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.

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
1.
2.
3.
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.

Maintenance
Lubrication
The air valve is lubricated at the factory to operate
without additional lubrication. If you want to provide
additional lubrication, remove the hose from the pump
air inlet and add two drops of machine oil to the air inlet
every 500 hours of operation or every month.
Flusing and Storage
Flush the pump to prevent the fluid you are pumping
from drying or freezing in the pump and damaging it.
Use a compatible solvent.
Always flush the pump and relieve the pressure before
you store it for any length of time.
Tightening Threaded Connections
Before each use, check all hoses for wear or damage and
replace as necessary. Check to be sure all threaded
connections are tight and leak-free. Check fasteners.
Tighten or retorque as necessary.
Although pump use varies, a general guideline is to
retorque fasteners every two months. See Torque
Sequence on page 20.
Preventative Maintenance Schedule
Establish a preventive maintenance schedule, based on
the pump’s service history. This is especially important
for prevention of spills or leakage due to diaphragm
failure.
CAUTION
Do not over-lubricate the pump. Oil is exhausted through
the muffler, which could contaminate your fluid supply or
other equipment. Excessive lubrication can also cause
the pump to malfunction.
