System Accessories

NOTICE
Do not hang the air accessories directly on the air inlet
(E). The fittings are not strong enough to support the
accessories and may cause one or more valves to
break. Provide a bracket to mount the accessories.
Install the accessories shown in F
Four accessories are required in the system: an air
shut-off valve bleed device, fluid drain valve, thermal
relief kit, and ground wire. These accessories help
reduce the risk of serious bodily injury including skin
injection, splashing in the eyes or on the skin, injury
from moving parts if adjusting or repairing the pump,
and explosion from static sparking.
The air bleed device relieves air trapped between it
and the air motor after the air supply is shut off.
Trapped air can cause the air motor to cycle
unexpectedly, causing serious bodily injury when
adjusting or repairing the pump. Use either a
bleed-type master air valve (A) or a quick-disconnect
coupler (M) with male quick-disconnect pin fitting (L).
Install near the pump air inlet, within easy reach of
the pump.
The fluid drain valve (H) assists in relieving fluid
pressure in the displacement pump, hoses and
dispensing valve. Triggering the dispensing valve (J)
to relieve pressure may not be sufficient.
The thermal relief kit (K) assists in relieving pressure
in the pump, hose, and dispensing valve due to heat
expansion.
The ground wire (Y) reduces the risk of static
sparking.

• Insert the muffler (5) into the 3/4 npt muffler port
and tighten using a wrench on the flats of the
muffler near the male threads.
• Install an air line lubricator (N) for automatic air
motor lubrication.
• Install an air regulator (C) to control the pump
speed and pressure.
• Install an air line filter (B) to remove harmful dirt and
contaminants from the compressed air supply.
• Install bleed-type master air valve (A) to relieve air
trapped between it and the motor when the valve is
closed, and to isolate the accessories for servicing.
See F . 1. To order a bleed-type master air valve,
IG
order Part No. 107142.
As an alternative to a bleed-type master air valve,
installation of an air line female quick-disconnect
coupler (M) and male quick-disconnect pin fitting
(L) (see F . 1) can serve as an air-bleed device.
IG
• Install a ball valve (F) at the end of the line drop for
releasing moisture that collects in the line (F
• Install a drain valve (H) near the pump fluid outlet to
relieve fluid pressure in the hoses and gun when
opened. To order a fluid drain valve, order Part No.
210658.
• Install a pump runaway valve (D) to shut off the air
to the pump if the pump accelerates beyond the
pre-adjusted setting, which can be caused by a
depleted fluid supply. A pump that runs too fast can
be seriously damaged. To order a 3/4 npt(f) inlet
and outlet pump runaway valve, order Part No.
215362.
• Install a thermal relief kit (K) on the dispensing valve
side of the pump. To order a 1600 psi (11 MPa, 110
bar) thermal relief kit, order Part No. 240429.
• Install a suitable fluid hose (P) and dispensing valve
(J).
