1-1 EXECUTION PROCEDURE AND EXECUTION PRECAUTIONS

Before execution

Execution zone decision

Confirmation of refrigerant used

Preparation of execution drawings

Confirmation of installation site

Preparations before execution

Execution

Sleeve and insert work

Indoor unit installation

Refrigerant piping work

Drain piping work

Duct work

Heat insulation work

Electrical work

Foundation work for products

Execution procedure and precautions Reason

Check the characteristics of the refrigerant used and grasp the

1

special features of the refrigerant. If refrigerant must be charged, always charge the refrigerant specified for the product. Confirm the product design pressure.

2

R410A 609psi (4.20MPa)

Use new refrigerant piping of the thickness specified by the

1

D&T manual. Since R410A dedicated tools are necessary, prepare them

2

in advance. Absolutely avoid use of existing piping. If use of existing

3

piping is unavoidable, the piping must be cleaned.

Always use a level and keep the indoor unit level. If the equipment is tilted toward the drain port, install it so that the tilt is within 10mm. Excessive tilt will cause water leakage.

When performing piping work, observe the following items so that the inside of the piping is clean and air tight.

Use pipe that is not dirty inside.

1

When the pipe is left standing, protect it.

2

Finish flaring exactly.

3

Confirm the width across flats dimension and shape of flare nuts.

4

Always blow nitrogen while brazing.

5

Perform flushing before connecting the equipment.

6

Always make the downward slope of the drain pipe 1/100 or

1

greater and make the horizontal length within 66ft.(20m). Use hard polyvinylchloride pipe as the drain pipe.

2

Support the drain pipe between

3

Use pipe of 1 rank up (VP30 or greater) as central piping.

4

Select the size of the heat insulating material according to the ambient temperature and relative humidity of the refrigerant. Use a heat insulating material having a heat conductivity of 0.043W/

.

(m

k) or less.

59-1/16 in(1.5m) to 6-3/4 in ( 2.0m).

Use of a refrigerant other than the specified refrigerant will invite equipment trouble.

Secure the necessary pressure resistance.

Prevention of water leakage

Foreign matter, water, etc. in the piping will cause faulty cooling and compressor trouble. Refrigerant leakage will cause low performance and abnormal stopping.

Prevention of water leakage

Products installation work

*Refer to warning or caution in the attached installation manual of each products

Refrigerant piping connection work

Air tightness test

Vacuum drying

When making flare connections always use a torque wrench and tighten the flare nut positively to the specified torque.

Pressurize the product with nitrogen gas up to the design pressure and conduct a 24Hr air tightness test.

1

2

3

*

Refrigerant leakage will cause low performance and abnormal stopping.

Install a vacuum pump with reverse flow check mechanism or a reverse flow check adaptor to a conventional vacuum pump and use. Pump down sufficiently. Approximately 1 hour or longer after Allow to stand for approximately 1 hour after stopping the vacuum pump and confirm that the needle does not return. Air purging using refrigerant is strictly prohibited.

500 micron (-100.7kPa) reached.

Mixing in of vacuum pump oil by reverse flow will cause equipment trouble.

Prevents degradation of the oil by completely removing water and air.

recommend the vacuuming

*

mode

Vacuuming mode

This function is used for vacuuming the indoor unit and the connection piping.

Note: For starting Vacuuming mode, the refrigerant address setting has to be finished.

When the [vacuuming mode] is set, <Push switch setting, F3:21> EEV of connected all indoor units opens. So, the vacuuming indoor unit and piping becomes easier.

When the vacuuming ends, please turn off the power supply for all of the indoor units, RB units and outdoor unit, [vacuuming mode] is released.

Execution

Addition refrigerant charging

Gas leak test

Pre-commisioning

"Before Power ON"

Pre-commisioning

"After Power ON"

Confirm the additional refrigerant amount with the installation

1

manual, etc. Always take the R410A refrigerant from the cylinder liquid phase

2

and charge it using the gas phase. (Do not lay a cylinder with siphon pipe on its side.)

3

Use an R410A dedicated gauge manifold and charging hose.

Use an R410A dedicated leak tester to check for gas leaks.

Power source installation inspection

Field setting and setting inspection

Transmission wire installation inspection

Connect Service Tool

Power source inspection

2

Error indication inspection

3

Transmission wire connection inspection

Other Field setting with power ON state, and adjustment

If taken from the air phase, since the composition of the refrigerant which is charged will change, low performance and abnormal stop will occur easily. Prevent erroneous sealing in of refrigerant.

A leak tester for other than R410A cannot detect leaks.

Before starting the installed system, the final inspection is necessary. When you find out any incorrect install ation or wrong setting, revise it before starting the system

When you see any abnormal things, turn OFF the power supply first, and revise it with power OFF state.

In case of "Auto Address setting"

Note :

Test run & adjustment

Handover & explanation of operation

Check operating condition by using service tool. For the judgment of operating condition, refer to the operation check sheet.

Perform the auto address setting of Signal amp. at first, and the next perform the auto address setting of indoor unit. When you perform the autoaddress setting for RB unit, the indoor unit address setting needs to be done at first.

When you see any abnormal things, stop the system, and revise it with power OFF state.

Overview of system operation check procedure

Step-1: Connect Service Tool PC to the VRF VR-II system.

Do scaning of refrigerant system which should be commissioned.

Step-2: Compare the number of installed units (OU, RB Group and IU) with the System List data obtained from the Service Tool.

Step-3: Operate all Indoor Units under Test Mode Cooling (Select Test mode either cool or heat based on ambient temperature.).

Step-3-1: During operation, check the RB unit SV status and IU thermistor value Step-3-2: After 1-hour operation, check the Refrigerant System

Step-4: After 1-hour Test run operation (excluding special operation), Step-4-1: Switching the operation mode of IU, in order of RB group number, from cool to heat.

- Check the RB unit SV status and IU thermistor value Step-4-2: When all IUs run under heating, continue operation minimum 15min. And check the Refrigerant system
