Electrical Requirements - Trane EDHUM098 Installation & Operation Instructions

The Dehumidifier plugs into a common grounded 115 VAC outlet. Locate the dehumidifier in an area where the
cord's length (9') easily reaches a 115 VAC electrical outlet with a minimum of 15 Amp circuit capacity. If used
in an area that may become wet, a GFCI protected circuit is recommended. Consult local electrical codes for
further information.
A variety of control devices can be used with this dehumidifier. The control is to be located remotely from the
dehumidifier and placed in the space to be conditioned. A low voltage (24 Volt) control MUST be used with the
Dehumidifier and MUST be connected with low voltage (18-22 gauge) thermostat wire.
WARNING! WARNING!
THE REMOTE CONTROLS OF THE DEHUMIDIFIER ARE POWERED BY A LOW VOLTAGE CIRCUIT (24
VAC) AND MUST NEVER CONTACT OR BE CONNECTED TO A HIGH VOLTAGE CIRCUIT.
CAUTION! CAUTION!
DO NOT ALLOW THE 24V TERMINAL TO CONTACT THE COM/DMPR TERMINALS ON THE
DEHUMIDIFIER OR DAMAGE TO THE TRANSFORMER WILL RESULT.
CAUTION! CAUTION!
SOME OF THE SCREW TERMINALS ON THE DEHUMIDIFIER MAY NOT BE USED WITH CERTAIN
CONTROLS AND SHOULD BE LEFT UNCONNECTED.
Electrical Precautions
• Do not install the control where it may not accurately sense the relative humidity such as near HVAC
supply registers, near exterior doors, on an outside wall, near a window, or near a water source.
• The screw terminals on the Dehumidifier and the control are labeled to prevent confusion.
• Be sure to consult the electrical schematic in the CONTROLS Section (page 12) of this manual or inside
the access panel of the Dehumidifier before making control connections.
