4 Installation
4.1 Before installation
CAUTION
During installation or maintenance, precautions must be taken to avoid
damaging the heat exchanger and its components. Damage to
components can adversely affect the performance or serviceability of the
heat exchanger.
To consider before installation
• Before connecting any piping, make sure all foreign objects have been
flushed out of the piping system that should be connected to the heat
exchanger.
• Before connecting any piping, make sure that all the bolts for the feet are
tightened and that the heat exchanger is firmly fixed to the foundation.
• Before start-up, check that all the tightening bolts are firmly tightened and
that the plate pack has the correct measurements. Refer to the PHE
drawing.
• When connecting the piping system, make sure the pipes do not subject
the heat exchanger to stress or strain.
• To avoid water hammer, do not use fast-closing valves.
• Make sure that no air remains inside the heat exchanger.
• Safety valves shall be installed according to current pressure vessel
regulations.
• It is recommended that protection sheets are used to cover the plate pack.
Protect against the leakage of hot or aggressive fluids and the hot plate
pack.
• If the heat exchanger surface temperature is expected to be hot or cold,
take protective actions, such as insulate the heat exchanger, to avoid risk
for personnel injuries. Always ensure that required actions are according to
local regulations.
• Design pressures and temperatures for each model are marked on the
name plate. These shall not be exceeded.
