Unit should be synchronized with AHU/furnace operation to avoid Stale
air from bathroom condensation and mold growth in furnace/AHU
distribution ducting if cooling mode of furnace/AHU is used.
This configuration is not recommended with high velocity furnace.
NOTE:
For this type of configuration, the T-3 option must be selected
on the LCD screen when auto-balancing the unit.
SIMPLIFIED INSTALLATION (T-4)
A200565
Fig. 8 – Simplified Installation
For this type of installation, the furnace/AHU
must always be
synchronized
with the unit in order to maximize the amount of fresh air
to the building
(CONNECTION TO THE FURNACE/AHU on p9)
When performing duct connection to the furnace/AHU, installation must
be done in accordance with all applicable codes and standards. Please
refer to your local building code.
Fresh air and exhaust air flow through the furnace/AHU ducts, which
simplifies the installation.
The use of bathroom fans and a range hood is suggested to exhaust stale
air.
STALE AIR EXHAUST DUCTWORK:
Connect the stale air intake port of the unit to the furnace return duct at
least 3 feet ahead of the fresh air distribution from the unit.
FRESH AIR DISTRIBUTION:
Connect the fresh air distribution duct of the unit to the furnace return
duct at least 10 feet away from the furnace (A+B).
NOTE:
This 10-ft. distance applies only in areas where the outside
temperature falls below the freezing point 0°C (32°F).
NOTE:
For this type of configuration, the T-4 option must be selected
on the LCD screen when auto-balancing the unit.
ALTERNATE INSTALLATION (T-5):
A200566
Fig. 9 – Alternate Installation
Unit should be synchronized with AHU/Furnace operation to building
avoid condensation and mold growth in furnace/AHU distribution
ducting if cooling mode of furnace/AHU is used.
NOTE: For this type of configuration, the T-5 option must be selected on
the LCD screen when auto-balancing the unit.
CONNECTING THE DRAIN (HRV ONLY)
• Cut the appropriate length of drain tubing (
).
• Connect the tubing to the provided adapter.
• Make a water trap loop in the tube to prevent the unit from drawing
unpleasant odors from the drain source.
• Add water in the loop to prevent noise or hiss.
• Make sure there is a distance of at least 2" between the unit and the
tubing loop.
• Using the tie wrap provided, attach the tubing as illustrated.
• Run the tube to the floor drain or to an alternate drain pipe or pail.
IMPORTANT:
If using a pail to collect water, place the tube end
approximately 1" inside the pail in order to prevent water from being
drawn back up into the unit.
