ERV INSTALLATION

 

LOCATION

The ERV must be located in a conditioned space where it will be possible to conveniently service the unit. Typically 
the ERV 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 may be used.

Attic installation 

must meet the following conditions:

•  Attic temperature must be above freezing conditions at all times and for best performance should be 12°C 

       (54 °F).

•  The condensate drain (if included) must be installed so that the condensate drains and is protected from freezing.
•  The attic is easily accessible for equipment maintenance and inspection.

Connecting appliances to the ERV

 is not recommended. These include:

•  Clothes dryer
•  Range top
•  Stovetop fan
•  Central vacuum system
•  Bathroom exhaust fans unless they are specifically designed for this purpose

These appliances may cause lint, dust or grease to collect in the ERV, damaging the unit.

Connecting any of these types of appliances to the
ERV will void your warranty.

Mounting- Chain mount

•  Have a nearby power supply 

(120 volts, 60Hz)

•  Choose a location which 

allows the possibility 
of mounting the unit to 
supporting beams.

•  The unit should be level 

in order to allow proper 
condensate drainage

•  To minimize noise, do not 

install unit in living area 

•  Ensure proper drainage

Place fastening hooks on 
the strapping board or 
the floor joists

.

Attach a hanging chain 
(provided) to each 19 mm 
(3/4") bolt (provided) in the 
top 4 corners of the unit 
and tighten.

Hang the unit by slipping 
a link onto the hanging 
hooks, making sure the 
unit is level.

Install a spring on each 
chain. Hook the spring 
in the links so a loop is 
created in the chain. The 
spring will then support the 
unit's weight and absorb 
vibrations.
