Pressure Relief Procedure
WARNING
INJECTION HAZARD
To reduce the risk of serious bodily
injury, including fluid injection, injury from
moving parts, or splashing in the eyes or
on the skin, always follow this procedure whenever
you shut off the pump, when checking or servicing
any part of the system, when installing or changing
dispensing devices, and whenever you stop dis-
pensing.
1. Close the air regulator and disconnect the air
supply hose.
2. Close the pump's bleed-type master air valve
(required in the system).
3. Open the dispensing valve until pressure is fully
relieved.
If you suspect that the dispensing valve is clogged, or
that pressure has not been fully relieved after following
the steps above, very slowly loosen the dispensing
valve coupler or hose end coupling to relieve pressure
gradually, then loosen completely.
Operating
WARNING
Never exceed 180 psi (12.6 bar) Maximum Air
Pressure to these pumps. Using higher air
pressure will cause the pump to over pressurize
which may result in component rupture, fire, or
explosion and cause serious bodily injury.
NOTE: Read and follow the warnings and instructions
in the manual for each of the system components.
1. Close the air regulators and bleed-type master air
valves to all but one pump.
2. Open the master air valve from the compressor.

Operation
3. For the pump that is connected, trigger the
dispensing valve into a grounded metal waste
container, making firm metal-to-metal contact
between the container and valve. Open the
bleed-type master air valve and open the pump air
regulator slowly, just until the pump is running.
When the pump is primed and all air has been
pushed out of the lines, release the trigger.
4. If you have more than one pump, repeat this
procedure for each pump.
5. When the pump is primed and has sufficient air
supplied to it, it starts when the dispensing valve is
opened and shuts off when it is closed.
Never allow the pump to run dry of the fluid
being pumped. A dry pump will quickly
accelerate to a high speed and possibly damage
itself. If the pump accelerates quickly, stop it
immediately, and check the fluid supply. If the
supply container is empty and air has been
pumped into the lines, prime the pump and lines
with fluid, or flush it and leave it filled with a
compatible solvent. Be sure to eliminate all air
from the fluid system.
6. Set the air pressure to each pump at the lowest
pressure needed to get adequate fluid delivery.
7. When shutting off the system, and before checking
or servicing it, relieve the pressure.
