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 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 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 a 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.

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.

nected to 4 directions.
Take off the knockout part of the pipe cover in which
pipes or wires pass through the base plate.
•As shown in the figure, do not remove the pipe cover
from the cabinet so that the knockout hole can be
easily punched.To knock out, it is easily taken off by
hands by punching a position at the lower side of 3
connected parts with screwdriver along the guide
line.
•After marking the knockout hole, remove the burr and
mount the attached protective bush and guard
material for pass-through part in order to protect
pipes and wires.
After connecting the pipes, be sure to mount the pipe
cover.The pipe cover is easily mounted by cutting off
the slit at the lower part of the pipe cover.
How to remove the front panel
1. Remove screws of the front panel.
2. Pull the front panel downward.
Removing the front panel, the electric parts appear at
the front side.
•The metal pipes are attachable to the piping holes.
If the size of the used power pipe does not match
with the hole, adjust the hole size to match with pipe
size.
•Be sure to fix the power cable and indoor/outdoor
connecting cable with bundling band sold on the
market so that they do not make contact with the
compressor and discharge pipe.
(Temperature of the compressor and discharge pipe
becomes high.)
In order to avoid the force applied to on the connect-
ing section, be sure to fix the cables to the cord
clamps provided on the pipe valve fixing plate and the

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.

How to open the valve
Handle position
*1. Use the vacuum pump, vacuum pump adapters,
and gauge manifold referring to the manuals
attached to each tool before using them.For the
vacuum pump, check oil is filled up to the specified
line of the oil gauge.
*2. While the air is purged, check again that the
connecting port of charge hose, which has a
projection to push the valve core, is firmly con-
nected to the charge port.
Valve handling precautions
•Open the valve stem or the handle until it strikes
the stopper. It is unnecessary to apply further
force.

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 munute is required to start the operation by the remote controller.
Useful Functions Self-Diagnosis by LED Indication
In addition to the code checking by remote controller of the indoor unit, troubles of the outdoor unit can be diag-
nosed by LED indications on the cycle control P.C. board of the outdoor unit. Utilize them for various checks.
For the check by remote controller of the indoor unit, refer to the Installation Manual of the indoor unit.
Before a check, confirm each bit of the DIP switch SW800 is set to OFF position.

Installation/ServicingTools 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 acciden-
tally, 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.

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 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 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 one for R410A.
If the vacuum pump oil (mineral) mixes with R410A a sludge may occur
and damage the equipment.
Exclusive for HFC refrigerant.
