Initial Start-up
CAUTION
Oil dilution! Bearing malfunction! It is important to ensure that new compressors are not subjected to liquid abuse. Turn
the crankcase heater on 12 hours before starting the compressor.
High discharge pressure operation! Compressor damage! Do not use compressor to test opening set point of
high-pressure cut-out.
•
The compressor must be equipped according to our technical documentation considering the application intended. Make sure of
this before start-up.
•
For brazing connections where dissimilar or ferric metals are joined, a silver alloy rod with a minimum of 30% silver shall be used
being either flux coated or with a separate flux.
•
Bolt torque settings are listed in Appendix 2.
•
With the exception of rubber-coated metallic gaskets (Wolverine) all gaskets should be oiled before fitting. O-rings should also be
oiled.
A compressor should never be operated beyond its approved application range! Check by consulting the appropriate data sheet.
To avoid motor damage the compressor MUST NOT be started, nor may high-potential testing be carried out under vacuum.
Minimum Run Time
Emerson Climate Technologies recommends a maximum of 10 starts per hour. The most critical consideration is the minimum run time
required to return oil to the compressor after start-up.
Recommended Inverter Range
Stream compressors are released for inverter applications from Control Techniques or other brands available on the market. Over a
frequency range, the compressor system combination can have frequency bands with higher vibration. The degree of vibration and
frequency bands are highly dependent on the system. To help reduce these vibration levels, rubber mounting should be used on all
inverter driven compressors.
Active oil management should be used for all inverter driven compressors.
