Section 1
OVERVIEW
APPLICATION
The VAC HE-series (or GBX and DLX-series*) Dri-Lab provides a
working area of inert atmosphere nearly free of moisture, oxy-
gen, and if desired, nitrogen. Any material that is sensitive
to moisture, oxygen, or nitrogen may be worked with freely. The
Dri-Lab is designed for use of argon gas as the principal inert
gas, and also may use helium, nitrogen, or any combination of
these gases.

FUNCTIONAL DESCRIPTION
The HE-series Dri-Lab consists of an hermetically sealed glove
box, a side-mounted antechamber, and a full-view window (Figure
1-1). The glove box and antechamber share an entry/exit airlock
door, used for passing materials in and out without disturbing
the glove box atmosphere. All materials are passed in and out
of the glove box on a sliding tray (located on the bottom
of the antechamber). The IS-in. I.D. antechamber, with one
interior and one exterior door, permits large objects to be
passed into and out of the glove box.

Two 9-in. glove ports and butyl rubber gloves, mounted in the
full-view window, provide easy access to all areas of the glove
box. An assortment of gas, water, and electrical connections
are also provided in the rear of the glove box wall. (Refer to
Appendix A for Dri-Lab specifications.)

*For simplicity, this manual will address the HE- rather than
the GBX- and DLX-series Dri-Lab. Both models are essentially
the same. The HE-series has removable end panels and a skylight;
the DLX-series does not. The HE-series is available in aluminum
or stainless steel; the GBX- and DLX-series are available only
in stainless steel. GBX-series has removable end panel~ and no
skylight.

WARNING I
Do not use halogen leak detection equip-
ment for leak testing. Halogens are
harmful to certain materials used in the
construction of VAC equipment (i.e.,
copper and rubber). VAC will not assume
responsibility for systems tested by
methods other than defined in this
manual.

TEST ONE
VAC recommends using helium leak detection equipment. If no leak
detector ~s available, the follow~ng test procedures are recom-
mended (keep Dri-Lab and room temperature constant throughout
testing) :
A. Connect a source of gas to one of the connections in the
back of the Dri-Lab (see Figure 2-2).
B. Close antechamber outside door; close evacuation and refill
valves.
C. Open inside antechamber door.
D. Slowly pressurize Dri-Lab. The gloves will be forced out.
E. Stop pressurizing when gloves are almost horizontal. (Let
gloves break slightly from horizontal.)
F. Place a stool or chair with a ruler taped on its back to
within 1/4 in. of glove finger tip. Note reference point
and wait approximately 1 hr.
o If system leaks, gloves will fall more than 1/8 in.
Locate and seal leaks. Repeat test until gloves remain
steady for several hours.
a Relieve pressure on gloves after testing.
o Replace plugs removed for leak testing with teflon-
taped brass plugs (user supplied).

2-4 Ori-Lab-R2-9/99
 c____ _ _ _ Vacuu m/Atmospheres

TEST TWO

If a water manometer is available, connect it directly to Dri-

Lab via any fittings in back and use manometer as a pressure
indicator. (CAUTION: Box pressure should not exceed lO-in.
water column.)
a Set pressure to 4-in. of water column.
a If system leaks, pressure will fall more than liS-in.
Locate and seal leaks. Repeat test untill gloves
remain steady for several hours.
o Relieve pressure on gloves after testing.
o Replace plugs removed for leak testing with teflontaped
brass plugs (user supplied).

TEST THREE

If this glove box equipped with Pressure Control of any model.

Do the following:
A. Set the high side of Pressure Control unit to + 5
inches water column. And set the low pressure side
to + 1 inch water column.
B. By using the foot switch and depressing on the right
side of it the gas valve will energize and the pressure
will rise in the glove box.
C. Set the pressure at + 4 inches water column with all
gloves fully extended outside.
D. After the pressure stabilized, monitor it for any drop.
E. If the pressure drops at any rate then we have a leak.
If not then the system is ok.

NOTE: If the glove box has a Dri-Train or any accessories such

as: CS-40, Cold Well, or Mini AIC, make sure that the
pressure is equal in all the internal of the glove box
including all accessories. That means leave CS-40 door
open, Cold Well lid off, and AIC inside door open.

LEAK TESTING DRI-LAB WITHOUT DETECTOR

Leak in Gloves
Gloves are vulnerable to leaks, especially in the fingertips. To
check for leaks:
A. Stretch rubber to detect small holes.
B. Check for cracks near glove port.
C. Inflate glove, twist wrist, force into pail of water, and
look for source of bubbles.

INotel
Replace gloves at the first sign of
deterioration. VAC recommends wearing
protective gloves over Dri-Lab gloves if
working processes include handling sharp,
hot, or corrosive materials.

OXYGEN AND MOISTURE TESTING

WARNING I
VAC does not assume responsibility for
accidents resulting from mishandling of
materials used in the following tests.

VAC manufactures instruments that automatically and continuously

monitor Dri-Lab atmosphere for oxygen and/or moisture. In the
absence of more precise instrumentation, the following tests
provide a general idea of the condition of the D~i-Lab

atmosphere. Note that the ppm levels stated in these tests are
estimates only.

Electric Lightbulb Test

A. File an opening or flame torch a hole through a glass 25 W
lightbulb. Do not break filament.
B. Screw bulb into a socket and pass it into the Dri-Lab. Plug
into AC outlet in Dri-Lab junction box.
o If the filament burns out after 6 hr, the oxygen and
moisture content is higher than 5 ppm.
o If the filament burns for days (or even weeks), the
level is between 1 and 5 ppm.

Welding Chamber Test

A. Pass a portable welder and clean sample of stainless steel
into Dri-Lab.
B. Weld a bead on the clean sample of stainless steel.
o If bead is clean and silver, moisture and oxygen content
is between 1 and 2 ppm.
o If bead appears blue-black, a considerable amount of
oxygen and moisture is present.

 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _Vacuum/Atmospheres

Titanium Tetrachloride Test

A. Pass a bottle of titanium tetrachloride into Dri-Lab.
B. Open the bottle inside the glove box, but be prepared to
close the bottle immediately if you see smoke. For best
results, hold a black-gloved hand behind the bottle: the
white smoke will be better seen against the black back-
ground.
o If smoke is observed, moisture exists at a relatively
high level.
o If no smoke is observed, the dew point is less than
-60 o C (10 ppm).

Diethylzinc Test

Materials used in the following test are

pyrophoric when mixed -- use extreme
caution in handling.

A. Pass a bottle of diethylzinc, a bottle of heptane, and an

empty bottle with cap into Dri-Lab.
B. Mix a small amount of each material together in the empty
bottle, but be prepared to cover the bottle immediately if
smoke is seen. For best results, hold a gloved hand behind
the bottle: the white smoke will be better seen against the
black background.
a If there is less than 5 ppm of oxygen within the Dri-
Lab, the mixture will not emit smoke.
o If smoke is seen, a relatively high amount of oxygen
exists. Cap bottle immediately.

Section 3
OPERATIONS

GENERAL
The instructions that follow are for basic operation of the Dri-
Lab without a Dri-Train automatic recirculating system. Opera-
ting instructions for the combined Dri-Lab/Dri-Train are found in
the Dri-Train manual.

ESTABLISHING AN INERT ATMOSPHERE

A good purge is required to establish an inert atmosphere. The
purge described herein requires 200 to 250 ft 3 of gas for a
25-ft 3 box (this equals about 10 volume changes). For best
results, use as pure a gas as is available.
A. Install purge inlet and exhaust valves (user furnished) on
two ports in back of the Dri-Lab (Figure 3-1).
B. Connect gas supply to Dri-Lab inlet purqe valve.

C. Close antechamber inside door, refill valve, and evacuation

valve.
D. Open purge exhaust valve.
E. Open purge inlet valve and begin gas flow. Keep the Dri-
Lab pressure positive. The gloves must be extended to
almost horizontal, but not ballooned.
F. When purge is completed, close purge inlet valve and then
the purge outlet valve before the gloves drop. Leave a
positive pressure in the Dri-Lab.

ANTECHAMBER

Evacuate/Refill Procedure
Any time the antechamber is exposed to atmosphere, the following
procedure must be used before opening the inside antechamber door
to the glove box:
A. Both antechamber doors must be closed.
B. Refill valve must be closed.
C. Open evacuation valve and evacuate to 50 microns (minimum).
E. Close evacuation valve.
F. Open refill valve.

Since the antechamber refills from the glove box, additional gas
will be required to make up for the decrease in pressure in the
glove box. Add gas via the glove box inlet valve to make up for
this decrease in pressure.

GLOVE BOX
Be aware of the following items when using the Dri-Lab glove box:
• Watch the gloves during antechamber evacuation. If the
gloves are drawn into the glove box, check the inside ante-
chamber door and/or refill valve; either one may be open.
Close the door and refill valve to the antechamber.
• Keep the antechamber doors and valves tightly closed when
not in use.

3-2 Dri-Lab-08/85
 c ._ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _Vacuum/Atmospheres

• Never attempt to force the antechamber doors open.

• When opening the antechamber doors, back door off firmly
against the bar before raising.
• Do not allow the glove box pressure to go negative. Refill
gas into the glove box at a rate that maintains the same
volume of gas as before the antechamber was filled.

PASSING MATERIALS IN/OUT OF DRI-LAB

Passing materials into and out of the Dri-Lab are explained in
Figures 3-2 and 3-3, respectively.

Section 4
MAINTENANCE AND TROUBLESHOOTING

GENERAL
Maintenance of the HE-series Dri-Lab is uncomplicated due to
relative simplicity of the unit's design and component selection.
However, standard safe practices should always be observed during
maintenance.

Periodic Maintenance
Visual inspection of Dri-Lab O-rings, gloves, and vacuum system
should be performed to ensure tightness of glove box and proper
operation of the vacuum system. (See also Section 2-5, Leak
Test. )

Safety Glass Panels (Optional)

Refer to Safety Glass Windows in Appendix E for installation
instructions and replacement procedures.

Lexan Panels
Clean panel with a clean cloth and either soap and water or a
commercial glass cleaner.

Do not use abrasives such as steel wool,

stiff paper towels, or abrasive clean-
sers to clean panels.

To replace window or metal panels:

A. Remove 7/16-in. acorn nuts at frame and panel.
B. Clean gasket, panel, and box and apply a light coat of
vacuum grease to gasket. Replace worn or damaged gaskets.
C. Replace panel and frame over the gasket onto the box studs,
andcinstall acorn nuts at 26 to 28 in.-lb torque.
D. Leak check all joints.

4-1 Dri-Lab-08/85
 c _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Vacuum/Atmospheres

Dri-Lab
Use mild soap and water to clean the outside painted surfaces.
Dry the unit with compressed air. At recommended 3-mo intervals,
all valves, fittings, lines, tubing, and connections should be
inspected for general mechanical and electrical integrity.

Antechamber
Check the sealing a-rings periodically and replace when worn or
damaged. Clean antechamber doors periodically with a mild
solvent, and coat the sealing surfaces with a light coat of
vacuum grease. If required, adjust antechamber door tension as
follows:
A. Close door and loosen jam nut at door clamp (Figure 4-1).
Loosen nut 2.
B. Open door and rotate door clockwise (increase tension) or
counterclockwise (decrease tension).
C. Close door to fully closed position - firm pressure should
be required to close door.
D. Tighten nut 2 and then jam nut.

Replacing Old Gloves

Gloves should be replaced at the first sign of deterioration. To
replace old gloves with a minimum of Dri-Lab contamination:
A. Seal glove port with internal glove port cover (optional
equipment).
B. Remove glove by reversing the procedure for installing
gloves as outlined in Section 2-4.
C. Install new glove as outlined in Section 2-4.
D. Before installing clamp, purge glove as follows:
1) Increase and maintain positive pressure in glove box at
approximately 4-in. water column.
2) Loosen glove port cover to allow glove to fill with
inert gas from glove box.
3) Once glove is pressurized, tighten glove port cover
again.

4-2 Dri-Lab-08/85

glove box atmosphere. If adjusting inside door,
evacuate and refill Antechamber using your standard
pump down time.

1 .)Tension Door Adjustment:

A)Close door and loosen nut 2 (J) close to the
door clamp (F). Never loosen nut 1 (H) (Figure 4-1).
B)Release door clamp (F), until door will turn.
C)Turn door (C) (clockwise CW to increase tension),
(counterclockwise CCW to decrease tension).
D)Close door clamp (F) fully. Firm pressure should
be required to close door. This may require several
movements of the door (C) to increase or decrease
the tension required to close the door.
E)Close door clamp (F) fully then tighten nut 2 (J).

2.)Adjustinq L Replacing Door Clamp:

 Detai1ed Instruction For
Antechamber Door Adjustment

! !NOTE! !
Use a clamp on the end of the door bar (E) at the door
boss close to the window. This will keep the door bar
from flying up and back to the door stop, because of
the balance weight (D) and no door for counter balance.

D)To replace door clamp (F), install jam nut (K) until
it is fully seated against the door clamp shoulder.
E)Open the door clamp (F) fully then slowly turn CW
until you have engaged the threads in the door bar
(E). Now close the door clamp slowly to pick up the
door screw (G) while turning the door clamp CWo Let
the door handle move freely while turning. Turn the
door handle until it is as close to the door bar (E)
as possible. Now return the handle to the original
position and tighten jam nut (K) against door bar.
F)Refill antechamber and go to Tension Adjustment on
page one.

3. ) Adjustinq Counter Ba1ance Spring (Dri-Labs 1989 and Newer)

A)Open door clamp (F). Do not raise door bar (E).
B)Place your 3/4 inch open end wrench on flats of
the door boss spring holder located at the door
hinge point. (Note the present location of the
screw holding the end of the spring for a
reference point).
C)Holding the 3/4 inch open end wrench with one
hand, use your other hand, with the 9/16" box end
wrench loosen the 9/16 inch bolt by turning it CCW.
D)Now you are ready to adjust the Counter Balance
Spring. You turn the door boss spring holder with
the 3/4 inch open end wrench so that the door bar
(E) will stay balance and horizontal with the floor
of the Dri-Lab. Tighten the 9/16 inch bolt before
releasing pressure on the 3/4 inch wrench for each
adjustment.

service or use.

The following guidelines and procedures for disassembly and decontamination of ROTRON blowers must
be completed before a Return Material Authorization (RGA) number can be issued.

Disassembly Procedure

It is recommended that the following guidelines and procedures be reviewed and approved by your
company Health & Safety Officer or other company official. These considerations should include a review
of material safety sheets (MSDS') of all materials the ROTRON blower has been exposed to before it is

5. Appropriate safety equipment and material.
6. #2 Phillips screwdriver
7. #3 Phillips bit and impact type screwdriver

Steps

1. Remove the two end cap retainer screws using the 3/8 socket and the 3/8 open end wrench

2. Using the mallet to remove the end caps, strike the end caps outwards at the point where the retainer
screws were located. You must work on one side at a time, back and forth on the retainer point.

3. After removing both end caps, use the 5/32 Allen wrench on the center screw turning it (CAW) to
loosen the impeller from the shaft.

4. There are three #2 Phillips screws on one end. Remove the screws and the small retainer cap. Next,
remove the four large Phillips screws using the impact screwdriver.
