Installation
General
Be sure that all operators read and understand this
entire manual and the separate manuals supplied with
components and accessories before using this equipment.
Reference numbers and letters in parentheses refer to
the illustrations and the parts lists on pages 16–23.
Accessories mentioned in the text are available from
your Graco distributor. If you supply your own accessories, be sure they are adequately sized to meet your
system’s requirements.
The Typical Installation shown in Fig. 2 is only an
example. For assistance in designing a system to meet
your particular needs, contact your Graco distributor.
System Accessories
Refer to Fig. 2. Install an air line filter (A) in the main
air line (B), to remove harmful dirt and moisture from
the compressed air supply. To provide automatic
lubrication of the air motor, install an air line lubricator
(C) downstream from the pump air regulator (31).
Install a second bleed valve (G) in the main air line, to
isolate the accessories for servicing.
Grounding
To reduce the risk of static sparking, ground the pump,
object being sprayed, and all other spray equipment
used or located in the spray area. Check your local
electrical code for detailed grounding instructions for
your area and type of equipment. Be sure to ground all
of this spray equipment.
1. Pump: loosen the grounding lug locknut (W) and
washer (X). Insert one end of a 1.5 mm2 (12 ga)
minimum ground wire (Y) into the slot in lug (Z)
and tighten the locknut securely. See Fig. 1. Connect the other end of the wire to a true earth
ground. Order Part No. 237569 Ground Wire and
Clamp.
2. Air hoses: use only electrically conductive air
hoses.
3. Fluid hoses: use only electrically conductive fluid
hoses.
4. Heater, if used: refer to the Viscon2 Heater manual, 307805.
5. Air compressor: follow manufacturer’s recommendations.
6. Spray gun: grounding is obtained through connection to a properly grounded fluid hose and pump.
7. Fluid supply container: according to your local
code.
8. Object being sprayed: according to your local
code.
9. All solvent pails used when flushing, according to
local code. Use only metal pails, which are conductive, placed on a grounded surface. Do not
place the pail on a non-conductive surface, such
as paper or cardboard, which interrupts the
grounding continuity.
10. To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the
spray gun firmly to the side of a grounded metal
pail, then trigger the spray gun.

WARNING
Three required components are supplied in your
system, to help reduce the risk of serious injury
including fluid injection, splashing in the eyes or on
the skin, overpressurization, or injury from moving
parts if you area adjusting or repairing the pump.
The bleed-type master air valve (62) relieves air
tapped between this valve and the pump. Trapped
air can cause the pump to cycle unexpectedly. To
bleed air from the pump, the pump air regulator
must be open when you close this valve.

Hose and Gun Connections
Refer to the Typical Installation drawing (Fig. 2). Connect one end of the fluid hose (D) to the filter (25)
outlet and the other to the fluid inlet of the gun (E). Do
not install the spray tip in the gun yet. To use a second
gun with the sprayer, refer to pages 11–13.
Close the bleed-type master air valve (62) and both
the air regulators (31). Connect the main air line (B) to
the bleed valve. Connect an air supply hose (F) to the
outlet nipple of the gun (left) air regulator. Connect the
other end of the hose to the gun’s air inlet.
The air relief valve (52) opens automatically to
relieve air pressure to the pump if the the pressure
exceeds a preset level. This vale prevents overpressurization of the spray gun.
The fluid drain valve (65) assists in relieving fluid
pressure in the displacement pump, hose, and gun;
triggering the gun to relieve pressure may not be
sufficient.
