Electrical
The unit must be earthed. No installation or
maintenance work should be attempted on electrical
equipment without first switching off, isolating and
locking-off the power supplies. Work on live equipment
must only be carried-out by suitably trained and
qualified personnel. No attempt should be made to gain
access to inside of the control panel, wiring or other
electrical enclosures during normal operation of the unit.
Refrigerants and Oils
Refrigerants and oils used in the unit are generally
non-toxic, non-flammable and non-corrosive, and pose
no special safety hazards. Use of gloves and safety
glasses are, however, recommended when working on
the unit. Build up of refrigerant vapour, from a leak for
example, does pose a risk of asphyxiation in confined or
enclosed spaces and attention should be given to good
ventilation. For more comprehensive information on
safety precautions for use of refrigerants and oils, refer
to the Materials Safety Data tables provided.
High Temperature and Pressure Cleaning
High temperature and pressure cleaning methods (e.g.
steam cleaning) should not be used on any part of the
pressure system as this may cause operation of the
pressure relief device(s). Detergents and solvents
which may cause corrosion should also be avoided.
1.7
Emergency Shutdown
In case of emergency the unit can be shut down by
operating the main power switch on the control panel.
1.8
