order to avoid the excursion, the angle between the ropes should be less than 40 degree.
Please use M12 to tight the support fundus.
3) Refrigerant pipe connection
Note:Do not loosen the cap of the pipes when connecting the pipes between the indoor unit and the
outdoor unit. Connecting the pipes as soon as possible after loosening the cap of the pipes to avoid the
entering of water and dusk. A metal pipe should be utilized if a pipe should be installed through a wall.
◆ The connection of the pipes should confirm to the following principles:
◆ Make sure to lessen the length of connecting pipe, the height difference between the indoor and
outdoor unit, and the number of bends, and enlarge the diameter of bends.
The permitted maximum value of each case:
Height difference between the indoor and outdoor unit
＜ 30m
90° Number of bends
＜ 12
Length of connecting pipes
＜ 50m
◆ The pipe meld type could be employed for the connection of the pipes between the indoor and
outdoor units.
◆ The pipe joint should be tightly connected when a pipe joint is employed between two pipes. It
is better to use only one connecting pipe if the distance is not far.
◆ The pipes should not be shriveled when the pipes are connecting. The bend diameter should be
longer than 200 millimeter. The connecting pipes should not be extended or curved frequently and the
curving process should not be larger than 3 times in the same bending position.
4) Vacuum evacuating, leakage testing and refrigerant charging
◆ The system is charged with nitrogen gas from the low-pressure valve until the pipe pressure
increasing to 1Mpa, and the leakage is examined at the connecting or welding position with soap water.
33
The air is evacuated in the pipe from the check valve with a vacuum pump if no leakage exists, then
loosens the cores of the liquid valve and gas valve and clears the soap water with dry cloth.
◆ If the vacuum pumps and high-pressure nitrogen are not available, we can operate as following:
Remove the cores of the liquid valve and gas valve and loosen the cores of check valve on the gas
valve and the gas will exhaust. Keep exhausting for 15 seconds, tightening the check valve as refrigerant
gas coming out.
Loosen the liquid valve and gas valve.
Tighten the bonnet of the valve, and examine the air leakage at the connecting position with soap
water or gas leakage detector, then clear the soap water with dry cloth.
◆ Wrap the flare nut with insulation material to avoid the condensation dropping after finishing
the preceding procedure.
The refrigerant in the conditioner unit is enough for the connecting pipes of 7.5 meters, if the pipe
is longer than 7.5 meters, additional supplement refrigerant should be supplied. The maximum pipe
length is 50 meters. When the height difference between the indoor unit and outdoor unit is larger than
10 meters, an oil bend should be employed for every 6 meters.
