTION A-III: EJECTOR NOZZLE AND THROAT

NOTE: Carefully follow shutdown procedures before performing this repair.
1. Be sure to isolate the ejector on both intake and outlet sides to prevent leakage of water or gases.
2. Disconnect the vacuum intake connection.
3. Disassemble both the intake and outlet water connection flanges and remove it from the water pipeline.
4. Remove the flanges from the Ejector Body.
5. Unthread the nozzle and throat from the Ejector Body. Take care not to damage the threaded portion.
6. Inspect and clean the nozzle and throat interior. Soaking in Muriatic Acid is recommended if scale
build-up
is present. Replace them if necessary.

SECTION A-IV: EJECTOR CHECK VALVE

NOTE: Carefully follow shutdown procedures before performing this repair.
1. Remove the four bolts holding the two Check Valve Body parts together.
2. Lift the Check Valve Top Body away from the Check Valve Bottom Body.
3. The Check Valve O-Ring should be replaced. When installing a new Check Valve O-Ring, carefully en-
sure it is evenly seated in the groove. Lubricating the new O-Ring with Fluorolube is recommended.
4. Inspect the Check Valve Diaphragm for damage (holes, cracking, etc.). If necessary, unscrew the dia-
phragm nut and bolt, preferably using a Spanner wrench and tongue and groove pliers. Use care not to
snap the nut. The Check Valve Diaphragm should be replaced every 12 to 24 months.
5. Replace the spring only if it is damaged.
6. Replace any parts necessary and reassemble.

SECTION A-V: SWITCHOVER MODULE

NOTE: Carefully follow shutdown procedures before performing this repair.
1. Disconnect all three vacuum connections and remove the switchover module.
2. Unscrew the BTH-STA-125 screws that hold the Body Flanges to the Center Body.
3. Inspect and clean the DIH-116-000 Diaphragms. If any imperfections are found or if these have been in
place for 12 months or longer, they should be replaced.
4. Inspect and clean the OH-VIT-217 O-Rings. Replace if necessary.
5. Remove and clean out any debris or corrosion.
6. Manually check to ensure that the mechanism can be switched in both directions without excessive
force and without binding.
