2. Alternative HVAC System Installation
If the Recommended Dedicated Ultra Series Return to HVAC Supply Installation is not possible, there are several
alternative installation options available.
•
DO NOT locate return in a bathroom or kitchen.
•
Control should be located remotely from the dehumidifier and placed in a central location.
•
For basement and crawl space installations, an optional tee can be installed on the Ultra Series Supply.
a. HVAC Return to HVAC Supply
Check Damper should be in place
between the Return and Supply
connections of the dehumidifier.
If Check Damper is not in place, the
HVAC fan must turn on when the
dehumidifier is in operation.
If the system has greater than 0.5" WG
the ducting must be reconfigured.
b. HVAC Supply to HVAC Supply
CAUTION!
TO AVOID THE DEHUMIDIFIER CYCLING IN AND OUT OF DEFROST, IT IS RECOMMENDED THAT THE LEAVING
AIR TEMPERATURE OF THE A/C COIL IS NOT BELOW 55°F. ALSO, THIS INSTALL IS NOT RECOMMENDED FOR
CLIMATES WERE THE HEATING SYSTEM WILL RUN DURING THE SPRING AND FALL TIMES OF THE YEAR, AS
THIS COULD DIMINISH THE WATER REMOVAL CAPABILITY OF THE DEHUMIDIFIER.
If Check Damper is not in place, the
HVAC fan must turn on when the
dehumidifier is in operation.
WARNING
DUE TO PRESSURE RESISTANCE IT IS NOT RECOMMENDED TO USE THE OPTIONAL OUTDOOR AIR INTAKE
WHEN INSTALLING THE DEHUMIDIFIER SUPPLY TO SUPPLY.
