SECTION 1 - GENERAL CHILLER INFORMATION AND SAFETY

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 glass-
es is, however, recommended 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.
Use only the refrigerant specifically designated for the
unit. Any other type of refrigerant may cause damage
to the equipment and will void the warranty.

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 control panel is fitted with
an incoming supply circuit breaker with a red and yel-
low handle which can be used as the emergency stop
device. When operated it removes the electrical supply
to the inverter, fans, and control circuit thus shutting
down the unit.
