    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.

  • Page 6 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.
