Cautions for units utilizing refrigerant R410A

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.

Handle tools with care.

If dirt, dust or moisture enters 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.

Electronic refrigerant charging scale

Vacuum pump adaptorSize adjustment gauge

Gauge manifold

Torque wrenchGas leak detectorCharge hose

Tools for R410A

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

If large amount of mineral oil enters, that can cause deterio-ration of refrigerant oil, etc.

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.

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

The refrigerant oil applied to flare and flangeconnections must be ester oil, ether oil or alkylbenzene oil in a small amount.

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

Never use any refrigerant other than that specified.Doing so may cause a burst, an explosion, or fire when the unit is being used, serviced, or disposed of.Correct refrigerant is specified in the manuals and on the spec labels provided with our products.We will not be held responsible for mechanical failure, system malfunction, unit breakdown or accidents caused by failure to follow the instructions.

Use the specified refrigerant only.

2 SAFETY PRECAUTION

OCH413E

55

[1] Cautions for service(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 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.)

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 sent 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.

Symptom Check points

Operation circuit failure of the micro processor

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

When power is turned on, pulse signals will be 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.

Countermeasures

Exchange the indoor con-troller board at drive circuit failure.

Linear expansion valve mechanism is locked.

Valve does not close completely.

Wrong connection of the connector or contact failure

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 of the indoor unit by the outdoor multi controller board operation monitor. During fan operation, linear expan-sion 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 tem-perature indicated in the remote controller, 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.

Thermistor(Liquid pipe)

Linearexpansionvalve

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

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

Exchange the linear expan-sion valve.

Exchange the linear expan-sion valve.

If large amount of refriger-ant is leaked, exchange the linear expansion valve.

Disconnect the connector at the controller board, then check the continuity.

Measure the resistance between each coil (white-red, yellow-brown, orange-red, blue-brown) with a tester. It is normal if the resistance is in the range of 200Ω ±10%.

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