1.5 General warnings
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.
1.6 Micro STC and Micro STC2 warnings
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.
Do not shut of the electrical supply to the room thermostat, this will damage the circulation pump,
valves, actuators etc.
