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

NOTICE
!
!
Avoid a short-circuit of the air flow or obstacles
in the air flow of the condenser fans!

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 the case of a long suction gas line or sev-
eral evaporators, the use of the optionally available oil
separator and oil monitoring (OLC-K1) is urgently re-
commended.
When using an LHL5E with only one capacity-con-
trolled cylinder bank, the suction gas line must be de-
signed such that oil return is guaranteed at the min-
imum capacity of 50%. Oil level monitoring is recom-
mended.
If the ECOLITE condensing unit is positioned below the
evaporator, an additional subcooler should be provided
(example see figure 10, page 51).

A solenoid valve in the liquid line is urgently re-
commended!
