Indoor Unit Installation

3.
Inter-unit wiring.
1) Open the front panel, then remove the service lid.
2) Pass the inter-unit wiring from the outdoor unit through the
feed-through wall hole and then through the back of the indoor
unit. Pull them through the front side. Bend the ends of tie
wires upward for easier work in advance. (If the inter-unit
wiring ends are to be stripped first, bundle wire ends with
adhesive tape.)
3) Press the bottom frame of the indoor unit with both hands to
set it on the mounting plate hooks. Make sure the wires do not
catch on the edge of the indoor unit.
4.
Humidifying hose installation work.
CAUTION
• Be sure to use humidifying hose sold as optional accessory. (KPMH996A10S (10m set), KPMH996A15S (15m set))
1) The length of the humidifying hose needs to be set to ensure humidifying capacity. Cut off any excess hose.
Use the remote controller to set the hose length. (Refer to page 13.)
• Attach a cover to the end of each humidifying hose so that no moisture or foreign substance will go into the hose when
leaving the hose without being connected to the outdoor and indoor units.
• When laying the humidifying hose inside the wall, block the ends of the humidifying hose with tape or the like to prevent
water or anything else from entering it until it is connected to the indoor unit and outdoor unit ducts.
• Do not bend the humidifying hose more than 90°.
• Use caution not to deform the cuff while installing the humidifying hose.
