Introduction

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 the 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.
CAUTION
1. Installation, service and maintenance of Airedale equipment should only be carried out by technically trained
competent personnel.
2. 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.
3. $OVRHQVXUHWKDWWKHUHDUHQRRWKHUSRZHUIHHGVWRWKHXQLWVXFKDV¿UHDODUPFLUFXLWV%06FLUFXLWVHWF4. 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.

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.
Refrigerant Warning
The Airedale SmartCool uses R410A refrigerant which is a high pressure refrigerant. It requires careful attention to
proper storage and handling procedures.
Use only manifold gauge sets designed for use with R410A refrigerant. Use only refrigerant recovery units and cylinders
designed for high pressure refrigerants.
R410A must only be charged in the liquid state.
The refrigerant must be stored in a clean, dry area away from sunlight and never be stored above 50°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.
Environmental Policy
It is our policy to:
Take a proactive approach to resolve environmental issues and ensure compliance with regulatory requirements.
Train personnel in sound environmental practices.
Pursue opportunities to conserve resources, prevent pollution and eliminate waste.
Manufacture products in a responsible manner with minimum impact on the environment.
Reduce our use of chemicals and minimise their release to the environment.
Measure, control and verify environmental performance through internal and external audits.
Continually improve our environmental performance.

The control panel contains the necessary compressor starter contactors, transformer, sub circuit protection, volt free
contacts for a common alarm and mains and inter-connecting terminals. The panel is situated within the cabinet and can
be opened to allow for essential maintenance of other components within the unit. The electrical control panels are wired
to the latest European standards and codes of practice.

The SmartCool range shall be designed with dual power supply capability, so that in the event of a power failure the
supply can be switched from utility to an alternative power supply (such as second utility or generator).
A dual power supply changeover switch shall be provided to enable continuous power to the SmartCool in order to
reduce unit downtime and therefore loss of cooling to a minimum.
For the dual power supply feature to operate effectively the two incoming power supplies must have the same voltage
and frequency.
During changeover of power there is an interval of ~180ms with no power. For critical applications a power backup
module can be added to maintain power to the unit controls, allowing for immediate reinstatement of cooling following
changeover.

Ultracap UPS
The ultracap module is an external backup device for the controller. The module guarantees temporary power to the
controller in the event of power failures and allows for enough time to keep the controller running with time to change
power supplies. The module is made using Ultracap storage capacitors (EDLC = Electric Double Layer Capacitor),
which are recharged independently by the module.
These ensure reliability in terms of much longer component life than a module made with lead batteries: the life of the
Ultracap module is at least 10 years.
Energy Manager
Analysis of system energy consumption can be monitored via a dedicated LCD display. Unit parameters can be adjusted
via the unit microprocessor control to affect energy usage in line with the system need.
Phase Rotation Protection
A phase sequence relay shall be available for units containing 3 phase scroll compressors, to prevent possible damage
by running the compressor in the wrong direction.

To modulate the rate of steam production, this system shall vary the level of water within the cylinder, thereby increasing
the immersion level of the electrodes and the current being passed between them. The more conducting area that is
available to pass current between the electrodes, the larger the amount of steam that shall be produced.
Modulated by the controller, the water level is varied so that the level of steam being produced ensures that the room
humidity set-point is continually maintained within a tight tolerance.

embedded in the software, determines the frequency that the bottle should be drained.
Example: (Optimised Lifetime with High Water Conductivity Supply)
As liquid water is boiled off into steam, mineral deposits are left in solution increasing the conductivity of the water.
To counter this, the intelligent software increases the frequency of drain meaning that the replenishing supply water
