Before installation
WARNING
•Do not alter the unit or disassemble it more than necessary.
(Fire, electric shock or injury may result.)
•Do not install the unit in a bathroom or other highly humid location.
(Fire or electric shock may result.)
•Use the unit at the rated voltage and within the control capacity range.
(Failure to do so may result in fire or electric shock.)
•Make sure the outside air intake opening is positioned so that it will not take in
combustion gases or other exhaust. Position the unit so that it will not become covered
with snow. (If intake air is not fresh, oxygen may become depleted in the room.)
•Install the unit securely to a sufficiently strong wall surface.
(Injuries may result if the unit falls.)
•Install the unit only on a wall. Do not install it on a ceiling.
(Injuries could result if the unit falls.)
•Do not install the unit in excessively hot areas, areas of oily smoke, or near open flames
(Fire may result).
•Wear gloves when attaching the unit (or injury may result).
•Attach the unit so that the air supply/exhaust pipes slope downward toward outdoors.
(Rainwater entering the unit could cause electric shock or fire, or wet indoor items.)
•Install the supplied outdoor weather covers.
(Rainwater entering the unit could cause electric shock or fire, or wet indoor items.)
•After installation, be sure to remove the power plug from the wall outlet when not using
the unit for an extended period. (Failure to do so could cause insulation deterioration, resulting in
electric shock or fire from a short-circuit.)

2. Screw the extension pipes all the way into the
extension joints, making sure they fit securely.
3. Cut the pipes to a length of [wall thickness] + 30 mm.
Before screwing the extension joints into
the pipes, apply caulking (commercially
available) to the O-rings on the joints (to
prevent condensation inside the pipes
wetting the indoor wall).
Secure mounting plate.
•Secure the mounting plate to the wall (using seven
wood screws and the single screw for loose
attachment).
•You can align the plate horizontally by suspending
a weight from the top and aligning its string with the
center line.
•Be sure to secure the mounting plate with the two
screws near the catches, and with screws in
symmetrical positions.
•To attach the plate to a concrete wall, use concrete
screws to secure it (commercially available).
