1 PRECAUTIONS FOR SAFETY
• Ensure that all Local, National and International regulations are satisfied.
• Read this“PRECAUTIONS FOR SAFETY” carefully before Installation.
• The precautions described below include the important items regarding safety. Observe them without fail.
• After the installation work, perform a trial operation to check for any problem.
Follow the Owner’s Manual to explain how to use and maintain the unit to the customer.
• Turn off the main power supply switch (or breaker) before the unit maintenance.
• Ask the customer to keep the Installation Manual together with the Owner’s Manual.
CAUTION
To Disconnect the Appliance from Main Power Supply
This appliance must be connected to the main power supply 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 conditioner.
WARNING
• Ask an authorized dealer or qualified installation professional to install/maintain the air condi-
tioner.
Inappropriate installation may result in water leakage, electric shock or fire.
• Turn off the main power supply switch or breaker before attempting any electrical work.
Make sure all power switches are off. Failure to do so may cause electric shock.
• Connect the connecting cable correctly.
If the connecting cable is connected in a wrong way, electric parts may be damaged.
• When moving the air conditioner for the installation into another place, be very careful not to
enter any gaseous matter other than the specified refrigerant into the refrigeration cycle.
If air or any other gas is mixed in the refrigerant, the gas pressure in the refrigeration cycle becomes abnor-
mally high and it may resultingly causes pipe burst and injuries on persons.
• Do not modify this unit by removing any of the safety guards or by by-passing any of the safety
interlock switches.
• Exposure of unit to water or other moisture before installation may cause short-circuit of
electrical parts.
Do not store it in a wet basement or expose to rain or water.
• After unpacking the unit, examine it carefully if there are possible damage.
• Do not install in a place that might increase the vibration of the unit.
• To avoid personal injury (with sharp edges), be careful when handling parts.
• Perform installation work properly according to the Installation Manual.
Inappropriate installation may result in water leakage, electric shock or fire.
New Refrigerant Air Conditioner Installation
• THIS AIR CONDITIONER ADOPTSTHE NEW HFC REFRIGERANT (R410A)WHICH DOES NOT DE-
STROY OZONE LAYER.
The characteristics of R410A refrigerant are ;easy to absorb water, oxidizing membrane or oil, and its pressure
is approx.1.6 times higher than that of refrigerant R22. Accompanied with the new refrigerant, refrigerating oil
has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or
refrigerating oil does not enter the refrigerating cycle.
To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging
port of the main unit and installation tools are charged from those for the conventional refrigerant.
Accordingly the exclusive tools are required for the new refrigerant (R410A).
For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust
does not enter. Moreover, do not use the existing piping because there are problems with pressure-resistance
force and impurity in it.
CAUTION

2
•When the air conditioner is installed in a small room, provide appropriate measures to ensure
that the concentration of refrigerant leakage occur in the room does not exceed the critical
level.
•Install the air conditioner securely in a location where the base can sustain the weight adequately.
•Perform the specified installation work to guard against an earthquake.
If the air conditioner is not installed appropriately, accidents may occur due to the falling unit.
•If refrigerant gas has leaked during the installation work, ventilate the room immediately.
If the leaked refrigerant gas comes in contact with fire, noxious gas may generate.
•After the installation work, confirm that refrigerant gas does not leak.
If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gas
might generate.
•Electrical work must be performed by a qualified electrician in accordance with the Installation
Manual. Make sure the air conditioner uses an exclusive power supply.
An insufficient power supply capacity or inappropriate installation may cause fire.
•Use the specified cables for wiring connect the terminals securely fix. To prevent external
forces applied to the terminals from affecting the terminals.
•Be sure to provide grounding.
Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone cables.
•Conform to the regulations of the local electric company when wiring the power supply.
Inappropriate grounding may cause electric shock.
•Do not install the air conditioner in a location subject to a risk of exposure to a combustible gas.

5 EVACUATING
Air Purge
This air conditioner can be installed up to the connecting pipe length and height difference in the following table.
With respect to the preservation of terrestrial environment, adopt “Vacuum pump”for air purge (Evacuate air in
the connecting pipes) when installing the unit.
•Do not discharge the refrigerant gas to the atmosphere to preserve the terrestrial environment.
•Use a vacuum pump to discharge the air (nitrogen, etc.) remained in the set.If the air remains, the capacity
may decrease.
For the vacuum pump, be sure to use one with backflow preventer so that the oil in the pump does not backflow
into the pipe of the air conditioner when the pump stops.(If oil in the vacuum pump is put in an air conditioner
including R410A, it may cause trouble on the refrigeration cycle.)
Vacuum pump
As shown in the figure, connect the charge hose after the manifold valve are closed completely.
Tighten valve and caps of the charge port surely.
Disconnect the charge hose from the charge port.
Open fully the valve stem or the valve handle. (First, at liquid side, then gas side)
Leave the vacuum pump as it is for 1 or 2 minutes, and check the indicator of the compound pressure gauge does not return.
Turn OFF the vacuum pump.
Close handle Low completely.
Execute vacuuming until the compound pressure gauge indicates –101kPa (–76cmHg). (*1)
Tighten the flare nut again.
Loosen the flare nut of the packed valve (Gas side) a little to check the air passes through. (*2)
Turn ON the vacuum pump (*1)
Open the handle Low fully.
Attach the connecting port of the charge hose with a projection to push the valve core (setting pin) to the charge port of the set.

7 FINAL INSTALLATION CHECKS
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 is approx.1.6 times higher than that of R22.
If installation work is incompletely finished, a gas leakage may
occur when pressure rises during operation.
Therefore, be sure to test the piping connections for leakage.
•Check gas leakage at the flare nut connections, valve stem cap
connections and service port cap fittings with a leak detector or
soap water. CAUTION
When the remote controller is used for the first time, it accepts an operation approx.5 minutes after the power
supply has been turned on.
It is not a trouble, but is because the setup of the remote controller is being checked.
For the second power-ON time and after, approx.1 minute is required to start the operation by the remote
controller.

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 check 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 sizes of opposite sides of flare nuts have been increased. Inciden-
tally, 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 the 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 the other for R410A.If the
vacuum pump oil (mineral) mixes with R410A, sludge may occur and
damage the equipment.
Exclusive for HFC refrigerant.
In the case of an air conditioner using R410A, in order to prevent any other refrigerant from being charged accidentally,
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
•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.

8 APPLICABLE CONTROL OF OUTDOOR UNIT
You can response to the following items by attaching the parts sold separately“Application
control kit”(TCB-PCOS1E).
Demand control
•It saves the capacity of the outdoor unit by outside Demand signal to correspond to the temporary peak cut.
•The capacity saving can be adjusted with three steps, 75%, 50%, and operation stop.
Night operation control (Sound reduction)
In order to reduce noise level in the night-time, if incorporating this control with a timer being on the market, the
outdoor operating sound level will be reduced by approx.5dB in cooling operation.
Compressor operation output
The check of the compressor operation time required of a maintenance etc.
Recovery method of refrigerant
•When recovering refrigerant in case of reinstallation
of the indoor or outdoor unit, etc., use the refrigerant
recovery switch on the terminal block of the outdoor
unit.
Work procedure
1. Turn on the power supply.
2. Using the remote controller, set FAN operation to
the indoor unit.
3. Pushing the refrigerant recovery switch on the
terminal block of the outdoor unit starts the forced
cooling operation.(Max. 10 minutes), and then the
refrigerant is recovered by operation of the valve.
4. After recovery of the refrigerant, push the refriger-
ant recovery switch together with closing the valve.
The operation stops.
5. Turn off the power supply.
DANGER
Take care for an electric shock because
the control P.C. board is electrified.
