•   Install the unit close to the outside 

wall on which the supply and 
exhaust hoods will be mounted.

•   Have a nearby power supply 120 

Volts, 60Hz. (power cord is 3 
feet long)

•   Mount the unit as level as 

possible in order to allow proper 
condensate drainage. 

•   Have access to a water drain for 

the condensate of the unit during 
defrost.

•   Have a certain amount of heat 

around the unit (attic installation 
is not recommended).

•   Installations close to the living 

space, such as closets, should be 
designed to minimize noise or 
vibration transfers.

•   Have access for future  

 

maintenance. (10” is 
recommended for removal of core)

INSTALLATION

PRACTICAL TIPS

1

   Install the drain nipple.

INSTALLING DRAIN LINE - 

Drainline not included in kit

Through normal operation and during its defrost mode, the HRV may produce some condensation. This water should 
flow into a nearby drain, or be taken away by a condensate pump. The HRV and all condensate lines must be installed in 
a space where the temperature is maintained above the freezing point. A “P” trap should be made in the drain line. This 
will prevent odors from being drawn back up into the unit.

MOUNTING - EASY WALL MOUNT

LOCATION

 

The HRV must be located in a heated space where it will be possible to conveniently service the unit. Typically the HRV 
would be located in the mechanical room  or an area close to the outside wall where the weatherhoods will be mounted. 
If a basement area is not convenient or does not exist, a utility room or laundry or closet may be used.
Attic installations are not normally recommended due to:
 

- the complexity of work to install

 

- freezing conditions in the attic

 

- difficulty of access for service and cleaning

Connecting the following appliances to the HRV 

is not recommended

,

 including:

 

- clothes dryer

 

- range top

 

- stovetop fan

 

- central vacuum system

 These appliance may cause lint, dust or grease to collect in the HRV , damaging the unit.

NOTE:

 Connecting any of these type of appliances to the HRV will invalidate your warranty

ELECTRICAL

3 prong plug-in power cord.

  Attach bracket to wall, lift unit    

(30 lbs/13.5 kg) & slide nuts into 
slots on bracket, tighten screws to 
secure unit to bracket. Insert the 
safety screws & place wall bumpers 
to level off the unit.

Safety screws (included)

  Place bumpers on back 

of unit (included)

16” (406mm)
