Make up water
Make up water is generally provided by a separate pressurisation unit placed in the system and
will work independently of the Lowara Servitec unit. In this case the water make up (port 3) can be
blanked off and not used. It is possible to connect a basic fill unit to the system for water make
which can be controlled by the Servitec unit, in this case the fill unit outlet should be connected the
Servitec make up port (Marked 3) maximum pressure 6 bar. The appropriate electrical connections
will also need to be made.
Initial start up
1. Check that the electrical connections are all made in accordance with local bylaws.
2. Check that the system connections have been made and the isolation valves are open.
3. Check that the pipe lines to the Servitec have been cleaned and are clear of any debris that
may have accumulated during installation.
Parameter Settings
