Installation
Before installation
Consider before installation
• Before connecting any piping, make sure all for-
eign objects have been flushed out of the piping
system that should be connected to the PHE.
• Before start-up check that all tightening bolts are
firmly tightened and that the correct measure-
ments of the plate pack, refer to PHE drawing.
• When connecting the piping system make sure
the pipes do not subject the PHE to stress or
strain.
• To avoid water hammer, do not use fast-closing
valves.
• In automated installations, the stopping and start-
ing of pumps and actuation of valves should be
programmed so that the resulting amplitude and
frequency of the pressure variation will be as low
as possible.
• If pressure variance is expected install efficient
dampers.
• Make sure that no air remains within the PHE.
• Safety valves shall be installed according to cur-
rent pressure vessel regulations.
• It is recommended that protective sheets are
used to cover the plate pack. Protect against
leakage of hot or aggressive fluids and the hot
plate pack
• For each model, design pressures and tempera-
tures are marked on the identification plate.
These shall not be exceeded.
