Recycling; Resolution Of Problem; Display Of The Regulator - Zodiac Pac Alpha 5M Notice D'installation Et D'utilisation

 during installation, troubleshooting and maintenance, pipes may not be used as steps: the pipe could break
under the weight, spilling refrigerant and possibly causing serious burns,
 when servicing the appliance, the composition and state of heat carrying fluid must be checked, as well as the
absence of any refrigerant,
 during the annual unit sealing test in accordance with applicable legislation, the high and low pressure switches
must be checked to ensure that they are securely fastened to the coolant circuit and that they cut‐off the
electrical circuit when tripped,
 during maintenance work, ensure there are no traces of corrosion or oil around cooling components,
 before beginning work on the cooling circuit, stop the device and wait for a few minutes before fitting the
temperature and pressure sensors. Some elements such as the compressor and piping may reach temperatures
in excess of 100°C and high pressures with the consequent risk of severe scalding.
4.2.2 Troubleshooting
 all soldering work must be carried out by a someone qualified to do so,
 replacement pipes must always be made of copper in compliance with standard NF EN 12735‐1,
 leak detection; pressure test:
- never use oxygen or dry air, risk of fire or explosion,
- use dry nitrogen or the mixture of nitrogen and refrigerant indicated on the information plate,
- the test pressure for both the high and low pressure circuits must not exceed 42 bar.
 the high pressure circuit pipes are made of copper and have a diameter equal to or greater than 1''5/8. A
certificate as indicated in §2.1 in compliance with standard NF EN 10204 will be requested from the supplier and
filed in installation technical documentation,
 technical data relative to the safety requirements of the various applicable directives must be indicated on the
information plate,
 This data must be recorded in the installation instructions for the device which are included in the installation
technical file: model, code, serial number, maximum and minimum OT, OP, year of manufacture, EC label,
manufacturer's address, refrigerant and weight, electrical parameters, thermo‐dynamic and acoustic
performances.
4.3 Recycling
This symbol means that your device must not be thrown in the bin. The device must be collected by a
selective system in view of re‐use, recycling or similar. Any substances it may contain which are
potentially dangerous to the environment shall be eliminated or neutralised.
Request information on recycling procedures from your retailer.
