Termix VMTD-F-B - substation for direct HE and DHW
Electrical connection
Electrical connections must be made by an
authorised electrician only.
Electrical connections must be made in accordance
with current regulations and local standards.
Before making electrical connections, please note
the following:
- Please read the relevant parts of safety notes.
- The substation must be connected to 230 V AC
and earth.
- The substation must be electrically connected
so that it can be disconnected for repairs.
Filling, start-up
Prior to installation, all substation pipes and
connections should be cleaned and rinsed.
Before start-up, check that:
- pipes are connected according to the circuit
diagram,
- threaded connections are tightened.
When carrying out first fill, the heat exchanger
must be slowly filled with water until it reaches
working pressure.
The shut-off valves should then be opened and the
unit observed as it enters service. Visual checking
should confirm temperatures, pressures, acceptable
thermal expansion and absence of leakage. If the
heat exchanger operates in accordance with design,
it can be put to regular use.
All Danfoss heat exchangers and substations are
pressure tested prior to delivery.
