Installation
WARNING! The laying of the lines and the
refrigerant connections must be carried out by
a qualified refrigerant circuit technician.
the refrigeration circuit must be connected to the condensing
unit with copper pipes. the diameter of the pipes must be
chosen according to the length of the refrigerant line itself
(preferably less than 30 m) therefore it is possible that the
internal diameter of the valves supplied by trAne will not
coincide with the diameter of the pipes.
Conforming to the Standards en 14276-1 and en 14276-2
the minimum recommended thickness for the gas supply
pipe where bends are made for the air cooled units with
r410A refrigerant, must be equal to the values present in the
attached table below. the value `r’ refers to the minimum
allowed radius of the bend.

During the installation of the cooling unit, a solenoid
valve should be fitted on the liquid line between the inner
unit and the external condenser, to avoid malfunctioning
and to protect the compressor from unwanted liquid
migration during start- up.

to connect the refrigerating circuit to the condensing unit
proceed as follows:
•
check that the diameter of the connections corresponds
to the diameter of the pipes to be connected. if
necessary use suitable copper reductions;
•
weld the piping coming from the condensing unit to the
connections of the air conditioner respecting the inlet
and outlet directions of the refrigerant.
note: with external temperatures of less than -10°C the
use of condensers for low temperatures is recommended:
cap Lt optional.
