compressor to decide to add the oil after minimum 2
hours operation.
• It is recommended as well to install the MOP (Maximum
Operation Pressure), expansion valve for medium
evaporating temperature units, if the working suction
pressure during start procedure especially after defrost
cycle, is out of the limit, as refer to the table provided.
Recommend compressor working pressure range
3.5 Pressure testing
• Make sure that both service valves are closed when
running a pressure test on field piping, always use an
inert, dry gas such as Nitrogen
• The pressure differential between the high and low side
shall not higher than below.

(435 psig)
• Test pressures shall be as shown follows.
Test pressure

Low side
28 barg
(405 psig)
19 barg
(275 psig)
• If there is pressure drop, check the leakage portion.
3.6 Leak detection
• Make sure that all manual valves are open
• Perform a leak test of the system using nitrogen mixed
with the refrigerant to be used
• Do not use CFC for leak testing the condensing unit
which will be used with HFC refrigerants
• The use of leak testing fluids is not recommended as
this may interact with the lubricants own additives
3.7 Vacuum - moisture removal
Air and moisture reduce service life and increase
condensing pressure causing abnormally high discharge
temperatures likely to destroy the oil’s lubricating properties.
The risk of acid formation is also increased by air and
moisture and copper plating can be generated in this way.
All these phenomena can cause mechanical and electrical
failure.
3.8 Safety pressure switch settings
The pressure switch fitted to condensing units with auto
reset for low pressure and manual reset for high pressure
are NOT
factory preset.

High pressure safety (Manual reset)
The high pressure safety switch is required to protect the
compressor from working out of its envelope. The high
pressure switch shall set equal or lower than below values
depending on the type of refrigerant, application and the
ambient condition.

Important Note
Ensure that a good quality vacuum pump is used to pull
a minimum vacuum of -0.1 barg (250 microns) or less.
Ensure that no pressure increase during 1 hour or more
after stop vacuuming. If pressure increase, there is
moisture or leakage along the pipeline.
Important Note
Moisture prevents proper functioning of the compressor
and the refrigeration system
