Assembly Step 1 – Regulator Installation Tools Needed • Install the regulator into either outlet port at the top of the pump manifold. o Use flat blade screwdriver to remove QC clip from the pump before installing fitting. Snap QC clip back into pump after fitting is inserted. Note: The pump is configured for installing the regulator in the right side of the manifold. If the left side preferred, the QC plug must first be moved from the left side outlet port to the right side outlet port.
Assembly Step 2 – Inlet and Outlet Fitting Installation Tools Needed • Install either the QC x 1/2 HB fitting or QC x ½ MNPT fitting into either inlet port at the bottom of the pump manifold. o Use a flat blade screwdriver to remove QC clip from the pump before installing fitting. Snap QC clip back into pump after fitting is inserted. Note: The pump is configured for installing the inlet fitting in the left side of the manifold.
Assembly Step 3 – Connect Inlet, Outlet, and Bypass Hoses Tools Needed • Use the provided hose clamp and connect a ¾” flexible hose (not provided) to the regulator’s bypass port. The hose should return to the pump’s water supply. See the Operation section of the manual for detailed information about the regulator’s bypass function. • Connect appropriate flexible hoses to the pump’s inlet and outlet ports. See the Installation section of the manual for more detailed plumbing requirements.
Installation Step One: Mounting • This NorthStar pump performs best with a flooded inlet. (The pump’s inlet should be located below the supply water level.) If the pump must be placed above the water supply, suction lift is not to exceed two feet (0.6m). CAUTION NEVER operate the pump dry. Catastrophic failure will occur. All plunger pumps require liquid to lubricate the seals and keep them from overheating. • The pump should be located in an area that is dry and provides adequate ventilation.
Installation (continued) Step Three: Connect pump to battery or 12V supply WARNING Batteries are hazardous because they contain caustic acid, can emit explosive gases, and can cause electric shock. Caution must be exercised when making connections to a battery to avoid shock and contact with the acid, and to prevent any sparking that could lead to an explosion. ALWAYS follow the safety instructions and steps listed below in exact sequence when connecting the pump to the battery terminals. 1.
