Compressor storage
Each compressor is shipped with a nominal dry
nitrogen holding charge between 0.3bar (4 psi)
and 0.7bar (10psi) and is sealed with elastomer
plugs.
Respect the following sequence to avoid
discharge check valve gets stuck in open
position:
• Remove the suction plug first
• Remove the discharge plug afterwards
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 DSH scroll compressor is
equipped with two lift rings on the top shell.
• Always use both these rings 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.
• For tandem and trio assemblies, use a spreader
bar and all compressor rings as shown in picture
below.
• 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 not exposed to rain,
corrosive or flammable atmosphere between
-35°C (-31°F) and 70°C (158°F) when charged
with nitrogen and between -35°C (-31°F) and
Ts max value (see section "Pressure equipment
directive") when charged with R410A refrigerant.
