SAFETY FIRST
Warning, Safety First!
The air conditioning system described in this manual has the following
areas, which may be dangerous if not treated with great care.
Wear correct personal protective equipment when cleaning and
servicing this unit due to hazardous fibres which may be caught by all
stages of filtration during regular unit operation.
The electrical power system is supplied by 12v dc or 24v dc. no work
should be carried out on the system without the correct electrical safety
measures being taken and all relevant circuit breakers opened to isolate
the circuit.
The air conditioning system has various types of rotating equipment
installed. Ensure all safety guards are in place while the system is
running.
The refrigeration system, components, and copper pipework used in
the air conditioning unit are under high pressure and can cause serious
injury if the system is opened without following correct procedures.
The refrigeration system, components, and copper pipework contain
liquid or vapour mixtures under pressure, which can freeze and cold-
burn human body tissue resulting in permanent damage if the system is
opened without following the correct procedures. This damage can
occur within one second when running; the equipment has several hot
(>60⁰) and cold (>-5⁰) areas.
While servicing the equipment, be well aware of these areas to avoid
injury.
