4.18 Maintenance and repairs
These services may only be carried out when the system is shut down or if the expansion automat is not required. The
pressurisation equipment must be taken out of service and guarded against unintentional re-starting until the maintenance
work is finished. Note that the safety circuits and data transmissions made whilst shutting down could trigger the safety chain
or lead to false information. Existing instructions for the heating or cooling unit as a whole must be observed. To stop hydraulic
components, block the relevant sections and drain them using the safe system water drains through the available drain
connections, and relieve the pressure.
Caution:
The maximum system water temperature in conducting components (vessel, pumps, casings, hoses, pipelines,
peripheral equipment) may reach 70 °C and, in the case of improper operation, may exceed that. This presents a danger of burns
and/or scalding.
The maximum pressure of system water in conducting components may be equal to the maximum set pressure for the applicable
safety valve. Vessel, nominal pressure 3 bar, safety valve max. 3 bar; pump unit nominal pressure 6; 10 or 16 bar:
Safety valve max. 6; 10 or 16 bar. Use of eye/face protectors is required if the eyes or face could be injured by flying parts or
spraying fluids.
To stop electrical equipment (control unit, pumps, valves, peripheral equipment), cut power to the control unit. The power supply
must remain off for the period of the work.
It is forbidden to alter or use non-original components or replacement parts without authorisation. Such acts may result in serious
personal injury and endanger operational safety. They will also render any claim for damages against product liability void.
It is recommended to contact Flamco Customer Service for carrying out these services.
4.19 Obvious misuse
•
Operation at incorrect voltage and/or frequency.
•
Use in inappropriate system designs.
•
Use of unpermitted installation materials.
4.20 Other hazards
•
Overload of construction parts by the presence of unpredictable extreme values.
•
Operational continuity at risk in the case of changed, non-permissible ambient conditions.
•
Operational continuity at risk in the case of safety-control parts being taken out of service or malfunctioning.
