1 Important basic information
1.1 Following the operating instructions
➢ Please read the operating instructions thoroughly and in full.
➢ Ensure that the operating instructions are read and understood by all users who perform activities
associated with the plate heat exchanger.
➢ Always store the operating instructions in a manner that ensures that they can be accessed by all users at
any time.
1.2 Limits of the apparatus
The plate heat exchanger (PHE) is not a universal apparatus. It has been designed to be used in conjunction
with specific mediums, pressures, temperatures and operating characteristics. The plate heat exchanger is a
component that is meant to be firmly embedded in a system or machine. Once it has been installed, it serves
to transfer heat from a heat-emitting flow medium to a heat-collecting flow medium.
Spatial limits
The PHE must be freely accessible. Minimum distance to building parts, other machines or internal traffic
routes [► chapter 11.3]. The installation of the PHE requires a stable and level surface (foundation/steel
construction).
Temporal limits
Expected service life of the PHE: In case of envisioned cycling
of <= 1000 start-ups/shutdowns.
Demarcation of work responsibilities for mounting, installation, activation:
• Activation, installation, servicing and maintenance only by skilled workers who have received
instructions pertaining to the specific hazards.
• The operator should prevent the system from being accessed by unauthorised persons.
1.3 Technical data
Reference to the order-related technical data sheet in the annexe or, as the case may be, the name plate.
1.4 Prescribed environmental conditions
Risk of corrosion and contamination!
➢ Moisture and dirt may not be allowed to penetrate the PHE.
➢ Protect the PHE from dust, contamination, moisture, wetness, damage and other harmful influences.
➢ Do not store the PHE any longer than necessary. Store the PHE in the original packaging until it is
installed.
➢ Until the PHE is installed, ensure that it is protected from damage and stored at a protected location that
is not exposed to the effects of dust, contamination and moisture.
➢ Install the PHE in a manner that ensures that it is not damaged as a result of environmentally-induced
hazard sources. The installation procedure should also ensure that the functioning of the apparatus is not
disrupted by the actions of unauthorised entities.
➢ Position the PHE in a manner that ensures that it cannot be damaged by internal traffic or transportation
operations.
➢ Facilitate optimal monitoring of the PHE and optimal accessibility of the PHE:
- Position the PHE in a manner that ensures that it can always be monitored and checked from all sides.
- Ensure that there is enough room for servicing activities.
