Matrix Installation and Operation Instructions
11.3 Damper Box
Included in the installation kit is a damper box. This
damper box eliminates the infiltration of cold outside
air when the HRV is off or in defrost mode. It is to
be installed with the actuator on the top side and
screw to the Matrix using the four screws provided.
11.4 Condensate Drain
Condensation from defrost will collect in the
ventilator and drain from the sloped drain pan.
This condensation must be evacuated from the
unit. The condensate tubing provided must be
routed through the hole in the side of the
appliance and attached to the 90° elbow directly
underneath the ventilation module. From there
the condensate tube must be emptied into a
suitable floor drain or if necessary the emptying
drain must have a trap to prevent the infiltration
of toxic gases.
IMPORTANT
When using the Simplified System method, exhaust connection to the return must be 4’ from where the
return connects to the Matrix.
IMPORTANT
All main HRV ductwork to be 6” round.
Exterior connections are to be insulated and include a vapor barrier.
