6.2 Servicing
(1) Evacuation
The evacuation is an procedure to purge impurities ...... noncondensable gas, air, moisture from the refrigerant equipment by using
a vacuum pump. Since the refrigerant R22 is very insoluble in water, even a small amount of moisture left in the refrigerant
equipment will freeze, causing what is called water clogging.
¡ Evacuation procedure
(a)
Check to ensure that there is no internal pressure in the unit. If there is an internal pressure, it
should be relieved through the check joint.
(b)
Connect the service hoses of the gauge manifold to the check joint of the gas & liquid piping.
(c)
Connect a vacuum pump to the charge hose A . Repeat evacuation in the following sequence.
Liquid side
Start the vacuum pump
Gas side
Operate the vacuum pump for more than 15 minutes after –0.1MPa
(–76 cmHg) is indicated.
Check joint
Close low pressure valve 1 of gauge manifold.
Service hose
Gauge
manifold
Stop the vacuum pump.
Charge hose
Notes (1) Do not use the refrigerant pressure to expel air.
(2) Do not use the compressor for evacuation.
(3) Do not operate the compressor in the vacuum condition.

Refrigerant
cylinder
(2) Refrigerant charge
(a)
Discharge refrigerant entirely from the unit and evacuate the unit.
(b)
Keep the gauge manifold and connect a refrigerant cylinder to the unit.
Note: Addition of refrigerant without evacuation is unreasonable, because it will result in low charge or overcharge.
(c)
Record the weight of the refrigerant cylinder on the balance. This is necessary for making sure of the charged refrigerant
amount.
(d)
Purge air from the charge hose A .
Firstly loose the connecting portion of the charge hose A at the gauge manihold side and open the valve 3 for a few seconds,
and then immediately retighten it after observing that gas is blow out from the loosened portion.
(e)
Open the valve 1 and 3 after discharging air from the charge hose A , then the gas refrigerant begins flowing from the
cylinder into the unit. Be sure to erect the refrigerant cylinder upright to let gas refrigerant flow into the unit.
(f)
When refrigerant has been charged into the system to some extent, refrigerant flow becomes stagnant, when that happens,
start the compressor in cooling cycle until the unit is filled with gas to the specified weight.
(g)
Making sure of the refrigerant amount, close the valve 3.
(h)
Disconnect the charge hose from the unit. Cover the valve ports of the refrigerant piping with caps and tighten them securely.
(i)
Check for gas leakage applying a gas leak detector along the piping line.
(j)
Start the air conditioner and make sure of its operating condition ...... high side and low side pressures and temperature
difference between suction air and outlet air.

This prevents dew condensation, in the indoor unit, from occurring.
(a)
Operating condition: when 52C is kept ON for 30 min. after the unit starts operation.
(b)
Operation content: forces the indoor fan to change from Speed 1 to Speed 2.
(c)
Resetting condition: When 52C is off, or when dew condensation prevention control has been operating continuously for
30 minutes.
(12) Frost prevention for indoor heat exchanger [Preventing frost accumulation on the indoor heat exchanger]
During the Cooling or Dry operation in low room air temp. condition, evaporating temperature will decrease and consequently
indoor heat exchanger sometimes gets clogged with frost (or ice).
In order to prevent this trouble, compressor is stopped by under mentioned condition by indoor heat exchanger sensor (Th2) and
timer (built into micro computer circuit) functions.
Also indoor fan is changed over to speed 1.

operation mode. (After 3 minutes has passed the thermal operation is effective.)
However, stopping the compressor via a stop signal or protection control has priority.
(14) Self diagnosis function
When something abnormal happens on the outdoor unit, indoor unit fan motor and each thermistor (heat exchanger, room temperature, ) it will be indicated by flashing lamps.
(a)
Abnormality of outdoor unit: When the indoor heat exchanger temperature does not fall to 25ºC or below for 40 minutes
(12 type : 20 minutes) after 5 minutes have elapsed since the compressor operation start,
the abnormality stop occurs. (The timer lamp flashes 5 times.)
(b) Abnormality of indoor fan motor: The indoor fan motor revolves at a rate under 300 rpm for 30 seconds or longer, the
RUN lamp will flash.
(c)
Abnormality of heat exchanger thermistor: RUN lamp will flashing when the input temperature of the heat exchanger
thermistor measures less than –20ºC for more than 3 seconds with the
airconditioner “OFF”. (will not flashing during operation)
(d) Abnormality room temperature thermistor: RUN lamp will flashing when the input temperature of the room temperature thermistor measures less than –20ºC for more than 3 seconds
with the airconditioner “OFF”. (will not flashing during operation)

points which are related to the strong possibility of an installation done in error resulting in death or serious injury are listed in the
WARNING section. However, there is also a possibility of serious consequences in relationship to the points listed in the
CAUTION section as well. In either case, important safety related information is indicated, so by all means, properly observe
all that is mentioned.
¡ After completing the installation, along with confirming that no abnormalities were seen from the operation tests, please explain
operating methods as well as maintenance methods to the user (customer) of this equipment, based on the owner’s manual.
Moreover, ask the customer to keep this sheet together with the owner’s manual.
WARNING
¡ This system should be applied to places as households, residences and the like. Application to inferior environment such as
engineering shop could cause equipment malfunction.
¡ Please entrust installation to either the company which sold you the equipment or to a professional contractor. Defects from improper
installations can be the cause of water leakage, electric shocks and fires.
¡ Execute the installation accurately, based on following the installation manual. Again, improper installations can result in water
leakage, electric shocks and fires.
¡ For installation, confirm that the installation site can sufficiently support heavy weight. When strength is insufficient, injury can result
from a falling of the unit.
¡ For electrical work, please see that a licensed electrician executes the work while following the safety standards related to electrical
equipment, and local regulations as well as the installation instructions, and that only exclusive use circuits are used.
Insufficient power source circuit capacity and defective installment execution can be the cause of electric shocks and fires.
¡ Accurately connect wiring using the proper cable, and insure that the external force of the cable is not conducted to the terminal
connection part, through properly securing it improper connection or securing can result in heat generation or fire.
¡ Take care that wiring does not rise upward, and accurately install the lid/service panel.It’s improper installation can also result heat
generation or fire.
¡ When setting up or moving the location of the air conditioner, do not mix air etc. or anything other than the designated refrigerant
(R22) within the refrigeration cycle.
Rupture and injury caused by abnormal high pressure can result from such mixing.
¡ Always use accessory parts and authorized parts for installation construction. Using parts not authorized by this company can result
in water leakage, electric shock, fire and refrigerant leakage.
¡ Ventilate the work area when refrigerant leaks during the operation.
Coming in contact with fire, refrigerant could generate toxic gas.
¡ Confirm after the foundation construction work that refrigerant does not leak.
If coming in contact with fire of a fan heater, a stove or movable cooking stove, etc., refrigerant leaking in the room could generate
toxic gas.
CAUTION
¡ Execute proper grounding. Do not connect the ground wire to a gas pipe, water pipe, lightning rod or a telephone ground wire.
Improper placement of ground wires can result in electric shock.
¡ The installation of an earth leakage breaker is necessary depending on the established location of the unit.
No installing an earth leakage breaker may result in electric shock.
¡ Do not install the unit where there is a concern about leakage of combustible gas.
The rare even of leaked gas collecting around the unit could result in an outbreak of fire.
¡ For the drain pipe, follow the installation manual to insure that it allows proper drainage and thermally insulate it to prevent
condensation. Inadequate plumbing can result in water leakage and water damage to interior items.
¡ Install the outdoor unit so that the aluminum fins on the air heat exchanger cannot be touched. Failure to observe this may result in
injury.
Cautions for installation
1 The system should be applied to places as households, residences and the like.
2 The equipment shall be installed in accordance with national wiring regulations.
3 The connection to the fixed wiring of the mains supply must be made via a double pole isolating switch with a contact gap of at
least 3mm in each pole.

6.2 Servicing
(1) Evacuation
The evacuation is an procedure to purge impurities ...... noncondensable gas, air, moisture from the refrigerant equipment by using
a vacuum pump. Since the refrigerant R22 is very insoluble in water, even a small amount of moisture left in the refrigerant
equipment will freeze, causing what is called water clogging.
¡ Evacuation procedure
(a)
Check to ensure that there is no internal pressure in the unit. If there is an internal pressure, it
should be relieved through the check joint.
(b)
Connect the service hoses of the gauge manifold to the check joint of the gas & liquid piping.
(c)
Connect a vacuum pump to the charge hose A . Repeat evacuation in the following sequence.
Liquid side
Start the vacuum pump
Gas side
Operate the vacuum pump for more than 15 minutes after –0.1MPa
(–76 cmHg) is indicated.
Check joint
Close low pressure valve 1 of gauge manifold.
Service hose
Gauge
manifold
Stop the vacuum pump.
Charge hose
Notes (1) Do not use the refrigerant pressure to expel air.
(2) Do not use the compressor for evacuation.
(3) Do not operate the compressor in the vacuum condition.

Refrigerant
cylinder
(2) Refrigerant charge
(a)
Discharge refrigerant entirely from the unit and evacuate the unit.
(b)
Keep the gauge manifold and connect a refrigerant cylinder to the unit.
Note: Addition of refrigerant without evacuation is unreasonable, because it will result in low charge or overcharge.
(c)
Record the weight of the refrigerant cylinder on the balance. This is necessary for making sure of the charged refrigerant
amount.
(d)
Purge air from the charge hose A .
Firstly loose the connecting portion of the charge hose A at the gauge manihold side and open the valve 3 for a few seconds,
and then immediately retighten it after observing that gas is blow out from the loosened portion.
(e)
Open the valve 1 and 3 after discharging air from the charge hose A , then the gas refrigerant begins flowing from the
cylinder into the unit. Be sure to erect the refrigerant cylinder upright to let gas refrigerant flow into the unit.
(f)
When refrigerant has been charged into the system to some extent, refrigerant flow becomes stagnant, when that happens,
start the compressor in cooling cycle until the unit is filled with gas to the specified weight.
(g)
Making sure of the refrigerant amount, close the valve 3.
(h)
Disconnect the charge hose from the unit. Cover the valve ports of the refrigerant piping with caps and tighten them securely.
(i)
Check for gas leakage applying a gas leak detector along the piping line.
(j)
Start the air conditioner and make sure of its operating condition ...... high side and low side pressures and temperature
difference between suction air and outlet air.
6.3 Power supply remote operation
When the remote part on indoor unit PCB is modified, the air conditioner is turned ON-OFF by power supply ON-OFF operation
without using remote control switch.
After the power supply remote operation, the operation contents can be modified by the remote controller.

¡ Though the precautionary points indicated herein are divided under two headings,
WARNING and
CAUTION , those points
which are related to the strong possibility of an installation done in error resulting in death or serious injury are listed in the
WARNING section. However, there is also a possibility of serious consequences in relationship to the points listed in the
CAUTION section as well. In either case, important safety related information is indicated, so by all means, properly observe all
that is mentioned.
¡ After completing the installation, along with confirming that no abnormalities were seen from the operation tests, please explain
operating methods as well as maintenance methods to the user (customer) of this equipment, based on the owner’s manual.
Moreover, ask the customer to keep this sheet together with the owner’s manual.
WARNING
¡ This system should be applied to places as households, residences and the like. Application to inferior environment such as engineering shop could cause equipment malfunction.
¡ Please entrust installation to either the company which sold you the equipment or to a professional contractor.
Defects from improper installations can be the cause of water leakage, electric shocks and fires.
¡ Execute the installation accurately, based on following the installation manual. Again, improper installations can
result in water leakage, electric shocks and fires.
¡ For installation, confirm that the installation site can sufficiently support heavy weight. When strength is insufficient, injury can result from a falling of the unit.
¡ For electrical work, please see that a licensed electrician executes the work while following the safety standards
related to electrical equipment, and local regulations as well as the installation instructions, and that only exclusive use circuits are used.
Insufficient power source circuit capacity and defective installment execution can be the cause of electric shocks
and fires.
¡ Accurately connect wiring using the proper cable, and insure that the external force of the cable is not conducted
to the terminal connection part, through properly securing it improper connection or securing can result in heat
generation or fire.
¡ Take care that wiring does not rise upward, and accurately install the lid/service panel. It’s improper installation
can also result in heat generation or fire.
¡ When setting up or moving the location of the air conditioner, do not mix air etc. or anything other than the
designated refrigerant (R22) within the refrigeration cycle.
Rupture and injury caused by abnormal high pressure can result from such mixing.
¡ Always use accessory parts and authorized parts for installation construction. Using parts not authorized by this
company can result in water leakage, electric shock, fire and refrigerant leakage.
¡ Ventilate the work area when refrigerant leaks during the operation.
Coming in contact with fire, refrigerant could generate toxic gas.
¡ Confirm after the foundation construction work that refrigerant does not leak.
If coming in contact with fire of a fan heater, a stove or movable cooking stove, etc., refrigerant leaking in the
room could generate toxic gas.
CAUTION
¡ Execute proper grounding. Do not connect the ground wire to a gas pipe, water pipe, lightning rod or a telephone
ground wire.
Improper placement of ground wires can result in electric shock.
¡ The installation of an earth leakage breaker is necessary depending on the established location of the unit.
No installing an earth leakage breaker may result in electric shock.
¡ Do not install the unit where there is a concern about leakage of combustible gas.
The rare event of leaked gas collecting around the unit could result in an outbreak of fire.
¡ For the drain pipe, follow the installation manual to insure that it allows proper drainage and thermally insulate it
to prevent condensation. Inadequate plumbing can result in water leakage and water damage to interior items.

6.2 Servicing
(1) Evacuation
The evacuation is an procedure to purge impurities ...... noncondensable gas, air, moisture from the refrigerant equipment by using
a vacuum pump. Since the refrigerant R22 is very insoluble in water, even a small amount of moisture left in the refrigerant
equipment will freeze, causing what is called water clogging.
¡ Evacuation procedure
(a)
Check to ensure that there is no internal pressure in the unit. If there is an internal pressure, it
should be relieved through the check joint.
(b)
Connect the service hoses of the gauge manifold to the check joint of the gas & liquid piping.
(c)
Connect a vacuum pump to the charge hose A . Repeat evacuation in the following sequence.
Liquid side
Start the vacuum pump
Gas side
Operate the vacuum pump for more than 15 minutes after –0.1MPa
(–76 cmHg) is indicated.
Check joint
Close low pressure valve 1 of gauge manifold.
Service hose
Gauge
manifold
Stop the vacuum pump.
Charge hose
Notes (1) Do not use the refrigerant pressure to expel air.
(2) Do not use the compressor for evacuation.
(3) Do not operate the compressor in the vacuum condition.

Refrigerant
cylinder
(2) Refrigerant charge
(a)
Discharge refrigerant entirely from the unit and evacuate the unit.
(b)
Keep the gauge manifold and connect a refrigerant cylinder to the unit.
Note: Addition of refrigerant without evacuation is unreasonable, because it will result in low charge or overcharge.
(c)
Record the weight of the refrigerant cylinder on the balance. This is necessary for making sure of the charged refrigerant
amount.
(d)
Purge air from the charge hose A .
Firstly loose the connecting portion of the charge hose A at the gauge manihold side and open the valve 3 for a few seconds,
and then immediately retighten it after observing that gas is blow out from the loosened portion.
(e)
Open the valve 1 and 3 after discharging air from the charge hose A , then the gas refrigerant begins flowing from the
cylinder into the unit. Be sure to erect the refrigerant cylinder upright to let gas refrigerant flow into the unit.
(f)
When refrigerant has been charged into the system to some extent, refrigerant flow becomes stagnant, when that happens,
start the compressor in cooling cycle until the unit is filled with gas to the specified weight.
(g)
Making sure of the refrigerant amount, close the valve 3.
(h)
Disconnect the charge hose from the unit. Cover the valve ports of the refrigerant piping with caps and tighten them securely.
(i)
Check for gas leakage applying a gas leak detector along the piping line.
(j)
Start the air conditioner and make sure of its operating condition ...... high side and low side pressures and temperature
difference between suction air and outlet air.
6.3 Power supply remote operation
When the remote part on indoor unit PCB is modified, the air conditioner is turned ON-OFF by power supply ON-OFF operation
without using remote control switch.
After the power supply remote operation, the operation contents can be modified by the remote controller.
