•
Suction pipework should slope gently back towards the
unit to assist oil return to the compressor. A fall of
approximately 2cm per meter of pipework is
acceptable.
•
The maximum recommended pipe length is 50m.
•
Additional oil may be required if piping length
exceeds 20m or multiple oil traps are fitted. Check the
oil level closely during commissioning and add oil, as
necessary. Add oil in small amounts.
Do not overfill
the compressor!
•
It is recommended to install Pressure Relief Valve on
the liquid receiver if there is a risk of fire incidence.
Increasing temperature will lead to pressure increase in
receiver.
•
No valves and detachable joints shall be in areas
accessible to the public except when they comply with
EN 16084.

One of the main factors affecting equipment
reliability and compressor service life is
refrigeration circuit contamination.
During installation, circuit contamination could cause by:
•
Brazing and Welding Oxides
•
Filings and Particles from de-burring pipework
•
Brazing Flux
•
Moisture & Air
Pipe Sizing
When refer
Table 6
for selecting the connecting pipe size, the total equivalent length must include elbows and other components
that would increase the equivalent length.
Table 6: Total Equivalent Length
Notes:
(1)
The pipe sizes indicated in bold are from condensing unit to ‘T’ piece.
(2)
The pipe sizes indicated in brackets
are from ‘T’ piece to each evaporator.
(3)
Pipework should be selected on the total equivalent length of run between units.
(4)
For pipe sizing on runs longer than 30m, please contact J & E Hall.
