6.3 Pipelines
The pipelines must be as short as possible in order to
minimise pressure drops and to keep the refrigerant
quantity available in the pipeline system as low as pos-
sible.
NOTICE
During soldering work on the suction gas line,
protect the low pressure transmitter against ex-
cess heat (max. 120°C)!
6.4 Incorporation of the condensing unit into the
refrigeration system
If the ECOLITE condensing unit is positioned above the
evaporator, the suction gas line must be executed ac-
cordingly. In case of a long suction gas line or several
evaporators, the use of the optionally available oil sep-
arator and OLC is recommended.
When using an LHL5E with only one capacity-con-
trolled cylinder bank, the suction gas line must be ex-
ecuted such that the oil return is guaranteed even at a
minimum capacity of 50%.
If the ECOLITE condensing unit is positioned below the
evaporator, an additional subcooler should be provided
(example see figure 9, page 11).
