Warranty Information

•The IW-25-2 Dehumidifier must always be connected using a grounded electrical connec-
tion (as required for all electrical appliances). If non-grounded wiring is used, all liability re-
verts to owner and the warranty is voided.
•The IW-25-2 Dehumidifier should only be installed and serviced by a qualified technician.
•If there is a chance that water flooded the dehumidifier, it should be opened and allowed
to dry thoroughly before reconnecting to electrical power and restarting.
•To ensure proper operation, no obstruction should be located within 36” of the discharge
of the unit.
•Do not insert any objects or fingers into the inlet or discharge. If service is required, call a
qualified technician.
•All work on the dehumidifier should be done with the unit “off” and unplugged or the
breaker turned off.
•Do not use water to clean the exterior. To clean unit, unplug from power, then use a damp
cloth to wipe exterior.
•Drain hose must be installed to ensure proper gravity flow of condensate water to a drain
source

Safety Notes

Identification!
For future reference, write down the model, serial number, and date of purchase for your dehumidifier.
This is extremely helpful if you need to seek assistance in the future. The data label on the side of your
unit has key characteristics of your specific unit.
Model Number: IW-25-2
Serial Number: Date of Purchase:
For additional questions concerning your dehumidifier, the following options are available:
•Contact your installing contractor

Electrical Supply
Power Supply: 115 V, 60 Hz AC, Single Phase
Outlet Requirement: 3-Prong, GFI
Circuit Protector: 15 Amp Time Delay Fuse or Circuit Breaker
WARNING: 115 Volts AC may cause serious injury from electric shock.
To ensure safety:
1. 1. Disconnect electrical power before servicing
2. 2. Only plug unit into grounded electrical circuit
3. 3. Do not use extension cord
4. 4. Do not use a plug adapter.
Principle of Operation
#The IW-25-2 Dehumidifier utilizes its integral humidistat to monitor the conditioned space. When
the relative humidity goes above the selected set point, the dehumidifier will energize. Air is drawn
across an evaporator coil, which is cooler than the dew point of air. This means moisture will condense
out of the air. The air is then reheated through the condenser coil and distributed back into the room.

Installation
Mounting:
The IW-25-1 Dehumidifier is designed to mount into the wall cavity between two studs mounted
on standard 16” centers. The chassis of the unit slips into the wall from the front and is secured by
the four mounting tabs with screws provided by others. Blocking is REQUIRED under the
bottom of the cabinet before screwing to the wall.
Plumbing:
The 10’ drain line (included) is to be attached to the barbed drain hose connection on the rear of
the unit. The entire length of drain line to the gravity drain must be downhill. No low spots or
dips are permitted as they may cause leaks. It is possible to use a short piece of included tube
to deposit condensate directly into a PVC gravity drain system. All state and local plumbing
codes must be adhered to for proper operation of the unit and maintain warranty
compliance.

Installation
#WARNING: Do not install your dehumidifier in a corrosive environment.
Mounting:
The IW-25-2 Dehumidifier is designed to mount into the wall cavity between two studs
mounted on standard 16” centers. The chasis of the unit slips into the wall from the front
and is secured by the four mounting tabs with screws (not provided). Ensure the bottom
of the unit is properly supported before screwing into drywall.
Plumbing:
The 10’ drain line (included) is to be attached to the barbed drain hose connection on the
rear of the unit. Secure hose with a hose clamp (included). The entire length of drain line to
the gravity drain must be downhill. No low spots or dip are permitted as they may
cause leaks. It is possible to use a short piece of the included tube to deposit condensate
directly into a PVC gravity drain system. All state and local plumbing codes must be ad-
hered to for proper operation of the unit and to maintain warranty compliance.
Optional Condensate Pump:
If desired, condensate from the unit can be drained into a remote condensate pump (provided in end-
use). If the condensate pump has a normally open safety switch, the safety switch can be connected to
the dehumidifier. This will allow the safety switch to shut offthe dehumidifier if it detects a problem. The
wiring connections for the remote condensate pump are located on the left hand side of the electrical
compartment on the back of the dehumidifier. Connect the red and black wires on the dehumidifier to
the Normally Open Pump Safety switch.
Electrical:
A 10’ power cord is provided for use with a standard grounded outlet. It is also possible to
hard wire the unit, if necessary. Simply remove the electrical cover plate from the back of
the unit, remove the cord, and connect the hard wiring. All state and national electrical
codes must be adhered to for proper unit operation and warranty compliance.

Unit Operation
1. ON/OFF Control
Plug the unit in and the display will show the current room relative humidity. Press the
on/off button, the machine will beep twice indicating it is ready for automatic service. If
the humidity is below setpoint, it will remain in standby condition. If the humidity is
above setpoint, unit will turn on and begin to remove moisture from the room.
Press the on/off button again, and a single beep will be your indication that you’ve taken
the unit offline. No room conditioning will occur until you turn the unit on.
2. Setting the Humidity Level
Press the button to set indoor humidity. The humidity display will shift from
displaying the actual room humidity level to the current setpoint. The humidity can be set in 5%
increments from 30-90%. Pressing the SET button increases the setpoint by 5% unit you reach 90%
and then it sequence back to 30% and increases from there.
