Installation
Changing the Orientation of the Fluid Inlet
and Outlet Ports
You can rotate the fluid inlet and outlet manifolds (102)
to three positions. As shipped, the fluid inlet manifold
points down and the fluid outlet manifold points toward
from the air valve (A). See Fig. 6.
1.
Remove the four nuts (105) and bolts (104) from
each end of the manifold (102).
2.
Turn the manifold to the desired position, and
reinstall the bolts and nuts. Torque to 20 to 25 in-lb
(2.3 to 2.8 N-m).
NOTE: If the manifold is difficult to rotate, loosen the
nuts (114) holding the clamps (113). After turning the
manifold, torque the nuts to 75 to 85 in-lb (8.5 to
9.6 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. 7.
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.
