Do not use the existing refrigerant piping.

The old refrigerant and lubricant in the existing piping
contains a large amount of chlorine which may cause the
lubricant deterioration of the new unit.

Use “low residual oil piping”

If there is a large amount of residual oil (hydraulic oil, etc.)
inside the piping and joints, deterioration of the lubricant
will result.

Use ESTR , ETHER or HAB as the lubricant to
coat flares and flange connection parts.

If large amount of mineral oil enters, that can cause
deterioration of refrigerant oil etc.

Use liquid refrigerant to charge the system.

If gas refrigerant is used to seal the system, the composition
of the refrigerant in the cylinder will change and performance
may drop.

Do not use a refrigerant other than R407C.

If another refrigerant (R22, etc.) is used, the chlorine in the
refrigerant may cause the lubricant deterioration.

Use a vacuum pump with a reverse flow check valve.

The vacuum pump oil may flow back into the refrigerant
cycle and cause the lubricant deterioration.

Store the piping to be used during installation
indoors with keep both ends sealed until just
before brazing.
(Store elbows and other joints in a plastic bag.)

If dust, dirt, or water enters the refrigerant cycle,
deterioration of the oil and compressor trouble may result.

Ventilate the room if refrigerant leaks during
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.

SAFETY PRECAUTION

CAUTIONS RELATED TO NEW REFRIGERANT

Cautions for units utilizing refrigerant R407C

[1] Cautions for service

·After recovering the all refrigerant in the unit, proceed to working.

·Do not release refrigerant in the air.

·After completing the repair service, recharge the cycle with the specified amount of
liquid refrigerant.

[2] Refrigerant recharging

Gravimeter

Unit

(1) Refrigerant recharging process

1Direct charging from the cylinder

·R407C cylinder which is available on the market has a syphon pipe.

·Leave the syphon pipe cylinder standing and recharge it.
(By liquid refrigerant)

(2) Recharge in refrigerant leakage case

·After recovering all the refrigerant in the unit, proceed to working.

·Do not release the refrigerant in the air.

·After completing the repair service, recharge the cycle with the specified amount of
liquid refrigerant.

[3] Service tools

Use the below service tools as exclusive tools for R407C refrigerant.

No. Tool name Specifications

1 Gauge manifold ·Only for R407C

·Use the existing fitting SPECIFICATIONS. (UNF7/16)

·Use high-tension side pressure of 3.43MPa·G or over.

Cautions for units utilizing refrigerant R410A

Store the piping to be used during installation
indoors and keep both ends of the piping sealed
until just before brazing. (Leave elbow joints, etc.
in their packaging.)

Use ester oil, ether oil or alkylbenzene oil (small
amount) as the refrigerant oil applied to flares
and flange connections.

Charge refrigerant from liquid phase of gas
cylinder.

If the refrigerant is charged from gas phase, composition
change may occur in refrigerant and the efficiency will be
lowered.

Do not use refrigerant other than R410A.

If other refrigerant (R22 etc.) is used, chlorine in refrige­rant can cause deterioration of refrigerant oil etc.

Use a vacuum pump with a reverse flow check
valve.

Vacuum pump oil may flow back into refrigerant cycle and
that can cause deterioration of refrigerant oil etc.

Use the following tools specifically designed for
use with R410A refrigerant.

The following tools are necessary to use R410A refrigerant.

Keep the tools with care.

If dirt, dust or moisture enters into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of com­pressor.

Do not use a charging cylinder.

If a charging cylinder is used, the composition of refrigera­nt will change and the efficiency will be lowered.

The old refrigerant and lubricant in the existing piping
contains a large amount of chlorine which may cause the
lubricant deterioration of the new unit.

[1] Cautions for service

Gravimeter

Unit

(1) Perform service after recovering the refrigerant left in unit completely.
(2) Do not release refrigerant in the air.
(3) After completing service, charge the cycle with specified amount of refrigerant.
(4) When performing service, install a filter drier simultaneously.

Be sure to use a filter drier for new refrigerant.

[2] Additional refrigerant charge

When charging directly from cylinder

· Check that cylinder for R410A on the market is syphon type.

· Charging should be performed with the cylinder of syphon standing vertically. (Refrigerant is charged from liquid phase.)

[3] Service tools

Use the below service tools as exclusive tools for R410A refrigerant.

No. Tool name Specifications

1 Gauge manifold ·Only for R410A

·Use the existing fitting

·Use high-tension side pressure of 5.3MPa·G or over.

Linear expansion valve

① Operation summary of the linear expansion valve

• Linear expansion valves open/close through the use of a stepping motor after receiving the pulse signal from the indoor
controller board.

• Valve position can be changed in proportion to the number of pulse signals.

<Connection between the indoor controller board and the linear expansion valve>

Note : Since the number of the connector at the controller board side and the relay connector are different, follow the color of

the lead wire.

The output pulse shifts in above order.

• When linear expansion valve operation stops, all output phase
become OFF.

• At phase interruption or when phase does not shift in order, motor
does not rotate smoothly and motor will lock and vibrate.

• When the switch is turned on, 2200 pulse closing valve signal will be
send till it goes to point

A in order to define the valve position.

• When the valve moves smoothly, there is no sound or vibration
occurring from the linear expansion valves : however, when the
pulse number moves from E to A or when the valve is locked, more
sound can be heard than in a normal situation.

• Sound can be detected by placing the ear against the screw driver
handle while putting the screw driver tip to the linear expansion
valve.

Troubleshooting

➂

Symptom

Operation circuit fail­ure of the micro
processor

Linear expansion
valve mechanism is
locked.

Short or breakage of
the motor coil of the
linear expansion
valve

Valve doesn't close
completely.

Wrong connection of
the connector or
contact failure

Check points

Disconnect the connector on the controller board, then con­nect LED for checking.

When power is turned on, pulse signals will output for 10 sec­onds. There must be some defects in the operation circuit if
the LED does not light while the signals are output or keeps
lighting even after the signals stop.

Motor will idle and make a ticking noise when the motor is
operated while the linear expansion valve is locked. This
ticking sound is the sign of the abnormality.

Measure the resistance between each coil (white-red, yellow­brown, orange-red, blue-brown) with a tester. It is normal if
the resistance is in the range of 150Ω ±10%.

To check the linear expansion valve, operate the indoor unit
in fan mode and at the same time operate other indoor units
in cooling mode, then check the pipe temperature <liquid

it means the valve is not closed all the way. It is not neces­sary to exchange the linear expansion valve, if the leakage is
small and not affecting normal operation.

Check the color of lead wire and missing terminal of the con­nector.

pipe temperature> of the indoor unit by the
outdoor multi controller board operation
monitor. During fan operation, linear
expansion valve is closed completely and if
there is any leaking, detecting temperature
of the thermistor will go lower. If the detect­ed temperature is much lower than the tem­perature indicated in the remote controller,
