7.0 Troubleshooting
7.1 Troubleshooting in general
In the event of operating disturbances, the following basic features
should be checked before carrying out actual troubleshooting:
• the substation is connected to electricity,
• the strainer on the DH supply pipe is clean,
• the supply temperature of the DH is at the normal level
(summer, at least 60 °C - winter, at least 70 °C),
• the differential pressure is equal to or higher than the normal
(local) differential pressure in the DH network – if in doubt, ask
the DH plant supervisor,
• pressure on the system - check the HE pressure gauge.
