Installing the indoor unit
Attaching the duct connector
Attach 4 duct connectors to the unit using the six screws supplied for each connector.
Attaching the washers and nuts
1
Procure the hanging bolts, nuts, and washers locally.
2
Attach the washers and nuts to the hanging bolt (M12) as shown in the figure on the right.
Fixing the unit
1
Fit the hanging bracket on the hanging bolt, then adjust the position of the unit so that it is level.
2
Tighten the bolts securely using a double nut to prevent the bolts from becoming loose.
• If the bolts are not tightened securely, the unit will vibrate and an accident may occur.
• Tighten the bolts so that they can bear the weight of the unit.
3
Confirm that the unit is installed level.
• Confirm that the unit is installed level or is inclined within 1°(downward) against the drain outlet using a spirit
level.
• Do not set the unit inclined (upward) against the drain outlet; otherwise, water will leak from the unit.
CAUTION
To preventing vibration, use vibration proof hanging brackets (locally procured).
