BALANCING THE UNIT
IO-VENT-NC WWW.CLEANCOMFORT.COM

TOOLS REQUIRED TO
BALANCE THE HRV/ERV
• A Magnehelic gauge capable of
measuring 0 to 2.0 inch of water
(0 to 500 Pa) and two (2) plastic
hoses.
• A balancing reference chart
located on the HRV/ERV access
door panel.
CONSIDERATION WHEN
BALANCING THE HRV/ERV
• Seal all the unit ductwork with
tape. Close all windows and
doors.
• Insure all exhaust devices such as
range hood, dryer and bathroom
fans are OFF.
• Make sure that all lters are
clean and that there is no
obstruction in ductwork
• Make sure that the forced air
system blower is “ON” when
connected to an existing forced
air system ductwork.
• If it is a direct duct system
installation ensure forced air
system blower is “OFF”.
USING THE DUOTROL
SELECTOR SWITCH
When on Balancing Mode, the
Selector Switch allows you to

IMPORTANT: Insure the HRV/ERV
has completed the defrost sequence.
That the dehumidistat is deactivated
by turning the round dial to the “OFF”
position, the Range is” NORMAL”, the
mode is “CONT” and the Cycle per
Hour is set at “0/0”.
NOTE: The unit is considered
balanced even if there is a dierence
of ±10 cfm (or ± 5 l/s or 17 m³/h)
between the two air ows
DUOTROL™ BALANCING SYSTEM PROCEDURES
Step 1: Place the Magnehelic gauge on a level
surface and adjust the needle to zero.
Step 2: Connect the two (2) plastic hoses to the
gauge on the HIGH & LOW pressure connections.
Step 3: Once the total ventilation requirements are
determined, you can start balancing the HRV/ERV.
(Refer to 1. Ventilation Requirements)
Step 4: Remove the (4) four nylon knock out seals
located on the HRV/ERV access door. (Ref g 11.1)

Note: If the gauge needle drops below zero,
reverse the plastic hose connections.
Step 6: Press the (+) and (–) buttons on the
Duotrol™ simultaneously until you see the yellow
light. Once the indicator light turns yellow and the
unit goes to high speed you are in balancing mode.
When in balancing mode the selector switch on
the Duotrol™ becomes the motor selector switch.
INTER (Right Motor = Stale Airow), CONT (Both
Motors) and OFF (Left Motor = Fresh Airow)
Step 7: To adjust the (fresh air), select the «OFF»
position on the Duotrol™. Ensure the plastic hoses
from the gauge are connected to the HIGH & LOW
balancing pressure taps on the fresh airow side
located on the HRV/ERV access door. (Ref Fig 11.2).
To adjust the airow rates, press the (–) button to
decrease or press the (+) button to increase the
airow rates until you reach the calculated fresh
airow requirements.
Step 8: To adjust the (stale air) select the «INTER»
position on the Duotrol™. Ensure the plastic hoses
from the gauge are connected to the HIGH &
LOW balancing pressure taps on the stale air side
located on the HRV/ERV access door. (Ref Fig 11.2)
To adjust the airow rates, press the (–) button to
decrease or press the (+) button to increase the
airow rates until you reach the calculated stale
airow requirements.
Step 9: Once this is completed, you have balanced
the airow rates of your HRV/ERV. To exit the
balancing mode you must press (+) and (–) buttons
on the Duotrol™ simultaneously until solid green
LED appears then release. The indicator light will
turn green to indicate normal operation mode.
Seal the (4) four balancing pressure taps with the
nylon knock out seals removed in Step 4.
Step 10: Mark down the balanced air ow rates
information on a label including in the kit. Apply
the label to the HRV/ERV access door for future
reference (e.g. date, balance airow rate, your
name, phone number and business address).
Note: Once the HRV/ERV is balanced, switch
to «CONT» on the Duotrol™ By using (+) and (–)
buttons you can set the continuous speed.
