Warnings - Uniflair Aquaflair 00182 Instruction Manual

This unit has been subjected to risk analysis under EC Directive 98/37/CEE (89/392/CEE). The technical
solutions implemented during the design phase are described in the unit's technical file.
This equipment is manufactured to function safely for the purposes for which it was designed as long as the
installation, operation and maintenance are carried out according to the instructions in this manual
and on the labels attached to the unit.
Warnings in this manual which are particularly important for user safety are shown by this danger symbol.
IMPORTANT WARNINGS
This unit contains refrigerant gas circuits, chilled water under pressure, live electrical components, hot
surfaces, sharp edges (the fins on the coils) and rotating devices such as the fans.
All service and maintenance operations which require access to the inside of the unit while it is in
operation must be performed by qualified and experienced personnel who are aware of the necessary
precautions.
Before accessing the inside of the unit, disconnect it from the electrical power supply.
In any case, all safety legislation of the installation location must be followed.
In the event of fire water and other conductive substances must not be used to put out the fire near live
electrical components. This warning must be displayed on notices in the unit installation location.
If the refrigerants used come into contact with fire they decompose, forming acids and other irritants. The
smell of these substances, even at concentrations below danger levels, gives enough warning to allow
evacuation of the area at risk.
Make sure that the mains supply to the unit is the same as that shown on the rating plate.
Drain all water from the system before the winter season to avoid freezing.
In periods in which the temperature may fall below 0°C, empty the unit in order to prevent the serious damage
caused by the formation of ice.
This precaution is not necessary if the unit is charged with an appropriate anti-freeze mixture.
Free cooling chillers must be loaded with anti-freeze.
If the unit is fitted with the optional heating cable, it must be turned off without cutting the electrical power
supply.
Install a mechanical filter in the section of tubing near the intake of the unit to prevent the fouling of the
heat exchanger with pieces of welding or flakes of oxidised metal from the water mains.
