Mounting the Unit
Note: Only the AIR 140-ERVF and AIR 180-ERVF-ECM have the option of wall mounting
the unit.
1.
Using the hardware provided, install the mounting brackets on the unit. It is important to
isolate the mounting brackets from the mounting surface to minimize vibration.
2.
Install the unit to the mounting surface, using the mounting brackets provided.
Do not drill additional holes in the HRV / ERV
Due to natural condensate accumulation, the unit must have the door hinges directed towards the floor in wall mount configuration
(AIR 140-ERVF & AIR 180-ERVF-ECM only).
Installing the Drain Connection (HRV's only)
Applicable Unit: AIR 125-R.
The HRV's have a 4-position drain spout to allow for easy and quick installation of the
condensate drain hose (see below). The HRV may produce some condensation during a
defrost cycle. This water should flow into a nearby drain or be taken away by a condensate
pump.

The preferred direction is with spout directed towards the hinges of the door for ease
of future maintenance of the unit.
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.
PLEASE NOTE: Installer should consider location of the drain spout in respect to the
service and maintenance.
•
The HRV and all condensate lines must be installed in a space where the temperature is maintained above the freezing point or freeze
protection must be provided.
•
Drain trap and tubing must be below bottom of door with 1/4 in per foot downwards slope away from unit.
•
A secondary drain pan may be required to protect from condensate leakage.
