has been in service for a reasonable period of time you
can perform a check on the operating and safety
devices. The settings are shown in Tables II and III.
All servicing of the equipment is to be considered
extraordinary maintenance and may be carried out BY

may cause serious damage to the unit and injuries to
persons.
The operating parameters and control system settings
configurable by means of the microprocessor control are
