PERFORMING ROUTINE MAINTENANCE
! WARNING: Before servicing system, always turn off main power to system. There may be more than 1 disconnect switch.
Turn off accessory heater power if applicable. Electrical shock can cause personal injury or death.
!
CAUTION: Although special care has been taken to minimize sharp edges in the construction of your unit, be extremely
careful when handling parts or reaching into the unit.
1. The motors are factory lubricated. Lubricating the bearings is not recommended.
2. The heat recovery core must be handled with care. To ensure maximum efficiency of the plastic partitions wash core once a
year following the season of most intense use.
Allow the heat recovery core to soak for 3 hr in a solution of warm water and mild soap. Rinse under a heavy stream of warm
water. Hot water and strong detergent should NOT be used, as it will damage the heat recovery core.
3. A dirty air filter will cause excessive strain on the blower motor. The filters in your HRV 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.
The Air Exchange Indicator light on the auto control will indicate when filters should be cleaned. The light will flash on and
off until the door is opened to service the unit.
4. Regularly check the screen on the exterior intake hood and clean as necessary.
5. Examine the condensate drain pan to ensure drains are functioning properly. Gently clean tray with mild soapy water.
(See Fig. 2 and 3.)
BEFORE YOU REQUEST A SERVICE CALL
• 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 sec-
ond time.
• Check for sufficient airflow. Check air filters for accumulations of large particles. Check for blocked exhaust-air grilles or duct-
work. Keep grilles and ductwork open and unobstructed.
• If the condensate fails to drain properly, check the grommet and drain tube for obstructions. Make sure that the condensate drain
tube has a slight slope and is not kinked.
If your HRV still fails to operate properly, contact your servicing dealer. Give him your model and serial number. With this infor-
mation, the dealer will be able to correct any problems.
