Preliminary check

Check electrical power supply:

• Phase order: Reverse rotation is obvious if

the compressor do not build up pressure and
sound level is abnormal high. For DSH090-184
compressors equipped with internal reverse
vent valve which can protect compressor
without damage within duration below 24h. For
more details refer to section “Phase sequence
and reverse rotation protection”.

For DSH240 to DSH485 compressors equipped
with an electronic module, reverse rotation will
be automatically detected. For more details refer
to section "Motor protection".
• Voltage and voltage unbalance within tolerance:

For more details refer to section “Motor voltage”.

Initial start-up

System monitoring

• Surface sump heaters must be energized at least

6 hours in advance to remove refrigerant.

• A quicker start-up is possible by “jogging” the

compressor to evacuate refrigerant. Start the

compressor for 1 second, then wait for 1 to 2
minutes. After 3 or 4 jogs the compressor can
be started. This operation must be repeated for
each compressor individually.

The system must be monitored after initial
startup for a minimum of 60 minutes to ensure
proper operating characteristics such as:
• Correct superheat and subcooling.
• Current draw of individual compressors within

acceptable values (max operating current).

• No abnormal vibrations and noise.
• Correct oil level.

If Oil Top-up is needed, it must be done while the
compressor is idle. Use the schrader connector
or any other accessible connector on the
compressor suction line. Always use original
Danfoss POE oil 160SZ from new cans.
For more detailed information see “Lubricants
filling in instructions for Danfoss Commercial
Compressors” TI 2-025-0402.
