NOTE: Before installing disconnect switch, check heater data label
to ensure that heater electrical rating does not exceed the switch
electrical rating.
NOTE: All wiring must be done in accordance with National and
Local Electrical Codes. Supply conductors to unit must be copper.
1.) Disconnect heater from power supply.
2.) Locate and remove large knockout and two adjacent small
knockouts from heater where switch is to be mounted.

ground lead to the grounding screw (or lug). On some models
with adequate access the switch may be mounted (Step 5)
prior to connecting the supply wiring.
5.) Place the switch inside the heater control compartment with
the shaft extending through the 1/2” diameter knockout. The
