6. CONDENSATION DRAIN LINE
7. DEDICATED ELECTRIC RECEPTACLE
Insert the threaded drain adapter thru the
bottom of the HRV/ERV and hand tighten
the plastic nut, and with a wrench tighten
the nut another half turn to assure a
better seal.
Install the condensate line. Insert
condensate tubing by pushing clear
plastic line over drain adapter. Make
condensate trap by looping the clear
plastic tubing. This procedure is to
avoid foul odor to enter the HRV or ERV.
IMPORTANT:
Always consult a certified
technician to insure proper installation
of main power.
Note:
If LED light on the Duotrol
remains green, motors not energized
controls do not operate. Polarization in
main AC outlet are inverted.
It is recommended that the HRV/ERV
have a dedicated receptacle with 120v.
It is not recommended to connect unit
with an extension cord.

Insert the power cord on top of the unit. Press
firmly
to make
sure the power cord is secure.
figure 7.2
It is recommended that the HRV or ERV have a dedicated
receptacle with 115v. It is not recommended to connect unit with an
extension cord. If no receptacle is available please call an electrical
contractor and have one installed. Insure polarized is correct
figure 6.1 Make a loop in condensate line, not be subject to
freezing temperatures.
figure 6.2 Use a condensate pump if you don’t have access to a drain.
8. OUTSIDE FRESH AIR AND EXHAUST AIR HOODS
Tip to installer:
We recommend and
it is
good practice
to have a minimum
of 6ft (1.83 m) between the supply
and exhaust vents, unless using a
concentric vent design to prevent
contamination of intake air.
Always properly seal the supply &
exhaust hoods to the exterior of the
thermal envelope of the building with
caulk or other similar material to inhibit
air leakage.
Note: Outdoor air intake hoods shall
be located to avoid contamination from
sources such as:
• Exhaust air openings
• Driveways (auto exhaust)
• Combustion appliances
• Gas meters, oil fill pipes
• Garbage containers
• Attics or crawl spaces
• Under deck or other areas of
questionable air quality
