Installing the air conditioner
Refrigerant pipe work
Insulating the pipes
f Make sure to insulated the refrigerant pipes with an insulation tape. If the
f
pipe is not insulated, condensate may form and drop into the indoor.
f Wind the refrigerant pipes and the drain hose with vinyl tapes.
f
f When you bend the pipe, try to secure large bending radius (over 100 mm)
f
to prevent the copper pipe from distorting.
f Use foamed polyethylene or EPDM foam, with thickness over 7 mm, as an
f
insulator.
f If the pipe is installed in a place with humidity over 80 % (such as within a
f
pit of a building, basement, sea shore, near hot spring or lake etc), use an
insulator with a thickness over 10 mm.
f Insulate the high pressure (liquid pipe)/low pressure (gas pipe) pipe, and finish it by winding up the vinyl tape around it.
f
f Make sure to insulate the pipe with no gap or cracks, and use adhesive between the connection part of the insulator to
f
prevent moisture from entering.
f Make sure that the thickness of the insulator doesn't get thinner on the bending part of the pipes.
f
f Use extra insulator to secure thickness when the insulator becomes thinner.
f
f When the pipe hanger is installed, wind the extra PE Foam type insulator (over 5 mm) with the width 3 times wider than
f
the hanger. (Do not use cable tie as an hanger.)
Oil trap
Check the following list and install an oil trap.
f Install an oil trap only when the outdoor unit is at a higher level than the indoor unit.
f
f Based on cooling operation, install it on the gas side pipe only.
f
f Install the oil trap only in between the outdoor unit and the first branch joint and it should be installed at every 10 m.
f
f Radius of curvature (R) on the oil trap are as follows:
f
Pipe diameter (D)
12.70
15.88
19.05
22.23
25.40
28.60
31.75
f Height of the oil trap (H): 4R ≤ H ≤ 6R
