9-1-4. Installation/Servicing Tools
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)

• 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.

Changes in the product and components
Changes
As pressure is high, it is impossible to measure by means of
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
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.
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
occur.
The size of opposite sides of flare nuts have been increased. Incidentally,
a common wrench is used for nominal diameters 1/4 and 3/8.
By increasing the clamp bar's receiving hole, strength of spring in the
tool has been improved.
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
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.

outdoor side.
NOTE
• When drilling the wall that contains a metal lath,

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.
