If the pump motor wiring is disconnected for removal from the unit,
make sure that you check the actual rotation direction
when the motor is rewired to the unit.
A phase sensor does not always indicate proper rotation
if motor wire leads are reversed at installation.
Consult the elementary wiring diagram for more information.
Heaters
Heaters may need to be cleaned chemically or mechanically to remove deposits and
dirt that reduce heat transfer and cause hot spots. Hot spots cause premature heater
failure. Install a new gasket when reassembling. Make sure a qualified electrician
disconnects and reconnects heater wires.
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.
6-3 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
