6 Start-up
6.1 Run the start-up
1. Before starting up the product, read through the operat-
ing instructions.
2. Check that the electrical partition is installed.
3. Check that the hydraulic and electric connections are
correctly designed.
4. Check that a dirt filter is installed in the heat pump re-
turn.
5. Check whether an expansion relief valve, an expansion
vessel and a pressure gauge are installed.
6. Check the leak-tightness of the connections.
7. Open all the heating circuit valves.
6.2 Filling the heating circuit
Note
We recommend using ethylene glycol with corro-
sion-inhibiting additives.
If no frost protection has been poured in, the
product will not be protected in the event of a
power cut when there is frost.

▶ To purge the heating circuit during the filling procedure,
use a filling pump.
▶ Connect one end of the hose (3) to the drain valve.
▶ When purging, insert the other end of the hose (3) into
the mixing container (4).
▶ Open the filling valve using an open-end spanner (2).
▶ To purge the heating circuit, open the purging valve by a
1/4 rotation (B) using an open-end spanner.
▶ Increase the operating pressure in the heat pump heat-
ing circuit.
– Operating pressure: 0.15 … 0.2 MPa (1.50
… 2.0 bar)
Note
The pressure level may fall in the first month
following start-up. It may also vary depending
on the outside temperature.
Conditions: If you are using glycol
▶ The glycol must not escape into the outflow or the envir-
onment.
▶ Prepare a mixture with suitable glycol (max. 50% ethyl-
ene glycol) in order to protect the heat pump against
frost according to the regional minimum temperatures.
Note
If no frost protection has been poured in, the
product will not be protected in the event of a
power cut when there is frost.
▶ Use a frost protection tester to ensure the correct
dosage.
6.3 Treating the heating water
Caution.
Risk of material damage if the heating
water is treated with unsuitable frost and
corrosion protection agents.
Frost and corrosion protection agents may
cause changes in the seals, noises during
heating and may lead to further damage.
▶ Do not use any unsuitable frost and corro-
sion protection agents.
Mixing additives with the heating water may result in material
damage. However, no incompatibility with the units has been
detected to date with proper use of the following products.
▶ When using additives, follow the manufacturer's instruc-
tions without exception.
Note
Glow worm accepts no liability with respect to
the compatibility of any additive in the rest of
the heating system or its effectiveness.
Additives for cleaning measures (subsequent
flushing required)
– Fernox F3
– Sentinel X 300
– Sentinel X 400
Additives intended to remain permanently in the
system
– Fernox F1
