Kit Wiring Instructions for HE1XIN Isolation Dampers
Insure all electrical power is disconnected from the unit.
Turn off disconnect switch on door of unit.
Using a Phillips head screw driver, remove the three (3) ¼”-20 X
1¾” long safety screws from the door.
Swing door open, and locate the electrical box.
Using a Phillips head screw driver, remove the two (2) #8 X ½” long
screws that hold the cover on the electrical box.
Remove the electrical box cover.
Remove the two black outer plugs at the locations where the white
Molex connectors will install (See Page 4 dimension drawings).
From the outside remove the insulation that is behind the black
plastic plugs.
Two identical wire harnesses are supplied. (One for the “EA”
damper and one for the “FA” damper.)
Push the low voltage connecting plug in to the rectangular hole
located in the motor mounting plate.
Apply caulk to seal plug as this is a leak path to outside of unit.
Route wires in to the electrical box.
Installation
Dampers for this model are designed for installation indoors.
Dampers for this model are designed to be installed in both the Exhaust Air and Fresh Air locations.
(See airstream location stickers on side of unit).
You can determine what unit control your ERV has by digit #19 in
the Model # on the unit rating label as follows:
A = Standard Unit (Non-IBC)
D = IBC (Independent Blower Control)
T = ECM (Electronically Commutated Motors)
This damper kit can be installed in models built on or after G12
(July 2012) as found in the Serial Number on the unit rating label.
For any serial # with the rst 3 places tp be G, H, I, J, K, L 12 are
compatible and any model with 13 and higher are also compatible.
Locate the SPST isolation relay/s:
Non Independent Blower Control (Label 165950):
Has only has one (1) SPST isolation relay.
Remove all of the quick connections from the relay (2 yellow
wires, 1 red and 1 orange wire).
Cut off the quick connects and strip wire ends back approximately 3/8”
Using the Heyco connectors (supplied):
• Connect the 2 blue wires on the “EA” and “FA” wire
harnesses to one of the yellow wires that came off the relay
(NOTE: It doesn’t matter which yellow wire you choose).
• Connect the 2 yellow wires on the “EA” and “FA” wire
harnesses to the other yellow wire that came off the relay.
• Connect the red wire from the “FA” harness to the red wire
that came off the relay.
• Connect the orange wire from the “EA” harness to the
orange wire that came off the relay.
• Connect the orange wire from the “FA” harness to the red
wire from the “EA” harness.
Wiring Installation Instructions
Depending on Unit Control
When complete, before placing the cover back on the electrical box,
apply the supplied wiring schematic label over the old one on the
inside of the electrical box cover based on the unit control scheme.
Slide the cover back on the electrical box and re-secure with the
two (2) #8 X ½” screws.
Swing door closed and replace the three (3) ¼”-20 X 1¾” long safety screws.
Remove damper assemblies from carton. The motorized actuator
is pre-installed and needs no adjusting.
Slide damper assembly onto the factory installed round duct
collars on the unit at the appropriate location(s).
Secure damper assembly in appropriate manner.
Continue ducting the unit as described in the Installation and
Operation Manual that came with the unit.
Plug the dampers actuators in to the Molex connectors that were
just installed.
Use conduit, strain relief etc. as required by code to secure
damper wiring.
Reconnect power and turn the disconnect switch on the unit door
to “ON”.
NOTE: When the unit calls for ventilation the blowers will not
immediately start, the damper blades are opening and when they
are approximately 60 % open, the blowers will start. Actuation
time is approximately 75 seconds.
