Installation
Requirements
WARNING!
The fusion PHE must
not be opened.
Installation in general
The installation must be provided with equipment
that protects the heat exchanger against pressures
and temperatures outside the approved minimum
and maximum values shown on the nameplate.
For best possible heat transfer performance, the
heat exchanger should be connected so that the me-
dia flow through the heat exchanger in opposite di-
rections (in counter-flow). Take into account the risk
of fire during the installation work, i.e. bear in mind
the distance to flammable substances.
Warning!
The heat exchanger must be installed and
operated in such a manner that no risk of
injury to personnel and damage to proper-
ty will be incurred.
Note!
Unless otherwise specified, product data
for normal refrigerants, i.e. HFC and HCFC,
are applicable to refrigeration applications.
The manufacturer must be specifically con-
sulted before the heat exchanger is used
for flammable, toxic or dangerous liquids
(e.g. hydrocarbons). The use must follow
the relevant safety rules for handling such
liquids. For further information, please refer
to the Internet site of the supplier.
Warning!
Safety valves should be installed according
to pressure vessel regulations.
Note!
Before connecting any piping, make sure all
foreign objects have been flushed out of the
system.
Foundation
Install on a flat foun-
dation giving enough
support to the unit.
Protection against
pipe forces
Fit the pipes so that no
tension is transferred to
the heat exchanger.
Protection against
overheating
Protect the heat ex-
changer by using a
heat-sink (welding
paste or tape) around
the connection before
welding operation.
