(e.g. NF C 15100 in France) and are under the responsibility of the installer. Failure to comply with the requirements of the above standards will void the CIAT warranty. It is your responsibility to protect the unit from mains voltage spikes and voltage spikes caused by lightning. Depending on the geographic location and the type of mains network (buried or overhead), you may have to install a lightning rod. - Page 12 Connections to be made before commissioning the unit Control In bypass only mode: terminal remove the jumper Common between terminals 4 and 5 Bypass 5 4 3 2 1 5 4 3 2 1 Frost protection or Heating/Cooling TERMINAL BLOCK J1 5 4 3 2 1 5 4 3 2 1 TERMINAL...

Page 13: Checks
Wire cross-sections and electrical specifications The cross-section of the cable must be selected with care based on: - the maximum current rating of the unit (see electrical specifications table below) , - the distance between the electrical box and Aqualis 2, - the ambient temperature. -
Page 14: Bleeding The Air
Pressure or temperature measurements requiring the use of gauges should be taken only if the unit malfunctions and doing so is recommended by CIAT’s After- Sales Service. To keep your unit running smoothly and to benefit from the warranty, take out a maintenance contract with your installer or an approved maintenance company. -
