PRECAUTIONS FOR SAFETY

For general public use

Power supply cord of parts of appliance for outdoor use shall be more than polychloroprene sheathed flexible 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

New Refrigerant Air Conditioner Installation

•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 exclusive tools are required for the new refrigerant (R410A) as shown below.

For connecting pipes, use new 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

To Disconnect the Appliance from the Mains Supply.

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

Engage Dealer or Specialist for Installation.

•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. MAKE SURE ALL POWER SWITCHES AND BREAKER TURN OFF. FAILURE TO DO SO MAY CAUSE ELECTRIC SHOCK.

•CONNECT THE CONNECTING CABLE CORRECTLY. IF THE CONNECTING CABLE IS CONNECTED BY WRONG WAY, ELECTRIC PARTS MAY BE DAMAGED.

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

•Secure the outdoor unit with the fixing bolts and nuts if the unit is likely to be exposed to a strong wind.

•Use Ø8 mm or Ø10 mm anchor bolts and nuts.

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 over 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.

However if outdoor work is difficult it is possible instead to make changes to the procedure.

For example 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.

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.

	(Unit : N·m)
Outer dia. of copper pipe	Tightening torque
Ø6.35 mm	14 to 18 (1.4 to 1.8 kgf•m)
Ø9.52 mm	33 to 42 (3.3 to 4.2 kgf•m)
Ø12.7 mm	50 to 62 (5.0 to 6.2 kgf•m)

• Tightening torque of flare pipe connections

Pressure of R410A becomes higher than that of R22. (Approx. 1.6 times) Therefore, using a torque wrench, tighten firmly the flare pipe connecting sections which connect the indoor and outdoor

units up to the specified tightening torque.

Incorrect connections may cause not only a gas leakage,

but also a trouble of the refrigeration cycle.

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 prevention 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 valve.

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 sides of Gas and Liquid).

7.Remove the charging hose from the service port.

8.Securely tighten the caps on the packed valves.

Check and Test Operation

For R410A, use the leak detector exclusively manufactured for HFC refrigerant (R410A, R134a, etc.).

*The conventional leak detector for HCFC refrigerant (R22, etc.) cannot be used because its sensitivity for HFC refrigerant lowers to approx. 1/40.

•Pressure of R410A becomes approx. 1.6 times of that of R22. If installation work is incompletely finished, a gas leakage may

occur in the cases such as pressure rise during operation. Therefore, be sure to test the piping connections for leaking.

• Check the flare nut connections, valve stem cap connections and service port cap connections for gas leak with a leak detector or soap water.

		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
	X		As pressure is high, it is impossible to measure by means of conven-
Gauge manifold			tional gauge. In order to prevent any other refrigerant from being
			charged, each port diameter is changed.
	X		In order to increase pressure resisting strength, hose materials and
Charge hose			port size are 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
for refrigerant charging			the indicated value by means of charging cylinder, as air bubbles occur.
Torque wrench	X		The size of opposite sides of flare nuts have been increased. Inciden-
(nominal diam. 1/2, 5/8)			tally, a common wrench is used for nominal diameters 1/4 and 3/8.
Flare tool			By increasing the clamp bar’s receiving hole, strength of spring in the
(clutch type)			tool has been improved.
Gauge for projection adjustment	____	____	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
Vacuum pump adapter			hose. The charge hose connecting part has two ports-one for conven-
			tional 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	X		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 corresponding to the charge hose’s port size.

ATTENTION Nouvelle Installation de climatisation à réfrigérant

• 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

Débranchement de l’appareil du secteur d’alimentation.

Cet appareil doit être branché sur le secteur à l’aide d’un commutateur avec une séparation de contact de 3 mm au minimum.

Pour ce climatiseur le fusible (25A type D ) doit être employé dans la line d’alimentation.
