Electrical Power Supply; Spare Parts; Compressed Air System - KAESER SM 8 Service Manual

-
Do not allow open flame and flying sparks at the installation site.
-
Take necessary precaution when welding on or near the compressor package to en-
sure that sparks or high temperatures cannot cause fire or explosion.
-
Ensure that the compressor package is supplied only with clean uncontaminated air.
-
Do not allow the maximum ambient temperature to be exceeded (see chapter 1.6),
unless special measures have been agreed upon between the manufacturer and the
customer.
-
Perform oil changes according to the service manual or at least once annually (see
chapter 9.12).
-
Do not mix cooling oils of different types.
-
Maintain and monitor the operating temperature according to the manufacturer's
specifications to avoid build ---up of condensate or varnish in the oil circuit (see
chapter 1.1).

Compressed Air System

If a compressed air system is extended or changed, verify that the blowoff pressure and
capacities of the safety relief valves on the air receiver tanks and in the system match the
rating of all the compressor packages installed.
Safety
The main power supply and overcurrent protection must be installed
by a qualified electrician in accordance with NEC, OSHA and any appli-
