When you see this symbol on the unit and in instructions or manuals,
be alert to the potential for personal injury. Understand these signal
words; DANGER, WARNING, and CAUTION. These words are
used with the safety- -alert symbol. DANGER identifies the most
serious hazards which will result in severe personal injury or death.
WARNING signifies hazards which could result in personal injury
or death. CAUTION is used to identify unsafe practices which may
result in minor personal injury or product and property damage.
NOTE is used to highlight suggestions which will result in
enhanced installation, reliability, or operation.
OPERATING YOUR ENERGY RECOV-
ERY VENTILATOR (ERV) WITH
ONETOUCH CONTROL
Press "PUSH" until the desired ventilation operation is selected.
There are three selections: High, Low, Intermittent. The power indi-
cator light indicates which mode has been selected.
High: This mode is recommended for the removal of excess pollu-
tants and humidity. The ventilator will operate at its maximum speed
continuously. The power indicator light will be lit red when this
mode is selected.
Low: This mode is recommended for normal daily operation. The
ventilator will operate at its minimum speed continuously. The
power indicator light will be lit yellow when this mode is selected.
Intermittent: This mode is recommended when the inside air is too
dry in the heating season or too humid in the cooling season. The
ventilator will operate at its minimum speed for 20 minutes per hour
and be off for 40 minutes per hour. The power indicator light will
be lit green when this mode is selected.
Off: To turn the ventilator off, press "Push" until the power indicator
light is turned off.
OPERATING YOUR ENERGY RECOVERY
VENTILATOR (ERV) WITH BASIC,
STANDARD AND AUTOMATIC CONTROL
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 relative humidity inside the building
is lower than selected, air exchange would occur with the outside at
high speed. If the relative humidity level inside the building is high-
er 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

than selected, air exchange would occur with outside at high speed.
This mode is ideal for maintaining the proper humidity level when
the continuous mode cannot.

PERSONAL INJURY HAZARD
Failure to follow this caution may result in personal
injury.
Although special care has been taken to minimize sharp

careful when handling parts or reaching into the unit.
PERFORMING ROUTINE
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 wil 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.
