Stand Alone Installation

In a free standing installation, the dehumidifier pulls air from the installed space and returns the dehumidified air back to that space.

•Place unit in area with drain access and within 8’ of a dedicated outlet.

•Unit can also be ducted to pull and return to a single living space.

See Figure 8.

Leveling

The feet can be adjusted to level the unit and/or to accommodate a p-trap. Leveling is required to ensure proper drainage from the dehumidifier.

•Minimum unit height (feet fully retracted): 2.5”

•Maximum unit height (feet fully extended): 5.75”

WIRING

Wiring To HVAC System

The dehumidifier can be wired to activate the HVAC blower during dehumidification. This is recommended because it offers better circulation and balancing of the indoor air conditions. Note: Running the HVAC blower during dehumidification does not affect moisture removal efficiency. If the unit is not wired to the HVAC system, air is pulled through the unit, dehumidified, and circulated solely by the dehumidifier blower.

HVAC Wiring Instructions

1.Disconnect power to the HVAC system using disconnect switch or fuse/breaker.

2.Unplug the dehumidifier.

3.Remove wiring access panel on the dehumidifier outlet panel.

4.Run a 3-wire cable from the dehumidifier to the furnace/air handler.

5.Unplug the G-STAT, R-HVAC, & G-HVAC terminals. Make the connections shown in Figure 9.

6.Plug terminals back into circuit board.

7.Replace the wiring access panel when wiring is complete.
