Operation
Pressure Relief Procedure
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.
WARNING
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.
Flushing
To reduce the risk of fluid injection injury, static
sparking, or splashing, relieve pressure, hold a metal
part of the dispensing valve firmly to the side of a
grounded metal pail and use the lowest possible fluid
pressure during flushing.
1. Before connecting the supply lines to the supply
tank, flush the pump and supply line with a
compatible solvent.
2. Connect the supply line to a solvent supply. Turn
on the main air, open the bleed-type master air
valve, and slowly open the pump air regulator until
the pump is cycling slowly. Use the lowest possible
pressure, and flush until the lines are thoroughly
cleaned. Shut off the pump, and relieve the
pressure.
INJECTION HAZARD
To reduce the risk of serious injury
whenever you are instructed to relieve
pressure, always follow the Pressure
Relief Procedure above.
WARNING
3. Disconnect the solvent supply, and connect the
supply lines to the tank.
4. Connect the fluid supply hose from the pump to
the dispensing valve.
Operating
WARNING
Never exceed 180 psi (12.6 bar) Maximum Air
Pressure to these pumps. Using higher air
pressure will cause the pump to overpressurize,
which may result in component rupture, fire, or
explosion and cause serious bodily injury.
1. Open the bleed-type master air valve.
2. Slowly open the pump air regulator until the pump
is running smoothly.
3. Open the dispensing valve, and allow the system
to prime. When the system is fully primed, the
pump starts and stops as the dispensing valve is
opened and 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.
CAUTION
4. Use the air regulator to control pump speed and
fluid pressure. Always use the lowest possible
pressure, which reduces pump wear.
5. When shutting off the system, and before checking
or servicing it, relieve the pressure.
INJECTION HAZARD
To reduce the risk of serious injury
whenever you are instructed to relieve
pressure, always follow the Pressure
Relief Procedure at left.
