Anleitung Zusammenfassung
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 the summer months, the cool outgoing stale air from the air conditioned dwelling is used to cool the incoming fresh air. TOOLS REQUIRED The following is a list of tools you may require for the installation of your Heat Recovery Ventilator: • Jigsaw/ Reciprocating Saw • Electric Drill • Flat Srewdriver • "Robertson" screwdrivers #2 & 3 (square) • Philips (for straps) • Hex head (for sheet metal and electrical box) - Pencil - Extension Cord • Measuring Tape - Knife - Duct Tape - Hammer - Pliers • Crimpers - Snips (Hand shears) For Technical Information Call NUTECH Service Dept. 519-457-1904 TABLE OF CONTENTS Tools Required..........................................................1 Engineering Data.......................................................2 Defrost.......................................................................2 Location for Mounting the HRV.................................2 The Ductwork System ..............................................3 A.

CONTROLS • Lighted power switch • 5 Speed with Off position controlled by high efficiency autotransformer • Defrost light indicates when defrost occurs. This is automatic when outside condition drops below -5°C (23°F) • 24 VAC (low voltage) override of speed control to HIGH speed • Internal Dehumidistat CODES and STANDARDS CSA Approved. All components are UL listed. R2000 Approved. HVI Certified. DAMPER DEFROST These HRVs have an electronically controlled damper defrost mechanism. If the outside temperature drops below -5°C (23°F), the defrost timer is activated. After waiting approximately 17 minutes (during which time the core may experience some nominal frost buildup), the timer activates a motor driven damper door mechanism which opens the defrost port and at the same time closes off the supply air from outside. After approximately 4.5 minutes, the damper operates in the opposite direction to close off the defrost port and reopen the fresh air at the supply port (See Figure #1). The 17 minute wait time and 4.5 minute defrost cycle repeat until the temperature again rises above -5°C (23°F). The defrost mechanism incorporates an easy to "self-test" feature. Each time power to the unit is interrupted (unplugged, then plugged back in or turned OFF then ON, etc.), the unit initiates a defrost cycle. The defrost L.E.D. illuminates and the damper door operates for the pre-set 4.5 minute (approximate) time interval. This allows visual inspection of the operating components involved in the defrost cycle as they perform their function. LOCATION for MOUNTING The Heat Recovery Ventilator must be located in a heat...
