ELECTRICAL
All wiring must be in compliance with national and local codes. Use copper conductors of the proper
size to handle the connected load. The specplate on the evaporator is marked with the electrical ratings.
Consult the wiring diagram in the electrical end. Determine if the evaporator fans require a separate
power source or if powered by the control circuit. Field wiring should enter through electrical bushings
and conduit must be sealed internally to prevent outside air being drawn in. Check wiring connections
to be sure they did not vibrate loose in shipment. Spin each fan blade to be sure it turns freely.
