Refrigerant Line Installation notes
Refrigeration lines manufactured should conform to the following
norms.
Coil inlet line diameter 9.5mm – 3/8” to 15mm – 5/8”
Maximum recommended length 5m (15ft)
Coil outlet line diameter 15mm – 5/8” to 19mm – ¾ “
Maximum recommended length 5m (15ft)
Minimum insulation 60mm of closed cell “Armaflex™”
Note:
To maximise system performance, the
refrigeration lines should be as short as
possible
Note:
Do Not
repeatedly bend the refrigerant line
as this will cause leakage and or breakdown of the
insulation materials
Note:
It is vital that a new o-ring is used every time
a connection is made or broken. Always use the o-
ring removal tool when removing an “O-Ring”.
Take care not to damage mating surfaces of the
connections.
