WARNING
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in
personal injury or death. Disconnect electrical
power to the HVAC system before proceeding.
CAUTION
CUT HAZARD
Failure to follow this caution may result
in personal injury. Sharp metal edges can
cause personal injury from cuts. Use gloves
when cutting plenum openings and handling
ductwork.
Fresh Air Vent Damper and Control
This product must be installed by a qualified HVAC contractor.
Failure to follow this caution may result in unit component damage.
Do not mount the Ventilation Controller on the supply plenum or duct. The
unit will malfunction at heated temperatures and lose its calibration.
When installing the Ventilation Controller on downflow furnaces, ensure
that the blower continues to run after the heat call is satisfied to prevent
high temperatures from damaging the Controller circuit board.
Do not mount the Ventilation Controller downstream from any fresh air
intake port, humidifier or bypass outlet. False humidity conditions will
cause the Ventilation Controller to operate incorrectly.
