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 control panel is fitted with a

stop device as shown below. When operated, it

removes the 115 Vac supply to the control system. A

remote emergency stop device may also be connected

to the control system.

1.8 Safety Labels

The following labels are fixed to each unit to give

instruction, or to indicate potential hazards which may

exist.
