MAINTENANCE
1. The motors are factory lubricated. Lubricating the bearings
is not recommended.
2. The core should be vacuumed every three months to remove
dust that would inhibit the energy transfer. Do not use
water. The core should only be serviced when the
outdoor temperature is between 60°F (16°C) and 75°F
(24°C) and dry.
NOTE: If the edges of the core are soft, do not try to service the
core. The air passages can be damaged and/or closed off by
handling it or trying to remove it.
3. A dirty air filter will cause excessive strain on the blower
motor. The filters in your ERV are washable and should be
cleaned every 3 months. Use a vacuum cleaner to remove the
heaviest portion of accumulated dust, then wash in warm
water.
NOTE: Do NOT clean these filters in a dishwasher or dry them
with heating appliances as they will be permanently damaged. Use
lukewarm water to clean filters. Replace filters only when they are
completely dry.
4. Regularly check the screen on the exterior intake hood and
clean as necessary.
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 servic-
ing 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 duct-
work. 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
(--5°C), some degree of defrost mode is possible. Defrost length
could be 5 to 20 minutes, depending on temperature and set-
tings.
If your ERV still fails to operate properly, contact your servicing deal-
er. Give him your model and serial number. With this information, the
dealer will be able to correct any problems.
