  • Page 128 2. Guideline for each installation process • Use only copper wires. • Make sure to shut down the power before starting the electric wiring work. Do not set ON any switch until the work is completed. • The outdoor unit has an inverter compresser which generates noise and charges the outer casing with the leakag current. The outdoor unit should be grounded so that the effect of the generated noise on othe equipment can be reduced, and that the outer casing can be discharged.

Vacuum drying is : The use of a vacuum pump to vaporize(gasify) the moisture (liquid) inside the pipe and expel it leaving the pipes completely dry inside. At 1 atm(760mmHg) the boiling point (evaporating temperature) of water is 100°C but if a vacuum is created inside the pipes using a vacuum pump then the boiling point is rapidly reduced as the degree of the vacuum is increased.
  • Page 133 2. Guideline for each installation process 2.7.2 Evacuation ① Connect the manifold hose end described in the preceding steps to the vacuum pump to evacuate the tubing and indoor unit. Confirm the "Lo" knob of the manifold valve is open. Then, run the vacuum pump. The operation time for evacuation varies with tubing length and capacity of the pump.
  • Page 134 2. Guideline for each installation process 2.7.3 Choosing a vacuum pump The necessity for counter flow prevention After the vacuum process of the refrigerant cycle, the inside of the hose will be vacuumed after stopping the vacuum pump, the oil of vacuumpump may flow back. Moreover, if the vacuum pump stops during the operation for some reason. Therefore, in order to prevent the counter flow from the vacuum pump, a check valve is reguired.
  • Page 135 2. Guideline for each installation process 2) Vacuum pump maintenance Because of their nature, most vacuum pumps contain large amounts of oil which lubricates bearings, etc., and functions to enhance airtightness of pistons. When using a vacuum pump to discharge air from refrigerant piping, moisture in the air tends to get mixed in with the oil.

Guideline for each installation process 2.7.4 Vacuum drying procedure There are two vacuum drying methods and the appropriate one should always be chosen to confirm with individual local conditions. [Normal vacuum drying]..The standard method [Operational steps] ① Vacuum drying (1st time): Connect a manifold gauge to the service port of the liquid or gas pipe and operate the vacuum pump for at least 2 hours.
