INSTALLATION,
IMPORTANT - PLEASE READ THIS MANUAL
CAUTION -
Before installation, careful consideration must be given to how this system
will operate if connected to any other piece of mechanical equipment, i.e. a forced air furnace
or air handler, operating at a higher static. After installation, the compatibility of the two piec-
es of equipment must be confirmed by measuring the airflow's of the Heat Recovery
Ventilators by using the balancing procedure found in this manual.
It is always important to assess how the operation of any HRV may interact with vented com-
bustion equipment (i.e. Gas Furnaces, Oil Furnaces, Wood Stoves, etc.).
NEVER -
install a ventilator in a situation where its normal operation, lack of operation or par-
tial failure may result in the backdrafting or improper functioning of vented combustion equipment!!!

Page 11: Operation
OPERATION A Heat Recovery Ventilator (HRV) is designed to bring fresh air into a building while exhausting an equal amount of stale air. During the winter months, the incoming cold fresh air is warmed by utilizing the heat recovered from the stale air before it is exhausted to the outdoors. During summer months when the indoor space is air conditioned, the HRV will help in cooling the incoming fresh air with the stale air that is being exhausted. -
Page 12: Optional Remote Controls
OPERATION (CONT'D) OPTIONAL REMOTE CONTROLS * All controls are low voltage. 18 to 24 PRACTICAL gauge wire is recommended. TIPS Dehumidistat I - The wall mount dehumidistat monitors the humidity level in the area it is installed. When the humidity level rises above the desired set-point, the HRV will activate to high speed/override mode. -

INSTALLING DUCTS GOING TO / FROM OUTSIDE A well designed and installed ducting system will allow the HRV to operate at its maximum efficiency. Always try to keep duct runs as short and straight as possible. See Installation Diagrams for installation examples. INSTALLING THE DUCTING PRACTICAL TO THE WEATHERHOODS... - Page 15 INSTALLING DUCTS TO / FROM INSIDE To maximize airflow in the ductwork system, all ducts should be kept short and have as few bends or elbows as possible. Forty-five degree are preferred to 90º elbows. Use “Y” tees instead of 90º elbows whenever possible. All duct joints must be fastened with screws or duct sealant and wrapped with a quality duct tape to prevent leakage.
- Page 16 INSTALLING DUCTS TO / FROM INSIDE (CONT'D) Exhaust Air Ducting The stale air exhaust system is used to draw air from the points in the house where the worst air quality problems occur. It is recom- mended that return air ducts be installed in the bathroom, kitchen, and laundry room. Additional return air ducts from strategic locations (i.e.

Page 17: Installation Examples
INSTALLATION EXAMPLES It is the responsibility of the installer to ensure all ductwork is sized and installed as designed to ensure the system will perform as intended. All air movement devices have a performance curve. The amount of air (CFM) that an HRV will deliver is directly related to the total external static pressure (E.S.P.) of the system. -
