Installation
General Information
• The Typical Installation shown in FIG. 3 is
only a guide for selecting and installing sys-
tem components. Contact your Graco dis-
tributor for assistance in planning a system
to suit your needs.
• Installation and use must be in accordance
with the American and/or Canadian
National Standards for Natural Gas Oper-
ated Diaphragm Pumps (ANSI LC 6-2008,
CSA TIL R-14) and must comply with all
local, state, and federal codes.
• If the diaphragm ruptures, natural gas may
mix with the fluid being pumped. Take
appropriate precautions.
Tighten Fasteners Before Setup
Before using the pump for the first time, check
and retorque all external fasteners. See
Torque Instructions, page 16.
Mounting
1. Be sure the mounting surface can support
the weight of the pump, hoses, and acces-
sories, as well as the stress caused during
operation.
2. Mount in an upright, horizontal position as
shown in FIG. 3.
3. For all mountings, be sure the pump is
bolted directly to the mounting surface.
4. For ease of operation and service, mount
the pump so air valve, gas inlet, fluid inlet
and fluid outlet ports are easily accessible.
5. Rubber Foot Mounting Kit 236452 is avail-
able to reduce noise and vibration during
operation.
Grounding
The equipment must be grounded. Grounding
reduces the risk of static and electric shock by
providing an escape wire for the electrical cur-
rent due to static build up or in the event of a
short circuit.
Pump: See FIG. 1. Loosen the grounding
screw (GS). Insert one end of a 12 ga. mini-
mum ground wire (R) behind the screw and
tighten the screw securely. Connect the clamp
end of the ground wire to a true earth ground.
A ground wire and clamp, Part 238909, is
available from Graco.
• This pump exhausts natural gas and must
be ventilated to a remote area. See
Exhaust Ventilation on page 10.
• Never lift a pump under pressure. If
dropped, the fluid section may rupture.
Always follow the Pressure Relief Proce-
dure on page 14 before moving or lifting
the pump.
This pump must be electrically grounded
using the grounding conductor provided.
Improper grounding can cause hazardous
operation.

Installation
313598H 9
Gas and fluid hoses: Use only grounded
hoses with a maximum of 500 ft (150 m) com-
bined hose length to ensure grounding
continuity.
Solvent pails used when flushing: Follow
local code. Use only conductive metal pails,
placed on a grounded surface. Do not place
the pail on a nonconductive surface, such as
paper or cardboard, which interrupts ground-
ing continuity.
Fluid supply container: follow local code.
Suction device nozzle: must be bonded to
metal container from which it is suctioning by
firm metal-to-metal contact to a properly
grounded suction hose and pump.
Piping, valves, and fittings: use only electri-
cally conductive materials. Bond and ground
per code.
Check your system electrical continuity after
the initial installation, and then set up a regular
schedule for checking continuity to be sure
proper grounding is maintained.
Gas Line
See FIG. 3, page 11.
1. Install a regulator (C) and gauge to control
the fluid pressure. Locate it close to the
pump.
2. Locate a bleed-type master gas valve (B,
required in your system) close to the pump
and use it to relieve trapped natural gas. Be
sure the valve is easily accessible from the
pump and located downstream from the
regulator.
3. Locate another bleed-type master valve (E)
upstream from all natural gas line accesso-
ries and use it to isolate them during clean-
ing and repair.
4. A filter (F) removes harmful dirt and mois-
ture from the compressed gas supply.
5. Install a grounded, flexible gas hose
between the accessories and the 1/2 in.
npt(f) pump inlet (D). See FIG. 3. Use a
minimum 1/2 in. (13 mm) ID hose.
FIG. 1. Ground Screw and Wire
GS R
ti12214a
Trapped gas can cause the pump to cycle
unexpectedly, which could result in serious
injury from splashing.

Installation
10 313598H
Exhaust Ventilation
The gas exhaust port is 3/4 npt(f). Do not
restrict the gas exhaust port. Excessive
exhaust restriction can cause erratic pump
operation.
1. Remove the muffler (T) from the pump gas
exhaust port.
2. Install a grounded exhaust hose (U) and
connect the muffler (T) to the other end of
the hose. The minimum size for the
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
bends or kinks in the hose.
3. Place a container at the end of the exhaust
line to catch fluid in case a diaphragm rup-
tures. Locate the container away from all
sources of ignition, including pilot lights and
waste materials. If the diaphragm ruptures,
the fluid being pumped will exhaust with the
natural gas.
Be sure to read and follow the TOXIC FLUID
OR FUMES HAZARD warning, page 7, and
FIRE AND EXPLOSION HAZARD warning,
page 5, before operating this pump. You
must vent the exhaust to a safe location,
such as away from people, animals, food
handling areas, and all sources of ignition.
Vent in accordance with local codes, or in the
absence of local codes, an industry or
nationally recognized code having jurisdic-
tion over the specific installation.
