SAFETY CONSIDERATIONS Installation and servicing of this equipment can be hazardous due to mechanical and electrical components. Only trained and qualified personnel should install, repair, or service this equipment. UNIT INSTALLATION CAUTION: Do not install HRV in a corrosive or contaminated atmosphere. Untrained personnel can perform basic maintenance functions such as cleaning and replacing air filters. All other operations must be performed by trained service personnel.

III. FORCED-AIR APPLICATION VI. Fresh-air intake and stale-air exhaust must be separated by at least 6 ft. Fresh-air intake must be positioned at least 10 ft from nearest dryer vent, furnace exhaust, driveway, gas meter, or oil fill pipe. Fresh-air intake must be positioned as far as possible from garbage containers and potential chemical fumes. When possible, it is advised to locate the intake and exhaust hoods on same side of house or building.

WALL CONTROL I. IV. LOCATION The HRV wall controls are unique to HRV and must be installed for proper unit operation. Three wall control options are available: 1. Basic Control 2. Standard Control 1. Initially the switch is off. All LEDs are off and HRV is inoperative. 3. Automatic Control II. 2. First push of mode button puts HRV into intermittent mode. The HRV operates at high speed when there is a call for dehumidification. Intermittent and exchange LEDs are illuminated.

collar in the fresh-air duct and record airflow. If 2 flow collars are available, it will be much easier to read airflow and properly adjust dampers to balance unit. With speed control at maximum speed (high-speed operation) and continuous air exchange occurring with outside, connect hoses from flow collar to a magnehelic gage. (See Fig. 17.) The gage must be leveled and zeroed before use to read accurately. If needle falls below zero, reverse hose connections.

NOTE: If there is a short circuit or an open circuit at thermistor, CPU will go into a 5 minute defrost cycle every 20 minutes. This feature is not there on older board versions with 3pin jumpers. In addition, regularly check and clean screens on exterior intake and exhaust hoods when necessary. CAUTION: DO NOT clean filters in a dishwasher and DO NOT dry them with a heating appliance or permanent damage will result. III.
