SAFETY CONSIDERATIONS

Recognize safety information. This is the safety-alert symbol ! 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

would turn off. If the relative humidity inside the building is lower 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.

!WARNING

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or death.

Before servicing system, always turn off main power to system. Turn off accessory heater power if applicable. There may be more than 1 disconnect switch.

!CAUTION

PERSONAL INJURY HAZARD

Failure to follow this caution may result in personal injury.

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.

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.
