4 Prepare for installation
4.1 General Information
Warning!
The fittings are under pressure. Escaping pressurized
media can cause serious injury such as scalding or eye
damage.
Depressurise the system before performing any
installation work.
For retrofits to an existing system:
Drain the system or close the supply lines of the section
and depressurise it.
Warning!
Risk of injury due to the heavy weight of the unit:
Do not perform the installation alone.
Always wear safety shoes during the assembly. The unit
can be of considerable weight, depending on the
configuration. If the station falls over, this could lead to
injuries, particularly to the feet.
Caution!
Leaks in the unit may occur during transport or
installation. Check the nuts to ensure that they are
properly tightened before the connection to avoid
property damages.
Before installing the heat interface unit ensure that:
•
the primary pipes are laid in the building site.
•
the primary pipe installation is flushed and checked for leaks
•
the power and ground cables are routed to the installation site.
•
the unit is installed in a dry and frost-free room with an ambient
temperature lower than +40 °C.
•
the unit is mounted upright (not inclined, upside down or lying
down).
•
the unit is always easy to access even after the assembly.
