Raise slightly the corner of the end piece (locking tabs) and mate with side piece (slots), ensuring that lower locking tab with leading edge is through slot opening.
13 Dr ains Connect the stainless steel drain pans in the bottom of the HRV to a drain line fastened to the holes provided. See pg.10 for location of the drain pans and the drain connections. Create a "P" trap to prevent odours from being drawn through.
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.
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.
