CAUTION

Disconnect power supply before beginning installation

Location

1. Locate the high limit bulb in the hot water outlet header

of the heater. Locate the pool control bulb in the return
water header of the heater.

2. Uncoil no more tubing than needed. Sharp or repeated

bending of the tubing can cause damage.

3. If the tubing is subjected to vibration, protect it against

wear when it comes in contact with another surface.

Mounting

1. Remove the cover by loosening the cover screw on the

lower front of the controller.

2. Fasten the case to a convenient wall or panel with

screws through the three mounting holes in the back of
the case.

3. Replace cover.
