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 peroperty. Exceeding the recommended
operating parameters considerably increases the risk of personal injury
and/or damage to property. Installation, commissioning and mainte-
nance 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 operate with water or a water-glycol
mixture (up to 40%), 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.
PTC2+P controller for domestic hot water
The controller is preset from factory and sealed with a
red sticker. This sealing must not been broken.
The warranty becomes void if the sealing is broken.
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 - including
electrical connections - at all times.
Potential equalization/grounding
Potential equalization is an electrical equalizing connection to secure
against user contact with dangerous voltage, which may occur for ex-
ample between two piping systems. Potential equalization reduces
corrosion in heat exchangers, water heaters, district heating substa-
tions 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 injuries. 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 90°C and the operating pressure can be up to 10 bar. This may
result in a risk of scalding from touching the substation and from out-
flow 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 appropriate
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 assis-
tance 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 pipe connections MUST be tightened once more.
Handling
We recommend that you wear suitable safety footwear while
handling and installing the substation.
