Refrigerant Piping Connection - Beko BEHPH 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 North
C
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.
