8.2 - GENERATOR SHUT-DOWN DURING WINTER
• 2 possibilities:
1) Drain the unit and disconnect the power supply.
GB
2) Unit full of water and power on: as the unit is equipped with an antifreeze device which actuates the water circulating
pump when the temperature drops below zero, it is imperative to ensure that the water can circulate within the unit.
9 - TROUBLESHOOTING
• All maintenance and servicing operations on the refrigerating circuit must be conducted in accordance with standard trade
practices and safety rules: recovery of the refrigerant, inert shielded (nitrogen) brazing, etc...
• All brazing operations must be conducted by qualified welders.
• For equipment loaded with R 407 C, refer to the specific instructions at the beginning of the installation manual.
• This unit is equipped with pressurised equipment, for example piping.
Use only genuine parts listed in the spare parts list for replacing defective refrigeration components.
• Pipes may only be replaced by copper tubing in compliance with standard NF EN 12735-1.
• Leak detection, in the case of pressure testing:
- Never use oxygen or dry air, as the risk of fire or explosion is present.
- Use dehydrated nitrogen or a nitrogen and refrigerant mix indicated on the manufacturer's plate.
- For units equipped with pressure gauges, the test pressure must not exceed the gauges' maximum allowable pressure
rating.
• All part replacement with other than genuine parts, all modifications of the refrigerating circuit, all replacement of refrigerant by
a fluid other than that indicated on the manufacturer's plate, all use of the unit outside the application limits defined in the
documentation, shall result in the cancellation of PED EC marking compliance which shall fall under the liability of the individual
who carried out these modifications.
• The technical information, relative to the safety requirements of the various applicable directives, is indicated on the
manufacturer's plate of the unit and mentioned on the 1
