Installation

Step One: Mounting
•
This NorthStar pump is self-priming.
•
The pump should be located in an area that is dry and provides adequate ventilation.
•
The pump may be mounted in any horizontal position.
DO NOT
mount pump vertically, doing so
will prevent the Motor Armor system from operating correctly.
•
Secure the rubber base with #10 fasteners.
DO NOT
compress the base, as doing so will reduce
the ability to isolate vibration and noise. Note: Fasteners are not included.
Step Two: Plumbing
•
See table below for port size and recommended hose sizes.
o
Remove shipping plugs from pump ports.
o
Use NorthStar quick connect fittings to connect flexible high-pressure tubing to the quick
connect ported pumps.
o
To insert quick connect fittings, lubricate O-ring with water and twist fitting while inserting
into pump port.

•
Tubing should be compatible with the spraying fluid. At least 18" [450mm] length is suggested to
minimize stress on the fitting/ports and reduce noise. Allow for the shortest possible tubing route
and avoid sharp bends that may kink over time.
•
Installation of a 50-mesh strainer is recommended to prevent foreign debris from entering the
system. Failures due to foreign debris are not covered under the warranty.
NOTE:
Restrictions on the inlet may cause a loss in performance. Inlet pressure must not exceed 30 psi [2.1
bar]
•
If a check valve is installed in the plumbing, it must have a cracking pressure of no more than 2
psi [.14 bar].
CAUTION
DO NOT
locate the motor near low temperature plastics or combustible material. The surface
temperature of the motor may exceed 250°F [121
°
C].
