Installation
Grounding
The equipment must be grounded. Grounding
reduces the risk of static and electric shock by
providing an escape wire for the electrical current
due to static build up or in the event of a short circuit.
Pump: use a ground wire and clamp (Y). See FIG. 1.
Loosen the grounding lug locknut (W) and washer.
Insert one end of the ground wire into the slot in the lug
and tighten the locknut securely. Connect the ground
clamp to a true earth ground. Order Part No. 237569,
Ground Wire and Clamp.
Object being sprayed: follow local code.
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
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray gun
firmly to the side of a grounded metal pail, then trigger
the gun.
Stand Mount
Order Part No. 253692 Pump Stand Kit (accessory).
Mount the pump in the pump stand and secure with the
four screws and lockwashers supplied in the kit.
See Mounting Hole Layouts on page 17. Secure the
stand to the floor with M19 (5/8 in.) bolts which engage
at least 152 mm (6 in.) into the concrete floor to prevent
the pump from tipping.
F
IG. 1. Ground Wire
Air and fluid hoses: use only electrically conductive
hoses with a maximum of 500 ft. (150 m) combined
hose length to ensure grounding continuity. Check the
electrical resistance of hoses. If total resistance to
ground exceeds 25 megohms, replace hose immediately.
Air compressor: follow manufacturer’s recommendations.
Surge tank: use a ground wire and clamp.
Dispense valve: ground through a connection to a
properly grounded fluid hose and pump.
Fluid supply container: follow local code.
Wall Mount
Order Part No. 255143 Wall Bracket Kit (accessory).
1. Ensure the wall is strong enough to support the
weight of the pump assembly and accessories, fluid,
hoses, and stress caused during pump operation.
2. Ensure that the mounting location has sufficient
clearance for easy operator access.
3. Position the wall bracket at a convenient height,
ensuring that there is sufficient clearance for the
fluid suction line and for servicing the lower.
4. Drill four 7/16 in. (11 mm) holes using the bracket as
a template. Use either of the two mounting hole
groupings in the bracket. See Mounting Hole Lay-
outs, page 17.
5. Bolt the bracket securely to the wall using bolts and
washers designed to hold in the wall’s construction.
6. Attach the pump assembly to the mounting bracket.
7. Connect air and fluid hoses.

Installation
Plumbing
See FIG. 2. Install a fluid shutoff valve (D) between the
mix tank (A) and the pump.
When using a stainless steel pump, use stainless steel
plumbing to maintain a corrosion-resistant system.
Flush Before Using Equipment
The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid contaminating your fluid with oil, flush the equipment with a
compatible solvent before using the equipment. See
Flushing, page 9.
Accessories
Install the following accessories in the order shown in
F
IG. 2, using adapters as necessary.
Air Line
• Pump air regulator (L): to control pump speed and
outlet pressure. Locate close to the pump.
• Air line filter (K): removes harmful dirt and moisture from compressed air supply.
• Second bleed-type air valve (H): isolates air line
accessories for servicing. Locate upstream from all
other air line accessories.
Fluid Line
• Fluid filter: with a 60 mesh (250 micron) stainless
steel element to filter particles from the fluid as it
leaves the pump.
• Fluid drain valve (N): required in your system, to
relieve fluid pressure in the hose and gun.
• Fluid shutoff valve (D): shuts off fluid flow.
• Bleed-type master air valve (M): required in your
system to relieve air trapped between it and the air
motor when the valve is closed.
Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts. Be sure the valve is easily
accessible from the pump and located downstream
from the air regulator. Be sure the air bleed hole
points away from the operator.
To help prevent fluid overpressurization, do not
exceed the maximum air inlet pressure rating to the
air motor (see page 2). If you can apply more than
the maximum air input pressure to the system, install
a safety relief valve between the bleed-type master
air valve and the air motor. The safety relief valve
must be set to open if the air inlet pressure to the
motor exceeds the motor rating.
