SAFETY PRECAUTION

Cautions for units utilizing refrigerant R410A

CAUTIONS RELATED TO NEW REFRIGERANT

Use new refrigerant pipes.

Make sure that the inside and outside of refrigerant piping is clean and it has no contamination such as sulfur hazardous for use, oxides, dirt, shaving particles, etc. In addition, use pipes with specified thickness.

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.

In case of using the existing pipes for R22, be careful with the followings.

· Change flare nut to the one provided with this product. Use a newly flared pipe.

· Avoid using thin pipes.

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 enter 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.

Tools for R410A

Contamination inside refrigerant piping can cause deterioration of refrigerant oil etc.

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

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

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

[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 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 stood vertically. (Refr igerant is charged from liquid phase.)

FUNCTION OF SWITCH ON INDOOR CIRCUIT BOARD

[1] Before test run

The test run can be carried out either from the outdoor unit or the indoor unit.

1. Check list

• After the installation, piping setup,and wiring of the indoor and outdoor units is complete, check that refrigerant is not leaking, the power and control wires are not loose, and the poles are not reversed.

• Use a 500 V insulation resistance tester to make sure that the resistance between the power terminal and the ground is 1.0 M or more. If it is less than 1.0 M, do not operate the unit. *Absolutely do not touch the tester to indoor/outdoor connection terminals S1, S2, and S3. An accident could occur.

• Make sure there is no malfunction in the outdoor

unit. (If there is a malfunction, y ou can diagnose it using LED2 on the

board.)

• Check that the ball valve is fully open on both the liquid and gas ends.

• Check the electrical power phase. If the phase is reversed, the fan may rotate in the wrong direction or stop, or

unusual sounds may be produced.

• Starting at least 12 hours before the test run,send current through the crankcase heater. (If the current is running f or a shorter period of time, damage to the compressor could result.)

• For specific models requiring changing of settings for higher ceilings or selection of power supply ON/OFF capability, make proper changes referring to the description for Selection of Functions through Remote Controller.

After the above checks are complete, carry out the test run as indicated in the following outline.

[2] Test run procedures

1. Indoor unit

Operating procedures

(1) Turn on the main power supply

While the room temperature display on the remote controller reads “CENTRALLY CONTROLLED”, the remote controller is disabled.Turn off the “CENTRALLY CONTROLLED” display before using the remote controller.

(2) Press “TEST RUN” button twice

(A) The ‘TEST RUN’ indicator should light up.

(3) Press button

Cooling/drying mode : Cool air should start to blow. Heating mode : Warm air should start to blow (after a while).

(4) Check the outdoor unit fan for correct running

The outdoor unit features automatic capacity control to provide optimum fan speeds. The fan keeps running at a low speed to meet the current outside air condition unless it exceeds its available maximum power. Then, in actuality, the fan may stop or run in the reverse direction depending on the outside air, which does not mean malfunction.

(5) Press the “ON/OFF” button to reset the test run in progress

• The test run will be automatically shut down after two hours in response to the AUTO STOP setting of two hours on the timer.

•

During the test run, the room temperature display shows the indoor unit tubing temperatures.

CHECK TEST

• In the case of the test run, the OFF timer will activate, and the test run will automatically stop after two hours.

• The room temperature display section shows the control temperature for the indoor units during the test run.

• Check that all the indoor units are running properly for simultaneous twin and triple operation.

Malfunctions may not be displayed even if the wiring is incorrect.

(*1) After turning ON the power,the system will go into startup mode,and the remote controller operation lamp (red) and the room temperature display section’s “H0 ” will flash. Also, in the case of the indoor substrata LEDs, LED 1 and LED 2 light up (when address is 0) or become dim (when address is not 0), and LED 3 flashes. In the case of the outdoor substrata LED display, – and – are displayed alternatively at 1-second intervals.

• If one of the above operations does not function correctly, the following causes should be considered, and if applicable, dealt with. (The following symptoms have been determined under test run mode. Note that “startup” in the chart means the *1 display above.)

Remote controller is displaying “H0”, and operation is not possible.

After power is turned ON,“H0 ” is displayed for 3 mins., then error code is displayed.

Power is turned ON,and “EE” or “EF” are displayed after “H0” is displayed.

Display messages do not appear even when remote controller operation switch is turned ON (operation lamp does not light up).

Operation display appears but soon disappears even when remote controller operations are executed.

After “startup” display,“00” is displayed (correct operation).

After “startup” display,error code is displayed.

After “startup” display, “F1” (negative phase) is displayed.

After “startup” display, “00” or “EE” is displayed (“EE” is displayed when a test run is made).

After “startup” display, “EA” (error for number of units) or “Eb” (unit number error) is displayed.

After “startup” display , “00” is displayed (correct operation).

• After power is turned ON, system star tup lasts for about 2 mins., and “H0” is displayed (correct operation).

• Outdoor unit ’s safeguard installation connector is open.

• Negative phase and open phase of outdoor unit’s power

terminal board. (Single phase: L, N, /triple phase: L1, L2, L3, N, )

• Incorrect connection of outdoor ter minal board (Single phase: L, N, /triple phase: L1, L2, L3, N, grounding and S1, S2, S3)

• Outdoor unit and indoor unit construction differ.

• Wiring for the indoor and outdoor unit is not connected

correctly. (Polarity is wrong for S1, S2, S3)

• Remote controller transmission wire short.

• There is no outdoor unit for address 0 (address is

something other than 0).

• Remote controller transmission wire burnout.

• After cancellation of function selection, operation is not

possible for about 30 secs. (correct operation).

(1) Check Items

• After installation of indoor and outdoor units,and piping and electric wiring work,check that the unit is free from leaks of refrigerant,loosened connections,and incorrect polarity.

• Check that there is no negative phase and open phase. (The F1 message for negative phase and the F2 message for open phase will flash at LED 1 on the outdoor substrate. If this happens,rewire correctly.)

• Measure the impedance between power terminals (Single phase: L, N, /triple phase: L1, L2, L3, N, ) and the ground with a 500 V Megger and check that it is 1.0 M or more. Do not operate the equipment if measurement is less than 1.0 M. *Never conduct this operation on the outdoor connection wiring terminals (S1, S2, S3) as this causes damage.

• When there is no error at the outdoor unit. (If there is an error at the outdoor unit, it can be evaluated at LED 1 [digital display] of the outdoor substrate.)

• The stop valves are open both the liquid and gas sides. After checking the above, execute the test run in accordance with the following.

(2) Test run start and finish

• Operation from the indoor unit Execute the test run using the installation manual for the indoor unit.

• Operation from the outdoor unit Execute settings for test run start,finish and operation mode (cooling, heating) using the DIP switch SW 4 on the outdoor substrate.

a) Set the operation mode (cooling, heating) using SW 4-2 b) Turn ON SW 4-1, The operation mode for SW 4-2 will be adhered to, and the test run will commence c) Turn OFF SW 4-1 to finish the test run

• There may be a faint knocking noise emitted from the proximity of the fan during the test run. This is torque fluctuation occurring due to control of fan revolutions. There is no problem with the product.

Note: The SW 4-2 operation mode cannot be changed during the test run. (To change test run mode, stop the equipment with SW 4-1, change the operation mode, then restart test run with SW 4-1.)

• If the 2-hour timer is set,the test run will stop automatically after 2 hours.

• During the test run,the room temperature display on the indoor unit will indicate the temperature of the indoor unit

piping.

1. First, check the electricity current marker

If the correct voltage (DC 12 V)is not displayed on the remote controller, the electric current marker will be lit. If the electricity current marker is not lit, check the remote controller wiring and the indoor unit.

(1) Electric current marker

2. Transfer to remote control mode

Hold down the CHECK button for five seconds or more to display the diagram on the left. Press the FILTER button to commence diagnosis of remote controller.

3. Remote controller diagnosis results

(1)The remote control is functioning correctly.

Check other possible causes as there are no problems with the remote controller.

(2) The remote controller has a nonconformity.

The remote controller must be replaced. Error display 1 (“NG”) flashes to show a nonconformity in the transmitter-receiver circuit.

Potential problems other than those diagnosed for the remote controller.

(1) Single transmission not possible if error display 2 (“E3”)

flashes. There is “noise” on the transmission line, or damage of other remote controllers for the indoor units can be considered. Check the transmission path and other controllers.

(2) Data error has occurred when error display three shows

“ERC” and number of data errors. Number of generated data errors (maximum 66 errors). The number of generated data errors stands for the difference in the number of bits of transmitted data from the remote controller and the actual number of bits that were transmitted along the transmission path. If this error occurs, “noise”, etc., is interfering with the transmission data. Check the transmission path.
