Proper use:
REFCO products have been developed and manufactured specifically for use by trained
refrigeration engineers and technicians. Due to the high pressure levels as well as the
chemical and physical gases used in refrigeration systems, REFCO accepts no responsibility
or liability in the event of accidents, injuries or death.
The pressure regulator has been developed especially for pressure regulation of nitrogen
(N2). The maximum primary pressure is 220 bar. The secondary pressure is 5 - 50 bar. The
safety valve (pressure relief valve) is set to 55 bar. Interference with the safety valve is
forbidden.
The pressure regulator may only be used for nitrogen pressure cylinders. This set should
only be used for testing refrigeration systems using nitrogen.
Improper use:
• Do not use the pressure regulator for gases in the liquid phase.
• Do not operate the pressure regulator in ambient temperatures below
-30°C and over +60°C.
• Do not use the pressure regulator for aggressive gases, e.g. ethylamine,
dimethylamine, ammonia, etc.
• The device may not be used for purposes other than those relating to
air conditioning and refrigeration.
