Changing The Orientation Of The Fluid Inlet And Outlet Ports; Fluid Pressure Relief Valve - Graco Husky 2150 Instructions And Parts List

Changing the Orientation of the Fluid Inlet
and Outlet Ports
The pump is shipped with the fluid inlet (R) and outlet
(S) ports facing the same direction. See Fig. 4. To
change the orientation of the inlet and/or outlet port:
1. Remove the screws and washers (106, 112, 113
and 114) holding the inlet (102) and/or outlet (103)
manifold to the covers (101).
2. Reverse the manifold and reattach. Install the
screws and washers and torque to 150- 160 in- lb
(17- 18 N•m). See Torque Sequence, page 33.

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 ambi-
ent 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
