WARNINGWARNING

SKIN INJECTION HAZARD

Fluid from the dispensing valve, leaks or ruptured components can inject fluid into your body and
cause extremely serious injury, including the need for amputation. Fluid splashed in the eyes or on
the skin can also cause serious injury.

D Fluid injected into the skin may look like just a cut, but it is a serious injury. Get immediate

surgical treatment.

D Do not point the dispensing valve at anyone or at any part of the body.

D Do not put your hand or fingers over the end of the dispensing valve.

D Do not stop or deflect leaks with your hand, body, glove or rag.

D Use only extensions and no-drip tips which are designed for use with your dispensing valve.

D Tighten all fluid connections before operating the equipment.

D Check the hoses, tubes, and couplings daily. Replace worn or damaged parts immediately. Do

not repair high pressure couplings; you must replace the entire hose.

HAZARDOUS FLUIDS

Improper handling of hazardous fluids or inhaling toxic fumes can cause extremely serious injury,
even death, due to splashing in the eyes, ingestion, or bodily contamination.

D Know the specific hazards of the fluid you are using.

D Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,

state and national guidelines.

D Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid

and solvent manufacturer.

WARNINGWARNING

FIRE AND EXPLOSION HAZARD

Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and
result in a fire or explosion and serious injury.

D Ground the equipment. Refer to Grounding on page 7.

D If there is any static sparking or you feel an electric shock while using this equipment, stop

dispensing immediately. Do not use the equipment until you identify and correct the problem.

D Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid

being dispensed.

D Do not smoke in the dispensing area.

MOVING PARTS HAZARD

Moving parts can pinch or amputate your fingers.

D Keep clear of all moving parts when starting or operating the pump.

D Before servicing the equipment, follow the Pressure Relief Procedure on page 8 to prevent the

equipment from starting unexpectedly.

Installation

System Accessories

CAUTION

Do not hang the air accessories directly on the air
inlet (E). The fittings are not strong enough to
support the accessories and may cause one or
more to break. Provide a bracket on which to
mount the accessories.

NOTE: Install the accessories in the order shown in

Fig. 1.

WARNING

Four accessories are required in your system: an
air shut-off valve/air bleed device, fluid drain valve,
thermal relief kit, and ground wire. These accesso­ries help reduce the risk of serious bodily injury
including fluid injection, splashing in the eyes or on
the skin, injury from moving parts if you are adjust­ing or repairing the pump, and explosion from
static sparking.

The air bleed device relieves air trapped between it
and the air motor after the air supply is shut off.
Trapped air can cause the air motor to cycle unex­pectedly, causing serious bodily injury if you are
adjusting or repairing the pump. Use either a
bleed-type master air valve (A) or a quick-discon­nect coupler (M) and fitting (L). Install near the
pump air inlet, within easy reach of the pump.

1. Screw the muffler (5) into the 3/4-in. npt muffler
port, and tighten it using a wrench on the flats of
the muffler near the male threads.

2. Install an air line lubricator (N) for automatic air
motor lubrication.

3. Install the air regulator (C) to control pump speed
and pressure.

4. Install an air line filter (B) to remove harmful dirt
and contaminants from your compressed air
supply.

5. Install a bleed-type master air valve (A) to isolate
the accessories for servicing. See Fig. 1. To

order a bleed-type master air valve, order Part No.

107142.

As an alternative to a bleed-type master air valve,
you can install an air line quick disconnect coupler
(M) and fitting (L) to serve as an air-bleed device.
See Detail A in Fig. 1.

6. Install a drain valve (H) near the pump fluid outlet
to relieve fluid pressure in the hoses and gun when
opened. To order a fluid drain valve, order Part

No. 210658.

7. Install a thermal relief kit (K) on the dispensing
valve side of the pump. To order a 1600 psi

(110 bar, 11 MPa) thermal relief kit, order Part No.

240429.

The fluid drain valve (H) assists in relieving fluid
pressure in the displacement pump, hoses and
dispensing valve. Triggering the valve to relieve
pressure may not be sufficient.

The thermal relief kit assists in relieving pressure in
the pump, hose, and dispensing valve due to heat
expansion.

The ground wire reduces the risk of static sparking.

8. Install a suitable fluid hose (P) and dispensing
valve (J).

Cover Mount

For cover mounting, see the Mounting Hole Layout
on page 18.

Wall Mount

The pump shown in Fig. 1 is wall mounted. To order
the wall-mounting bracket, order Part No. 238245.
