F an Defrost The Models 2500IFD and 2500EFD are equipped with an electronically controlled fan defrost system to remove frost that collects on the warm air side of the aluminum heat transfer surfaces of the heat exchanger core. When the outside temperature drops below 27˚F(-3˚C), a defrost timer is activated which provides for an auto- matic defr[...]

14 Stale Air Return S yst em The stale air return system is used to draw air from the points in the building where the worst air quality prob- lems occur . Balancing dampers and/or adjustable grilles are recommended on all return air lines which are used during installation to help balance the "draw" from different areas of the building. [...]

15 It is necessary to have balanced air flows in an HRV. The volume of air brought in from the outside must equal the volume of air exhausted b y the unit. If the air flows are not properly balanced, then; • The HRV may not operate at its maximum efficiency • A negative or positive air pressure may occur in the house • The unit may not defros[...]

16 The Integr ated HV A C S ystem The 2500 is a quiet, efficient, low pressure system. Special care and attention should be given if connecting this unit to any other air handler that may draw more air than the 2500 is designed to accommodate. The HRV has become an integral component of the HV AC system. Figure 4 shows an HRV unit provid- ing fresh[...]
