Installation
Mounting the Pump
• Selection a convenient location for the equipment to
ensure easy operator access to the pump air con-
trols, sufficient room to change supply containers,
and a secure mounting platform.
• If you are mounting the pump directly on the supply
tank, position the pump so its intake valve is no
more than 1 inch (25 mm) from the bottom of the
container. Mount the pump to the cover or other suit-
able mounting device.
Grounding
Be sure to ground all of this equipment:
Pump: Use a ground wire and clamp as shown in F
IG. 1.
Remove the ground screw (Z) and insert through the
eye of the ring terminal at end of ground wire (Y). Fasten
the screw back onto the pump and tighten securely.
Connect the other end of the wire to a true earth ground.
To order a ground wire and clamp, order Part No.
222011.
Air and fluid hoses: Use only electrically conductive
hoses.
Air compressor: Follow manufacturer’s recommenda-
tions.
Dispensing valve: Ground through connection to a
properly grounded fluid hose and pump.
Object being dispensed to: Follow your local code.
Solvent pails used when flushing: Follow your local
code. use only metal pails, which are conductive, placed
on a ground surface. Do not place the pail on a non-con-
ductive surface, such as paper or cardboard, which
interrupts the grounding continuity.
To maintain ground continuity when flushing or
relieving pressure: Hold a metal part of the dispensing
valve firmly to the side of a grounded metal pail, then
trigger the gun.
Typical Installation
Mount the pump to suit the type of installation planned.
Very heavy lubricants may require an inductor plate.
See Dimensions and Mounting Hole Layout on page 17.
Install the air line accessories in the approximate order
shown in F
IG. 2. Install a bleed-type master air valve (B)
within easy reach of the pump, upstream from the air
regulator (E). Install an air filter (C) to remove harmful
dirt and moisture from your compressed air supply. For
automatic air motor lubrication, install an air line oiler (D)
close to the pump air inlet. Install and air regulator (E) to
control the pump speed.
The installation shown in F
IG. 2 is only a guide for
selecting and installing system components and acces-
sories. Contact your Graco distributor for assistance in
designing a system to suit your particular needs.
Mount the pump securely so that it cannot move
around during operation. Failure to do so could result
in personal injury or equipment damage.
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.
