Low Exchange Mode—If the relative humidity inside the building is lower than selected, air exchange would occur with the outside at high speed. If the relativehumidity level inside the building is higher than selected,air exchange would occur outside at low speed.This en­sures continuous air exchange for constant air quality.
Intermittent Mode—If the relative humidity inside the building is higher than selected, no air exchange would occur, and the system would turn off. If the relative humidity inside the building is lower than selected, air exchange would occur with outside at high speed. Thismodeis idealfor maintainingtheproperhumiditylevelwhenthe continuous mode cannot.

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, doso only once. Contact yourservicing 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 (--5°C), some degree of defrost mode is possible. Defrost length could be 5 to20 minutes,depending on temperature and settings.
