INSTALLATION
– OPERATING - MAINTENANCE
Do not use the pre-installed device connectors to pull the modules
together! If they are overloaded, they could be torn out or deform
the device.
Once the parts of the device have been connected, recheck the
position of the heat exchanger and if necessary readjust it. Once
installation is complete, seal the joints of the device rods and the
corners.
If the plate heat exchanger is installed via the operating or rear side
or module ceiling, the corresponding device profiles and housing
covers must first be dismantled. Insertion from the front with a
forklift truck or similar, from above with a crane or cable pull.
Here too, after installation, the joints between the plate heat
exchanger and housing must be sealed with sealant.
For large or multi-part plate heat exchangers that can only be
assembled on site, there is a two-part transport bracket. This must
be bolted to the heat exchanger and can be removed after
installation. Then seal the drill holes with sealant.

General
Commissioning, service and maintenance work is to be carried out
in an interconnected-circulation system according to guidelines
found in the chapter, Heat exchanger.
Commissioning
If the system is not going to be put into immediate service, then it
must be completely drained or filled with frost protection media to
protect the heat exchanger and pipelines from freezing.
The heat carrier medium must be checked for the effectiveness of
its frost protection before each winter period.
In order to prevent condensate icing on the discharge air heat
exchanger lamella-fins at low temperatures, it is necessary to
reduce the transmission capacity below the freezing limit.
Thoroughly ventilate the system when filling (multiple times, if
necessary) until all flowing sounds and air bubbles have
disappeared. Also vent the pumps and heat exchangers (internal
bleed valves). Filling must take place with an external circulation
pump as a basic rule. No warranty is honoured for dry-running of
the pump.
The static nominal pressure must be adjusted according to the
manufacturer’s
specifications (see data sheet).
Maintenance
-
Check pumps for damage, attachment, function and noise
-
Check fixtures for damage, leak-tightness and function
-
Check dirt collector screen for damage and clean
-
Check pipeline system for damage, leak-tightness and
attachment
-
Check fluid level and refill as necessary
