4 Installation
4.1 Before installation, lifting and transport
CAUTION Risk of damage to equipment.
During installation or maintenance, precautions must be taken to avoid
damaging the plate heat exchanger and its components. Damage to
components can adversely affect the performance or serviceability of the
plate heat exchanger.
WARNING Risk of personal injury.
The equipment is heavy.
Never lift or move the equipment manually.
To consider before installation
• Keep the plate heat exchanger packed until installation.
• Before connecting any piping, make sure all foreign objects have been
flushed out of the piping system that should be connected to the plate heat
exchanger.
• Before start-up, check that all the tightening bolts are firmly tightened and
that the plate pack has the correct measurements. See the PHE drawing.
• When connecting the piping system, make sure the pipes do not subject
the plate heat exchanger to stress or strain.
• Avoid vibration, install any anti-vibration equipment if necessary.
• The plate heat exchanger connections on the follower and connector grids
have little strength against pipe work or nozzle loads. Such loads can arise
for example from thermal expansion. Proper care must be taken to avoid
transfer of such pipe forces and moments to the plate heat exchanger.
• To avoid water hammer, do not use fast-closing valves.
• In automated installations, the stopping and starting 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 inside the plate 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.
• Design pressures and temperatures for each model are marked on the
name plate. These shall not be exceeded.
