ELECTRICAL CONNECTIONS
The DCA unit is factory pre-wired. Field wiring is limited
to power wire and the installation of wiring for 24V
controls.
Provide and install a main disconnect switch within
close vicinity of the dehumidifier. Refer to the unit
nameplate or electrical information (Following Chart) for
proper voltage, minimum ampacity and maximum main fuse
protection. All wiring and main disconnect switch should
be provided in accordance with all local, state and national
electric codes (N.E.C.).
IMPORTANT
Make sure the DCA unit is properly grounded with
correct gauge of wire via the ground lug terminal located in
the control panel. Failure to properly ground unit will void
all warranties. Supply voltage must not vary more than 10%
of the nameplate voltage while the unit is operating.
Chart A
Fuse & Ampacity Rating
The control wiring should be done according to the
wiring diagram provided with the unit. The DCA control
circuit operates at 24V.
CONTROLS, LOCATION & MOUNTING
Locate controls in an area of natural room air
circulation usually near the return air inlet. Avoid areas of
hot spots from warm air ducts, radiators or exposure to
sunlight or direct room lighting. Avoid mounting controls on
cold outside masonry walls, near door, windows or air
conditioning outlets.
Do not locate controls in a room that is not being
conditioned by the dehumidification system, unless system
has remote sensors (optional).
Controls should be mounted 5 feet from floor level on an
interior wall. All controls must be level.
