•
Use sealants and pipework relevant to the installation; however, please observe at least the maximum permitted volumetric
flow, pressure and temperature values for the expansion line in question (control unit/system inlet and outlet).
•
Fit a non-return valve in the immediate vicinity of the system connection on the control unit that cannot be unintentionally shut
off.
Caution:
Close the lockshield valve at the system inlet and outlet of the control unit.
6.6 Electrical Installation
The provision of power supply, (protective) ground wire connection and line protection must be made in accordance with the
regulations of the responsible power company and the applicable standards. The required information can be found on the type
plate of the control unit, the terminal plan (labelling) and in Appendix 3.
The mains connection to be provided via a CEE plug/socket combination with load-switching ability. It should be a snap-on type,
to avoid unintended disconnections. For units with a total rated power above 3 kW (see Appendix 3) we recommend interlocking
this combination with a combined switch so that plugging or disconnecting is only possible if the switch is in the OFF position.
The separator should be marked accordingly, easy to handle and placed appropriately in the vicinity of the unit.
Hint:
install equipotential bonding between earth connection and equipotential bonding conductor. The minimum diameter,
quality and type of the power cables should apply to the on-site applicable rules and regulations for this application. The
electrical control terminals must be connected at the set-up location to the mains power supply at the relevant operating voltage.
The finished system allows the user to program the configuration and system-dependent parameters into the control unit.
