18. COMMISSIONING CERTIFICATE
The substation is the direct link between the district heating supply network and the household piping system. All supply pipes and the
pipes in the household piping system must be checked and rinsed before commissioning. Once the system has been filled with water, all
pipe connections must be retightened before performing pressure test for leaks. The dirt strainers must be cleaned and the substation
must be adjusted in accordance with the instructions in this manual.
It is important to comply with all technical regulations and the applicable legislation in every respect.
Installation and commissioning must only be performed by trained, authorised personnel.
The substation is checked in the factory for leaks before delivery. Leaks are however possible due to vibrations caused by transport, hand-
ling and heating of the system and therefore it is important to check all connections and to retighten if necessarys before commissioning.
Please note that the connections may feature EPDM gaskets!
Therefore it is important that you DO NOT OVER-TIGHTEN the connections.
Over-tightening may result in leaks. Leaks caused by ove-rtightening or failure to retighten connections are not covered by the warranty.
