BEFORE YOU REQUEST
A SERVICE CALL
S Check 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.
S Check 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.
S Check 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.
