9-2. Indoor Unit

9-2-1. Installation Place

•A place which provides the spaces around the indoor unit as shown in the above diagram.

•A place where there is no obstacle near the air inlet and outlet.

•A place which allows an easy installation of the piping to the outdoor unit.

•A place which allows the front panel to be opened.

CAUTION

Mounting the Installation Plate

For installation of the indoor unit, use the paper pattern on the back.

9-1-4. Installation/Servicing Tools	Changes in the product and components

In the case of an air conditioner using R410A, in order to prevent any other refrigerant from being charged accidentally, to service port diameter of the outdoor unit control valve (3 way valve) has been changed. (1/2 UNF 20 threads per inch)

•In order to increase the pressure resisting strength of the refrigerant piping flare processing diameter and size of opposite side of flare nuts has been changed.

(for copper pipes with nominal dimensions 1/2 and 5/8)

New tools for R410A

New tools for R410A	Applicable to R22 model	Changes
	⋅	As pressure is high, it is impossible to measure by means of
Gauge manifold		conventional gauge. In order to prevent any other refrigerant from
		being charged, each port diameter has been changed.
	⋅	In order to increase pressure resisting strength, hose materials and
Charge hose		port size have been changed (to 1/2 UNF 20 threads per inch).
		When purchasing a charge hose, be sure to confirm the port size.
Electronic balance	¡	As pressure is high and gasification speed is fast, it is difficult to read
		the indicated value by means of charging cylinder, as air bubbles
for refrigerant charging
		occur.
Torque wrench	⋅	The size of opposite sides of flare nuts have been increased. Incidentally,
(nominal diam. 1/2, 5/8)		a common wrench is used for nominal diameters 1/4 and 3/8.
Flare tool (clutch type)	¡	By increasing the clamp bar’s receiving hole, strength of spring in the
		tool has been improved.
Gauge for projection adjustment	——	Used when flare is made by using conventional flare tool.
		Connected to conventional vacuum pump. It is necessary to use an
		adapter to prevent vacuum pump oil from flowing back to the charge
Vacuum pump adapter	¡	hose. The charge hose connecting part has two ports-one for
		conventional refrigerant (7/16 UNF 20 threads per inch) and one for
	⋅	R410A. If the vacuum pump oil (mineral) mixes with R410A a sludge
		may occur and damage the equipment.
Gas leakage detector		Exclusive for HFC refrigerant.
		Exclusive for HFC refrigerant.

•Incidentally, the “refrigerant cylinder” comes with the refrigerant designation (R410A) and protector coating in the U. S’s ARI specified rose color (ARI color code: PMS 507).

•Also, the “charge port and packing for refrigerant cylinder” require 1/2 UNF 20 threads per inch correspond- ing to the charge hose’s port size.

•Direct sunlight to the indoor unit wireless receiver should be avoided.

•The microprocessor in the indoor unit should not be too close to r-f noise sources.

(For details, see the owner's manual.)

Remote controller

•A place where there are no obstacles such as a curtain that may block the signal from the indoor unit.

•Do not install the remote controller in a place exposed to direct sunlight or close to a heating source, such as a stove.

•Keep the remote controller at least 1 m apart from the nearest TV set or stereo equipment.

(This is necessary to prevent image disturbances or noise interference.)

•The location of the remote controller should be determined as shown below.

Cutting a Hole

When install the refrigerant pipes from the rear.

The center of the piping slot is above the arrow.

The center of the pipe

hole is above the arrow.

1. After determining the pipe hole position on the mounting plate (80 mm ), drill the pipe hole (ø 65 mm) at a slight downward slant to the outdoor side.

NOTE

•When drilling the wall that contains a metal lath, wire lath or metal plate, be sure to use a pipe

hole brim ring sold separately.

Fig. 9-2-3

When the installation plate is directly mounted on the wall

1.Securely fit the installation plate onto the wall by screwing it in the upper and lower parts to hook up the indoor unit.

2.To mount the installation plate on a concrete wall with anchor bolts, utilize the anchor bolt holes as illustrated in the above figure.

3.Install the installation plate horizontally in the wall.

CAUTION

When installing the installation plate with mounting screw, do not use the anchor bolt hole. Otherwise the unit may fall down and result in personal injury and property damage.

CAUTION

Failure to firmly install the unit may result in personal injury and property damage if the unit falls.

•In case of block, brick, concrete or similar type walls, make 5 mm dia. holes in the wall.

•Insert clip anchors for appropriate U mounting screws.

NOTE

•Install the installation plate using 4 to 6 pieces of mounting screw securing four corners with screws.
