Typical Installation
The Typical Installations shown on page 6 are only
guides to selecting and installing accessories and
components. For designing a system to suit your
needs, contact your Graco representative.
1. Mount the pump (1) onto the pail.
a. For Model 992–706 (35 lb size), place the
cover (17) on the pail and secure it with the
three thumbscrews. Lower the pump into the
pail through the hole in the cover, and secure
with the two screws (41) and washers.
b. For Model 992–714 (400 lb size) , tighten the
bung adapter (29) in the cover's bung hole,
then adjust the pump so its intake valve is
1/2 in. (13 mm) off the bottom of the drum.
Tighten the bung adapter thumbscrews to hold
this position.
2. Install the 3/8 npt nipple (161) in the pump fluid
outlet. Install the union (7) in the inlet of the fluid
filter (A). Connect the union to the nipple, with the
head of the filter facing down as shown on
page 6.
3. Install the 1/4 npt nipple (14) in one outlet of the
filter. Install the swivel (23) at the fluid inlet on the
spray gun (21). Connect the filter outlet nipple to
the gun swivel, using the 15 ft coupled hose (20)
4. Install the drain line.
a. For Model 992–706, install the ball valve (16)
into one of the outlets of the filter (A). Install
the o-ring (39) on the plug (19), and install the
plug in the cover hole. Secure with
setscrews (40). Screw the street elbow (15)
into the plug and install the 1/4 npt nipple (14)
into the elbow. Install couplings (26) on both
ends of the nylon hose (25). Connect the hose
to the plumbing on the cover and the ball valve
on the filter. Use the pipe plugs (27 and 28) to
close off the unused filter outlets.
b. For Model 992–714, screw the street
elbow (15) into the filter outlet as shown on
page 6. Screw the ball valve (16) into the
street elbow. Insert the bushing (32) into the
hole in the drum cover, and screw the swivel
union (31) into the bushing. Connect the male
end of the 3 ft. (.9 m) coupled hose (30) to the
swivel union, and connect the female end to
the ball valve of the filter. Close off the unused
filter outlets with the plugs (27 and 28).
Installation
5. Install the air line accessories in the order shown
on page 6. Install a pump runaway valve (F)
closest to the air pump to shut off the air to the
pump if the pump accelerates beyond the pre-ad-
justed setting. A pump which runs too fast can be
seriously damaged.
6. Next, install an air line lubricator (D) for automatic
air motor lubrication, a bleed-type master air
valve (B) to relieve air trapped between the valve
and the pump, an air regulator (2, supplied) to
control the pump speed, and an air line filter (C) to
remove harmful dirt and moisture from the com-
pressed air supply.
Required in your system are a bleed-type master
air valve (B) and a fluid drain valve (16). These
components help reduce the risk of serious injury
including fluid injection, splashing in the eyes or on
the skin, and injury from moving parts if you are
adjusting or repairing the pump.
The bleed-type master air valve relieves air trapped
between the valve and the pump after the pump is
shut off. Trapped air can cause the pump to cycle
unexpectedly and result in serious injury, including
amputation. Locate the valve within easy reach of
the pump.
The fluid drain valve, which is supplied with your
system, helps relieve pressure in the displacement
pump, hose, and gun when shutting off the pump.
Triggering the gun to relieve pressure may not be
sufficient, especially if there is a clog in the hose,
gun, or spray tip.
7. Be sure the air line (E) is properly grounded, and is
large enough to supply an adequate volume of air
to the motor.
8. Install the air line ball valve (3, supplied) on the air
line, upstream from the accessories. Screw the air
line fitting (H, supplied) into the air line filter inlet.
Attach the air line coupler (4, supplied) to the end
of the air line, but do not attach it to the air line
fitting yet.
