INTRODUCTION
Thank you for purchasing the Hotpoint MAC140 Portable Air Conditioner. This unit is designed to improve
indoor living and working comfort by providing cooling, dehumidifying, and ventilation with minimal
installation.
This multi-functional unit operates as an air conditioner, dehumidifier, and fan. Unlike traditional portables,
there is no bucket to empty. The condensate water is evaporated and removed through the exhaust duct along
with the warm exhaust air. When operating as an air conditioner, this unit is designed for spot cooling or
cooling a room no larger than 550 square feet with a standard eight foot ceiling height. When using this
appliance, always exercise basic safety precautions.
Other air conditioning methods are recommended when the indoor temperature is either below 64°F or above
86°F.
Please complete the following information for future reference. Retain this owner’s manual with your sales
receipt as a permanent record of your purchase.

INSTALLATION
SELECTING THE LOCATION
Place the unit in a flatlocation where the air
outlets are not obstructed. Place the unit at
least 20” (50cm) away from awall or other
obstacle.
MOUNTING THE EXHAUST HOSE
Slide the square end of the exhaust duct over
the hot air outlet on the back of the unit.
The exhaust hose should be kept as short and
straight as possible. Prevent any sharp bends in
the exhaust hose, as this will trap hot exhaust
air.
The hot exhaust air can be vented through the
wall or out a window. If mounting in the wall, the
height of the hole should be 16 to 50 inches
(40cm to 130cm).

WINDOW KIT INSTALLATION
The window kit is designed to fit into most
standard vertical and horizontal windows, as well
as some sliding glass doors. However, it may be
necessary to modify someaspects of the
installation process for certain window types.
1. Open the window or sliding door and adjust
the length of the window kit to fit the
opening. If the window kit is not long
enough, connect the extra window kit panel
to fit the opening. Mark and cut down a
single panel of the window kit if necessary.
2. Place the window kit between the window
and the window frame as shown in the
images to the right. Close the window onto
the window kit to form a tight seal.
3. Attach the exhaust duct adapter to the
window kit. Tabs located on the adapter will
lock into place securing the adapter to the
window kit.
