Before Getting Started
Your Koldfront though the wall air conditioner is designed to be installed in conjunction with a wall
sleeve. If you are installing your new Koldfront air conditioner into an existing wall sleeve, please
check to confirm that the wall sleeve is in sound structural condition and that is sized
appropriately to accommodate your Koldfront air conditioner. For reference, your new Koldfront
Air Conditioner is 24 1/4" x 20 3/8”x 14 1/2”
Note: When choosing your installation location make sure power supply cord is within 4 feet of a
grounded 3-prong outlet.
Important: When installation is complete, the unit MUST have a rearward slope as shown in the
image below to ensure proper drainage. This is accomplished by using the Tapered Support
Blocks as noted in the “Attach Seals” section of this document.

6
Note: The Koldfront Through the Wall Air Conditioner Sleeve (Model: WTCSLV) is designed
specifically for Koldfront’s line of through the wall air conditioners and makes installation simpler
than using non-Koldfront branded sleeves. The WTCSLV can be purchased from an authorized
retailer or the dealer from which you purchased your Koldfront air conditioner.
Preparing the Wall Sleeve
Your Koldfront Through The Wall Air Conditioner unit is intended to be installed into a compatible
wall sleeve enclosure. A wall sleeve provides the proper support and enclosure for your air
conditioner and allows for the wall opening to be properly sealed prior to final installation.
To properly install your new Koldfront Through The Wall Air Conditioner into a wall sleeve, it is
required that you use the Rear Louver Panel / Grille that was shipped with your new air
conditioning unit. This will ensure proper air flow from the back of the unit. If your installation
utilizes a previously installed wall sleeve, please replace the Rear Louver Panel / Grille with the
one provided with your new air conditioner.
Attach Seals and Support Blocks to Wall Sleeve
With the wall sleeve properly assembled, it is now time to prepare the wall sleeve enclosure
for the air conditioner unit. The process involves positioning seals and foam support blocks
inside of the wall sleeve enclosure in order to enable a proper fit for the air conditioning unit.
Important: The below instructions are to be used in conjunction with the Koldfront Wall Sleeve
model WTCSLV. Instructions for other compatible wall sleeves can be found in the “Alternate
and Supplemental Installation Instructions” section.

Prepare Ground Wire
To properly ground the air conditioner unit, the ground wire must be secured to the frame of the
wall sleeve. When the air conditioner unit is placed inside of the wall sleeve, this ground wire will
be attached to the air conditioner frame to allow for proper grounding of the air conditioner unit.
1. Locate the following parts:
•Grounding Screw (1)
•Toothed Grounding Screw Washer
•Ground Wire
2. As needed, use a drill and 1/8” bit to drill a hole for the grounding screw. The hole needs to be
approximately 1” from the bottom and 3” from the front edge of the wall sleeve on the left side.
3. Attach one end of ground wire using 1 (one) Toothed Washer and 1 (one) Grounding Screw.
Note: This step may require the use of a drill with a 1/8” drill bit. If your wall sleeve has been
previously installed, there may be no requirement to drill a new hole for the grounding screw. If
using the Koldfront wall sleeve (model WTCSLV), the hole should be pre-drilled for you.
Also, please note that additional fastener types may have been included and may be used to suit
your particular installation setup.

9
Install Air Conditioner Unit into Wall Sleeve
With the wall sleeve fully prepared, you are now ready to insert the air conditioner unit into the
wall sleeve. Two or more people may be required for this step.
1. Remove the CENTER cabinet screw on the left lower side of the air conditioner cabinet. Set
aside and / or discard the plastic washer.
2. The ground wire will be attached to the air conditioner cabinet using the screw you just
removed along with a Toothed Washer.
3. Gently slide the air conditioner cabinet into the Wall Sleeve. With the cabinet screw hole still
exposed, attach the ground wire to the cabinet using the cabinet screw making sure that the
Toothed Grounding Screw Washer is pressed against the cabinet.

10
4. Slide air conditioner completely to the rear of the wall sleeve unit ensuring that all seals and
foam support blocks create snug fit for the unit. Please be sure that the ground wire does not
become entangled when the unit is pushed back into the wall sleeve.
Completing Installation
With the air conditioner installed into the Wall Sleeve and the ground wire properly attached, it is
time to complete installation by inserting the Main Insulating Seal (stuffer seal) and attaching the
Trim Frame.
1. Locate the Main Insulating Seal (stuffer seal) included with the installation kit. This is the
longest seal and measures 1” X 11/2” X 84”. Using a putty knife or flathead screwdriver, insert
the seal into the gap between the air conditioner cabinet and the Wall Sleeve frame. Trim seal
as needed.
2. Locate the 4 (four) trim kit components that were packaged with your installation kit. Snap the
pieces together as shown in the image below.

11
3. Pull the power cord through the Trim Kit frame and then slide the Trim Kit Frame over the unit
until it is flush with the wall.

To choose the operating mode press Mode . Each time you press the button a mode is
selected in a sequence that goes from Auto, Cool, Heat, Dry, to Fan. The indicator light
beside the mode button will be illuminated and remain on once the mode is selected.
To Operate in Cool Mode:
•When the unit is set to “Cool” mode it will cool the room to maintain the desired set
temperature.
•When the desired temperature has been reached, the unit will automatically maintain the
temperature.
•Press the Up and Down buttons to adjust the desired temperature and press the Fan
button to adjust the fan speed.
•The “Cool” mode has an automatic 3 minute delay if the unit it turned off and on quickly
to prevent overheating of the compressor and possible circuit breaker tripping. The fan
will continue to run during this time.
To Operate in Heat Mode:
•When the unit is set to “Heat” mode it will heat the room to maintain the desired set
temperature.
•When the desired temperature has been reached, the unit will automatically maintain the
temperature.
•The Fan speed is not adjustable in heat mode.

AUTO Mode is a setting that allows the unit to automatically switch between COOL, FAN and
HEAT in order to achieve and maintain the desired set temperature.
•When set to “Auto” mode, the unit will automatically select cooling, heating or fan only
operation depending on the temperature selected and the current room temperature.
•Once the temperature you selected is achieved the unit will automatically maintain the
room temperature by switching between modes as needed.
•While in AUTO Mode, the fan speed cannot be adjusted manually.
•When operating in AUTO MODE, the control panel display will NOT illuminate to indicate
any change between Cool/Fan/Heat. The AUTO indicator will remain illuminated.
Note: Heat function is intended to provide supplemental heating in addition to an existing heat source. The
heat function has a lower BTU rating than the cool mode and therefore does not treat the same square
footage. The maximum heating capacity of the unit is 15°F above the ambient room temperature.
Note: The unit’s temperature sensor is located on the front of the unit near the air intake port. As such, a
temperature reading taken manually on the opposite side of the room may read differently than what the
unit is detecting. Please make note of this when operating your unit.
Also, the unit does not constantly take temperature readings. The unit will take a temperature reading
periodically while operating in AUTO mode, or immediately upon adjustment of the desired set
temperature. As such, it is important to understand that when operating in AUTO MODE the unit may not
switch between Cooling, Heating, and Fan Mode at the exact moment when a temperature change occurs.

16
To Operate in Fan Only:
•Use this function only when cooling is not desired, such as for room air circulation. You
can choose any speed you prefer.
•During this function the display will show the actual room temperature as in the cooling
mode.
•In Fan Only mode, the temperature is not adjusted.
To Operate in Dry Mode:
•In this mode, the air conditioner will operate as a dehumidifier. Because the conditioned
space is closed or sealed, some degree of cooling will continue to occur.
To Use the Energy Saver Feature:
To start the Energy Saver feature, press the Energy Saver button. This feature is
available on “Cool”, “Dry”, and “Auto”. The fan continues to run for 3 minutes after the
compressor shuts off. The fan then cycles on for 2 minutes at 10 minute intervals until the
room temperature is above the set temperature, at which point the compressor turns back on
and cooling starts.
To Use the Sleep Feature:
To initiate, press the Sleep button. In this mode the selected temperature will increase
(cooling) or decrease (heating) by 2°F (1°C) 30 minutes after the mode is selected. The
