How To Replace The Spa Pack

When replacing a SC-CF or SC-MP spa pack, it is important to make 
sure to turn power off before proceeding.

9• Slide the pack out of the heater

barrel.

10• Check if high-limit sensor is

properly in place in its slot and
slide new pack into position.

11• Connect heater to the board

blades. It is important to hold
both nuts when tightening. If
you bend or twist the end of
the element, you may damage
it.

12• Reconnect heater ground

cable and pressure switch
cables.

13• Reconnect light cables, keypad

and temperature probe.

14• Plug in Pump 1, Pump 2 (or

blower) and ozonator con-
nectors.

15• Reconnect power input

cables.

16• Close pack cover.
