1 - INTRODUCTION AND SAFETY INSTRUCTIONS The units are designed to heat water (heating mode) and cool water (cooling mode) for the air conditioning / heating of buildings and industrial processes. They are designed to provide a very high level of safety and reliability, making installation, start-up, operation and maintenance easier and safer. They will provide safe and reliable service if used within their application ranges. For all safety instructions, please refer to the safety manual.
3 - HANDLING AND POSITIONING 3.1 - Handling 3.2 - Positioning CIAT strongly recommends employing a specialised company The machine must be installed in a place that is not accessible to unload the machine. to the public and is protected against access by non-authorised persons.

NOTE: If the walls are higher than 2 m, contact the factory. 3.2.2 - Positioning of potentially flammable zones The full unit, including all options & accessories that are delivered by CIAT, has been qualified for the use with R290 refrigerant. For that purpose, CIAT is compliant with EN 378-2 §6.2.14 and has defined potentially flammable zone using EN 60079-10-1 in order to identify where ignition sources must not be present. Then CIAT has designed the machine in order that, if the unit is used the way it was designed for, there is no internal ignition source in the internal potentially flammable zone. Thus, the only residual risk is to have an ignition source introduced in the potentially flammable zone by the user. For that purpose, CIAT has decided to represent the external potentially flammable zone where the user must not introduce ignition source.
Although this information is believed to be accurate, it is presented without warranty of any kind, either express or implied. These are general recommendations and do not replace the installer’s individual advice and instructions for each specific site. CIAT shall not be liable if the information provided is not appropriate for a specific site and/or does not comply with applicable regulations. The manufacturer assumes no liability for actions taken by readers or users of this document that may cause unintentional damage or injury due to recommendations or inferences made from this document. The customer and the installer remain solely responsible ...

3 - HANDLING AND POSITIONING Installation over a pit R290 has a density higher than air. In case of leak, the main risk is stagnation in the lowest point. If unit is mounted in or over a pit, customer must ensure evacuation of gas is possible. Commonly used solutions (non-exhaustive list) are: ■...
3 - HANDLING AND POSITIONING 3.3.3 - Indoor installation In case unit is installed in an indoor space, installation requirements provided by EN378-3 standard must be applied. In that case, the potentially flammable zone generated by the unit is enlarged vs standard potentially flammable zone that is defined for outdoor use. All necessary protection required must be employed (detection and ventilation). Choice of used solution is under responsibility of customer, depending on site specificities. 3.3.4 - Variants and corresponding installation A high number of installation is possible. Here is a list of existing cases and the corresponding installation cases to report above. Variant Installation case to report to Sunken courtyard...
