INFORMATION FOR THE AIR CONDITIONER WITH R410A REFRIGERANT

New Specification Current Specification

The incompatible refrigerating oil 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
refrigerating oil of the upper layer to flow back to the
compressor.

Since refrigerant and refrigerating oil are compatible each,
refrigerating oil backs to the compressor through the lower
position oil back hole.

• This room air conditioner adopts an HFC refrigerant (R410A) which never destroys the ozone layer.

• Pay particular attention to the following points, though the basic installation procedure is same as that for R22 conditioners.
1 As R410A has working pressure approximate 1.6 times as high as that of R22, some special tools and piping parts/

materials are required. Refer to the table below.

2 Take sufficient care not to allow water and other contaminations to enter the R410A refrigerant during storage and

installation, since it is more susceptible to contaminations than R22.

3 For refrigerant piping, use clean, pressure-proof parts/materials specifically designed for R410A. (Refer to 2. Refrigerant

piping.)

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 has high pressures beyond the measurement range of existing
gauges. Port diameters have been changed to prevent any other refrigerant
from being charged into the unit.

Hose material and cap size have been changed to improve the pressure
resistance.

Dedicated for HFC refrigerant.

6.35 mm and 9.52 mm

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 stop valve in outdoor unit has been changed to prevent any other refrigerant being
charged into the unit. Cap size has 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 0.8 mm. Never use any pipe with a thickness less
than 0.8mm, as the pressure resistance is insufficient.

2 Flaring work and flare nut

Flaring work for R410A pipe differs from that for R22 pipe.
For details of flaring work, refer to Installation manual “FLARING WORK”.

3.Refrigerant oil

Apply the special refrigeration oil (accessories: packed with indoor unit) to the flare and the union seat surfaces.

4.Air purge

• Do not discharge the refrigerant into the atmosphere.
Take care not to discharge refrigerant into the atmosphere during installation, reinstallation, or repairs to the refrigerant

circuit.

• 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. In this case, ability of the refrigerating cycle decreases or normal operation can be impossible. However,
charging the liquid refrigerant all at once may cause the compressor to be locked. Thus, charge the refrigerant slowly.

How to measure the indoor air wet-bulb/dry-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 wet-and 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

<MUH-A07/A09/A12WV>) 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.

(5) TEMPERATURES buttons

In “I FEEL CONTROL” ( ) mode, set temperature is decided by the microprocessor based on the room temperature.
In addition, set temperature can be controlled by TOO WARM or TOO COOL buttons when you feel too cool or too
warm. Each time the TOO WARM or TOO COOLbutton is pressed, the indoor unit receives the signal and emits a beep
tone.

● Fuzzy control

When the TOO COOL or TOO WARM button is pressed, the microprocessor changes the set temperature, considering
the room temperature, the frequency of pressing TOO COOL or TOO WARM button and the user’s preference to heat or
cool. So this is called “Fuzzy control”, and works only in “I FEEL CONTROL” mode.
In DRY mode of “I FEEL CONTROL”, the set temperature doesn’t change.

11-6. FAN MOTOR CONTROL

(1) Rotational frequency feedback control

The indoor fan motor is equipped with a rotational frequency sensor, and outputs signal to the microprocessor to
feedback the rotational frequency. Comparing the current rotational frequency with the target rotational
frequency (High,Med.,Low), the microprocessor controls SR141 and adjusts fan motor electric current to make the
current rotational frequency close to the target rotational frequency. With this control, when the fan speed is switched,
the rotational frequency changes smoothly.

High High

Med.

Low

(2) Fan motor lock-up protection

When the rotational frequency feedback signal is not output for 12 seconds, (or when the microprocessor cannot detect
the signal for 12 seconds) the fan motor is regarded locked-up. Then the electric current to the fan motor is shut off. 3 min­utes later, the electric current is applied to the fan motor again. During the fan motor lock-up, the OPERATION INDICA­TOR lamp flashes on and off to show the fan motor abnormality. (Refer to page 109.)

11-7. AUTO VANE OPERATION

(1) Vane motor drive

These models are equipped with a stepping motor for the horizontal vane. The rotating direction, speed, and angle of
the motor are controlled by pulse signals (approx. 12V) transmitted from indoor microprocessor.

(2) The horizontal vane angle and mode changes as follows by pressing the VANE CONTROL button.

(3) Positioning

The vane is once pressed to the vane stopper below to confirm the standard position and then set to the desired angle.
Confirming of standard position is performed in case of follows.
(a) When the OPERATE/STOP(ON/OFF) button is pressed.
(b) When the vane control is changed from AUTO to MANUAL.
(c) When the SWING is finished.
(d) When the test run starts.
(e) When the power supply turns ON.

(4) VANE AUTO ( ) mode

In VANE AUTO mode, the microprocessor automatically determines the vane angle to make the optimum room-temper­ature distribution.

1 In COOL and DRY operation

Vane angle is fixed to Angle 1.

2 In FAN operation <MU-A07/A09/A12WV>

2 In HEAT operation

(5) Dew prevention

During COOL or DRY operation at Vane Angle 4 or 5 when the cumulative operation time of compressor exceeds 1
hour, the vane angle automatically changes to Angle 1 for dew prevention.

(6) SWING MODE ( )

By selecting SWING mode with the VANE CONTROLbutton, the horizontal vane swings vertically. The remote controller
displays “ ”.

NOTE : If the temperature of RT12 reads from 24°C to 28°C at the air conditioner stating , this control works.

(8) ECONO COOL ( ) operation (ECONOmical operation)

When the ECONO COOL button is pressed in COOL mode, set temperature is automatically set 2°C higher than that in
COOL mode.
Also the horizontal vane swings in various cycle according to the temperature of indoor heat exchanger(RT12).
SWING operation makes you feel cooler than set temperature. So, even though the set temperature is higher than that
in COOL mode, the air conditioner can keep comfort. As a result, energy can be saved.
ECONO COOL operation is cancelled when the ECONO COOL button is pressed once again or VANE CONTROL but­ton is pressed or operation mode is changed.

NOTE : ECONO COOL operation does not work in COOL mode of “I FEEL CONTROL”.

SWING operation

In swing operation of ECONO COOL operation mode, the initial air flow direction is adjusted to “Horizontal”.
According to the temperature of indoor coil thermistor RT12 at starting of this operation, next downward blow time is
decided. Then when the downward blow has been finished, next upward blow time is decided.
For initial 10 min. the swing operation is performed in table G~H for quick cooling.
Also, after 10 min. when the difference of set temperature and room temperature is more than 2 degrees, the swing
operation is performed in table D~H for more cooling.
The air conditioner repeats the swing operation in various cycle as follows.

11-11-2. Outline of main power supply circuit

1. At the start of operation
Rush current is generated the instant the electricity is turned on to the main power
supply circuit to operate the compressor.
To prevent the rush current from running into the main power supply circuit, R64A, R64B (Current-limiting resistor) absorbs
the rush current.
After the rush current is absorbed, X64 (Relay) is ON and the circuit to R is
short-circuited, then the electricity to R is bypassed.
When X64 is ON, the system starts the operation of compressor.

2. At normal operation

The noise of alternating current of power supply is eliminated by L61, L62 (Common mode choke coil).
Then DS61, DS62 (Diode stack) performs full-wave rectification of alternating current and the
alternating current is converted to direct current.

C61, C62 and C63 (Smoothing capacitor) stabilizes the power supply converted to direct current from alternating current
and supplies it to IPM (Intelligent power module).
Direct current rectified by DS61, DS62 is converted to three-phase alternating current by IPM.
Microcomputer installed in the electronic control P.C. board controls frequency and voltage of three-phase alternating
current converted by IPM.
Three-phase alternating current is supplied from IPM to the compressor with frequency and voltage decided by
microcomputer based on various kinds of information.
CT61, CT761 (Current transformer) measures the current of main power supply circuit.

3. Power-factor improvement of power supply and harmonics control

Although C61, C62, and C63 [smoothing capacitor] are used in this inverter circuit in order to supply direct-current stably,

since the charge current to a capacitor turns into intermittent current in the stable circuit with only a capacitor, power factor
of power supply gets worse and harmonics ingredient also becomes large.

Then, AFM [active filter module] and L [reactor] have been arranged on direct-current circuit, and the improvement of

power factor and generating of harmonics are controlled by bringing the intermittent current waveform of alternating
power supply close to sine wave synchronized with the power supply voltage waveform. (Note 1)

Note 1: When short-circuited between plus and minus pole of direct-current circuit,

alternating power supply current flows. By controlling time of short-circuiting to flow proper amount of current in the
intermittent portion of alternating power supply current constantly, the current waveform of alternating power supply is
brought close to sine wave.

4. Removal of electric noise

Because of the noise filter circuit formed by L61 and L62 [CMC coil] and the capacitor on the noise filter board, the electric

noise of the alternating power supply supplied to the main power supply circuit is removed.

Moreover, common mode noise is absorbed with the above-mentioned noise filter, and the normal mode noise is

absorbed in the noise filter circuit formed by L63 [NMC coil] and the capacitors [C650A, C650B, and C650C] on the
control board so that the electric noise generated in the inverter circuit may not leak out.

Six power transistors that outputs the direct current waveform as three-phase alternating current waveform, the driving
circuit which operates the power transistors, and the overcurrent detecting circuit which protects the power transistors are
built into the IPM. It can simplify and miniaturize the control circuit.

6.AFM [Active Filter Module]
The circuit that detects power supply voltage waveform, the circuit that detects the current flowing in module, the switching

element that short-circuits between plus and minus pole of direct-current circuit, and the switching element driving current
are built into AFM.
The current waveform is automatically adjusted by controlling the interval of short-circuit between plus and minus pole of
direct-current circuit so that the waveform of actual current flowing to service power supply is synchronized with the phase
of power supply voltage waveform detected by AFM.

11-12. Optimal voltage control

The purpose of optimal voltage control is to operate the compressor at optimal
voltage that meets the load detected by the power factor of the compressor.

1. Optimal

As shown on the right the efficiency (ratio of output against input) of the
motor in the compressor becomes optimal when the sliding (ratio of differ­ence between the actual number of rotation and the number of synchronous
rotation of motor) is one fixed value. The value of sliding can be calculated
from the power factor since the sliding and the power factor are mutually
related as shown in the table on the right. To make the value of sliding so
that the efficiency of motor is optimal, the power factor of the compressor is
detected. Then the detected power factor is controlled so that its efficiency
can be high. As a result, it is possible to operate the compressor at optimal
voltage.

2. How to determine the optimal voltage

Compare the detected power factor with the target power factor so that the efficiency of motor is optimal, the voltage
correction value is changed and the optimal output voltage is determined.
Optimal output voltage[V]= Standard voltage at certain frequency [V]x voltage correction value(%)

Determination of LEV standard opening in each indoor unit

• The standard opening is on the straight line, which connects an each standard point in the section where divided
into seven according to the operation frequency of compressor as shown in the figure below.
(LEV opening is controlled in proportion to the operation frequency.)

Note: Opening is adjusted at the standard opening according to the indoor unit conditions.

However, inclination of standard opening in each point of opening does not change with the original curve.

• Add opening provided in Difference in Capacity in the table below to the standard opening from 1 to 8,
when capacity of the indoor unit is excluding code 1.

• Add opening provided in Difference in Operation number in the table below to determined LEV opening for
each indoor unit, when 2, 3 or 4 indoor units are operated at the same time.

Note: Even when the adjusted standard opening exceeds the driving range from 59 to 500 pulse, actual

driving output opening is in a range from 59 to 500 pulse.
