Use clean hoses. Make sure the inside is free of dust, residues,
water.
Avoid the entry of uncondensable gases (air) in the circuit,
otherwise, with the unit in operation, high pressures with the risk of
damages might ensue.

It is forbidden to use second-hand cooling lines since their flare
connection seal is not guaranteed.
