 INSTALLATION
(1) Always wear protec ve clothing, face shield, safety glasses and gloves when working on or near
your metering pump. Addi onal precau ons should be taken depending on the solu on being
pumped.
(2) Pump is to be protected from sun and rain. If outdoor installa on is unavoidable, provide a
canopy over the pump. Pump should be accessible for rou ne maintenance and should not be
subjected to ambient temperature above 50° C.
(3) Flooded suc on -: The pump is mounted at the base level of the storage tank. This installa on is
most trouble free and is recommended for low flow output and high viscosity solu ons. Since
suc on tubing is filled with solu on, priming is accomplished quickly and chance of losing prime
is reduced.
(4) Suc on li -: Suc on li should be less than 1.5 meter for solu ons having a specific gravity of
water, for denser solu ons consult factory.
(5) The foot valve act as a check valve to keep the pump primed in suc on li applica ons.
(6) The valve is designed to submerge in the solu on tank or drum and must sit in a ver cal posi on
at the bo om. Posi on approximately 2 inches off the bo om if the tank or drum contains
sediment.
(7) Injec on valve prevents back flow from the main line. When installing the injec on valve, be
sure to posi on it in ver cal so that the valve enters from the bo om of the pipe line.
(8) Mount the pump on a tank/surface using moun ng bracket and nut-bolts provided.
(9) Tighten the nut-bolts properly.
(10) The discharge point marked with arrow on dosing head should be always faces upwards.
(11) The suc on nipple will be on the lower side with the suc on tubing being immersed completely
in the dosing liquid.
(12) A er cu ng an appropriate length of tubing, connect tubing to injec on valve and then back to
the discharge side of the pump head.
(13) Use the remaining tubing on the discharge side and connect the back injec on valve to the
injec on pipe into which dosing is to be done.
(14) Connect the nozzle on the pump to the injec on valve.
(15) Plug the pump.

ESSENTIAL SAFETY REQUIREMENT
Ÿ Install the pump in any shaded place away from direct sunlight.
Ÿ The pump can not be used fin sub-merged condi on.
Ÿ Before star ng work on the pump, the pump must be disconnected from the power supply. The system must
be pressure less.
Ÿ Make sure that any chemicals that are released from the pump or any damaged lines do not causes damages to
system parts.
Ÿ Before switching on the main supply, the tubing cap (both suc on and discharge valve assembly) should be
ghtened to dosing head properly so that the metering liquid can not spray out from the dosing head in
working condi on and put operator's in risk. The dosing medium/liquid is pressurized and can be harmful to
health and the environment.
Ÿ When working with chemicals, the accident pretension regula ons applicable at the installa on site should be
applied (e.g. wearing protec on clothing's). Observe the chemical manufacturer's safety data sheet and safety
instruc ons when handling chemicals.
Ÿ The dosing medium must be a liquid, Observe the freezing and boiling point of the dosing media. The
resistance of the parts which comes into contact with the dosing medium, such as the dosing head, PTFE ball
and washer, glass ball, 'O' ring, ball bush, pipe lines, ball seal and suc on filter assembly, NRV body etc. ,
depends on the medium, media temperature and opera ng pressure. Ensure that the parts come contact with
the dosing medium are resistance to the dosing medium under opera ng temperature and pressure, see the
data booklet.
Ÿ Ensure voltage is within range specified for the pump i.e., 230 ±10% V.
Ÿ Electrical connec on should be made between Live – Neutral and Not live-Ground.
Ÿ Avoid giving supply from the same line as heavy electrical equipment.
Ÿ Do not operate the pump with a damage/break diaphragm. Opera ng with damaged diaphragm can lead to
dosing liquid entering pump housing. In case of diaphragm breakage immediately separate the pump from the
power supply. Make sure the pump cannot be put back into the opera on by accident. In case of diaphragm
breakage use the following step to dismantle diaphragm (refer fig. of Edose Dosing Head overview):
1.Make the system pressure less.
2.Empty the dosing head before maintenance and flush it, if necessary.
3.Set the frequency knob to 0%.
4.Switch off mains supply.
5.Take suitable steps to ensure that the returning liquid is safely collected.
6.Dismantle the suc on and discharge tubing and check whether tubing is blocked, soiled or damaged, replace if
necessary.
7.Dismantle NRV body in suc on and discharge side.

PAGE 13
www.initiativeengineering.com
 8.Remove the ball bush and o ring from NRV body. Check their safety for wear and damage.
If necessary, replace them.
9.Unscrew the PCB housing and remove it.
10.Remove the spring fi ng washer and nut and PTFE washer.
11.Loosen the screws on dosing head and remove the screws.
12.Remove the diaphragm washer, plunger washer and diaphragm o ring from diaphragm-plunger assembly.
13.Dismantle the diaphragm-plunger assembly
14.Check the diaphragm. If necessary, replace it.
