DUCTING TO HVAC SYSTEMS
CAUTION!
PLEASE NOTE: RETURN TO RETURN INSTALLS ARE TO BE CONSIDERED LAST RESORT OPTIONS AND
ARE NOT RECOMMENDED. THE DEHUMIDIFIER WILL HEAT THE AC COOLING COILS WHICH DIMINISHES
THE AMOUNT OF WATER THE AC SYSTEM WILL REMOVE WHEN OPERATING. IF THIS INSTALLATION IS
CHOSEN, THE DEHUMIDIFIER MUST ACTIVATE THE HVAC BLOWER AND AC CALLS NEED TO LOCK OUT THE
DEHUMIDIFIER FROM RUNNING. PLEASE CHECK YOUR LOCAL CODES PRIOR TO INSTALLING.
c. Dedicated Ultra Series Return to HVAC Return
Create a separate return for the Ultra
Series Dehumidifier in a central area of
the building.
Installing the supply air from the Ultra
Series Dehumidifier to the return of the
HVAC system requires the HVAC fan to
run when the Ultra Series Dehumidifier
is operating.
d. HVAC Return to HVAC Return
If Check Damper is not in place, the
HVAC fan must turn on when the
dehumidifier is in operation.
e. No Existing Ductwork Installation
When installing the Ultra Series Dehumidifier in a structure that does not have a forced-air HVAC system or is
not being tied into the system, a single return for the Ultra70 should be installed in a central location.
Install a 6" insulated duct from outside, teeing into the 8" return duct of the Ultra Series Dehumidifier to provide
outdoor air ventilation (optional).
The supply of the Ultra Series Dehumidifier should be ducted to the rooms in the home that have the ductless
mini-split heads and as close to the heads as possible. Be sure to utilize multiple rooms to allow air inside the
structure to properly circulate. Proper air distribution is important to ensure even humidity control and heat
distribution throughout the structure.
A 6" diameter duct is recommended for branches to bedrooms. An 8" diameter duct is recommended for
branches to larger areas.
• DO NOT locate return in a bathroom or
kitchen.
• DO NOT locate the supply in rooms
where doors may be closed.
• Control should be located remotely
from the dehumidifier and placed in a
central location.
