Solenoid Valves
Clean annually, more often if using high mineral content water or on high
service level units.
Sluggish operation, excessive leakage, and/or noise indicate cleaning is
necessary. Inspect the components for excessive wear while the valve is
disassembled.
Rebuild kits are available from the ACS Group Parts Department.
Electrical Connections
Make sure that a qualified electrician inspects all electrical components and connections
every six (6) months for secure attachment and ground connections. Inspect all wiring for
fraying or damage, especially power lines where they enter the unit. All wiring connections
must be tight.

Safety Devices
Make sure that only qualified electricians test safety devices!
Safety devices should be tested for function every six (6) months. Perform the following
procedures for testing:
Motor Overload
Disconnect main power. Open the electrical enclosure and rotate the manual TEST button
on the motor overload to the tripped position. Close the enclosure and reconnect main
power. Push the START button. The unit should not start and the Pump Overload indicator
should illuminate.
Press the RESET button. The unit is now ready for operation.
Pressure Switch
With the unit running, program a set point of 32°F (-1°C). Allow the process temperature to
drop under 100°F (38°C). When the process temperature reaches that point, turn off the
water supply. The pump should stop and the Low Water Pressure indicator should
illuminate. Turn the water supply on to reset the pressure switch.
