ART COOL MIRROR INDOOR UNITS
Installation and Best Layout Practices
Hanging the Indoor Unit Frame
1. Attach the three (3) hooks on the top of the indoor unit to the top edge of
the installation plate. Verify the hooks are properly attached to the instal-
lation plate by gently shaking the indoor unit from side to side.
2. Unlock the tubing clamp from the indoor unit frame. For easier access be-
tween the bottom of the indoor unit and the wall, prop the clamp between
the indoor unit frame and installation plate.
3. Remove the screw covers at the bottom of the indoor unit, unscrew the
two (2) screws, remove the frame cover, remove the piping connection
cover, and position the piping for installation (down, back, left, or right).
Preparing for Installation
Prepare the refrigerant piping and drain hose (indoor unit piping) for installation through the wall:
press on the top of the tubing clamp and slowly guide the piping / hose down (depending on instal-
lation requirements, then to the left or right). Relock the tubing clamp after the piping / hose are
released.
Do not bend the piping / drain hose from side to side, it may damage the components.
