cord (Design H07 RN-F), or cord designation 245 IEC 66. (2.5 mm² or more)
UK PLUGS AND SOCKETS ETC (SAFETY) REGULATIONS 1994, SI NUMBER 1768
With regard to Schedule 3, item 7 of the above UK Regulations, this appliance must be permanently connected
to the fixed wiring of the main electrical supply by means other than the use of an approved 13 Amp plug-top as
outlined in the Regulations.
Electrical work must be carried by suitably qualified persons and in accordance with all relevant safety standards and codes of practice.
We recommend that the power supply for this appliance is derived from a suitably protected dedicated circuit.
(for U.K. only)
CAUTION
• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DESTROY
OZONE LAYER.
R410A refrigerant is apt to be affected by impurity such as water, oxidizing membrane, and oils because pressure of R410A refrigerant is approx. 1.6 times of refrigerant R22. Accompanied with adoption of the new refrigerant, refrigerating machine oil has been also changed. Therefore, during installation work, be sure that water,
dust, former refrigerant, or refrigerating machine oil does not enter into the refrigerating cycle of new-refrigerant
air conditioner.
To prevent mixing of refrigerant or refrigerating machine oil, the sizes of connecting sections of charging port of
the main unit or installation tools are different from those for the conventional refrigerant. Accordingly, the
exclusiv e tools are required for the new refrigerant (R410A) as shown below.
For connecting pipes, use ne w and clean piping materials with high pressure-tight force, which were made for
R410A only, so that water or dust does not enter. Moreover, do not use the existing piping because there are
problems about pressure-tight force and inner impurity in the existing piping.
CAUTION
This appliance must be connected to the mains by means of a switch with a contact separation of at least 3 mm.
The installation fuse (25A D type ) must be used for the power supply line of this air conditioner.
DANGER
• FOR ELECTRICAL WORKS THE WIRING AND CABLES MUST BE PERFORMED IN COMPLIANCE WITH
NATIONAL WIRING STANDARD OR REGULATION.
IF INCORRECT AND INCOMPLETE WIRING IS CARRIED OUT, IT WILL CAUSE AN ELECTRICAL FIRE OR
ELECTRICAL SHOCK.
• USE THE SPECIFIED CABLE (1.0 mm2 or more) AND CONNECT TIGHTLY FOR INDOOR/OUTDOOR
CONNECTION. CONNECT TIGHTLY AND CLAMP THE CABLE SO THAT EXTERNAL FORCE WILL NOT
BE ACTED ON THE TERMINAL.
• WIRE ROUTING MUST BE PROPERLY ARRANGED SO THAT CONTROL BOARD COVER IS FIXED
PROPERLY.
• DO NOT DAMAGE OR SCRATCH THE CONDUCTIVE CORE AND INNER INSULATOR OF THE CABLES.
• DO NOT DEFORM OR SMASH ON THE SURFACE OF THE CABLES. DO NOT PRESS OR FIX THE CORD
AND CABLES FIRMLY WITH STAPLES, etc.
• DO NOT USE THE INTER-CONNECTING CABLE. NEVER EXECUTE THE CONNECTION OF WIRING
WITH OTHER METHOD THAN THE APPROVED ONE. OTHERWISE, OVERHEAT, SMOKE OR FIRE MAY
BE GENERATED BY CONTACT ERROR.
• TURN OFF MAIN POWER SUPPLY AND BREAKER BEFORE ATTEMPTING ANY ELECTRICAL WORK.

1. Piping connections to the outdoor unit should be
arranged in the sequence A, B, C , D starting from the
bottom. (For each piping connection, the gas pipe is
on the bottom and the liquid pipe is on the top.)
2. When multiple indoor units are to be connected to
the outdoor unit, make the ends of the pipes and
wires from each indoor unit to ensure that they will
be connected to the outdoor unit correctly.
(Problems caused by indoor units being connected
to the outdoor unit incorrectly are very common in
multiple-unit installations.)
3. The length and height difference of the connecting
pipes between the indoor and outdoor units must be
within the ranges indicated below.
• Total piping length :
4 units (A + B + C + D) Multi,
Non. Additional refrigerant.................. 70 m

4. Connect 2 or more indoor units for heat pump.
5. If the outdoor unit is to be mounted on a wall, make
sure that the platform supporting it is sufficiently
strong. The platform should be designed and
manufactured to maintain its strength o ver a long
period of time, and sufficient consideration should be
given to ensuring that the outdoor unit will not fall.
6. When the outdoor unit is to be mounted high on a
wall, take particular care to ensure that parts do not
fall installer is protected.
7. When doing installation work on level ground, it is usual
to wiring and piping connections to the indoor units.
And/then make to the outdoor unit.
Howe v er if outdoor work is difficult it is possible instead
to make changes to the procedure.
For e xample by making adjustments to the wiring and
piping length on the inside (rather than the outside).
How to remove the side panel
1. Remove screws
of the side panel.
2. Pull the side panel
downward.
• Secure the outdoor unit with the fixing bolts and nuts

Tightening connection
Align the centers of the connecting pipes and tighten
the flare nut as far as possible with your fingers. Then
tighten the nut with a spanner and torque wrench as
shown in the figure.
CAUTION
• Do not apply excess torque. Otherwise, the nut
may crack depending on the conditions.
Evacuating
After the piping has been connected to all indoor
unit(s), you can perform the air purge together at once.
AIR PURGE
Evacuate the air in the connecting pipes and in the
indoor unit using vacuum pump.
Do not use the refrigerant in the outdoor unit.
For details, see the manual of vacuum pump.

Use a vacuum pump
Be sure to use a vacuum pump with counter-flow
prev ention function so that inside oil of the pump does
not flow backward into pipes of the air conditioner when
the pump stops. (If inside oil of the vacuum pump
enters into the air conditioner which adopts R410A, a
trouble of the refrigeration cycle may be caused.)
1. Connect the charge hose from the manifold valve to
the service port of the gas side packed valve.
2. Connect the charge hose to the port of vacuum pump.
3. Open fully the low pressure side handle of the gauge
manifold v alve.
4. Operate the vacuum pump to start for evacuating.
Perform evacuating for about 35 minutes if the piping
length is total 70 meters.
(25 minutes for total 50 meters)
(assuming a pump capacity of 27 liters per minute.)
Then confirm that the compound pressure gauge
reading is –101 kPa ( –76 cmHg).
5. Close the low pressure side valve handle of gauge
manifold.
6. Open fully the valve stem of the packed valves (both

Installation/Servicing T ools
In the case of an air conditioner using R410A, in order to prevent any other refrigerant from being charged accidentally, to
service por t 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 por t and packing for refrigerant cylinder” require 1/2 UNF 20 threads per inch corresponding to the
charge hose’s port size.

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 is changed.
In order to increase pressure resisting strength, hose materials and
port size are 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 with 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.
Exclusive for HFC refrigerant.

• Ce climatiseur utilise le nouveau réfrigérant HFC (R410A) qui ne nuit pas à la couche d’ozone.
Le réfrigérant R410A peut être contaminé par des impuretés telles que l’eau, les produits oxydants et les huiles
parce que la pression du réfrigérant R410A est 1.6 fois environ celle du réfrigérant R22. L’utilisation du nouveau
réfrigérant a été associée au changement de l’huile de la machine frigorifique. Par conséquent, lors de l’installation
prendre soin d’éviter toute pénétration de l’eau, des poussières, du réfrigérant précédent ou de l’huile de la machine
frigorifique dans le cycle de refroidissement du nouveau climatiseur.
Pour éviter tout mélange des réfrigérants ou des huiles de la machine frigorifique les dimensions des raccords de
l’orifice de remplissage de l’unité principale ou les outils de montage sont différents de ceux du climatiseur à
réfrigérant normal.
En conséquence des outils spéciaux sont requis (R410A) comme énoncé ci-après.
Pour le raccordement des tuyaux, utiliser des outils pour tuyaux neufs, propres et étanches à la pression,
spécialement conçus et fabriqués pour le R410A pour éviter toute pénétration de poussières ou d’eau. En outre, ne
pas utiliser les tuyaux existants car des problèmes concernant l’étanchéité à la pression et la présence d’impuretés
pourraient s’avérer .
ATTENTION
Cet appareil doit être branché sur le secteur à l’aide d’un commutateur avec une séparation de contact de 3 mm au
minimum.
