GENERAL

Electric Shock Hazard. Disconnect all power before installing or servicing fan switch. Failure to do so could result in personal injury or property damage. Fan switch must be installed by a quali- fied person in accordance with the National Electrical Code, NFPA 70.

This fan switch kit can be used on all 208, 240 and 277 Volt LUH/KUH heaters with single or 3 phase motors for fan only operation. See Model Number list on page 2. For all 480 Volt

LUH/KUH heaters, the summer fan switch and relay option must be used (see PF481).

INSTALLATION

The kit comes complete with all necessary wiring and mounting screws. A wall box plate is included for remote mount- ing of the selector switch and can be discarded if the switch is to be mounted on the heater.

To install on the heater, open the wiring access door located on the bottom of the heater by turning the captive latching screw 90 degrees in either direction (see Figure 1). The selector switch is to be mounted using the knockout hole on the front of the heater, located right above the Chromalox or Heatflo Label (see

Figure 2). The switch has all of the wiring already connected to the correct terminals and the three leads to be wired to other com- ponents marked by their respective terminal number, these are wire numbers 1, 3 and 9. Before installing the switch, check all the wiring connections to be sure none have gotten loose during shipping and handling.

Mount the switch with the toggle through the hole from inside the wiring compartment. Secure the switch using the on/off plate and hex nut (see Figure 3).
