INSTALLATION AND MAINTENANCE INSTRUCTIONS 12V DIAPHRAGM PUMPS
Instructions for Assembly, Testing, Operation, Servicing, and Storage
Please read and save these instructions. Read carefully before attempting to assemble, install, operate or maintain this
pump. Protect yourself and others by observing all safety information. Failure to comply with instructions could result in
personal injury and/or property damage! Retain instructions for future reference.
Unpacking - When unpacking, inspect carefully for any damage that may have occurred during transit. Make sure the pump
is correctly installed before putting unit into service.
READ and UNDERSTAND the Owner's Manual completely before using this Pump.
Assemble, test, and use only in accordance with this Owner's Manual instructions.
DO NOT TURN ON POWER to pump until ready to spray in order to avoid unintentional spray release.
Improper use of the pump could result in serious injury to the operator or nearby persons/animals, or could cause damage to
the environment.
Summary of Important Information
Listed below is a summary of safety information of particular importance.
DURING ASSEMBLY
EXERCISE CAUTION when attaching the ON/OFF switch (not included) to battery terminals. Follow the steps listed
in the Assembly section of this manual in exact sequence when connecting the pump to battery terminals. Caution
must be exercised to avoid contact with battery acid and to prevent sparking.
CHECK and TEST completed assembly as directed in this manual.
DO NOT MODIFY pump design
Installation
STEP ONE: Mounting
This pump is self-priming. The pump should be located in an area that is dry and provides ventilation.
DO NOT locate the motor near low temperature plastics or combustible material. The surface temperature of the motor may
exceed 121℃.
The pump may be mounted in any position. However, if mounting the pump vertically the pump head should be in
the down position so that in the unlikely event of a leak, fluid will not enter the motor.
Secure the rubber feet with appropriate fasteners. DO NOT compress the feet, doing so will reduce their ability to
isolate vibration and noise.
STEP TWO: Connect pump to input and output hoses
Sealers and Teflon tape may act as lubricant causing cracked housings or stripped threads due to over tightening. Care should
be used when applying sealers; it may enter the pump inhibiting valve action, causing no prime or no shut-off. Failures due to
foreign debris are not covered under the warranty.

STEP THREE: Connect pump to battery or 12V supply
!
Batteries are hazardous because they contain caustic acid and can emit explosive gases. Caution must be exercised when
making connections to a battery to avoid shock and contact with 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.
The pump should be on a dedicated (individual) circuit, controlled with an ON/OFF switch rated at or above the fuse amp
rating indicated by the pump motor label. For the pump to meet European CE requirements the circuit must be protected
with a slow blow fuse or equivalent circuit breaker. Use 14 AWG wire or larger.
Connect the pump to battery using the following procedure:
1. Disconnect the boat’s battery ground wire.
2. Connect the pump's red wire to the positive (+) terminal of the
battery.
3. Connect the pump's black wire to the negative (-) terminal of the
battery.
4. Reconnect the boat’s battery ground wire
Note: Skip steps (1) and (4) if battery is not in a boat or vehicle.
WARNING: Always connect in this sequence to avoid possible shock.
STEP FOUR: Check and test completed assembly
!
Check assembly to assure the pump is properly assembled and in safe working condition.
Test the system for leaks.
1. If a holding tank is used, fill the tank with water.
2. If the pump is an “on demand” pump, when turned on, the pump will prime itself then turn off once reaching
pressure. When the flow continues, the pump will automatically re-start.
3. Check for leaks throughout the system. If a leak is detected, fix the leak and re-test the system.
Operation/Using the Pump
Pressure switch operation
The pressure switch (on the end of the pump) reacts to outlet pressure and interrupts power at the shut-off pressure
indicated on the pump label. When outlet pressure drops below a predetermined limit, the switch will turn the pump ON and
run until the shut-off pressure is achieved. The shut-off pressure is set to factory calibrated standards.
Note: If the plumbing is restrictive or the flow rate is very slow, the Pump may re-pressurize the outlet faster than the fluid is
being released, causing rapid cycling (ON/OFF within 2 seconds). If the pump is subjected to rapid cycling during normal
operation, or for infrequent period, damage may occur. Applications which exhibit rapid cycling should have restrictions in the
outlet eliminated or minimized.
Discontinue use if clogged or inoperative.
If the pump must be left unattended at any time:
1. Disconnect power to the pump
2. Relieve system pressure

Maintenance or Repair
1. To service the pump, disconnect power to the pump and be sure all system pressure is relieved. Perform repairs.
2. Follow the directions provided in the troubleshooting table to repair the pump.
3. Test after servicing.

Storage
Prepare the pump for end-of-season storage by running RV antifreeze through the system. This will keep internal parts
lubricated, protect against corrosion, and protect from freeze damage.
Pump will be damaged if it freezes with water inside. Protect by following the instructions below:
Preparing for storage
1. Add antifreeze –Pour RV antifreeze into the pump system.
Note: RV antifreeze is non-toxic and biodegradable. DO NOT USE automotive antifreeze.
2. Run pump briefly –Turn on the pump and run the water system until antifreeze is pumped through the system.
Removing from storage
1. Drain –Drain the antifreeze left in the pump system into a suitable container.
2. Flush with water –Fill the pump system with fresh water and run through the system. Operate the pump system
until the system is completely flushed. Be sure to set up containers to capture the antifreeze flush water.
3. Disposal –Dispose of the antifreeze and flush water properly.
