Handling
Compressor storage
Each compressor is shipped with a nominal dry
nitrogen holding charge between 0.3 and 0.7 bar
(4 psi and 10 psi) and is sealed with elastomer
plugs.
Respect the following sequence:
•
Remove the nitrogen holding charge via the
suction Schrader valve to avoid an oil mist blow
out.
•
Remove the suction plug first and the discharge
plug afterwards to avoid discharge check valve
gets stuck in open position.
An opened compressor must not be exposed to
air for more than 20 minutes to avoid moisture is
captured by the POE oil.
Each Danfoss VLZ scroll compressor is
equipped with one lift ring on the top shell.
• Always use one lift ring and discharge tube
when lifting the compressor.
• Use lifting equipment rated and certified for
the weight of the compressor or compressor
assembly.
• A spreader bar rated for the weight of the
compressor is highly recommended to ensure a
better load distribution.
• The use of lifting hooks closed with a clasp is
recommended.
• Never use the lift rings on the compressor to lift
the full unit.
Maintain the compressor in an upright position
during all handling manoeuvres (maximum of
15° from vertical).
- Store the compressor where is not exposed to
rain, corrosive or flammable atmosphere.
- Store the compressor between
-35°C and 70°C (-31°F and 158°F) when it is
charged with nitrogen.
- Store the compressor between -35°C and
55°C (-31°F and 131°F) when it is charged with
refrigerant.
