ERV
UNIT OPERATION
Today’s houses are constructed using energy−saving building
practices and technologies. These practices and innovations help
reduce your utility bills, but prevent the introduction of fresh air.
Without ventilation, stale air and contaminants remain in the air for
extended periods of time. Stale, unhealthy air is generated from a
variety of sources including everyday living functions, cooking,
cleaning, painting, exhaust from attached garages, and off−gassing
of chemicals used in construction and furnishings. Your ERV
brings in fresh air and circulates it through your home around the
clock and expels stale air to help reduce the stuffy effects of
trapped indoor air.
The actual rate of ventilation is determined by the size of your
home, the number of bedrooms, and applicable local or national
ventilation codes. Your installing contractor has selected and set an
internal fan speed in the ERV to meet these fresh air requirements.
This unit is normally installed without a separate wall−mounted
control. It is generally wired directly to your furnace or fan coil
unit. The blower motor in the furnace or fan coil works in
conjunction with the two blowers in the ERV to circulate the air
through the ERV and duct system. There are no controls, settings,
or functions that need to be adjusted or changed by the
homeowner.
Continuous ventilation is provided when your thermostat is set
to the constant fan mode.

MAINTENANCE
Fig. 3 − ERVCRNVA Components
1. The motors are factory lubricated. Lubricating the bearings
is not recommended.
2. A dirty air filter will cause excessive strain on the blower
motor. The filters in your ERV are washable and should be
cleaned every three 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, then air dry. Replace filters only
when they are completely dry.
3. 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 605F (165C) and 755F
(245C) 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.
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 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.
If your ERV still fails to operate properly, contact your servicing
dealer. Give the dealer your model and serial number. With this
information, the dealer will be able to correct any problems.
NOTE: During cold weather operation, it is possible for a small
amount of frost to accumulate on the heat exchange core inside the
ERV. If a large amount of frost or icing is present on the core,
ventilation performance will be reduced, and melting ice or frost
from the core may result in water damage. If you see a large
amount of ice or frost on the core, or water dripping from or
underneath the ERV, contact your installing contractor.
