System Accessories
CAUTION
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 to break. Provide a bracket on which to
mount the accessories.
NOTE: Install the following accessories in the order
shown in Fig. 1.
Four accessories are required in your system: an
air shut-off valve/air bleed device, fluid drain valve,
thermal relief kit, and ground wire. These accesso-
ries help reduce the risk of serious bodily injury
including fluid injection, splashing in the eyes or on
the skin, injury from moving parts if you are adjust-
ing 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 unex-
pectedly, causing serious bodily injury if you are
adjusting or repairing the pump. Use either a
bleed-type master air valve (A) or a quick-discon-
nect coupler (M) and 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 valve to relieve
pressure may not be sufficient.
The thermal relief kit assists in relieving pressure in
the pump, hose, and dispensing valve due to heat
expansion.
The ground wire reduces the risk of static sparking.
WARNING
D Screw the muffler (5) into the 3/4-in. npt muffler
port, and tighten it using a wrench on the flats of
the muffler near the male threads.
D Install an air line lubricator (N) for automatic air
motor lubrication.
D Install the air regulator (C) to control pump speed
and pressure.
D Install an air line filter (B) to remove harmful dirt
and contaminants from your compressed air supply.
D Install a bleed-type master air valve (A) to isolate
the accessories for servicing. See Fig. 1. To order
a bleed-type master air valve, order Part No.
107142.
As an alternative to a bleed-type master air valve,
you can install an air line quick disconnect coupler
(M) and fitting (L) to serve as an air-bleed device.
See Detail A in Fig. 1.
D Install a ball valve (F), at the end of a line drop, as
shown in Fig. 1, for releasing moisture that collects
in the line.
D 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.
D 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-in. npt(f)
inlet and outlet pump runaway valve, order Part No.
215362.
D Install a thermal relief kit (K) on the dispensing
valve side of the pump. To order a 1600 psi
(110 bar) thermal relief kit, order Part No. 240429.
D Install a suitable fluid hose (P) and dispensing
valve (J).
Wall Mount
The pump shown in Fig. 1 is a wall-mounted universal
pump, Model 205626. To order the wall-mounting
bracket shown, order Part No. 238245.
Cover Mount
Pump Model 222065 is designed for mounting directly
on a 55-gallon drum cover. When the pump is
mounted to a closed-head drum, be sure you loosen
the vent plug on the drum cover to prevent a vacuum
in the drum. For cover mounting, see the Mounting
Hole Layout on page 16.
Bung Mount
Pump model 222095 is designed for bung mounting on
a 55-gallon drum. The bung adapter (153) is shown in
the Parts Drawing on page 15.
