8. MOUNTING INSTRUCTIONS, GENERAL
The installation, connection and maintenance of the substation must
be performed by qualified and authorised personnel.
Installation must always be performed in accordance with the ap-
plicable legislation and in compliance with these instructions.
The substation must be installed so that it is freely accessible and can
be maintained without unnecessary disruption. Lift the substation
by its mounting plate/rear section and secure it to a solid wall using
2 sturdy bolts, screws or expansion bolts positioned in the two key-
holes in the mounting plate/rear section.
Before commissioning, rinse all the pipes in the household piping
system thoroughly to remove any impurities, and check and clean
the dirt strainers in the substation.
Connect the substation to the household piping in accordance with
the labelling at the bottom and/or in accordance with the instruc-
tions in this manual.
Test and connections
Before filling the system with water, retighten all the pipe connections
because vibrations and shocks during transport and handling may
have caused leaks. Once the system has been filled with water, tighten
all the pipe connections once more before performing pressure test
for leaks. After heating of the system, check all the connections and
retighten if necessary.
Please note that the connections features EPDM rubber gaskets!
Therefore, it is important that you DO NOT OVERTIGHTEN the
union nuts. Over-tightening may result in leaks. Leaks caused by
over-tightening or failure to retighten connections are not covered
by the warranty.
Heat meter, fitting pieces.
The substation is equipped with fitting pieces for heat meter on
the district heating return line.
Fitting of heat meters
- Close the ball valves on the district heating and the heating
sides.
- Loosen the union nuts at both ends of the fitting piece and
remove it.
- Fit the heat meter, - remember to insert gaskets.
- Mount sensor, - remember to insert gaskets.
- After mounting of heat meter remember to check and tighten
all pipe connections before commissioning the substation.
The heat meter
consists of flow meter, two temperature sensors for
mounting in DH supply and return and a microprocessor calculator
for the calculation of energy consumption. On the LCD display of the
calculator the energy consumption can be read.
