BEFORE YOU REQUEST

A SERVICE CALL

SCheck the main power disconnect switch. Verify that the circuit breakers are ON or that fuses have not blown. If you must reset breakers or replace fuses, do so only once. Contact your servicing dealer for assistance if the breakers trip or the fuses blow a second time.

SCheck for sufficient airflow. Check air filters for accumulations of large particles. Check for blocked

exhaust-air grilles or ductwork. Keep grilles and duct work open and unobstructed.

SCheck to see if the unit is calling for air exchange, or unit is in defrost. When outdoor ambient temperature is below 23°F, some degree of defrost mode is possible. Defrost length could be 5 to 20 minutes, depending on temperature and settings.

If your ERV still fails to operate properly, contact your servicing dealer. Give him your model and serial number. With this informa- tion, the dealer will be able to correct any problems.
