* District heating (DH) - In the following
DH is specified as the heat source for the
substations. However, also other heat sources
such as an oil or gas boiler or solar heating
etc. could be used as the primary supply for
the fitted substations, enabling the Danfoss
Redan substations to be used in numerous
schemes with different energy sources,
depending on the local operating conditions.
In order to simplify we have decided to use
DH as designation for the primary supply.
Electrical connection
The flat station needs no electrical installation to
the main supply or earth grounding.
Filling, start-up
Prior to the Akva Vita TDP-F installation all its pipes
and connections should be cleaned and rinsed.
Before starting-up, check if:
- pipes are connected according to the circuit
diagram,
- release valves are shut-off,
- threaded connections are tightened.
The heat exchanger must be filled with water
so that the pressure slowly reaches the working
pressure.
After that the shut-off valves should be opened
and the operation of the heat exchanger must be
observed (e.g. temperatures, pressure, thermal
expansion, leakages). If the heat exchanger operates
operates unproblematically, it can be taken into
continuous use.
All Danfoss heat exchangers and flat stations have
been pressure tested prior to delivery.
