be in compliance with local codes and be
complete, tight, and leak free.
Ducts should be as short as possible, not to
exceed 100 ft. equivalent length and supported in
compliance with the manufacturer’s
recommendation.
CAUTION!
All duct connections must be sealed. Any
leakage in the duct work will adversely affect
the operation of the dehumidifier and may
lead to unsatisfactory performance.
DAMPERS
Optional dampers may be installed in the outlet
duct, inlet duct, or in an outside air duct. These
dampers must be full flow motorized type. Do not
use any type of pressure operated damper as
unacceptable pressure drop will affect unit
operation. All dampers must be installed in
compliance with the manufacturer’s
recommendations and be insulated, and sealed
per the section on ducts, above.
ELECTRICAL
POWER WIRING
WARNING!
Turn off electrical power at the fuse or
service panel before making any electrical
connections. The ground connection must
be completed before making line voltage
connections. Failure to do so can result in
electrical shock, severe personal injury or
death. The dehumidifier must be installed so
that the electrical components are protected
from water from any source.
WARNING!
The cabinet must be permanently
grounded. Connect the ground wire to the
Ground terminal provided in the unit. Failure
to ground the cabinet can result in fire,
electrical shock, personal injury or death.
The electrical supply requirements are listed on
the unit rating plate and in the specification table
above.
CONDENSATE DRAIN
The condensate drain must be trapped external to
the unit. The trap dimensions must be equivalent
to the dimension of the trap on the associated air
conditioner air handling unit to prevent water
being removed from the trap when the A/C unit is
running.
A drain line must be attached to the trap outlet
and pitched away from the unit a minimum of 1/8"
per foot to allow the condensate to flow away
from the unit.
DUCTS
The unit is furnished with two beaded 8" round
collars for duct connections to the inlet and the
outlet of the dehumidifier. These are located
inside the unit and must be attached to the unit by
the installer using screws and gasket or caulking.
Center the collars over the inlet and outlet
openings in the cabinet.
Insulated flexible ducts in compliance with
Underwriter’s Laboratory’s (UL)
Standard for
Factory Made Duct Materials, UL-18
and installed
per the manufacturer’s recommendation should
be used to connect the dehumidifier to the air
conditioner. The installation and connections must
