• 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, 60 Hz.
• Have the possibility of
mounting the unit to
supporting beams.
• Mount the unit as level as
possible in order to allow
proper condensate
drainage. Failure to do so
may void warranty.
(HRV-XI 450 only)
• Have access to a water
drain for the condensate of
the unit during defrost.
(HRV-XI 450)
• The HRV-XI or ERV-XI
can be accessed for regular
maintenance by both sides
using one of the two
latched doors. Leave
appropriate clearance.
INSTALLATION
PRACTICAL
TIPS
Installing Drain Line (HRV-XI 450 only)
Through normal operation and including defrost mode, the HRV-XI 450 may pro-
duce 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. The drain connection is a 1/2" NPT nipple.
MOUNTING
LOCATION
The HRV/ERV must be located in a heated space where it will be possible to conve-
niently service the unit. Typically the HRV/ERV would be located in the mechanical
room, above a drop ceiling or an area close to the outside wall where the weather-
hoods will be mounted. Attic installations are not normally recommended due to
extreme temperatures, and difficulty in performing, required service & maintenance.
If an attic is slected, special care should be taken in ensuring the unit will perform
as intended. Unit may need to be protected with insulated shelter, built on site.
Connecting appliances to the HRV/ERV
It is not recommended, including:
- clothes dryer
- kitchen exhaust hoods
- combustion venting
- 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
