Termix VMTD-F-B

3.0 Safety notes

3.1 Safety Notes – general

The following instructions refer to the standard design of
substation. Special versions of substations are available on
request.

This operating manual should be read carefully before installation
and start-up of the substation. The manufacturer accepts no
liability for damage or faults that result from non-compliance with
the operating manual. Please read and follow all the instructions
carefully to prevent accidents, injury and damage to property.
Assembly, start-up and maintenance work must be performed by
qualified and authorized personnel only.
Please comply with the instructions issued by the system
manufacturer or system operator.

Corrosion protection

All pipes and components are made of stainless steel and brass.
The maximum chloride compounds of the flow medium should not
be higher than 150 mg/l.
The risk of equipment corrosion increases considerably if the
recommended level of permissible chloride compounds is
exceeded.

Energy source

The substation is designed for district heating as the primary
source of energy. However, also other energy sources can be used
where the operating conditions allow it and always are comparable
to district heating.

Application

The substation is designed to be connected to the house
installation in a frost-free room, where the temperature does not
exceed 50 °C and the humidity does not exceed 60%. Do not cover
or wall up the substation or in any other way block the entrance
to the station.

Choice of material

Choice of materials always in compliance with local legislation.

Safety valve(s)

We recommend mounting of safety valve(s), however, always in
compliance with local regulations.

Connection

The substation must be equipped with features that ensure that
the substation can be separated from all energy sources (also
power supply).

Emergency

In case of danger or accidents - fire, leaks or other dangerous
circumstances - interrupt all energy sources to the station if
possible, and seek expert help.
In case of discoloured or bad-smelling domestic hot water, close all
shut-off valves on the substation, inform the operating personnel
and call for expert help immediately.

Storage

Any storage of the substation which may be necessary prior to
installation should be in conditions which are dry and heated.

Authorized personnel only

Assembly, start-up and maintenance work must be performed by
qualified and authorized personnel only.

Please observe instructions carefully

To avoid injury to persons and damage to the device, it is absolutely
necessary to read and observe these instructions carefully.

Warning of high pressure and temperature

Be aware of the installation’s permissible system pressure and
temperature.

The maximum temperature of the flow medium in the substation is
120 °C.

The maximum operating pressure of the substation is 10 bar. PN 16
versions are available on enquiry.

The risk of persons being injured and equipment damaged increases
considerably if the recommended permissible operating parameters

are exceeded.
The substation installation must be equipped with safety valves,

however, always in accordance with local regulations.

Warning of hot surface

The substation has got hot surfaces, which can cause skin burns.

Please be extremely cautious in close proximity to the substation.
Power failure can result in the motor valves being stuck in open

position. The surfaces of the substation can get hot, which can cause
skin burns. The ball valves on district heating supply and return should

be closed.

Warning of transport damage

Before substation installation, please make sure that the substation

has not been damaged during transport.

IMPORTANT - Tightening of connections

Due to vibrations during transport all flange connections, screw joints
and electrical clamp and screw connections must be checked and
tightened before water is added to the system. After water has been
added to the system and the system has been put into operation,
re-tighten

ALL

connections.
