GAS line:
gas precharge (pipe Ø 1/2")

LIqUID line (above to 2m):
55 g/m (pipe Ø 3/8")
For refrigerant lines with a length between 25 and 45m (to be mounted on the site) the diameters, the refrigerant
charge and the installation safety measures must be determined professionally.

PIPES TO BE MADE ON SITE
Condenseur at the same level as the
indoor unit
L. max = 45m
L
minimum slope
1cm/m downwards
This operation should be performed expertly by qualified
professionals (refrigeration engineer) (brazing, vacuum,
charge, etc ...).
Unroll the pipes carefully, in the opposite direction to the
spirals, to avoid bending them.
REFRIGERATION PIPE BENDING
The bending radius of the pipes should be equal to or more than 3,5 times de outside
diameter of the pipe.
Do not bend the pipes consecutively more than three times and do not make more than
12 bends over the complete length of the link.
