BALANCING THE UNIT
WWW.CLEANCOMFORT.COM IO-VENT-NC
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 o.
• That the integrated balancing
dampers located in the collars are
fully open.(Fresh Air damper ref Fig.
11.5, Stale Air damper ref Fig. 11.6)
• 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”.
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
dierence of ±10 cfm (or ± 5 l/s or
17 m³/h) between the two air ows
Note to installer: For installation
purposes, the VH30100RNC &
VH30140RNC are designed with
pre-determined airow speed
values that are stored in memory.
The VH30100RNC & VH30140RNC
platform are designed and can
be equipped with the Duotrol™
speed & balancing control system
kit. This factory option must be
present to control the motors
independently, when more
accurate airow settings are
required or for testing purposes.
Please contact 1-888-724-5211 for
further instructions/information
on this process.
BALANCING PROCEDURES WITH INTEGRATED BALCANCING DAMPERS
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 four (4) nylon knock out seals
located on the HRV/ERV access door. (Ref Fig 11.3)

Step 6: Set the unit on high speed by connecting
the Vectra EHC-1.0 controller to the HRV/ERV,
power “ON” and select the 20MIN/HR operating
mode by pressing the “PREF” button on the Vectra
EHC 1.0 control.
ATTENTION: If there is no control present on the RNC
1.0, will automatically run on a continuous high speed
operating mode.
Step 7: To adjust the (fresh air), ensure the plastic
hoses from the gauge are connected to the HIGH &
LOW balancing pressure taps on the fresh air side
located on the HRV/ERV access door. (Ref Fig 11.4).
Adjust the fresh airow integrated balancing damper
lever counterclockwise until you reach the calculated
fresh airow requirements. (Ref Fig 11.5).

information on a label including in the kit. Apply
the label to the HRV/ERV access door for future
reference (e.g. date, balance airow rate, your
name, phone number and business address).
For Balancing Charts,
- Refer to page 22 of this manual

the damper lever do not use
a drill or electric screwdriver,
use a standard screwdriver.
