1 SAFETY PRECAUTION

[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.

Cautions for units utilizing refrigerant R407C

CAUTIONS RELATED TO NEW REFRIGERANT

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 enter, 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 witha flame, poisonous gases will be released.

Cautions for units utilizing refrigerant R410A

Store the piping to be used during installationindoors 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 gascylinder.

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 refrige-rant 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 enter into refrigerant cycle, that cancause deterioration of refrigerant oil or malfunction of com-pressor.

Do not use a charging cylinder.

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

[1] Cautions for service(1) Perform service after collecting 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 chargeWhen charging directly from cylinder· Check that cylinder for R410A on the market is syphon type.· Charging should be performed with the cylinder of syphon stood vertically. (Refrigerant is charged from liquid phase.)

NOTES :1. When servicing, electrical parts box may be disassembled.

Make the wires loose enough when connecting heater power supply wire, remote controller wire, and indoor/outdoor unit connecting wire.

2. Detaching corner panel makes it possible to adjust the height of body with the grille attached.

3. Caution for attaching optional Muliti function casement and optional High efficiency filter : 1) Space behind the ceiling shall be high enough as specified

in the table below.

2) Add extra 135mm to the dimensions of w in the figure.3) Mount both High efficiency filter and Multi function casement together.

4. When connecting branch duct, be sure to insulate the heat.(Otherwise, it causes dew to from or drop.)

The output pulse shifts in above order.❈ 1. When linear expansion valve operation stops, all output phase

become OFF.2. At phase interruption or when phase does not shift in order,

motor does not rotate smoothly and motor will locks and vibrates.

❈ When the switch is turned on, 2200 pulse closing valve signalwill be send till it goes to point A in order to define the valve position.

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

❈ Noise can be detected by placing the ear against the screw driver handle while putting the screw driver tip to the linearexpansion valve.

Symptom Check points

Operation circuit fail-ure of the microprocessor.

Disconnect the connector on the controller board, then con-nect LED for checking.

When power is turned on, pulse signals will output for 10 sec-onds. There must be some defects in the operation circuit ifthe LED does not light while the signals are output or keepslighting even after the signals stop.

Countermeasures

Exchange the indoor con-troller board at drive circuitfailure.

Linear expansionvalve mechanism islocked.

Valve doesn't closecompletely.

Wrong connection ofthe connector orcontact failure.

To check the linear expansion valve, operate the indoor unitin fan mode and at the same time operate other indoor unitsin cooling mode, then check the pipe temperature of the indoor unit by theoutdoor multi controller board operationmonitor. During fan operation, linearexpansion valve is closed completely and ifthere is any leaking, detecting temperatureof the thermistor will go lower. If the detect-ed temperature is much lower than the tem-perature indicated in the remote controller,

it means the valve is not closed all the way. It is not neces-sary to exchange the linear expansion valve, if the leakage issmall and not affecting normal operation.

Thermistor(Liquid pipe)

Linearexpansionvalve

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

Check the color of lead wire and missing terminal of the con-nector.

Exchange the linearexpansion vale.

Exchange the linearexpansion valve.

If large amount of thermis-tor is leaked, exchange thelinear expansion valve.

Disconnect the connectorat the controller board,then check the continuity.

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

Short or breakage ofthe motor coil of thelinear expansionvalve.

✽ Ceiling height can be changed depends on SWB setting.

Address setting should be done when M-NET Remote controller is being used.

When attach the optional high performance filter elements (multi function casement) tothe unit, be sure to attach it to the optionside in order to prevent the airflow reducing.

This is the switch to be used when the indoorunit is operated with R2 series outdoor unit as a set.

If the unit is used at the 230V or 240V area, set the voltage to 240V.If the unit is used at the 220V, set the voltage to 220V.
