Warning Label Location Part# 793288 Description Pump warning decal Model All Always make sure safety labels are in place and in good condition. If a safety label is missing or not legible, order new labels or unsafe operation could result. To order replacement safety labels, call NorthStar Product Support at 1-800-270-0810.
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. 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]. • 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.
Installation (continued) Step Three: Connect pump to battery or 12V DC 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.
Installation (continued) 3. Connect pump to battery Connect the pump to a 12V DC battery using the following procedure: a) b) c) d) Disconnect the vehicle battery ground wire. Connect the pump’s red wire to the positive (+) terminal of the battery. Connect the pump’s black wire to the negative (-) terminal of the battery. Reconnect the vehicle battery ground wire. Note: Skip steps (a) and (d) if battery is not in a vehicle. WARNING: Always connect in this sequence to avoid possible shock.
Installation (continued) Step Four: Check and test completed assembly. WARNING Check and test completed assembly Serious injury could result from chemical leaks if pump is improperly assembled or the design of the pump is modified. Follow the steps below to ensure the pump is properly assembled. Never modify the pump design. 1. Check assembly Check assembly to assure the pump is properly assembled and in safe working condition. 2.

Operation – Important Safety Information (continued) Chemical accident procedures: WARNING Before you use the pump, review the following information with regard to handling accidents. Chemical spills, pump leaks, personal contamination, and poisoning are accident situations which you may encounter. All require an immediate response – See instructions below. Pump leak In the event that the pump develops a leak while spraying chemicals, you must immediately stop spraying.
Operation – Important Safety Information (continued) Chemical spills Chemical spills must be quickly contained and properly cleaned up. Refer to the chemical label for any specific clean-up instructions with regard to the chemical spilled. General procedures include: 1. Control the spill by stopping the source of the spill. If the source of the spill is a container leak, place the leaking container in a larger, watertight container. Keep unprotected people away from the spill site. 2.
Operation – Preparing the Pump for Each Use If the pump has been used previously, it must be prepared BEFORE EACH SUBSEQUENT USE. WARNING Read instructions below carefully for inspecting and preparing the pump. Damaged or clogged equipment could result in leaks or uncontrolled spray. Leaks could result in injury to the operator or bystanders from chemical exposure, or cause damage to the environment. Important safety rules: • • • Power off.
Operation – Using the Pump Step One: Assess wind conditions and clear work area. Before you decide to spray, you must determine whether wind conditions are suitable. You must also restrict access to the work area to ensure the safety of bystanders. WARNING Do not spray if wind speeds are greater than 5 MPH or if there are bystanders in the intended spray area. 1. Assess wind speed Assess weather conditions to ensure that it is not too windy to spray. DO NOT SPRAY if wind speeds are greater than 5 MPH.
Operation – Using the Pump (continued) 4. Pressure switch operation The pressure switch reacts to outlet pressure, and interrupts power at the preset shut-off pressure indicated on the pump label. When outlet pressure drops below a predetermined limit the switch will close and the pump operates until the shut-off pressure is achieved. The shut-off pressure is set to factory calibrated standards.
Operation – Using the Pump (continued) 7a. Spraying roofs with soft wash mix Follow the steps below for spraying a roof: 1. Using a 3% mix (see table), spray roofs from top to bottom. 2. 7b. Spraying siding with soft wash mix Spray in 10-foot-wide sections, only applying enough to get the surface wet. 3. Let the chemical dwell for approx. 10 minutes, but do not let the chemical dry on the surface. While the chemical is dwelling, the previous section can be rinsed.
Operation – Using the Pump (continued) 8. Rinsing 9. Leaving unattended 10. Discontinue use if clogged or inoperative After spraying, rinse all surfaces and vegetation. 1. Using fresh water from a garden hose, rinse any vegetation that may have come into contact with soft wash mix. 2. Rinse surfaces from top to bottom. Rinse until there are no visible suds on the cleaned surface. To extend the life of the bleach pump system's replaceable pump cartridge: 1. Fill tank with fresh water. 2.
Operation – Using the Pump (continued) Step Three: Clean pump and decontaminate after use. When done using the pump, it is important to clean the pump and decontaminate yourself. Do not store the pump when saturated with chemicals, as it is unsafe and could also result in damage to the equipment. WARNING Cleanup and decontamination procedures must be followed after each use.
Storage When not in use, store the pump indoors. For long term or winter storage, prepare the pump by running RV antifreeze (DO NOT use automotive antifreeze) through the system. This will keep internal parts lubricated, protect against corrosion, and keep the unit from freezing. CAUTION The pump will be damaged if it freezes. Protect the pump from freezing during storage by following the instructions below. Preparing for storage: 1.
Troubleshooting WARNING Before troubleshooting or attempting to service, read the following safety rules to avoid accidental exposure to chemical and also risk of electric shock. Note: A reserve, clean container capable of holding at least the volume of the entire pump system should be kept for use when the pump system needs to be emptied temporarily for repairs. It is advisable to purchase a reserve tank suitable for chemical storage from Northern Tool and Equipment for use in these circumstances.
Troubleshooting (continued) PROBLEM CAUSE SOLUTION Pump will not turn on Bad electrical connection Short in wires Fuse blown Faulty pressure switch Incorrect voltage Check battery connections Check condition of wires Replace fuse Replace pressure switch assembly Check voltage (±10%) Pump will not turn on and LED light is on Leak inside pump cartridge Replace pump cartridge Out of product Refill supply container Tighten fittings Replace cracked fittings Remove restriction Check voltage (±10%) Remov
Maintenance In the event of an internal pump cartridge leak, the pump will shut off to protect the motor and the LED light will turn on to indicate the problem. - Review the instructions in the service section of the manual before servicing. - To repair the pump, use replacement pump cartridge A157145 (for 2.2 GPM pump), A157147 (for 4.0 GPM pump), or A157153 (for 5.5 GPM pump).
