This unit is designed to be safe in the use for which it was planned, provided that it is installed, started
up and maintained in accordance with the instructions contained in this manual.
The unit contains electrical components that operate at line voltage and contains moving parts. It must
be isolated from the electrical supply before being worked on. All maintenance operations that require
access to the unit must be carried out by suitably qualified technicians who have a thorough
understanding of all necessary precautions associated with refrigeration and electrical machinery. The
unit is not to be used by the infirmed or children unless they are supervised by responsible persons
qualified to carry out the supervision. All panels must be re-installed after carrying out any
maintenance work. The unit should be secured to prevent it from toppling over.
Minimum temperature setting is 5°C on the unit. Any lower than this may cause problems with the
evaporator icing up and potentially loss of refrigerant and potentially expensive service costs
The liquids to be cooled must be compatible with the materials used in the constructions of this unit.
These liquids can be water or mixtures of glycol and water for example. The liquids to be cooled must
not be flammable.
WARNING
All wiring must be performed by qualified electricians. Improperly installed wiring
and grounding may result in electrocution and fire hazards. To avoid these hazards
all wiring must be installed in accordance with all the local relevant safety standards
for wiring.
WARNING
The chiller contains refrigerants under high pressure. The system also contains oils
under high pressure. Before the refrigeration circuit can be opened, the refrigerant
should be reclaimed to reduce pressure in the system. Failure to recover the
refrigerant to relieve pressure or the use of refrigerants or refrigerant substitutes that
are not specified for the unit may result in system rupture and explosion.
Refrigerants have a narcotic effect when inhaled in high quantities. Should a leak occur of the
refrigerants then the room should be vacated and should only be re-entered after suitable ventilation.
