The incompatible lubricant easily separates from refrigerant
and is in the upper layer inside the suction muffler.
Raising position of the oil back hole enables to back the
lubricant of the upper layer to the compressor.
Since refrigerant and lubricant are compatible each, lubricant
backs to the compressor through the lower position oil back
hole.

INFORMATION FOR THE AIR CONDITIONER WITH R410A REFRIGERANT
• This room air conditioner adopts R410A of HFC refrigerant which never destroys the ozone layer.
Pay attention following points.
1 As R410A working pressure is 1.6 times higher than that of R22 of previous refrigerant, dedicated tools and piping are
required.
2 R410A is more affected by water and contaminations than R22. Keep R410A away from water and contaminations during
storage and while installing.
3 Use clean dedicated piping materials for R410A only which are strong enough against R410A pressure. Never use any
current pipes designed for R22.
4 Composition change may occur in R410A since it is a mixed refrigerant. When charging, charge liquid refrigerant to prevent
composition change.
NOTE : The unit of pressure has been changed to MPa on the international system of units(SI unit system).
The conversion factor is: 1(MPa [Gauge]) =10.2(kgf/ff[Gauge])

Gas leak detector
R410A pressures beyonds the measurement range of R22
gauges. Port diameters have been changed to prevent other kinds of
refrigerant from being charged into the units.
Hose material and cap size have been changed to improve the pressure
resistance.
Dedicated for HFC refrigerant.
1/4 and 3/8 wrenches can be used for both R22 and R410A units.
Description
Clamp bar hole has been enlarged to reinforce the spring strength in the tool.
Provided for flaring work (to be used with R22 flare tool).
Provided to prevent the back flow of oil. This adapter enables you to use
vacuum pumps.
It is difficult to measure R410A with a charging cylinder because the
refrigerant bubbles due to high pressure and high-speed vaporization

1.Tools dedicated for the air conditioner with R410A refrigerant
The following tools are required for R410A refrigerant. Some R22 tools can be substituted for R410A tools.
The diameter of the service port on the outdoor unit operation valve has been changed to prevent improper refrigerant
charging. Cap size has also been changed from 7/16 UNF with 20 threads to 1/2 UNF with 20 threads.
2.Refrigerant piping
1 Specifications
Use the refrigerant pipes that meet the following specifications.
• Use a copper pipe or a copper-alloy seamless pipe with a thickness of 0.7 mm or less, as the pressure resistance is in
sufficient.
2 Flaring work and flare nut
Flaring work for R410A pipes differs from that for the existing refrigerant pipes.
For details of flaring work, refer to Installation manual “6-1 FLARING WORK”.

3.Refrigerant oil
Apply the special refrigeration oil (accessories) to the flare and the union seat surfaces.
4.Air purge
Use the vacuum pump for air purging for the purpose of environmental protection.
5.Additional charge
For additional charging, charge the refrigerant from liquid phase of the gas cylinder. If the refrigerant is charged from the
gas phase, composition change may occur in the refrigerant inside the cylinder and the outdoor unit. However, charging the
liquid refrigerant all at once may cause the compressor to be locked. Thus, charge the refrigerant slowly.

PERFORMANCE CURVES8
MSZ-A09RV - MUZ-A12RV MSZ-A12RV - MUZ-A12RV -
The standard data contained in these specifications apply only to the operation of the air conditioner under normal conditions.
Since operating conditions vary according to the areas where these units are installed. The following information has been
provided to clarify the operating characteristics of the air conditioner under the conditions indicated by the performance curve.
(1) GUARANTEED VOLTAGE
198 ~ 264V, 50Hz
(2) AIR FLOW
Air flow should be set at MAX.
(3) MAIN READINGS
(1) Indoor intake air wet-bulb temperature ::WB
(2) Indoor discharge air wet-bulb temperature ::WB
(3) Outdoor intake air dry-bulb temperature ::DB
(4) Total input :W
(5) Indoor intake air dry-bulb temperature ::DB
(6) Outdoor intake air wet-bulb temperature ::WB
(7) Total input :W
Indoor air wet-bulb temperature difference on the left side of the chart on page 14 and 15 shows the difference between
the indoor intake air wet-bulb temperature and the indoor discharge air wet-bulb temperature for your reference at service.
How to measure the indoor air wet-bulb temperature difference
1. Attach at least 2 sets of wet-and dry-bulb thermometers to the indoor air intake as shown in the figure, and at least 2 sets
of wet-and dry-bulb thermometers to the indoor air outlet. The thermometers must be attached to the position where air
speed is high.
2. Attach at least 2 sets of dry-bulb thermometers to the outdoor air intake.
Cover the thermometers to prevent direct rays of the sun.
3. Check that the air filter is cleaned.
4. Open windows and doors of room.
5. Press the EMERGENCY OPERATION switch once (twice) to start the EMERGENCY COOL (HEAT) MODE.
6. When system stabilizes after more than 15 minutes, measure temperature and take an average temperature.
7. 10 minutes later, measure temperature again and check that the temperature does not change.

How to operate with fixed operational frequency of the compressor.
1. Press the EMERGENCY OPERATION switch on the front of the indoor unit , and select either the COOL mode or the
HEAT mode before starting to operate the air conditioner.
2. The compressor starts up.
The operational frequency of the compressor is 83Hz in the COOL mode and 58Hz in the HEAT mode.
3. The fan speed of the indoor unit is High.
4. This operation continues for 30minutes.
5. In order to release this operation, press the EMERGENCY OPERATION switch again, press any button on the remote
controller.
NOTE : The unit of pressure has been changed to MPa on the international system of units(SI unit system).
The conversion factor is: 1(MPa [Gauge]) =10.2(kgf/ff[Gauge])
