The unit is not designed to withstand loads or stresses from adjacent equipment, pipework or
structures. Additional components must not be mounted on the unit. Any such extraneous loads may
cause structural failure and may result in injury to the operator, or damage to the equipment.
General Access
There are a number of areas and features, which may be a hazard and potentially cause injury when
working on the unit unless suitable safety precautions are taken. It is important to ensure access to
the unit is restricted to suitably qualified persons who are familiar with the potential hazards and
precautions necessary for safe operation and maintenance of equipment containing high
temperatures, pressures and voltages.
Pressure Systems
The unit contains refrigerant vapor and liquid under pressure, release of which can be a danger and
cause injury. The user should ensure that care is taken during installation, operation and maintenance
to avoid dam- age to the pressure system. No attempt should be made to gain access to the
component parts of the pressure system other than by suitably trained and qualified personnel.
Electrical
The unit must be grounded. No installation or maintenance work should be attempted on the electrical
equipment without first switching power OFF, isolating and locking-off the power supply. Servicing
and maintenance on live equipment must only be performed by suitably trained and qualified
personnel. No attempt should be made to gain access to the control panel or electrical enclosures
during normal operation of the unit.
Heat Radiation
Some of the visible parts like discharge pipe may work under high temperatures, thus radiate high
heat flux. Special attention must be paid while getting close to the unit. Touching is prohibited during
normal operation.
Rotating Parts
Fan guards must be fitted at all times and not removed unless the power supply has been isolated.
Sharp Edges
The fins on the air-cooled condenser coils have sharp metal edges. Reasonable care should be taken
when working in contact with the coils to avoid the risk of minor abrasions and lacerations. The use
of gloves is recommended.
Frame rails, panels, and other components may also have sharp edges. Reasonable care should be
taken when working in contact with any components to avoid risk of minor abrasions and lacerations.
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. They are pre-charged before delivery to customer and normally
dispense with the need of additional charging, unless the machine is not working properly.
