Instructions for installation and use VX Solo II substations
6.0 Installation instructions, Safety and Handling
Instructions
Please read these instructions carefully before installing and comis-
sioning this substation. The manufacturer accepts no liability for loss or
damage resulting from failure to comply with these instructions for use.
Read and follow these instructions carefully to prevent the risk of physi-
cal injury and/or damage to persons and property. Exceeding the re-
commended operating parameters considerably increases the risk of
personal injury and/or damage to property.
Installation, commissioning and maintenance must be carried out by
qualified and authorized personnel in compliance with the local safety
regulations.
Once the station has been installed and is operating, there is normally
no need to alter the settings or other functions. The district heating
substation is very reliable and easy to operate.
Energy source
The substation is primarily designed for connection to district heating.
Alternative energy sources can be used if the operating conditions are
equivalent to district heating at all times.
Application
The substation is designed only to heat water and other heating media
may not be used.
The substation is to be connected to the household piping in a frost-free
room, where the temperature does not exceed 50 °C and the relative
humidity is not higher than 80%. The substation must no be covered,
bricked in or otherwise cut off from access.
Choise of materials
Only use materials, that comply with local regulations.
Corrosion
The maximum chloride compounds of the medium must not be higher
than 300 mg/l. The risk of corrosion increases considerably if the recom-
mended chloride content is exceeded.
Safety valve(s)
Installation of safety valve(s) must always be in compliance with local
regulations.
Noise level.
≤ 55 dB.
Storage
Before installation, the units must be stored in a dry, heated (i.e. frost-
free) room.
(Relative humidity max. 80% and storage temperature 5-70 °C).
The units must not be stacked higher than the limit at the factory (max.
8 layers) Units supplied in cardboard packaging must be lifted using the
handles incorporated in the packaging. Units must be placed on pallets
for transport/moving across large distances.
As far as possible, do not lift the substation by the pipes. Lifting by the
pipes may cause leaks. REMEMBER to retighten.
Disposal
Dispose of the packaging in accordance with the local regulations for
disposal of used packaging materials.
The substation is made of materials that cannot be disposed of together
with household waste.
Close all energy sources and disconnect all connection pipes. Disconnect
and dismantle the product for disposal in accordance with the applicable
local regulations for the disposal of the individual components.
Connection
It must be possible to cut off all energy sources to the unit - includ-
ing electrical connections - at all times.
Potential equalization/grounding
Potential equalization is an electrical equalizer connection to secure
against user contact with dangerous voltage, which may occur for
example between two piping systems. Potential equalization re-
duces corrosion in heat exchangers, water heaters, district heating
units and plumbing installations. Equalization of potentials should
be effected according to local regulations.
Warning! Hot surfaces
Parts of the substation may be very hot and can cause burn inju-
ries. Be very careful when you are in the immediate vicinity of the
substation.
Warning of high pressure and high temperature
The maximum supply temperature in the district heating network
can be up to 120°C and the operating pressure can be up to 16 bar.
This may result in a risk of scalding from touching the substation
and from outflow of the medium (water/steam). Exceeding the
substation design data and operating parameters for pressure and
temperature carries an appreciable risk of personal injury and/or
damage to property.
Emergencies
In the event of fire, leaks or other hazards, immediately shut off all
sources of energy to the substation, if possible and call for appropri-
ate assistance.
If the domestic hot water is discoloured or malodorous, shut off all
ball valves on the substation, notify all users and call for professional
assistance immediately.
Warning of damage during transport
On reception of the substation, and before installing it, check for
any evidence of damage during transport.
The substation must be handled and moved with the greatest care
and attention.
NB! - Tightening of connections
Before mounting of the substation, ALL pipe connections MUST
be retightened, as vibrations during transport may have caused
leaks. Once the substation has been put into operation ALL pipe
connections MUST be pressure tested for leaks and retightened
once more if necessary.
DO NOT OVERTIGHTEN THE PIPE CONNECTIONS – see page 19,
“Test & connections” for more information.
Handling
We recommend that you wear suitable safety footwear and suit-
able safety working gloves while handling and installing the sub-
station.
