1PRECAUTIONS FOR SAFETY
• Ensure that installation work satisfy all Local, National
International regulations.
• 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 test 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.
WARNING
• Ask an authorized dealer or qualied installation
professional to install / maintain the air conditioner.
Inappropriate installation may result in water leakage, electric
shock or re.
• 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 wire correctly.
If the connecting wire 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 specied refrigerant into the
refrigeration cycle.
If air or any other gas is mixed in the refrigerant, the gas
pressure in the refrigeration cycle becomes abnormally high and
it as a result 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 re.
• 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 specied 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 re, noxious
gas may generate.
• After the installation work, conrm that refrigerant gas does
not leak.
If refrigerant gas leaks into the room and ows near a re source,
such as a cooking range, noxious gas might generate.

5-EN 6-EN
– 3 –
• Electrical work must be performed by a qualied electrician
in accordance with the Installation Manual. Make sure the air
conditioner uses an exclusive power supply.
An insufcient power supply capacity or inappropriate installation
may cause re.
• Use the specied wires to connect them to the terminals.
Securely x them so that the external tension to the wires
do not affect the connecting part of the terminals.
• Conform to the regulations of the local electricity 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.
If a combustible gas leaks, and stays around the unit, a re may
occur.
CAUTION
• This Air Conditioner has adopted a refrigerant HFC (R32 or
R410A) which does not destroy the ozone layer.
- As the R32 or R410A refrigerant is easily affected by impurities
such as moisture, oxidized lm, oil, etc., due to the high
pressure, be careful not to allow the moisture, dirt, existing
refrigerant, refrigerating machine oil, etc., to get mixed up in the
refrigeration cycle during the installation work.
- A special tool for the R32 or R410A refrigerant is required for
installation.
- Use a new and clean piping materials for the connecting pipe
so that moisture and dirt are not mixed together during the
installation work.
• Tighten are nuts using a torque wrench according to the
specied method.
If the are nuts are tightened too much, they may later break and
cause refrigerant leak.
• Wear protective gloves during installation.
Failure to wear the gloves causes an injury on your hands
through contact with parts.

• Under no circumstances shall potential sources of ignition be
used in the searching for or detection of refrigerant leaks.
• A halide torch (or any other detector using a naked ame)
shall not be used.
• Electronic leak detectors may be used to detect refrigerant
leaks but, in the case of ammable refrigerants, the sensitivity
may not be adequate, or may need re-calibration. (Detection
equipment shall be calibrated in a refrigerant-free area.)
• Ensure that the detector is not a potential source of ignition
and is suitable for the refrigerant used.
• Leak detection equipment shall be set at a percentage of the
LFL of the refrigerant and shall be calibrated to the refrigerant
employed, and the appropriate percentage of gas
(25% maximum) is conrmed.
• Leak detection uids are also suitable for use with most
refrigerants but the use of detergents containing chlorine shall
be avoided as the chlorine may react with the refrigerant and
corrode containing chlorine.
• If a leak is suspected, all naked ames shall be removed/
extinguished.
• If a leakage of refrigerant is found which requires brazing,
all of the refrigerant shall be recovered from the system, or
isolated (by means of shut off valves) in a part of the system
remote from the leak.
14. Leak detection methods
• Electronic leak detectors shall be used to detect ammable
refrigerants leak, but the sensitivity may not be adequate,
or may need re-calibration. (Detection equipment shall be
calibrated in a refrigerant-free area.)
• Ensure that the detector is not a potential source of ignition
and is suitable for the refrigerant used.
• Leak detection equipment shall be set at a percentage of the
LFL of the refrigerant and shall be calibrated to the refrigerant
employed and the appropriate percentage of gas
(25% maximum) is conrmed.
• Leak detection uids are suitable for use with most
refrigerants but the use of detergents containing chlorine shall
be avoided as the chlorine may react with the refrigerant and
corrode the copper pipe-work.
• If a leak is suspected, all naked ames shall be removed/
extinguished.
• If a leakage of refrigerant is found which requires brazing,
all of the refrigerant shall be recovered from the system, or
isolated (by means of shut off valves) in a part of the system
remote from the leak.
• Oxygen free nitrogen (OFN) shall then be purged through the
system both before and during the brazing process.
15. Removal and evacuation
• When breaking into the refrigerant circuit to make repairs or
for any other purpose, Conventional procedures shall be used.
However, it is important that best practice is followed since
ammability is a consideration.The following procedure shall
be adhered to:
- remove refrigerant;
- purge the circuit with inert gas;
- evacuate;
- purge again with inert gas;
- open the circuit by cutting or brazing;
• The refrigerant charge shall be recovered into the correct
recovery cylinders.
• The system shall be “Flushed” with OFN to render the unit
safe.

Caution when installing the PMV Kit at a place with low background noise
This PMV Kit has a built-in pulse motor valve (expansion valve), generating refrigerant sounds during operation.
Thus, avoid installing it in the following rooms with low background noise and install it in isolated spaces from a
living space.
• Room with low background noise: bedrooms, hospital rooms, or hotel rooms.
• Room without ceiling boards where the PMV Kit is not isolated from living space.
• Room with opening part on the ceiling.
2INSTALLATION OF R32 OR R410A
REFRIGERANT AIR CONDITIONER
This PMV Kit adopts the HFC refrigerant (R32 OR R410A) which does not deplete the ozone layer.
Be sure to read and follow the Installation Manuals for indoor and outdoor units for precautions regarding the
characteristics of the refrigerant, the tools used, and the refrigerant piping. It is different from the conventional
refrigerant (R22).
Refrigerant piping
• Piping material used for the conventional refrigerant cannot be used.
• Use copper pipe with 0.8 mm or more thickness for Dia.6.4, Dia.9.5, Dia.12.7 mm.
• Flare nut and are works are also different from those of the conventional refrigerant.
Take out the are nut attached to the unit of the air conditioner, and use it.

23-EN 24-EN
– 12 –
PMV Kit outline
Purpose of using
In the case of very quiet room, and also very nervous for indoor unit noise level, PMV Kit should be installed
before indoor unit which should become lower noise level.
Multi-indoor units have Pulse Motor Valve (PMV) for control refrigerant ow.
Multi-air conditioner, in unstable condition, for example starting time, owing noise of refrigerant or defrosting time
can be heard conspicuously.
This refrigerant noise mainly comes from PMV. Especially in very quiet room, for example bed room, somebody
feels uncomfortable for this refrigerant noise from PMV.
Main purpose of PMV Kit restrains refrigerant noise which comes from PMV installed in indoor unit.
PMV Kit should be installed at out of residence area, for example back of ceiling board or along passage way.
After installed PMV Kit, control function of refrigerant shifts to PMV of PMV Kit and PMV in indoor unit is not used.
After that, refrigerant noise of PMV will be coming from back ceiling board, and refrigerant noise of indoor unit may
be restrained.

REQUIREMENT
Use a leak detector manufactured exclusively for HFC refrigerant (R32 or R410A, R134a, etc.).
Heat insulating process
Perform heat insulating for pipes at liquid side and
gas side separately.
In cooling time, temperature at both liquid and gas
sides becomes lower.
Therefore, perform heat insulating process
sufciently to avoid dewing.
• For heat insulator of pipe at gas side, be sure to
use one with heat-resisting temp. 120°C or more.
• Using the attached heat insulating pipe, perform
