Indoor/Outdoor Unit 

Installation Drawings

For installation of the indoor units, refer to the installation manual which was provided with the units.
(The diagram shows a wall-mounted indoor unit.)

 CAUTION

• Do not connect the embedded branch piping and the outdoor unit when only carrying out piping work without connecting the 

indoor unit in order to add another indoor unit later.
Make sure no dirt or moisture gets into either side of the embedded branch piping.
See “7 Refrigerant piping work” on page 9 for details.

• It is impossible to connect the indoor unit for one room only. 

Be sure to connect at least 2 rooms

with putty. 

Cut thermal insulation 
pipe to an appropriate 
length and wrap it with 
tape, making sure that no 
gap is left in the insulation 
pipe’s cut line.

Wrap the insulation 
pipe with the finishing 
tape from bottom to top.

250mm from wall

Allow space for piping 
and electrical servicing.

If there is the danger of the unit falling 
or overturning, fix the unit with 
foundation bolts, or with wire or other 
means.

If the location does not have good 
drainage, place the unit on a level 
mounting base (or a plastic pedestal). 
Install the outdoor unit in a level 
position. Failure to do so may result in 
water leakage or accumulation.
