M-K Compressor Expansion Automat
Installation and operating instructions
5. Installation
Use and the installation location are subject to binding regulations and provisions. Particular
reference is made to the obligation to inform test or certifi cation agencies prior to the installation
and starting of systems. In this case, the person responsible is to initiate the procedure with these
agencies. Documents, conditions and calculations arising from the tests carried out under the
procedure or other guidelines are to be observed when installing the system.
If acceptance procedures are required for the installed object, the system must only be started
once it has been confi rmed that the requirements imposed on the system have been satisfi ed.
- Perform the start/commissioning protocol.
Environmental conditions
The M-K Compressor Expansion Automats are to be installed in such a way that operation, testing
and maintenance can be constantly guaranteed. This automat must be installed in an enclosed,
frost-free room taking into consideration minimum distances (page 14; 13). The safe operating
temperature in the vicinity of the automat is 5...40 °C. Higher temperatures can lead to function
disruptions and to the overload of the compressor or compressors (no expansion). The placing
of the compressor intake and cool-air openings must ensure that surrounding parts cannot be
sucked in, an unobstructed fl ow of air is possible, and that no shorted fl ow between cool-air inlet
and outlet can occur.
Ensure that the expansion automat is operated in a surrounding atmosphere that is free of
electrically conducting gases, high concentrations of dust and vapours. A risk of explosion is
posed by combustible gases, gas mixtures.
Base and setup.
The installation surface must be prepared so as to ensure and maintain installation safety.
When preparing this surface, take into consideration the maximum weight of the complete
automat, including the weight of the water (page 13).
The guidelines of the responsible project leader of the total system apply. The following, general
rules must also be observed.
- Equipment to be installed must be completely removed from the packaging.
-
If the expansion automat (basic vessel) has been set up at the appropriate location and no
other changes to the location are required, the transport protection of the level sensor must be
removed. Avoid dust from coming into contact with this sensor and ensure a mounting surface
that does not obstruct the functioning of the sensor (platform). Avoid fi xing to the ground.
(Types of fi xing that impermissibly infl uence the automat, such as: pouring concrete or plaster
around the vessel feet, welds to the vessel or vessel foot, clamps and tighteners to the basic
body or suspending the automat are not allowed.)
-
Install now those accessories that are required for the expansion function (modules to the gas
and water compartments) which result in shutdown after start 56 (e.g. fl oatvent **
Flexvent Super, Pos.12, page 4).
-
Vertically adjust the vessel or vessels using the adjustable feet. Use a magnetic spirit level,
rotated by 90° for use in vertical positions.
- Ensure that no additional external loads impact on the system.
- Install expansion vessels and ancillary vessels at the same height.
-
When welding, do not allow welding materials to touch or enter equipment parts of the
expansion automat.
System connection
The system connection is to be manufactured as a connection to the heating system. Example
installations can be found on pages 15...18. Observe the following instructions before fi lling and
starting the M-K Compressor Expansion Automat.
- The connection should preferably be made in the return to the heat generator.
-
Ensure that this connection has a direct connection to the heat generator. Ensure that the
system connection of basic vessels is made only via the fl exible pressure hose delivered with
the system.
-
Install a shutoff device in the immediate vicinity of the automat-system connection, which can
be protected against unintentional closure and preferably comes with a fi ll and drain valve for
the water compartment of the vessel. If this item is missing, it must be installed separately.
-
If several expansion vessels are installed, an additional valve must be installed in the
expansion pipe in front of the collector pipe, which must also be secured against unintentional
closure.
-
Note that a temperature at the system connection greater than 70 °C (...90 °C) exceeds the
permitted diaphragm load and can result in the destruction of the diaphragm.
(Complete insulation of the expansion pipe can increase the load temperature.)
