Take into consideration the following contents when creating the blueprint. 
■ Indoor unit installation location 

  Do not install the unit in excessive oil fume area such as kitchen, workshop and etc. 

  The location should be strong enough to support the main unit without vibration. 

  There should not be any heat or steam source nearby. 

  Drainage should be easy. Avoid locating the drain port close to ditches (domestic wastewater). 

  Avoid locations above entrances and exits. 

  Do not block the air intake and discharge passages. 

  Select the location that enables the cool and warm air to spread out to the entire room. 

  Locate the indoor unit at least 1 m or more away from a TV, radio, wireless appliance, antenna cable and 

fluorescent light, and 2 m or more away from a telephone. 

 
 

 

Install the remote controller cable at least 5 cm away from 
electric wires of other appliances to avoid miss-operation 
(electromagnectic noise). 

 

 

 
■ Remote control mounting location 

  Allow sufficient space around the remote 

controller   as shown in the illustration at right. 

  Install in a place which is away from direct sunlight 

and high humidity. 

  Install in a flat surface to avoid warping of the 

remote controller. If installed to a wall with an 
uneven surface, damage to the LCD case or 
operation problems may result. 

  Install in a place where the LCD can be easily 

seen for operation. 
(Standard height from the floor is 1.2 to 1.5 
meters.) 

  Avoid installing the remote controller cable near 

refrigerant pipes or drain pipes, else it will cause 
electrical shock or fire. 

 

 

 

1  Insert the piping sleeve to the hole. 
2  Fix the bushing to the sleeve. 
3  Cut the sleeve until it extrudes about 15 mm 

from the wall. 

 

 

When the wall is hollow, be sure to use the sleeve for tube 
assembly to prevent pests from damaging the cables, e.g. 
mice biting the connection cable. 

 

4  Finish by sealing the sleeve with putty or 

caulking compound at the final stage.

  Always provide sufficient entry and exit space to allow installation work, inspection and unit replacement. 

  Waterproof the rear surface of the ceiling below the unit in consideration of water droplets forming and dropping. 

 

 

When cooling operation is performed for an extended period under the following conditions, water droplets may form and drop. Attach locally 
purchased insulation (foamed polyethylene with a thickness of 5 mm or more) to the outside of the indoor unit before installing into the ceiling 
to improve heat insulation. 

  Locations with a dew point inside the ceiling of 23°C or more. 

  Kitchens and other locations that produce large amounts of heat and steam. 

  Locations where the inside of the ceiling serves as an outside air intake passage. 

 

  When installing into a ceiling, select the unit position and airflow direction that enable the cool and warm 

  Do not place objects that might obstruct the airflow within 1 m below the intake grill. 

 

  The relative positions of the ceiling opening and 

hanging bolts are shown in the illustrations below. 
When making an inspection opening below the 
unit, make a 960 mm x 480 mm opening at the 
ceiling surface. Also, lead the drain piping, 
refrigerant piping and indoor/outdoor connection 
cables up to the respective piping and cable 
connection positions. 

  Secure the hanging bolts (M10, locally purchased) 

firmly in a manner capable of supporting the unit 
weight. 

 

 

  Consult your construction or interior contractor for details on finishing the ceiling opening.

  Fit the drain hose insulation   around the drain hose as shown in the diagram beside. 

  Attach the discharge chamber. () (10 screws) 

  Cut out the intake cut-out portions at the unit rear panel using a cutter or other tools to make openings. 

  Remove the two screws at the rear edge of the unit top panel and attach the intake chamber. () (8 screws) 

 

 

 

 

 

 

  To increase the air volume, open the control box and on the control board, switch the FAN switch (SW2) to “HI”. 

  See the diagram for “Connecting the Indoor/Outdoor Connection Cable”. 

 

  Attach the nuts and washers to the hanging bolts, then lift up and hook the main unit onto the hanging fixtures. 

  Check if the unit is leveled using a level or a vinyl hose filled partially with water.

1  Remove the remote controller   lower case. 

(Insert a flat-tipped screw driver or similar tool 
2 to 3 mm into one of the gaps at the bottom 
of the case, and twist to open. Refer to the 
illustration at right.) 
Be careful not to damage the lower case. 

2  Do not remove the protective tape which is 

affixed to the upper case circuit board when 
remove the remote controller lower case. 

3  Secure the lower case to an outlet box or wall. 

Refer to (A) or (B) instructions below 
depending on your choice of cable installation. 

4  Be sure to use only the screws provided. 
5  Do not over tighten the screws, as it may 

result in damage to the lower case. 

 

 

 
 
 
 
 

6  Connect the indoor unit and the remote controller   as shown in the illustration at below. 
7  Insert firmly the connector of remote controller cable   to connector at control box of indoor unit. 
8  Fix the green wire from remote controller cable   to the grounding location provided. 

 

 

 

1  Embed an outlet box (JIS C 8336) into the wall. Outlet box maybe purchased separately. Medium size 

square outlet box (obtain locally) Part No. DS3744 (Panasonic Co., Ltd.) or equivalent. 

2  Secure the remote controller lower case to the outlet box with the two accessory screws  . Make sure that 

the lower case is flat against the wall at this time, with no bending. 

3  Pass the remote controller cable   into the box. 
4  Route the remote controller cable   inside the lower case through rear feeding-out direction. 
5  Insert firmly the connector of remote controller cable   to connector (CON1) in the upper case circuit board. 

(Refer to the illustration at below.) 

6  Secure the remote controller upper case to the lower case with the tabs provided. 

 

 

When the wall is hollow, please be sure to use the sleeve for remote controller cable to prevent dangers caused by mice biting the cable.
