Refrigerant Piping Connection - Beko BIHPR 090 User Manual

5 Refrigerant piping connection

When connecting refrigerant piping, do not let
substances or gases other than the specified
refrigerant enter the unit. The presence of other
gases or substances will lower the unit's capacity,
and can cause abnormally high pressure in the
refrigeration cycle. This can cause explosion and
injury.
The length of refrigerant piping
will affect the performance
and energy efficiency of the
unit. Nominal efficiency is
tested on units with a pipe
length of 5 meters (16.5ft)( In
C North America, the standard
pipe length is 7.5m (25').
A minimum pipe run of 3
metres is required to minimise
vibration & excessive noise.
In special tropical area, for
the R290 refrigerant models,
no refrigerant can be added
and the maximum length of
refrigerant pipe should not
exceed 10 meters(32.8ft).
Refer to the table below for specifications on the
maximum length and drop height of piping.
