OVERLOAD RELAY
The overload relay protects the standby electric motor. It is located in the control box under the high voltage cover. The
overload relay opens the circuit to the electric motor if the current exceeds the overload relay setting. The overload relay resets
automatically.

Overload Relay Replacement
When the overload relay is replaced, the new overload relay must be set up to open at the correct amperage and reset
automatically. See the following procedure to set up a new overload relay.
1. Open the clear plastic cover.
2. Use a small screwdriver to set the opening amperage. See “Electric Motor and Overload Relay” in the “Specifications”
chapter for the correct overload relay setting.
3. Use a small screwdriver to remove the tab marked with an “H” to access the switch used to set the overload relay to reset
automatically.
