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. Model 241906 is shipped with
the fluid inlet manifold pointing toward the air inlet and the
fluid outlet manifold pointing away from the air inlet. See
Fig. 4.
1. Remove the bolts (105) holding the manifold (102) to
the covers (101). Save the attaching hardware.
2. Turn the manifold to the desired position, and reinstall
the hardware. Torque the bolts (105) to 80 to 90 in–lb
(9 to 10 N•m). See Torque Sequence, page 22.

Fluid Pressure Relief Valve
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. 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 238428 is available for use on
aluminum Husky 716 pumps and may be purchased
separately.
