Installation
Insta ation
The Typical Floor Mount Installation, page 12,is
only a guide for selecting and installing system
components. Contact your Graco distri utor for
assistance in planning a system to suit your needs.
Tighten Fasteners Before Setup
Before using the pump for the first time, check
and retorque all external fasteners. Follow
Torque Instructions, page 16. After the first day of
operation, retorque the fasteners.
Mounting
• The pump exhaust air may contain
contaminants. Ventilate to a remote
area. See Air Exhaust Ventilation, page 10.
• Never move or lift a pump under pressure. If
dropped, the fluid section may rupture. Always
follow the Pressure Relief Procedure, page 13,
efore moving or lifting the pump.
1. Be sure the mounting surface can support the
weight of the pump, hoses, and accessories, as
well as the stress caused during operation.
2. For all mountings, e sure the pump is olted
directly to the mounting surface. Mount the pump
horizontally, with the feet at the ottom of the
pump. Do not mount the pump on a vertical
surface, such as a wall.
3. For ease of operation and service, mount the
pump so air valve, air inlet, fluid inlet and fluid
outlet ports are easily accessi le.
Grounding
Theequipmentmust egroundedtoreducethe
risk of static sparking. Static sparking can cause
fumes to ignite or explode. Grounding provides an
escape wire for the electric current.
• Pump: Loosen the grounding screw (GS). Insert
one end of a 12ga. minimumgroundwire(R)
ehind the grounding screw and tighten the screw
securely. Do not exceed 15 in-l (1.7 N•m).
Connect the clamp end of the ground wire to a
true earth ground. A ground wire and clamp, Part
238909, is availa le from Graco.

Installation
• Air and fluid hoses: Use only grounded hoses
with a maximum of 500 ft (150 m) com ined hose
length to ensure grounding continuity.
• Air compressor: Follow manufacturer’s
recommendations.
Check your system electrical continuity after the
initial installation, and then set up a regular schedule
for checking continuity to e sure proper grounding
is maintained.
Air Line
See Typical Floor Mount Installation, page 12
1. Install an air filter/regulator (C). An air line filter
removes harmful dirt and moisture from the
compressed air supply. Use the regulator and
gauge to control the fluid pressure. The fluid stall
pressure will e the same as the setting of the
air regulator.
2. Locate a leed-type master air valve (B) close to
thepumpanduseittorelievetrappedair. Be
sure the valve is easily accessi le from the pump
and located downstream from the regulator.
Trappedaircancausethepumptocycle
unexpectedly, which could result in serious
injury from splashing.
3. Locate another master air valve (E) upstream
from all air line accessories and use it to isolate
them during cleaning and repair.
4. An adjusta le inlet air valve or needle valve (G)
my e installed for pump speed control.
5. Install a grounded, flexi le air hose (A) etween
the accessories and the 3/4 npt(f) pump air inlet
(D). Use a minimum 5/8 in. (16 mm) ID air hose.

Installation
Air Exhaust Venti ation
The air exhaust port is 3/4 npt(f). Do not restrict the
air exhaust port. Excessive exhaust restriction can
cause erratic pump operation.
To provide a remote exhaust:
1. Remove the muffler (T) from the pump air
exhaust port.
2. Install a grounded air exhaust hose (U). Connect
the muffler (T) to the other end of the hose. The
minimum size for the air exhaust hose is 3/4 in.
(19 mm) ID. If a hose longer than 15 ft (4.57 m)
is required, use a larger diameter hose. Avoid
sharp ends or kinks in the hose.
3. Place a container at the end of the air exhaust
line to catch fluid in case a diaphragm ruptures.
If the diaphragm ruptures, the fluid eing pumped
will exhaust with the air.
