5.5 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.
CAUTION
High discharge pressure operation! Compressor damage!
Do not use
the 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 this requirement is met before start-up.
For brazing connections where dissimilar or ferric metals are joined a silver alloy rod with a
minimum content 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.
NOTE:
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.
5.6 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.
5.7 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.
