Important Safety Information 

Any hazard from reaction with other substances 

How to clean/dispose of spillage 

Appropriate protective measures 

Appropriate storage and handling 

Although these regulations may not be applicable in your country, it is strongly 
recommended that a similar approach be adopted for the protection of the students 
operating the equipment. Local regulations must also be considered. 

Water Borne Hazards 

The equipment described in this instruction manual involves the use of water, which 
under certain conditions can create a health hazard due to infection by harmful 
micro-organisms. 

For example, the microscopic bacterium called Legionella pneumophila will feed on 
any scale, rust, algae or sludge in water and will breed rapidly if the temperature of 
water is between 20 and 45°C. Any water containing this bacterium which is sprayed 
or splashed creating air-borne droplets can produce a form of pneumonia called 
Legionnaires Disease which is potentially fatal. 

Legionella is not the only harmful micro-organism which can infect water, but it 
serves as a useful example of the need for cleanliness. 

Under the COSHH regulations, the following precautions must be observed: 

 

Any water contained within the product must not be allowed to stagnate, ie. 
the water must be changed regularly. 

 

Any rust, sludge, scale or algae on which micro-organisms can feed must be 
removed regularly, i.e. the equipment must be cleaned regularly. 

 

Where practicable the water should be maintained at a temperature below 
20°C. If this is not practicable then the water should be disinfected if it is safe 
and appropriate to do so. Note that other hazards may exist in the handling of 
biocides used to disinfect the water. 

 

A scheme should be prepared for preventing or controlling the risk 
incorporating all of the actions listed above. 

Further details on preventing infection are contained in the publication “The Control 
of Legionellosis including Legionnaires Disease” - Health and Safety Series booklet 
HS (G) 70. 

Electrical Safety 

The equipment described in this Instruction Manual operates from a mains voltage 
electrical supply. It must be connected to a supply of the same frequency and voltage 
as marked on the equipment or the mains lead. If in doubt, consult a qualified 
electrician or contact Armfield. 

The equipment must not be operated with any of the panels removed. 

To give increased operator protection, the unit incorporates a Residual Current 
Device (RCD), alternatively called an Earth Leakage Circuit Breaker, as an integral
