Operation
WARNING
PRESSURIZED EQUIPMENT HAZARD
This is a pressurized tank.
Alway
s
follow the
Pres-
sure Relief Procedure
on page 5 before opening
the tank cover or fill port. This reduces the risk of
serious injury, including splashing in the eyes or on
the skin, or injury from moving parts. These injuries
can result if the tank pressure is not fully relieved.
Preparing the Fluid
Prepare the fluid according to the manufacturer’s
instructions. Strain the fluid to remove large particles
that could clog the spray gun or the siphon tube.
Filling the Tank
1.
Before filling the tank, follow the
Pressure Relief
Procedure
on page 5.
2.
Place fluid into the tank by one of the following
methods:
a.
Remove the cover and place a 2-gallon
antistatic polyethylene liner in the tank. Pour
the fluid into the antistatic polyethylene liner
(see
Accessories
, page 18).
b.
Fill the tank through the fill port in the cover, or
remove the cover and pour fluid directly into
the tank.
3.
Replace the cover and tighten the c-clamp handles
securely.
Operating the Pressure Tank
(
See Fig. 2.)
1.
Close the tank air regulator (J) by turning the knob
counterclockwise
and turn on the air supply.
WARNING
Overpressurizing the tank or accessories could
cause a part to rupture. To reduce the risk of
serious injury, including splashing in the eyes or on
the skin and property damage, never exceed the
maximum air and fluid working pressure of the
lowest-rated component in your system.
2.
Open the air inlet ball valve (15).
CAUTION
Do not operate the agitator at a high speed for a long
period of time. Excessive agitator speed can cause
foaming of fluid (making the fluid unusable), vibra-
tion, and increased wear on the parts. Always agitate
the fluid only enough to maintain even mixing.
3.
Start and adjust the agitator:
a.
Slowly open the needle valve (113).
b.
Adjust the speed of the agitator, with the
needle valve, to about 40 to 60 rpm.
4.
Adjust the tank air regulator (J) to the approximate
pressure desired.
5.
Open fluid outlet ball valve (K).
6.
Turn on the atomizing air to the air spray gun. Test
spray a small area and adjust the pressure as
necessary. Always use the lowest possible air
pressure to obtain the desired results.
Safety Relief Valve
A safety relief valve (12) will automatically relieve the
tank pressure when the air pressure exceeds 95 to
100 psi (0.5 to 0.6 MPa, 6.5 to 7 bar). Refer to Fig. 2
or the parts drawings.
Each week, check the working order of the safety relief
valve.
Only as a test
, raise the air pressure to 95 to
105 psi (0.5 to 0.6 MPa, 6.5 to 7.1 bar). If the safety
relief valve does not relieve the pressure, replace it
immediately. Do not attempt to repair it. The safety
relief valve will reset automatically when the pressure
is relieved.
