Drain Connection (AIR125R and AIR125F Only)
Installation Notes
The AIR125 HRV's have a 4-position drain spout to allow for easy and quick installation of the
condensate drain hose (see below).
The AIR125 HRV's may produce some condensation during a defrost cycle. This water should flow
into a nearby drain, or be taken away by a condensate pump.
1. Position drain spout towards desired drainage direction and fasten to HRV cabinet with 4 sheet
metal screws provided.
2. Seal drain spout to bottom of HRV cabinet with silicone.
3. Cut one length of 1/2 in drain hose (not included) and connect to the drain spout.
