Pressure Relief Procedure
WARNING
INJECTION HAZARD
The equipment stays pressurized until
pressure is manually relieved. To reduce
the risk of serious injury from pressur-
ized fluid, accidental spray from the valve or
splashing fluid, follow this procedure whenever you:
are instructed to relieve pressure,
stop dispensing,
check, clean or service any system equipment,
install or clean dispensing devices.
1. Close the pump air regulator and the bleed-type
master air valve (required in your system).
2. Hold a metal part of the dispensing valve firmly to
a grounded metal waste container and trigger the
valve to relieve the fluid pressure.
Startup
1. If there are multiple pumps on the air line, close
the air regulators and bleed-type master air valves
to all but one pump. If there is only one pump,
close its air regulator and bleed-type master air
valve.
2. Open the master air valve from the compressor.
3. For the pump which is supplied with air, open the
dispensing valve into a grounded metal waste con-
tainer, making firm metal-to-metal contact between
the container and valve. Open the bleed-type mas-
ter 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, close the dispense valve.
4. If you have more than one pump, repeat this pro-
cedure for each pump.
NOTE: When the pump is primed, and with sufficient
air supplied, the pump starts when the dispensing
valve is opened and shuts off when it is closed.
5. Set the air pressure to each pump at the lowest
pressure needed to get the desired results.

Operation

izing any component in the system, be sure you
know the maximum working pressure of each com-
ponent. Never exceed the maximum working pres-
sure of the lowest rated component in the system.
Overpressurizing any component can result in rup-
ture, fire, explosion, property damage, and serious
injury.
To determine the fluid output pressure using the air
regulator reading, multiply the ratio of the pump by
the air pressure shown on the regulator gauge. For
example:
[50 (:1) ratio x 7 bar air = 350 bar fluid output]
Limit the air to the pump so that no air line or fluid
line component or accessory is overpressurized.
6. Never allow the pump to run dry of the material
being pumped. A dry pump will quickly accelerate
to a high speed, possibly damaging itself. If your
pump accelerates quickly, or is running too fast,
stop it immediately and check the material supply.
If the supply container is empty and air has been
pumped into the lines, prime the pump and lines
with material, or flush it and leave it filled with a
compatible solvent. Be sure to eliminate all air
from the material lines.
NOTE: A pump runaway valve (G) can be installed on
the air line to automatically shut off the pump if it starts
to run too fast.
7. Read and follow the instructions supplied with
each component in your system.
8. To shut off the system, always follow the Pressure
Relief Procedure Warning, at the left.
WARNING
COMPONENT RUPTURE HAZARD
The maximum working pressure of each
component in the system may not be the
same. To reduce the risk of overpressur-
