7. Solvent Weld the Tubing
Solvent weld the PVC tubing connections, using care to maintain the established drainage pitch in
the lines. Make sure each union connection includes the required O-ring. Securely hand tighten the
union nuts.
Solvent weld the heater pressure switch into the open tee fitting at this time.
CHECK POINT # 5.
Confirm that:
All previous check point requirements have been met.
The solvent welding is complete and the union nuts, with O-rings in place, have been hand
tightened.
The pressure switch from the heater is solvent welded.
8. Make the Electrical Connections
WARNING: Risk of electric shock.
Make sure the power has been disconnected before performing the
following procedures. Refer to the Important Information at the front of this manual.
WARNING: Risk of electric shock.
Both services must have a Ground-Fault Circuit-Interrupter (GFCI)
or Earth-Leakage Circuit-Breaker (ELCB) which will provide additional protection against
line-to-ground shock hazard.
The controls and systems have been pre-wired at the factory. A licensed electrician should make a
routine service connection to both junction boxes located near the pump. One junction box is for the
pump and control system; the second is for the heater. Both boxes contain blue and brown wires
and an earth lug.
Use a 220-240 V, 20 A, 50/60 Hz dedicated service for the pump and control. Use a second 220-240
V, 20 A, 50/60 Hz dedicated service for the heater.
Provide a separate equipment earthing conductor for the inside earth lug. The earthing conductor
must not
be connected to any current-carrying conductor. Follow local electrical codes.
Connect the 8-gauge solid copper bonding wire (supplied) from the heater to one of the open lugs
found on a junction box.
