Installation

63A3383D

Installation

Grounding

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.

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 immedi-

ately.

Air compressor: follow manufacturer’s recommenda-

tions.

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.

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 non-conductive sur-

face, 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 or

valve firmly to the side of a grounded metal pail, then

trigger the gun or open the valve.

The equipment must be grounded to reduce the risk

of static sparking. Static sparking can cause fumes to

ignite or explode. Grounding provides an escape wire

for the electric current.

Mounting

Stand Mount

Order Part No. 253692 Pump Stand Kit (accessory).

Mount the pump in the pump stand and secure with the

four screws and lock washers supplied in the kit.

See Mounting Hole Layouts on page 18. 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.

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 connection 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 18.

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.

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 con-

taminating your fluid with oil, flush the equipment with a

compatible solvent before using the equipment. See

Flushing, page 11.

Installation

83A3383D

Accessories

Install the following accessories in the order shown in

FIG. 2, using adapters as necessary.

Air Line

•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.

•Pump air regulator (L): to control pump speed and

outlet pressure. Locate close to the pump.

•Air line filter (K): removes harmful dirt and mois-

ture 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.

Trapped air can cause the pump to cycle unexpect-

edly, which could result in serious injury from splash-

ing 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 over pressurization, 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.

Operation

Pressure Relief Procedure

Follow the Pressure Relief Procedure when-

ever you see this symbol.

1. Close the bleed-type master air valve (M).

2. Open the dispensing valve, if used.

3. Open all fluid drain valves (N) in the system, having

a waste container ready to catch drainage. Leave

drain valve(s) open until you are ready to pump

again.

Prime the Pump

1. Fill the wet cup with Throat Seal Liquid (TSL).

NOTE: Sealed 4 ball lowers with bellows do not require

TSL.

NOTE: During operation the TSL level in the wet cup will

fluctuate slightly at pump changeover.

2. Close pump air regulator (L) by turning knob coun-

terclockwise reducing pressure to zero. Close

bleed-type air valve (M). Also verify that all drain

valves (N) are closed.

3. Connect air line (J) to bleed type air valve (M).

4. Check that all fittings throughout system are tight-

ened securely.

5. Connect the fluid supply line (C) from the mix tank

shutoff valve (D) to the pump.

6. Connect the fluid line (E) to the pump outlet.

7. Open bleed-type air valve (M). Slowly turn pump air

regulator (L) clockwise, increasing pressure until

pump starts.

8. Cycle pump slowly until all air is pushed out and

pump and hoses are fully primed.

9. Close the fluid shutoff valve (D) downstream of the

pump. The pump should stall against pressure.

NOTE: In a circulation system, the pump operates con-

tinuously until the power supply is shut off. In a

direct-supply system, the pump starts when the dis-

pense valve is opened, and stops when the dispense

valve is closed.

Stop Pump at Bottom of Stroke

Relieve the pressure when you stop the pump for any

reason. Stop the pump on the down stroke, before the

air motor changes over.

Shutdown

Follow the Pressure Relief Procedure, page 10.

Always flush the pump before the fluid dries on the dis-

placement rod. See Flushing on page 11.

This equipment stays pressurized until pressure is

manually relieved. To help prevent serious injury from

splashing fluid and moving parts, follow the Pressure

Relief Procedure when you stop spraying and before

cleaning, checking, or servicing the equipment.

NOTICE

Failure to stop the pump at the bottom of its stroke

allows fluid to dry on the piston rod, which can dam-

age the throat seal.
