Note: Installation and maintenance must be
performed only by qualified personnel who are

Standard Electrical Connection
Each chassis comes with a junction box mounted on the
side of the chassis and contains the field electrical
connection (Figure 10).
Figure 10. Junction Box Location
Note: If electrical wiring or conduit comes through
the oor, all wires or conduit should be sealed at
this point. It will prevent any condensation or water
leakage that may occur due to lack of preventive
maintenance. Each unit has an internal condensate
trap but will require cleaning.
Note: Wiring coming through the wall should be
sealed to stop cold air inltration through the wall
cavity which could affect unit thermostat operation.
Remove the junction box cover, selecting the proper
knockout and remove it. Install a strain relief and pass
the wires through the strain relief into the junction
box making the connection and reinstall the junction
box cover.
Note: Check the local code concerning correct
electrical connection.
