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.
Personal Refrigerant Leak Detector
Personal refrigerant leak detectors must be worn when servicing this machine.
Service Equipment
Use only manifold gauge sets designed for use with hydrocarbon refrigerants. Use only refrigerant recovery units and
cylinders designed for the pressure category of the refrigerants. Hydrocarbon refrigerant recovery machines must be used.
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.
The refrigerant must be stored in a clean, dry area away from sunlight. The refrigerant must never be stored above 50°C.
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.
Protective Personal Equipment
Airedale recommends that personal protective equipment is used whilst installing, maintaining and commissioning
equipment.
Care must be taken when working around the discharge pipe work of the unit. High surface temperatures may exist during
unit operation.
The refrigerant has a boiling point of -19°C.
Manual Handling
Some operations when servicing or maintaining the unit may require additional assistance with regard to manual handling.
This requirement is down to the discretion of the engineer.
Remember do not perform a lift that exceeds your ability.

Ecodesign Directive 2009/125/EC
The product range within this document is designed in accordance to the European Ecodesign Directive 2009/125/EC.
The appendix at the rear section of the manual gives the product compliancy metrics. Products sold outside of the EU
are exempt from this directive.
When working with any air conditioning units, 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.
Electrical installation commissioning and maintenance work on this equipment should be
undertaken by competent and trained personnel in accordance with local relevant standards and
codes of practice.
These Airedale chillers use 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 40°C.
All service personnel must have hydrocarbon refrigerant handling training.
