1 Did oil pressure come up immediately?
2 Are there any strange noises or shaking in
the compressor?
3 Are there any oil leaks?
4 Have all safety/fault functions been tested?
5 If the compressor driver (prime mover) is an
electric motor, check the current draw with the
compressor under full load.
3.5.5 Maximum
Allowable
Working
Pressure
The Maximum Allowable Working Pressure is defined as the maximum
continuous pressure for which the manufacturer has designed the equipment (or
any part to which the term is referred), when handling the specified fluid at the
specified temperature.
All Rhino Compressors Cylinders have a Maximum Allowable Working
Pressure (MAWP), this and the hydrostatic test pressure and test date are
stamped on the end of every cylinder. Any relief valves will be set to operate at
not more than the maximum allowable working pressures but not less than the
values listed below.

Table 7 The Maximum Allowable Working Pressure
* For related discharge pressures above 5000 psig (345 bar), the relief valve setting shall be
agreed upon between the purchaser and Intermech Limited.
Rated Discharge Pressure is defined as the highest pressure required to meet the
conditions the purchaser specifies for the intended service. Maximum allowable
working pressure shall exceed the rated discharge pressure by at least 10 percent
or 25psi (1.7 bar), whichever is greater.
