Air Line
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 contamina -
tion from hazardous fluids.
CAUTION
The pump exhaust air may contain contaminants.
V entilate to a remote area if the contaminants could
af fect your fluid supply . See Air Exhaust V entilation
on page 9.
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 acces -
sories is electrically conductive.
a. The fluid pressure can be controlled in either
of two ways. T o control it on the air side, install
an air regulator (G). T o control it on the fluid
side, install a fluid regulator (J) near the pump
fluid outlet (see Fig. 2).
b. Locate one bleed-type master air valve (B)
close to the pump and use it to relieve trapped
air . See the WARNING above. Locate the
other master air valve (E) 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
DUse electrically conductive fluid hoses. The pump
fluid inlet is 3/4 npt(f). Screw the fluid fitting into the
pump inlet snugly
.
D
If the inlet pressure to the pump is more than 25%
of the outlet working pressure, the ball check valves
will not close fast enough, resulting in inef ficient
pump operation.
D At inlet fluid pressures greater than 15 psi (100
kPa, 1.0 bar), diaphragm life will be shortened.
D See the T echnical Data on page 33 for maximum
suction lift and flow rate loss at various lift dis -
tances.
Fluid Outlet Line
WARNING
A fluid drain valve (H) is required in your system to
relieve pressure in the hose if it is plugged. See
Figs. 2 and 3. 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.
1. Use electrically conductive fluid hoses (K). The
pump fluid outlet is 3/4 npt(f). Screw the fluid fitting
into the pump outlet snugly
. Do not overtighten.
2.
Install a fluid regulator (J) at the pump fluid outlet
to control fluid pressure, if desired (see Fig. 2).
See Air Line, step 1a, for another method of
controlling pressure.
3. Install a fluid drain valve (H) near the fluid outlet.
See the WARNING above.

Installation
Changing the Orientation of the Fluid Inlet
and Outlet Ports
You can change the direction of the fluid inlet and
outlet manifolds (102), if desired. As shipped, the fluid
inlet manifold points away from the air valve (A) and
the fluid outlet manifold points toward the air valve.
See Fig. 4.
1. Remove the bolts (105) holding the manifold (102)
to the covers (101). Save the attaching hardware.
2. T urn the manifold to the desired position, and
reinstall the hardware. T orque the bolts (105) to
3–6 ft-lb (4–8 N.m).

Fluid Pressure Relief Valve
CAUTION
Some systems may require installation of a pressure
relief valve at the pump outlet to prevent overpres -
surization and rupture of the pump or hose. See Fig.
5.
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.
Pressure Relief Kit 238–428 is available for use on
aluminum Husky 715 pumps and may be purchased
separately.

Air Exhaust Ventilation
WARNING
FIRE AND EXPLOSION HAZARD
Be sure to read FIRE OR EXPLOSION
HAZARD and T OXIC FLUID HAZARD
on page 3, before operating this pump.
Be sure the system is properly ventilated
for your type of installation. Y ou must
vent the exhaust to a safe place, away from peo -
ple, 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 appropri -
ate container at the end of the air exhaust line to
catch the fluid. See Fig. 6.
The air exhaust port is 3/8 npt(f). Do not restrict the air
exhaust port. Excessive exhaust restriction can cause
erratic pump operation.
T o exhaust to a remote location:
1. Remove the muf fler (W) from the pump air exhaust
port.
2.
Install an electrically conductive air exhaust hose
(X) and connect the muf fler 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.
A void 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.
