Instructions
A refrigeration system component change must
be carried out in compliance with local regulations.
•
Make sure that the main power supply has been
switched off.
•
Before replacement, it is necessary to determine
the cause of failure and implement remedial ac-
tion. If such analysis and repair are not perfor-
med, repetitive failure may occur.
Note that an oil acidity test always proves help-
ful in diagnosis when undertaking compressor
replacement.
•
Check that the new Performer® compressor and
the on-site compressor to be replaced display the
same electrical and refrigeration performance
characteristics.
•
Use the rubber grommets and gaskets supplied
with the new compressor.
•
Whenever piping needs to be modified, please
refer to the "Safety measures prior to assembly"
section.
•
For further details on replacement steps, refer
to the previous sections of this manual.
• Danfoss recommends not to throw away a used
compressor but to dispose of the com-
pressor and its oil at a specialised recycling
company site.
Note: In the event of motor failure, flush and clean
the entire circuit before replacing the compressor
in order to remove acids and contaminants. Syste-

matically install a new filter dryer on the liquid line.
Prior to this step (if necessary), run the system for
at least 2 hours with anti-acid cartridges (in such
instances, the installation of a suction filter might
also be required). After an operating period of ap-
proximately 2 weeks, check the level of oil acidity.
If the oil acid test proves positive, drain and replace
the oil, replace the anti-acid liquid line filter dryer
cartridges and the suction filter previously installed.
Repeat oil and filter dryer replacements until the
system is clean and acid-free. When there is no lon-
ger any sign of acidity, replace the anti-acid cartrid-
ges by the standard model and remove the suction
strainer cartridge as required.

Insist that all service operations only be per-
formed by qualified personnel.
The compressor and tubing surface tempera-
tures may exceed 100°C (212°F) and cause severe
bodily burns. Special precaution must be taken
when working around the compressor and refri-
gerant tubing. Moreover, a compressor in opera-
tion can generate very cold surface temperatures
(as low as -25°C / -13°F), thereby exposing per-
sonnel to the risk of freezing burns.
Pressure inside the compressor can reach dan-
gerously high levels (e.g. abnormal operation,
fire,...) leading to personnel injury if suddenly
released; therefore, never drill, weld or cut the

compressor shell and adjacent tubing (release
of liquid refrigerant can cause flash freezing on
exposed skin).
Be aware that the product warranty may be
deemed null and void in the following cases:
•
external modifications to the compressor (ab-
sence of nameplate, drilling, welding, broken
feet, shock marks),
•
compressor opened by the user or returned un-
sealed (i.e. open discharge or suction ports),
•
presence of rust or water inside the compres-
sor
•
addition of leak-detection fluid in the lubricant
•
use of a refrigerant or lubricant not approved by
Danfoss Commercial Compressors,
•
any deviation from recommended instructions
pertaining to installation, application or mainte-
nance,
•
use in mobile applications (boats, trains, trucks,
etc.) or under explosive atmospheric conditions
(the compressor connecting box is not explo-
sionproof ).
The date of production of the compressor is indi-
cated on the nameplate. Ensure that the model
and serial number information is always transmit-
ted with any claim filed regarding this product.
