Installing Auxiliary Relays

There can be a maximum of three standard auxiliary relays installed in the SunTouch Power Center.
Depending on the SunTouch kit, relays may not be included in the kit. Relays must be installed at the site.
When using a 2-Speed pump, the optional 2-Speed relay (P/N 520198) can be installed, replacing the standard
relay which is located in the right-side of the Power Center. For more information about SunTouch kits, see
page 38. All SunTouch high voltage double pole relays and are rated at 3HP/30A at 240 VAC (1½ HP/30A at
120 VAC).

Relay locations

A standard relay can be installed in any one of the thee locations provided in the SunTouch Power Center with
the exception of the an optional 2-Speed relay, which can only be installed in the right-side compartment of the
Power Center. Power Center relay locations are shown below.

relay compartment at about a 30 degree angle. Slide the tip of
the relay flange under head of the left-side screw. Rotate the
relay upward to align the right-side flange with the screw hole.
Using a 1/4 in nut driver, secure the relay in place with the
retaining screw.
Standard relay (Location 2): Position the relay (coil facing
upward) in the relay compartment at about a 30 degree angle.
Slide the tip of relay flange under head of the left-side screw.
Rotate the relay downward to align the right-side flange with
