SECTION 1 – GENERAL INFORMATION AND SAFETY

Heat Radiation

Some of the visible parts like discharge pipe and driver heat

sink 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.

Use of gloves and safety glasses is, however, recomm-ended

when working on the unit. The buildup of refrigerant vapor,

from a leak for example, does pose a risk of asphyxiation in

confined or enclosed spaces and attention should be given to

good ventilation.

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.

Emergency Shutdown

In case of emergency, the HMI panel or the control panel is

fitted with a Unit Switch to stop the unit in an emergency. When

operated, it removes the low voltage 230 VAC electrical supply

of the control panel, thus shutting down the unit.

Safety Labels

The following labels are fixed to each unit to give instruction,

or to indicate potential hazards which may exist.
