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.
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.
A full hazard data sheet in accordance with COSHH regulations is available should this be required.
Personal Protective Equipment
Airedale recommends that personal protective equipment is used whilst installing, maintaining and commissioning
equipment.
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.
Refrigerant Warning
The product range within this docment utilises
R32
refrigerant which requires careful attention to proper storage and
handling procedures. Use only manifold gauge sets designed for use with
R32
refrigerant. Use only refrigerant recovery
units and cylinders designed for use with A2L refrigerants. The refrigerant must be stored in a clean, dry area away from
sunlight. The refrigerant must never be stored above 50°C.
Pressure Equipment Directive (2014/68/EU)
Minimum and Maximum Operation Temperature (TS) and Pressure (PS)
Refrigeration
AllowableTemperature Range (TS), = Min -20°C* to Max 135°C
**
Maximum Allowable Pressure (PS), = High Side
40.2 Barg Low side 29 Barg
*Based on the refrigerant temperature in the unit off state in the lowest permitted ambient temperature.
**Based on the maximum allowable super heated refrigerant temperature.
Waterside
AllowableTemperature Range (TS), = Min -20°C* to Max 40°C**
Maximum Allowable Pressure (PS), =
10 Barg
*Based on the waterside temperature in the unit off state in the lowest permitted ambient temperature.
**Based on the waterside temperature in the unit off state in the highest permitted ambient temperature.
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 fi re alarm circuits, BMS circuits
etc.
CAUTION
The waterside temperature should not go above the TS of +40°C. The PRV will release at water temperatures >=
46.7°C.
Pressure System Safety Regulations 2000
Refrigeration assemblies/systems may constitute a Pressure System as defi ned in the Pressure System Safety
Regulations 2000.
Global Warming Potential
The
R32 refrigerant has a GWP of
675 (based on EN378-1:2016, 100 year life)
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.
