Your ERV is designed to operate as an integral part of your total
heating and cooling system (See Fig. 2).
Low Exchange Mode—If the relativehumidity inside the building
is lower than selected, air exchange would occur with the outside at
high speed. If therelativehumidity levelinsidethe 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

PERFORMING ROUTINE
MAINTENANCE
1. The motors are factory lubricated. Lubricating the bearings
is not recommended.
2. The core should be vacuumed every threemonths to remove
dust that would inhibit the energytransfer. 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 nottry to service the core.
The air passages can bedamagedand/or closed off by handling itor
trying to remove it.

motor. The filters in your ERV are washable and should be
cleaned every 3 months. Use avacuum 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
