Air Line and Accessories
NOTE:
Install air line accessories in the order shown in
the Typical Installation.
•
Install a pump runaway valve (G) to shut off the air
to the pump if the pump accelerates beyond the
pre-adjusted setting. A pump that runs too fast can
be seriously damaged.
•
Install an air line lubricator (F) for automatic air
motor lubrication.
•
Install a bleed-type master air valve (H) to relieve air
trapped between the valve and the motor when the
valve is closed.
•
Install the air regulator (C) to control pump speed
and pressure.
•
On the main air supply line from the compressor,
install an air line filter (E) to remove harmful dirt and
contaminants from the compressed air supply.
•
For Models 240880 through 240886
, install the
provided air regulator/safety valve (K) at the pump
air inlet with the nipple (7a, also included).
Operation
Pressure Relief Procedure
1. Shut off the air to the pump.
2. Bleed off the air pressure by closing the air regulator
(self-relieving type), or closing the bleed-type mas-
ter air valve installed upstream of the air regulator,
or disconnecting the air supply hose at the
quick-disconnect.
3. Hold a metal part of the gun or valve firmly to the
side of a grounded metal waste container and trig-
ger to relieve fluid pressure.
Start-up: Single or Multiple
Pump Systems
1. Close the air regulator and bleed-type master air
valves to all but one pump.
2. Open the master air valve from the compressor.
3. For the pump which is connected, trigger the dis-
pensing valve into a grounded metal waste con-
tainer, making firm metal-to-metal contact between
the container and valve.
4. Open the bleed-type master air valve, and open the
pump air regulator slowly until the pump is running.
When the pump is primed and all air has been
pushed out of the lines, release the trigger.
5. If you have more than one pump, repeat this proce-
dure 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.
Trapped air can cause the air motor to cycle
unexpectedly, causing serious injury if you are
adjusting or repairing the pump. Follow the
Pressure
Relief Procedure
on page 10.
NOTICE
Avoid hanging air accessories directly on the pump
air inlet. The fittings are not strong enough to support
the accessories and may cause one or more to
break. If accessories must be installed directly on the
pump, provide a bracket on which to mount them.
