Pipelines; Incorporation Of The Condensing Unit Into The Refrigeration System - Bitzer LHL3E/2EES-2Y Instructions De Service

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).
