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 acci-
dents, 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 compli-
ance with the safety regulations (both heating and electrical work).
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 com-
pliance with local regulations.
Sound level.
≤ 55 dB.
Connection
The substation must be equipped with features that ensure that the
substation can be separated from all energy sources (also power
supply).
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 110°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 malodo-
rous, 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.
IMPORTANT - Tightening of connections
Before adding water to the system, ALL pipe connections MUST be
retightened, as vibrations during transport may have caused leaks.
Once the substation has been filled and the system has been put
into operation, ALL connections must be tightened once more.
(Do not overstrain! - See item 8.6, page 17)
3.0 Storage and Handling
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 . Units
supplied in cardboard packaging must be lifted using the handles incor-
porated 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.
Handling
We recommend minimum two people to lift the substation.
We recommend that you wear suitable safety footwear while
handling and installing the substation.
4.0 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.
