Instructions VX Solo II
2.0 Safety notes
Instructions
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. The risk of persons being injured
and equipment damaged increases considerably if the recommended
permissible operating parameters are exceeded.
Installation, assembly work, first start-up and maintenance work may
be carried out only by qualified and authorized personnel in compliance with the safety regulations (both heating and electrical work).
Connection
The substation must be equipped with features that ensure that
the substation can be separated from all energy sources (also
power supply).
Warning of hot surfaces
Parts of the substation may become hot and hot surfaces can
cause serious burns. Please be extremely cautious in close proximi-ty to the substation.
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 only to operate with water or a water-glycol
mixture (up to 40%), and other heating media may not be used.
Connect the substation to the house installation in a frost-free room,
where the temperature does not exceed 50 °C and the humidity does
not exceed 80%. 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.
Corrosion protection
The maximum chloride compounds of the flow medium should not
be higher than 300 mg/l. The risk of equipment corrosion increases
considerably if the recommended permissible chloride compounds
are exceeded.
Safety valve(s)
We recommend mounting of safety valve(s), however, always in compliance with local regulations.
Sound level.
≤ 55 dB.
Warning of high pressure and high temperature
The stations work at a maximum supply temperature from the
district heating network of 110°C and the stations work with a operating pressure of 16 bar, which may put the user at risk of burns
from touching the surface or from the emissions of hot media
(water/steam). The risk of persons being injured and equipment
damaged increases considerably if the recommended permissible
operating parameters are exceeded.
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.
Warning of transport damage
Before substation installation, please make sure that the substation has not been damaged during transport. Always transport
the substation with the utmost care and caution.
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.
(Do not overstrain! - See item 7.2)
3.0 Storage and Handling
If the substation is stored before installation, make sure that the place
is dry and heated.
(Humidity max. 80% and storage temperature 5-70 °C).
Do not stack the unit higher than factory shipped. Units that are
shipped in cardboard packaging are to be lifted by the carrying
handles of the packaging. Transport / removals over great distances
should be carried out on pallets.
During and after unpacking, the substation can be lifted by using
straps, fitted around the pipes or it can be lifted by hand in the
pipes Lifting in the pipes can cause leaks. ALWAYS re-tighten.
Handling
When working on the substation suitable safety shoes must be
worn.
4.0 Disposal
Dispose of packaging material in accordance with local regulations.
This product consists of materials, which must not be disposed of
together with domestic waste. Switch off the complete power supply and dismantle the product and sort the components in various
groups before disposal. Always observe the disposal rules of the local
legislation.
