DRIVE CONFIGURATION

Operation Testing

Operation Testing
Risk of bodily injury or damage to pump or other equipment.
• Never operate the pump with isolation valve closed.
IMPORTANT: For the pump to operate properly as it boosts water to the desired pressure, a consistent
and steady flow of water is required. The system will fail prematurely if it is set to operate at a point
beyond what can be supplied.
1. Close the shut-off valve near the discharge.
IMPORTANT: Make sure the supply water is allowed to freely flow into the pump without restriction.
2. Adjust system for maximum flow demand.
3. Turn on the pump.
4. Begin opening the shut-off valve.
5. Continue opening the discharge valve until cavitation is heard coming from the pump.
• Cavitation can destroy the pump over time and will sound like there is gravel inside the pump.
• Stop opening the discharge valve once cavitation is heard.
6. Slowly close the discharge valve until the cavitation is no longer heard.
NOTE: The pump is now adjusted so that the system demand will not exceed what can be supplied. If
the supply pressure or water demand varies over time, this procedure may need to be repeated to elim-
inate cavitation.
DRIVE CONFIGURATION
Risk of severe injury or death by electrical shock.
• Serious or fatal electrical shock may result from contact with internal electrical components. Do not,
under any circumstances, attempt to modify DIP switch settings until power has been removed and
5 minutes have passed for internal voltages to discharge. Power must be removed for DIP switch
setting to take effect.

Adjusting System Pressure

The pressure sensor communicates the pressure to the system. The sensor is factory set to 50 psi
(3.4 bar), but can be adjusted by performing the following:
1. Remove the rubber end cap.
2. Using a 7/32" Allen wrench (provided), turn the screw to adjust pressure
• Turn clockwise to increase pressure.
• Turn counter-clockwise to decrease pressure.
• The adjustment range is between 25 and 80 psi (1.7 and 5.5 bar).
• turn = approximately 3 psi (0.2 bar).

3. Replace the rubber end cap.
4. Cover the pressure sensor terminals with the rubber boot provided.
