◇
Paint a thin layer of frozen oil at both inside and outside part of the expanding.
◇
Make the expanding right to the screw thread shape connection of the indoor unit, using
hands to tighten the nut then using a wrench to tighten the nut again, the tighten torque as
follows figure.
7.6 Equivalent pipe length conversion
Equivalent pipe length means converting pipe elbow to straight pipe length after
considerate the pressure loss.
Elbow and Oil loop conversion tablet
Type Pipe Dia.(mm) Bend Oil Loop
6.35 0.10 0.7
9.52 0.18 1.3
12.70 0.20 1.5
15.88 0.25 2.0
19.05 0.35 2.4

Equivalent pipe length L
＝
ActualPipe length L+ Bend Qty× Equivalent pipe bend
Oil Loop Qty × Equivalent Oil Loop length
Sample:
ALCA-H24/NDR3HAA Actual Pipe length is 20 meters, Gas pipe diameter is 15.88mm. If
there’s 4 bends and 2 oil loops during the installation, then the equivalent pipe length
should be:
L=20+0.25×4+2×2=25(m)
