9. CONDENSATION DRAIN LINE
10. 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
(included in drain kit). 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 115v. It is not recommended to
connect unit with an extension cord.
figure 10.1 Insert the power cord on top of the unit. Press
firmly
to
make sure the power cord is secure.
figure 10.2 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 9.1 Make a loop in condensate line, not be subject to
freezing temperatures.
figure 9.2 Use a condensate pump if you don’t have access to a drain.
11. 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
