3 Installation

Plate heat exchangers should be installed in such a way that there is sufficient free space around each unit
to carry out maintenance work, etc.
The plate heat exchangers can be installed in any position. However, when they are used as evaporators
or condensers they should be installed in a vertical position because performance may decline when they
are installed in another position.

4 Connection of pipes

NOTE
!
Piping must always be installed in such a way that no movement in the piping
and no unadmissible forces are transferred to the plate heat exchanger!
WARNING
Voltage flashovers
Electrocution hazard
Do not earth the heat exchanger when carrying out welding work!
The designation of the connections of the plate heat exchanger are marked on the name plate. The
connections for the primary and secondary side are described in the offer.
The plate heat exchangers are connected in parallel in counterflow. The cirquits to be connected should be
rinsed before carrying out the connection.
Piping to and from plate heat exchangers should be provided with shut-off valves. In addition, vent valves
should be provided in the upper connections at the highest point, and drain valves in the lower connections.
When connecting the plate heat exchanger it must be ensured that the gaskets of the connection bolts are
clean.
If there are brazed nozzles the heat exchanger must not be heated unnecessarily: brazing temperature
max. 650°C, do not hold the brazing flame towards the heat exchanger, use silver filler for brazing with a
silver content of at least 45%.
