Remove Dirt or Water in the Piping

Make sure there is no any dirt or water before connectiong the piping to the outdoor units. Wash the piping with high pressure nitrogen, never use refrigerant of outdoor unit.

Airtight Test

Air tightness test nitrogen must be used. (See the fgure on the right for the location of the maintenance access. Increase the pressure from the liquid pipe and gas pipe to 4.0 MPa at the same time not exceeding 4.0 MPa. If the pressure does not drop in 24 hours, the test is passed. When the pressure drops, check the leakage position (after you make sure that there is no leakage, discharge the nitrogen.

CAUTION
Never use oxygen, combustible gas, or poisonous gas in the air tightness test. To prevent damage to the equipment, the pressure must not be held for too long.

Air Purge with Vacuum Pump

Use a vacuum pump that can evacuate the pipe to the pressure of less than -100.7 kPa (5 Torr, -755mmHg). When the pump is stopped, do not let the pump oil fow back into the refrigerant pipe. The liquid and gas pipes should be evacuated with a vacuum pump for more than two hours to the pressure of less than 100.7kPa. Then, place the pipes with the pressure of less than 100.7 kPa for more than one hour, and check whether the reading of the vacuum gauge rises. (If the reading rises, there is residual water or gas leakage in the system. The leakage must be checked and solved and the test should be performed again. Water may enter into pipes in the following conditions: the installation is carried out in rainy seasons and the installation period is long; the pipes are condensed inside; rainwater enters the pipes. After the above vacuum drying of two hours, use nitrogen to increase the pressure to 0.05 MPa (vacuum breaking), and use a vacuum pump to decrease the pressure to lower than -100.7kPa or below and hold the pressure for one hour vacuum drying. If the pressure cannot be decreased to lower than -100.7 kPa after two-hour vacuumizing, repeat the vacuum breaking and vacuum process.) After that, place the vacuum pipes for one hour, and then check whether the reading of the vacuum gauge rises.

CAUTION

Use a vacuum pump to perform the vacuumizing process. Do not use refrigerant gas to discharge air. Use a vacuum pump that can vacuumize the pipe to the pressure of less than -100.7 kPa 5 Torr, -755 mmHg. When the pump is stopped, do not let the pump oil fow back into the refrigerant pipe. In order to prevent the entry of impurities, the R410A special tool must be used to ensure the compression strength. Use a flling hose with a top rod to connect to the maintenance access of the check valve or the refrigerant flling port.

Refrigerant Amount to be Added

Calculate the amount of the R410A refrigerant to be added based on the diameter and length of the liquid pipes of the ODU and IDUs.When the outdoor unit connects 1 indoor unit.

Additional refrigerant volume of divergent pipe is 0.1kg per item (Consider the liquid side of divergent pipe only.

The wire diameter and continuous length is under the condition that the voltage vibration is within 2%. If the continuous length is exceed showing value, choose the wire diameter follow relevant regulation.

Indoor unit power supply wiring

CAUTION

1. Refrigerant piping system, indoor unit-indoor unit connection signal wires and indoor unit-outdoor unit connection singal wire are in the same system.
2. hen power cord is parallel with signal wire, please put them into separate wire distribution pipes, and leave a proper distance.
3. Reference distance: It is 300mm when current capacity of power cord is less than 10A, or 500mm when 50A.
4. Please use shield wire as indoor unit/outdoor unit signal wire. Indoor/Outdoor unit signal wire wiring.

TEST RUNNING

Operate according to gist for test running on the electric control box cover.

CAUTION
Test running can not start until the outdoor unit has been connected to the power for 12hr. Test running can not start until all the valves are affirmed open. Never make the forced running. Or the protector sits back, danger will occur.

PRECAUTIONS ON REFRIGERANT LEAKAGE

This air conditioner(A/C) adopts inncouous and nonflammable refrigerant. The locating room of the A/C should big engough that any refrigerant leakage is unable to reach critical thickness. So certain esssential action can be taken on time. Critical thickness the Max. thickness of Freon without any harm to person. Refrigerant critical thickness: 0.44[kg/m ] for R410A.3  Confirm the critical thickness through follow steps, and take necessary actions.

• Calculate the sum of the charge volume (A[kg])
• Total Refrigerant volume of 10HP=factory refrigerant volume + superaddition
• Calculate the indoor cubage (B[m ]) (as the minimum3 cubage
• Calculate the refrigerant thickness.

Counter measure against over high thickness. Install mechanicalventilator to reduce the refrigerant thickness under critical leve ventilate regularly. Install leak alarm facility related to mechanical ventilator if you can not regularly ventilate.

Leak alarm related to mechanical ventilator.

NOTE
Please press constraint cool button to carry out refrigerant recycling process. Keep the low pressure above 0.2MPa, other wise compressor may be burnt out.
