planning a system to suit your needs.

• Always use Genuine Graco Parts and Accessories.

• Use a compatible, liquid thread sealant on all male

threads. Tighten all connections firmly to avoid air or

fluid leaks.

Tightening Threaded Fasteners Before First

Use

Before using the pump for the first time, check and

retorque all external fasteners. See Torque Sequence

on page 20. After the first day of operation, retorque the

fasteners. Although pump use varies, a general

guideline is to retorque fasteners every two months.

Toxic Fluid Hazard

Use fluids and solvents that are compatible with the

equipment wetted parts. Refer to the Technical Data

section of all equipment manuals. Read the fluid and

solvent manufacturer’s warnings.

Mountings

• Be sure the mounting surface can support the

weight of the pump, hoses, and accessories, as well

as the stress caused during operation.

• Fig. 2 shows a typical installation. Mount the pump

using screws and nuts.

• Prolonged exposure to UV radiation will degrade

natural polypropylene components of the pumps. To

prevent potential injury or equipment damage, do

not expose pump or the plastic components to direct

sunlight for prolonged periods.

CAUTION

Safe Operating Temperatures

Minimum: 40°F (4°C)

Maximum: 180° F (82°C)

These temperatures are based upon mechanical stress only

Installation

Air Line

1. Install the air line accessories as shown in Fig. 2.

Mount these accessories on the wall or on a

bracket. Be sure the air line supplying the

accessories is electrically conductive.

a. The fluid pressure can be controlled by installing

an air regulator (G).

b. Locate one bleed-type master air valve (B) close

to the pump and use it to relieve trapped air.

Read the WARNING above. Locate the other

master air valves upstream from all air line

accessories and use it to isolate them during

cleaning and repair.

c. The air line filter (F) removes harmful dirt and

moisture from the compressed air supply.

2. Install an electrically conductive, flexible air hose (C)

between the accessories and the 1/4 npt(f) pump air

inlet. Use a minimum 1/4” (6.3 mm) ID air hose.

Screw an air line quick disconnect coupler (D) onto

the end of the air hose (C), and screw the mating

fitting into the pump air inlet snugly. Do not connect

the coupler (D) to the fitting yet.

Fluid Suction Line

• If using a conductive (acetal) pump, use conductive

hoses. If using a non-conductive pump, ground the

fluid system. Read Grounding on page 8. The fluid

inlet ports are 3/4 in.

• At inlet fluid pressures greater than 15 psi (0.1 MPa,

1 bar), diaphragm life will be shortened.

1. Use electrically conductive fluid hoses (K). The

pump fluid outlet is 1/2 in. or 3/4 in. Screw the fluid

fitting into the pump outlet snugly. Do not

overtighten.

2. The fluid pressure can be controlled by installing an

air regulator (G).

3. Install a fluid drain valve (H) near the fluid outlet.

Read the WARNING above.

WARNING

A bleed-type master air valve (B) is required in your

system to relieve air trapped between this valve and the

pump. See Fig. 2. Trapped air can cause the pump to

cycle unexpectedly, which could result in serious injury,

including splashing in the eyes or on the skin, injury from

moving parts, or contamination from hazardous fluids.

CAUTION

The pump exhaust air may contain contaminants.

Ventilate to a remote area if the contaminants could

affect your fluid supply. Read Air Exhaust Ventilation

on page 6. WARNING

A fluid drain valve (H) is required in your system to

relieve pressure in the hose if it is plugged. See Fig. 2.

The drain valve reduces the risk of serious injury,

including splashing in the eyes or on the skin, or

contamination from hazardous fluids when relieving

pressure. Install the valve close to the pump fluid outlet.

Installation

Fluid Pressure Relief Valve Air Exhaust Ventilation

The air exhaust port is 3/8 npt(f). Do not restrict the air

exhaust port. Excessive exhaust restriction can cause

erratic pump operation.

See Venting Exhaust Air in Fig. 2. Exhaust to a remote

location as follows:

1. Remove the muffler (W) from the pump air exhaust

port.

2. Install an electrically conductive air exhaust hose

(X) and connect the muffler to the other end of the

hose. The minimum size for the air exhaust hose is

3/8 in. (10 mm) ID. If a hose longer than 15 ft (4.57

m) is required, use a larger diameter hose. Avoid

sharp bends or kinks in the hose.

3. Place a container (Z) at the end of the air exhaust

line to catch fluid in case a diaphragm ruptures. See

Fig. 2.

CAUTION

Some systems may require installation of a pressure

relief valve at the pump outlet to prevent

overpressurization and rupture of the pump or hose.

See Fig. 1. Thermal expansion of fluid in the outlet

line can cause overpressurization. This can occur

when using long fluid lines exposed to sunlight or

ambient heat, or when pumping from a cool to a warm

area (for example, from an underground tank).

Overpressurization can also occur if the Husky pump

is being used to feed fluid to a piston pump, and the

intake valve of the piston pump does not close,

causing fluid to back up in the outlet line.

Install valve between fluid inlet and outlet ports.

Connect fluid inlet line here.

Connect fluid outlet line here.

Be sure the system is properly ventilated for your type

of installation. You must vent the exhaust to a safe

place, away from people, animals, food handling

areas, and all sources of ignition when pumping

flammable or hazardous fluids. Diaphragm failure will

cause the fluid being pumped to exhaust with the air.

Place an appropriate container at the end of the air

exhaust line to catch the fluid. See Fig. 2 .

Installation

Grounding

To reduce the risk of static sparking, ground the pump

and all other equipment used or located in the pumping

area. Check your local electrical code for detailed

grounding instructions for your area and type of

equipment.

NOTE: When pumping conductive flammable fluids,

always ground the fluid system. See the WARNING

above. Fig. 3 shows a recommended method of grounding

flammable fluid containers during filling.

Ground all of this equipment:

•Pump: The acetal pump has a grounding screw on

the top manifold. Connect the non-clamp end of the

ground wire to the grounding strip or grounding

screw, and connect the clamp end of the ground

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 the manufacturer’s

recommendations.

•Solvent pails used when flushing: Follow the local

code. Use only grounded metal pails, which are

conductive. Do not place the pail on a non-

conductive surface, such as paper or cardboard,

which interrupts the grounding continuity.

•Fluid supply container: Follow the local code.

WARNING

The acetal Husky 515 pump contains stainless steel

fibers, which makes the wetted parts conductive.

Attaching the ground wire to the grounding screw

(106) grounds the wetted parts. See grounding

screw on page 18.

When pumping conductive flammable fluids, always

ground the entire fluid system by making sure the fluid

system has an electrical path to a true earth ground

(see Fig. 3). Never use a polypropylene or PVDF

pump with non-conductive flammable fluids as

specified by your local fire protection code.

US Code (NFPA 77 Static Electricity) recommends a

conductivity greater than 50 x 10 -12 Siemans/meter

(mhos/meter) over your operating temperature range

to reduce the hazard of fire. Consult your fluid supplier

to determine the conductivity or resistivity of your fluid.

The resistivity must be less than 2 x 1012 ohm-

centimeters.

Operation

Pressure Relief Procedure

1. Shut off the air to the pump.

2. Open the dispensing valve, if used.

3. Open the fluid drain valve to relieve all fluid

pressure, and have a container ready to catch the

drainage.

Flush Pump Before First Use

The pump was tested in water. If water could

contaminate the fluid you are pumping, flush the pump

thoroughly with a compatible solvent. Follow the steps

under Starting and Adjusting Pump.

Starting and Adjusting Pump

4. Check all fittings to be sure they are tight. Use a

compatible liquid thread sealant on all male threads.

Tighten the fluid inlet and outlet fittings snugly. Do

not overtighten the fittings into the pump.

5. Place the suction tube (if used) in the fluid to be

pumped.

NOTE: If the inlet fluid pressure to the pump is more

than 25% of the outlet working pressure, the ball check

valves will not close fast enough, resulting in inefficient

pump operation.

6. Close the fluid drain valve (H).

7. With the pump air regulator (G) closed, open all

bleed-type master air valves (B).

8. If the fluid hose has a dispensing device, hold it open

while continuing with the following step. Slowly open

the air regulator (G) until the pump starts to cycle.

Allow the pump to cycle slowly until all air is pushed

out of the lines and the pump is primed.

If you are flushing, run the pump long enough to

thoroughly clean the pump and hoses. Close the air

regulator. Remove the suction tube from the solvent

and place it in the fluid to be pumped.

WARNING

PRESSURIZED EQUIPMENT HAZARD

The equipment stays pressurized until pressure is

manually relieved. To reduce the risk of serious injury

from pressurized fluid, accidental spray, or splashing

fluid, follow this procedure whenever you:

• Are instructed to relieve pressure

• Stop pumping

• Check, clean, or service any system equipment

• Install or clean fluid nozzles

Read Toxic Fluid Hazard

on page 3.

If lifting the pump, follow the

Pressure Relief Procedure above.

Be sure the pump is

properly grounded.
