INDEPENDENT OPERATION
DUCT CONNECTIONS (Independent
Operation)
In this arrangement, the dehumidifier is connected
across, or in parallel with the air conditioner air
handler. The discharge of the dehumidifier is
connected to the discharge of the air handler, and
the inlet connection of the dehumidifier is
connected to the inlet duct of the air handler.
When the dehumidifier is connected for
independent operation, the central air conditioner
fan and the dehumidifier fan CANNOT operate
simultaneously.
Use a separate fused branch electrical circuit
containing a properly sized fuse or circuit breaker.
Run this circuit directly from the main circuit box
to an electrical disconnect which must be readily
accessible and located within sight of the
dehumidifier. Connect from the disconnect to the
electrical connection within the dehumidifier
utilizing the hole sized for 1/2" conduit provided
on the entering air end of the unit.
WARNING!
L (hot) and N (neutral) polarity must be
observed when making the electrical
connection to the unit.
Installation of the electrical supply line must be in
accordance with the National Electric Code, ANSI/
NFPA No. 70, latest edition, or Canadian
Electrical Code Part 1-CSA Standard C22.1 and
local building/electric codes, using copper
conductors only.
(ALTERNATE) REMOTE DEHUMIDISTAT
The dehumidifier is supplied with its own, self
contained, dehumidistat control which includes an
air sampling sequence; however, the unit can also
be controlled by a remote dehumidistat located in
a conditioned space. DO NOT LOCATE THE
DEHUMIDISTAT IN THE DUCTWORK. It is
recommended that the remote dehumidistat, if
used, be located in an area close to the air
conditioner thermostat, out of drafts, away from
heat sources, and out of direct sunlight. It should
be located approximately 5 feet above the floor in
an area with good air circulation at average
temperature and relative humidity.
Remove the jumper on terminals S1 and S2 and
connect the remote dehumidistat as shown on the
unit connection diagram.
INSTALLATION OPTIONS
The dehumidifier can be connected so that the dehumidifier and the central air
conditioner fan operate totally independent of each other (independent
operation) or it can be connected in such a manner as to require that the
dehumidifier and the central fan operate simultaneously (dependent operation).
