DYNACIAT LG 03 - 2017 Instruction manual

Prior to the initial start-up of the units, the people involved in the

on-site installation, start-up, operation and maintenance of this unit should be thoroughly familiar with these instructions and the specific project data for the installation site. The units are designed to provide a very high level of safety during installation, start-up, operation and…

All precautions concerning handling of refrigerant must be

observed in accordance with local regulations. Ensure good ventilation, as accumulation of refrigerant in an enclosed space can displace oxygen and cause asphyxiation or explosions. Inhalation of high concentrations of vapour is harmful and may cause heart irregularities, unconsciousness, or death.…

7. Periodic leak tests have to be carried out by the

customer or by third parties. The EU regulation set the periodicity here after: System WITHOUT leakage No Check 12 Months 6 Months 3 Months detection System WITH leakage No Check 24 Months 12 Months 6 Months detection Refrigerant charge/circuit 5 ≤ Charge 50 ≤ Charg Charge > < 5 Tons (CO2…

The accidental releases of the refrigerant, due to small

leaks or significant discharges following the rupture of a pipe or an unexpected release from a safety valve, can cause frostbites and burns to personnel exposed. Do not ignore such injuries. Installers, owners and especially service engineers for these units must: Seek medical attention before…
