39 39 Copyright Riello S.p.A. - Confidential AIR HP Edit by: Marketing Riello Export Controls – Internal safeties Several routines are built-in in the PCBs so to grant at any time the best working conditions of all the components and to protect both the machine and the installation while maximising the comfort for the user. -MAIN and ADDITIONAL pump anti-seizing function -Room anti-freeze function -Compressor Short Cycling Protection (Timeguard): to protect the compressor form short cycles and too often on/off. The maximum allowed number of cycles every hour is SIX -Minimum Compressor Run Time: to protect the compressor form short cycles and too often on/off. The compressor is forced to work for a minimum of three minutes even if in the meantime the heat request has stopped -Water anti-freeze protection: should the water in/out the plate heat exchanger go below a certain value, the compressor is stopped -Water over-temperature protection: should the water in/out the plate heat exchanger go over a certain value, the compressor is stopped -Water anti-frost protection due to outdoor temperature. The trace heater, the water pump, the machine are turned ON in sequence according to the probes readings. -Discharge temp release control: compressor protection due to over-temperature of the refrigerant temperature reading. -Current release control: compressor protection due to over-current absorbed

40 40 Copyright Riello S.p.A. - Confidential AIR HP Edit by: Marketing Riello Export Controls – Comfort functions. -In all the machines the fans speeds are modulated so to reduce the noise: 4;6;8 kW machines – modulation along a continuous range of values; 12;15 kW units: the two fans are modulated with different speeds - compressor warm up procedure: it warms up the compressor to avoid a slackness of refrigerant inside the component. The procedure is monitored and stopped reading the current absorption - defrost control on the fanned heat exchanger, so to grant constantly the efficiency of such exchanger.

WEEE (2003/108/EC) Units must be collected separately after its use is completed, and cannot be disposed as unsorted municipal waste. Objectives: to tackle the fast increasing waste stream of electrical and electronic equipment, to increase recycling of electric & electronic equipment (EEE), to limit the total quantity of waste EEE (WEEE) going to final disposal. The crossed out wheeled bin symbol that is affixed to the product means that this product falls under the Directive. The user is responsible for returning the product to the appropriate collection facility, as specified by your municipality or the distributor. In case of installation of a new product, it may be possible to have the distributor pick up old WEEE directly.

45 45 Copyright Riello S.p.A. - Confidential AIR HP Edit by: Marketing Riello Export In the following slides there are a few installation schemes with the purpose to give a flavour of the different possible installations of the machine inside a (new or renovated) system. It is important to notice that there is the need for the installer to complete the system with a handful of components, among which the most important is probably the WATER FILTER. It is in fact extremely important to avoid that any dirt, metal shavings, sludge, dirt end up in the plate heat exchanger, to avoid its seizing. Schemes examples
