6.4 EVAPORATOR WATER PIPE CONNECTIONS The water inlet and outlet must be connected in the positions indicated as labelled on the unit. If incorrectly connected the antifreeze thermostat will not operate and the evaporator may freeze. A constant water flow to the evaporator must be guaranteed at all operating conditions to prevent liquid refrigerant from entering the compressor and causing irreparable damage. Compressor operation is often intermittent, as cooling demands of the utility do not generally coincide with compressor delivery rates. On circuits with a low water content, where the effect of thermal inertia is less sensitive, the operator should check that each kW of cooling capacity corresponds to at least 5 litres of water in the hydraulic circuit. If the above values are not reached, a storage vessel should be installed, the capacity of which, when added to the circuit capacity, should ensure that the value specified above is reached. This storage vessel does not require special provisions, but should be efficiently insulated, as with all chilled water piping, to avoid the phenomena of condensation and a reduction in circuit output. It is mandatory to install a flow switch (supplied with the unit) on the evaporator water outlet connection identified by the following decal: It is compulsory to install a metallic filter, on the water inlet piping. If a filter is not installed the warranty will be terminated immediately. Air Blue • 13 EVAPORATOR WATER USER WATER
