1. TEST RUN
Sleeve and insert work
Indoor unit installation
Refrigerant piping work
Drain piping work
Duct work
Heat insulation work
Electrical work
Foundation work for products
Refrigerant piping connection work
Air tightness test
Vacuum drying
Check the characteristics of the refrigerant used and grasp the special features of the refrigerant. If refrigerant must be charged, always charge the refrigerant specified for the product. Confirm the product design pressure. R410A 4.2 MPa
Use new refrigerant piping of the thickness specified by the D&T manual. Since R410A dedicated tools are necessary, prepare them in advance. Absolutely avoid use of existing piping. If use of existing piping is unavoidable, the piping must be cleaned.
Use of a refrigerant other than the specified refrigerant will invite equipment trouble.
Secure the necessary pressure resistance.
Use pipe that is not dirty inside. When the pipe is left standing, protect it. Finish flaring exactly. Confirm the width across flats dimension and shape of flare nuts. Always blow nitrogen while brazing. Perform flushing before connecting the equipment.
Always make the downward slope of the drain pipe 1/100 or greater and make the horizontal length within 20m. Use hard polyvinylchloride pipe as the drain pipe. Support the drain pipe between 1.5 to 2.0m. Use pipe of 1 rank up (VP30 or greater) as central piping.
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
Prevention of water leakage
Refrigerant leakage will cause low performance and abnormal stopping.
Refrigerant leakage will cause low performance and abnormal stopping.
Mixing in of vacuum pump oil by reverse flow will cause equipment trouble. Prevents degradation of the oil by completely removing water and air.
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.
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.
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.
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 -0.10MPa reached. 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.

Vacuuming mode
This function is used for vacuuming the indoor unit and the connection piping.
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, and outdoor unit, [vacuuming mode] is released.
*
recommend the vacuuming mode
*
Products installation work
*Refer to warning or caution in the attached installation manual of each products
Note: For starting Vacuuming mode, the refrigerant address setting has to be finished.
01-02
Execution
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 the indoor unit address setting needs to be done at first.
Pre-commisioning
"Before Power ON"
Gas leak test
Use an R410A dedicated leak tester to check for gas leaks.
1
2
3
Confirm the additional refrigerant amount with the installation manual, etc. Always take the R410A refrigerant from the cylinder liquid phase and charge it using the gas phase. (Do not lay a cylinder with siphon pipe on its side.) Use an R410A dedicated gauge manifold and charging hose.
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.

Overview of system operation check procedure
Step-1: Connect Service Tool PC to the VRF V-III system.
Do scaning of refrigerant system which should be commissioned.
Step-2: Compare the number of installed units (OU 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 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 from cool to heat.
- Check the IU thermistor value Step-4-2: When all IUs run under heating, continue operation minimum 15min. And check the Refrigerant system

*1: Auto restart is an emargency function such as for power failure etc. Do not start and stop the indoor unit by this function in normal operation. Be sure to operate by the control unit, converter or external input device. *2: Select control conditions of external output. "Mode 00" is output when heating thermostat is ON, "Mode 01" is output in heating operation, "Mode 02" is output in heating operation and in fan operation.
