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.
