Health and Safety
IMPORTANT
The information contained in this manual is critical to the correct operation and maintenance of the unit and should be
read by all persons responsible for the installation, commissioning and maintenance of this Airedale unit.
Safety
The equipment has been designed and manufactured to meet international safety standards but, like any mechanical /
electrical equipment, care must be taken if you are to obtain the best results.
When working with any chillers ensure that the electrical isolator is switched off prior to servicing or repair work and
that there is no power to any part of the equipment. Also ensure that there are no other power feeds to the unit such as
fire alarm circuits, BMS circuits, crankcase heater permanent supplies etc.
Refrigerant Warning
These Airedale chillers use R134a or R1234ze (E) refrigerant which requires careful attention to proper storage and
handling procedures in accordance with EN 378. Maximum water temperature flowing through the chiller should be
42°C. All service personnel must have hydrocarbon refrigerant handling training.
Use only manifold gauge sets designed for use with refrigerants. Use only refrigerant recovery units and cylinders
designed for the pressure category of the refrigerants.
The refrigerant used in this range of products is classified under the COSHH regulations as an irritant, with set
Workplace Exposure Levels (WEL) for consideration if this plant is installed in confined or poorly ventilated areas.
A full hazard data sheet in accordance with COSHH regulations is available should this be required.
Refrigerants must only be charged in the liquid state.
The refrigerant must be stored in a clean, dry area away from sunlight. The refrigerant must never be stored above
50°C.
