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.
