UNIT INSTALLATION 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. 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.
PAGE 3
Step 3—Forced-Air Application Step 6—Locate and Install Exterior Hoods Most HRV applications will be installed in conjunction with new or existing forced-air system. To operate properly, the fresh-air supply and stale-air return from HRV connect directly to return-air duct system. This is how the HRV distributes fresh air and removes stale air from inside of building. (See Fig. 7.) For these installations, furnace or fan coil blower must be interlocked and operate continuously whenever HRV is energized.

WALL CONTROL Step 4—Automatic Control Operation Step 1—Location This control contains an adjustable dehumidistat and push button switch to cycle between 3 modes of operation. There are 5 LEDs to indicate mode of operation. (See Table 3.) The HRV wall controls are unique to HRV and must be installed for proper unit operation.

If 2 flow collars are available, it will be much easier to read airflow and properly adjust dampers to balance unit. MAX MIN AIRFLOW DIRECTION 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.

Example: 11 rooms X 10 CFM + 2 X 20 CFM = 150 CFM.

Step 2—Filter Step 3—Blower Motor Filters in HRV are washable and should be cleaned every 3 months. Use a vacuum cleaner to remove heaviest portion of accumulated dust, then wash in lukewarm water. Allow filter to completely dry before reinstalling. A dirty air filter will cause excessive strain on blower motor. Never operate unit without a filter. Vacuum out debris. The HRV blower motor operates on 115vac, with 2-speed operation.
