Safety
Note: Whenever a relief valve/safety valve has been activated, we recommend recalibrating it. This
must be carried out by competent personnel only. See also EN 378 and existing national legislation.
2.3.3 Water system
Warning!
The recirculation water system may contain chemicals or biological contaminants, including legionella,
which can be harmful if inhaled or ingested. Water systems should only be operated with an effective bi-
ological treatment programme.
2.3.4 Brine
In recent years alcohol, glycol and halogenated compounds have been used in the production of brine.
In general, all brines must be considered harmful to nature and they must be used with caution. Be very
careful when charging or purging a refrigeration plant.
Never empty brines down a sewer or into the environment.
The brine must be collected in suitable containers clearly marked with the contents and sent to an ap-
proved incineration plant.
2.3.5 Safety during maintenance and service
• Personnel must be competent according to national safety rules and regulations and perform
the maintenance work according to EN 378 and EN 13313/ISO 22712.
• Read chapter 2. Safety in this manual before opening the compressor and other parts of the re-
frigeration plant. If the switch is not locked, all start buttons must be tagged with “DO NOT
START” tags and an explanation: “Work on unit in progress”.
• Make sure that the motor cannot start up inadvertently. Switch off all electric components on the
compressor/unit before starting the dismantling/servicing process. It is recommended to remove
all main fuses.
• Make sure that there is no over-pressure and no refrigerant in the part to be dismantled. Close
all necessary stop valves.
• Use the prescribed tools, and check that they are properly maintained and in good working con-
dition. In explosion-proof areas, use tools suited for this specific purpose.
• Use only Johnson Controls Denmark original spare parts; other parts may impair the safety of
the compressor/unit.
• Use gloves and protective goggles, and make sure to have a gas mask close at hand.
2.3.6 Power supply
Danger!
• The voltage used in the drive can cause severe electric shock and/or burns and may be lethal.
Extreme care must be taken at all times when working with or close to the drive. Specific warn-
ings are given wherever relevant in this manual.
• The drive line is connected to voltage. Be aware of live circuits.
• Pay close attention to the electrical installation and system maintenance to avoid hazards both
during normal operation or in the event of equipment malfunctioning.
