The installation work must be carried out by an authorized installation
contractor. Before the system is taken into operation, it must be pressure
tested in accordance with relevant regulations.
The temperature and the pressure of the primary heating water are very
high.
Only qualified technicians
are allowed to work with the substation.
Incorrect operation may cause serious personal injury and result in
damage to the building.
If the hot water temperature is set too high, people may be scalded. If the
hot water temperature is set too low, unwanted bacteriological growth may
occur in the hot water system. This can result in serious personal injury.
Parts of the substation may get very hot and should not be touched.
When starting up the substation: To avoid the risk of scalding, make sure
that no-one draws any hot water until the hot water temperature has been
adjusted.
Start heating circulation by first opening the valves in the primary heating
supply and then return lines, in order to avoid pollutions in the system.
Open up the valves slowly to avoid pressure surges.
Before the substation is connected to the electrical supply, make sure that
the heating system is topped up with water. Starting up the system without
water will damage the circulation pump.
The substation comes prepared with an electrical plug to be connected to
the main supply. The strain relief clips of the cable must be fitted so that
there is no risk of damage. If necessary, the plug-and-socket connection
can be replaced with a permanent installation with an all-pole isolate
switch. This must be carried out by a qualified electrician.
