SAFETY PRECAUTIONS
This manual describes the safety precautions, structure and functions of all systems and
components, as well as the operation and maintenance methods for the KRSL series rotary screw
air compressors. The owner and operator shall read this manual carefully. Only after thorough
understanding should the machine be operated for the first time. This manual gives you a general
description of the mechanical and electrical systems and maintenance. However, if you have any
questions about operating and maintenance of the compressor; please contact your authorized
distributor or our service department personnel.
Do not modify the compressor and/or controls in any way except with written factory approval.
While not specifically applicable to all types of compressors with all types of main movers, most
of the precautionary statements contained herein are applicable to most compressors and the
concepts behind these statements are generally applicable to all compressors.
Failure to follow any of these precautions may results in severe personal injury,
death, property damage and/or compressor damage
1.3
PRESSURE
A properly sized pressure relief valve must be installed in the discharge piping ahead (upstream)
of any shutoff valve (block valve), heat exchanger, orifice or any potential blockage point.
Failure to install a pressure relief valve could result in the rupturing or explosion of some system
component. Relieve all pressure internally to the compressor prior to servicing. Do not depend
on check valves to hold system pressure. Do not change the pressure setting of the pressure relief
valve, restrict the function of the pressure relief valve, or replace the pressure relief valve with a
plug. Over pressurization of system or compressor components can occur, resulting in death,
severe personal injury or property damage. Do not operate the compressor at pressures in excess
of its rating. Never use plastic pipe, rubber hose, or soldered joints in any part of the compressed
air system. Failure to ensure system compatibility with compressor piping is dangerous.
1.4
FIRE AND EXPLOSION
Clean up any spills of lubricant or combustible liquid immediately. Keep sparks and flame away
from the compressor. Do not permit smoking during servicing, such as checking or adding fluid.
Wipe down spills immediately using industrial cleaner as required. Do not use flammable
material for cleaning purposes. Do not operate the compressor in a hazardous environment unless
