(2.4 m) above floor or grade level.

11.1.2 Outdoor Unit

 If an awning is built over the unit to prevent direct

sunlight or rain, be careful that heat radiation from
the condenser is not obstructed.

 There should not be any animal or plant which

could be affected by hot air discharged.

 Keep the spaces indicated by arrows from wall,

ceiling, fence or other obstacles.

 Do not place any obstacles which may cause a

short circuit of the discharged air.

 If piping length is over the [piping length for

additional gas], additional refrigerant should be
added as shown in the table.

 Recommended installation height for outdoor unit

should be above the seasonal snow level.

Example: For XE9PKUA
If the unit is installed at 32.8 ft (10 m) distance, the
quantity of additional refrigerant should be 1.64 oz (50

g) .... (32.8 - 24.6) ft x 0.2 oz/ft = 1.64 oz. ((10-7.5) m

1 Mount the installation plate on the wall with 5 screws or more (at least 5 screws).

(If mounting the unit on the concrete wall, consider using anchor bolts.)
o Always mount the installation plate horizontally by aligning the marking-off line with the thread and using

a level gauge.

2 Drill the piping plate hole with ø2-3/4" (ø70 mm) hole-core drill.

o Line according to the left and right side of the installation plate. The meeting point of the extended line is

the center of the hole. Another method is by putting measuring tape at position as shown in the diagram
above. The hole center is obtained by measuring the distance namely 5-1/16" (128 mm) for left and right
hole respectively.

o Drill the piping hole at either the right or the left and the hole should be slightly slanting to the outdoor

side.

11.2.1 To Drill a Hole in the Wall and
Install a Sleeve of Piping

1 Insert the piping sleeve to the hole.
2 Fix the bushing to the sleeve.
3 Cut the sleeve until it extrudes about 19/32"

(15 mm) from the wall.

CAUTION

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

4 Finish by sealing the sleeve with putty or

caulking compound at the final stage.
