WARNING

Installation

313598C 7

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 15.

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 9.

• Never lift a pump under pressure. If

dropped, the fluid section may rupture.

Always follow the Pressure Relief Proce-

dure on page 13 before moving or lifting

the pump.

This pump must be electrically grounded

using the grounding conductor provided.

Improper grounding can cause hazardous

operation.

Installation

8313598C

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 10.

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

313598C 9

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 6, and

FIRE AND EXPLOSION HAZARD warning,

page 4, 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.
