1 SAFETY PRECAUTION

1-1. ALWAYS OBSERVE FOR SAFETY

Before obtaining access to terminal, all supply circuits must be disconnected.

1-2. CAUTIONS RELATED TO NEW REFRIGERANT

Cautions for units utilizing refrigerant R410A

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.

	Tools for R410A
Gauge manifold		Vacuum pump adaptor
Charge hose		Electronic refrigerant
Gas leak detector		charging scale
Torque wrench

Keep 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.

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

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.

[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.

[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. (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 specifications. (UNF1/2)
		·Use high-tension side pressure of 5.3 MPa·G or over.
2	Charge hose	·Only for R410A
		·Use pressure performance of 5.09 MPa·G or over.
3	Electronic scale
4	Gas leak detector	·Use the detector for R134a, R407C or R410A.
5	Adaptor for reverse flow check	·Attach on vacuum pump.
6	Refrigerant charge base
7	Refrigerant cylinder	·Only for R410A Top of cylinder (Pink)
		Cylinder with syphon
8	Refrigerant recovery equipment

1-4. PRECAUTIONS FOR SALT PROOF TYPE "-BS" MODEL

Although "-BS" model has been designed to be resistant to salt damage, observe the following precautions to maintain the performance of the unit.

1.Avoid installing the uint in a location where it will be exposed directly to seawater or sea breeze.

2.If the cover panel may become covered with salt, be sure to install the unit in a location where the salt will be washed away by rainwater. (If a sunshade is installed, rainwater may not clean the panel.)

3.To ensure that water does not collect in the base of the outdoor unit, make sure that the base is level, not at angle. Water collecting in the base of the outdoor unit could cause rust.

4.If the unit is installed in a coastal area, clean the unit with water regularly to remove any salt build-up.

5.If the unit is damaged during installation or maintenance, be sure to repair it.

6.Be sure to check the condition of the unit regularly.

7.Be sure to install the unit in a location with good drainage.

*1.A breaker with at least 3.0 mm contact separation in each poles shall be provided. Use earth leakage breaker (NV). *2.Max. 80 m

*3.The gures are NOT always against the ground.

S3 terminal has DC 24 V against S2 terminal. However between S3 and S1, these terminals are NOT electrically insulated by the transformer or other device.

Notes: 1. Wiring size must comply with the applicable local and national codes.

2.Power supply cables and the cables between Controller and Outdoor unit shall not be lighter than polychloroprene sheathed flexible cables.

(Design 60245 IEC 57)

3.Be sure to connect the cables between Controller and Outdoor unit directly to the units (no intermediate connections are allowed).

Intermediate connections may result in communication errors. If water enters at the intermediate connection point, it may cause insufficient insulation to ground or a poor electrical contact .

(If an intermediate connection is necessary, be sure to take measures to prevent water from entering the cables.)

4.Install an earth longer than other cables.

Warning:

In case of A-control wiring,

there is high voltage potential on the S3 terminal caused by electrical circuit design that has no electrical insulation between

power line and communication signal line. Therefore, please turn off the main power supply when servicing. And do not touch the S1, S2, S3 terminals when the power is energized. If isolator should be used between Interface unit/Flow temp. controller and outdoor unit, please use 3-pole type.

8 TROUBLESHOOTING

8-1. TROUBLESHOOTING

<Error code display by self-diagnosis and actions to be taken for service (summary)>

Present and past error codes are logged and displayed on the control board of outdoor unit. Actions to be taken for service, which depends on whether or not the trouble is reoccurring at service, are summarized in the table below. Check the contents below before investigating details.

	Unit conditions at service	Error code	Actions to be taken for service (summary)
		Displayed	Judge what is wrong and take a corrective action according
			to “8-3. Self-diagnosis action table”.
	The trouble is reoccurring.
		Not displayed	Conduct troubleshooting and ascertain the cause of the
			trouble.
			Consider the temporary defects such as the work of
			protection devices in the refrigerant circuit including
			compressor, poor connection of wiring, noise and etc.
			Re-check the symptom, and check the installation
			environment, refrigerant amount, weather when the
		Logged	trouble occurred, matters related to wiring
			and etc.
			Reset error code logs and restart the unit after finishing
			service.
	The trouble is not reoccurring.		There is no abnormality in electrical component,
			controller board, and etc.
			Re-check the abnormal symptom.
			Conduct troubleshooting and ascertain the cause of the
		Not logged	trouble.
			Continue to operate unit for the time being if the cause
			is not ascertained.
			There is no abnormality concerning of parts such as
			electrical component, controller board, and etc.

8-2. CHECK POINT UNDER TEST RUN

Before test run

•After installation of outdoor units, piping work and electric wiring work, re-check that there is no water leakage, loosened connections and incorrect polarity.

•Measure impedance between the ground and the power supply terminal block (L, N) on the outdoor unit by 500 V Megger and check that it is 1.0 M or over.

•Turn on power supply 12 hours before test run in order to protect compressor.

•Make sure to read operation manual before test run. (Especially items to secure safety.)
