the accident prevention regulations of the trade associations.
IMPORTANT: Risk of being burned or scalded by hot
components! Install and replace collectors or collector parts
on very cloudy days. Perform installation work on sunny days
only in the morning or evening or with the collector covered.
IMPORTANT: Risk of being burned or scalded by hot solar
uid or components! Fill and ush the solar
system when the collectors are cold. Cover the
collectors while doing so.
IMPORTANT: Risk of being burned or scalded by escaping
hot steam! Steam can escape from the expansion relief valve
of the solar pump unit if the system is shut down. To avoid
injuries, you must connect the expansion relief valve to a
collecting container with a hose line.

System user instructions including Fluropro.
Installation and user instructions for the boiler.
Installation instructions for all sub components and
accessories used.
Warranty card.
Please observe the safety instructions in this manual when
installing this solar system.
IMPORTANT: A thermostatic mixing valve must be tted to
the outlet of the cylinder and can be adjusted to the desired
domestic hot water temperature by an installation or service
engineer. Otherwise there is a risk of scalding as the cylinder
outlet temperature at the taps could be up to 85°C.
IMPORTANT: Risk of being burned or scalded by escaping
hot steam! Steam can escape from unblocked automatic
bleeders if the system is shut down. Therefore block all
automatic bleeders after bleeding.
We recommend using the automatic air separator system
supplied as part of Glow-worm optional pipework kit. It works
fully automatically and does not need to be subsequently
blocked. It must be installed in an area however, in which no
steam can enter, preferably in the return pipe nearby the solar
cylinder.

1 System Specications
1.1 Intended use
The solar system is used for the solar-supported supply of
DHW.
Any other use is considered to be improper. The manufacturer
/ supplier is not liable for any resulting damage. The user
alone bears the risk.
Intended use includes the observance of the system
description and all other applicable documents, as well as
adherence to the maintenance and inspection conditions.
IMPORTANT: We accept no liability for any damage or injuries
caused by failure to observe this manual.
At the end of this manual is a commissioning protocol, which
should be lled in by the installer and/or commissioning
engineer and handed over to the user.
1.2 Design and function of the solar system
The solar system consists of four main components:
The collectors, which absorb the solar radiation and utilise it.
The solar control, which monitors, displays and controls all
functions of the system.
The solar pump unit, which transports the solar heat.
The solar cylinder.
The solar collector transforms solar energy into heat and
transfers the heat energy to a frost-protected solar uid.
The solar pump of the solar pump unit ensures the heat is
transported from the collector to the twin coil solar cylinder via
a pipe system. The solar pump unit is controlled by the solar
control.
The solar control switches the solar pump on or off as soon
as the difference in temperature between the collector and
solar cylinder falls below or exceeds the preset value. If the
solar energy is insufcient, the control system switches on the
boiler so that the upper third of the cylinder is reheated to the
set value for the domestic hot water temperature. In addition
the solar cylinder can be reheated by the immersion heater
installed by the manufacturer.
The solar expansion vessel compensates pressure
uctuations in the solar circuit.
On days on which the solar radiation is insufcient to heat the
DHW in the cylinder, the stored water must be reheated by a
heating system. This can be done with boilers or electrically
with an immersion heater.
The optional protection vessel protects the expansion
vessel from increased temperatures in the solar circuit. We
recommend installing a protection vessel.
Local authority planning permission may be required for
the installation. The local authority should be notied
about the intended installation.
The solar system is a closed system and must be bled
carefully. We recommend the automatic air separator
system for this purpose (item no. 0020054969). It works fully
automatically and does not need to be subsequently blocked.
The automatic air separator system must be installed in an
area in which no steam can enter, preferably in the return pipe
between the solar pump unit and the solar cylinder.

3.1 Solar pump station
Refer to diagram 3.1 for contents and description.
The solar pump unit is equipped with a three-speed solar
pump for the optimum adaptation of the required circulating
volume and the pump capacity in the solar circuit.
Select the pump capacity, depending on the solar system (e.g.
collector surface, pipe diameter, length of the solar circuit), so
that the actual ow rate is slightly higher than the nominal ow
rate. The ow rate meter is used for ne adjustment of the
ow rate.
The solar pump unit is delivered with a water control pack,
consisting of an expansion relief valve and a pressure gauge.
The ow rate meter installed in the return pipe is an essential
component of the solar system. To achieve optimum heat
transfer, you must achieve a certain ow rate, refer to section
5.2.
Upper deviations are not as serious as lower deviations.
Make the rough adjustments with the solar pump rst. You can
make the ne adjustments with the adjustment valve of the
ow rate meter. You can view the set value on the display of
the ow rate meter.
The ow rate meter has a ll/vent valve for lling and draining
the solar circuit.
NOTE: Do not under any circumstances set the ow rate
below the calculated ow rate. The collector efciency will be
considerably reduced.
If you would like to use the solar exible pipework (DN16
0020054964) from the pump station to the cylinder, please
order an additional two ttings packs, part No. 0020054965,
these contain the relevant ttings for this application.

3.2 Solar expansion vessel
The solar expansion vessel, is used to equalise the pressure
while the pressure relief valve blows off the solar uid into
the collecting container via the pressure release pipe if the
operating pressure of 6 bar is exceeded.
The size of the solar expansion vessel is based on the
expansion volume of the solar system.
The expansion vessel not only accommodates the expansion
volume of the solar uid, but also the entire volume of the
collectors in the event of a shutdown. The total volume of
the solar system is the total of the individual values of the
collector, heat exchanger volume and the volume of the
pipeline.
The admission pressure of the solar expansion vessel can be
set between 0.5 and 4.0 bar.

3.3 Thermal cut out of the solar pump
The solar pump must be protected by its own thermal cut out
(TCO) which must be mounted on the solar cylinder (preassembled at the factory on the Glow-worm Flurocyl cylinder).
The power supply to the pump MUST be interrupted at
cylinder temperatures higher than 90°C.
3.4 Solar fluid
This information applies to Glow-worm solar uid (20 l
canister: item no. 0020054968).
Glow-worm solar uid is a ready-mixed antifreeze and
anticorrosive, consisting of approximately 45% propylene
glycol with anti-corrosion inhibitors and 55% water. It is
resistant to high temperatures.
Furthermore the solar uid has a high thermal capacity.
The inhibitors provide reliable corrosion prevention when
using different types of metal (mixed installations).
NOTE: Do not use any other anti-freeze or inhibitors with the
collector. Only Glow-worm solar uid is approved.
IMPORTANT: Risk of damage! Glow-worm solar uid is ready
mixed. You may not under any circumstances mix it with water
or other uids. Otherwise it will become ineffective as an
antifreeze or anticorrosive, resulting in damage to collectors or
other parts of the system.
Glow-worm solar uid is innitely durable in hermetically
sealed containers.
Skin contact is normally not dangerous. Eye contact only
causes minor irritations, you should nevertheless immediately
wash your eyes.
Observe the safety data sheet, see section 9.
3.5 Protection of the solar circuit against frost
and corrosion
To protect the solar system reliably against frost in winter, the
entire solar circuit must be lled 100% with solar uid.
NOTE: You can achieve frost resistance of about -28°C by
lling the solar system with Glow-worm solar uid. No damage
is caused by frost even at outside temperatures below -28°C,
since the expansive effect of the water is reduced. Check the
antifreeze effect after lling the system and then once a year.
To check the solar uid; refer to the operating manual of the
solar uid tester (item no. 0020054984).

4.2 Fitting the solar pump station
(wall-mounted installation)
Fit the wall bracket and the pump station ow and return
assemblies.
Secure the assemblies in the wall bracket using the two C-
clips. Put them onto the ow and return assemblies below the
wall bracket.
4.3 Pressure relief valve and expansion vessel
Fit the pressure relief valve assembly to the connection nozzle
in the pump station return tube assembly.
IMPORTANT: Loss of solar uid! Install a discharge pipe from
the pressure relief valve outlet to a container to ensure that
any hot solar uid escaping from the system is contained.
The solar uid container is intended as a collecting container
when the system is lled and the container is empty. Connect
a discharge pipe from the relief valve outlet to the intended
location for the container.
Mount the expansion vessel wall bracket using screws and
plugs. Screw the ange and the expansion vessel to the wall
bracket.
The expansion vessel must be mounted vertically and the ow
from the system must enter the vessel from the top. To avoid
accidental spillage or access by children to the uid, best
practice is to take the discharge pipe right to the bottom of
(but not touching) the container.
The empty solar uid container is recommended, as reusing it helps to reduce landll, the contents of the container
are visible (you must be able to see if the safety valve has
discharged) and offers a practical solution. However, if
preferred, an alternative vessel may be used, provided it is
of adequate size, the contents are visible and it is not fully
sealed.
4.4 Notes on the solar circuit pipework
When installing solar circuit pipework between the collector
array and the cylinder, carefully consider the location of
the pump station and the requirement for an automatic air
separator. The Glow-worm solar system is a closed hydraulic
system in which heat can only be transferred to the cylinder
by means of special heat transfer uid in the solar system.
Observe the following points to ensure perfect operation with
maximum energy utilisation:
Bleed the system completely during commissioning and
servicing since air in the system has a considerable effect on
the efciency.
The pipe diameters should not be too large, otherwise the
the ow in the solar system will slow down, reducing the
efciency.
Lay all system components in such a way to ensure an even
ow at the required nominal ow rate.
Provide sufcient thermal insulation of the pipes to prevent
excessive heat loss. The insulation must withstand
temperatures up to 150°C. Select weather and UV resistant
insulation which is “bird peck proof“ especially for pipes laid
outside.
When using compression ttings, you must consult the
manufacturer of these ttings to check their suitability for solar
systems.
Use compression ttings only if temperatures of up to 200°C
are allowed by the manufacturer.
IMPORTANT: Use hard solder only, soft solder is NOT
suitable.
Do not use any plastic pipes.
Flexible stainless steel pipes supplied by Glow-worm or
copper pipes should be used for the solar circuit.
Optional Glow-worm exible pipes for the connection of the
collectors to the solar pump unit.
0020054994: 2 in 1 exible pipe DN 16 x 15 m
0020054964: single exible pipe DN 16 x 15 m
Two single exible pipes DN 16 x 15 m are available as part
of the Glow-worm optional pipework kit. Instructions for the
connection of these exible pipes can be found in separate
installation instructions.
Due to the occasionally high temperatures of the solar uid,
plastic pipes must not be used for the solar circuit. Copper
pipes must be joined using hard soldering or compression
ttings. Soft soldering is NOT suitable.
Teon tape can be used on pipework below the Solar Pump
Station.
IMPORTANT: Earth the solar circuit!
The solar pipework must be earthed in accordance with the
requirements of BS 7671 IEE Wiring Regulations. Wiring
protection should be provided if there is high risk of lightning
strikes. The electronics in the solar system, heating system or
in the house could otherwise be destroyed if they were to be
hit by lightning. Connect the collectors to an existing lightning
protection on the house.
IMPORTANT: Risk of damage to the collectors due to
excessive pressure. The installation of a motorised 2 port
valve in the pipes of the solar system is not allowed, since the
safety devices in the solar circuit could be overridden by it.
The right selection of the pipe diameters plays a signicant
role in terms of maximum efciency of the solar system.
To keep the pressure loss in the solar circuit to a minimum,
the ow velocity in the copper pipe should not be higher than
1.5 m/s.
A nominal ow rate of 0.66 l/min per net m
required by the collectors to achieve optimum heat transfer.
Another decisive criteria for the optimum operation of your
solar system is the speed of the solar pump. The pump must
be able to deliver more than the nominal ow rate at the
specied operating pressure. The selection of the required
pump speed depends on the installed system. Reference
value for the pump selection can be found in section 5.2.
Connections to solar pump station
IMPORTANT: An air separator is required - refer to diagram
4.5.
Using the compression ttings supplied with the pump station,
connect the pump station ‘ow’ assembly to the collector ow
pipe and the pump station ‘return’ assembly to the collector
return pipe. IMPORTANT: ensure the collector pipes are
connected correctly - the pump station ‘return’ assembly
includes the pump.
Use the ttings included to connect to 22mm copper pipes.
Again using the compression ttings supplied with the pump
station, connect the pump station ‘ow’ assembly to the
cylinder ‘solar circuit ow’ connection then the pump station
‘return’ assembly to the cylinder ‘solar circuit return’.

4 Installation
IMPORTANT: Ensure the cylinder pipes are connected
correctly - the pump station return assembly includes the
pump.
4.5 Automatic air separator
Air in the system impairs the efciency of the solar system
considerably. Install an automatic air separator in the return of
the solar circuit, between the cylinder and solar pump station.
High temperature vapour is unlikely in this area. However,
check with the manufacturer that the device is suitable for
domestic solar system applications.
A suitable and effective air separator is supplied in all
solar packs or separately (item no. 0020054969). This is
recommended.
The air separator system works fully automatically and does
not need to be isolated.
The system must be bled whenever it is lled or subjected to
maintenance. Bleeding is performed constantly by means of
the automatic air separator system as long as the solar pump
is in operation.

You must adhere to the following procedure for the
commissioning of the total system:
Use only Glow-worm solar uid (item no. 0020054968) for
pressure tests and for ushing and lling the solar circuit.
5.1 Flushing and filling the solar circuit
Glow-worm recommends using the Glow-worm lling pump,
part no. 0020054986, to ush and ll the solar circuit. Observe
the separate user manual when using the Glow-worm lling
pump.
Expansion vessel admission pressure
During the commissioning, the gas side admission pressure
p
of the expansion vessel must be adjusted to the equipment
v
height whilst disconnected. The static pressure p
corresponds, to a certain extent, to the static height h between
the collector array and the expansion vessel.
10m static height correspond to approx. 1 bar.
p
= p
= h x 0.1 but not less than 1.5 bar.
v
stat
NOTE: A deviation from the optimum admission or lling
pressure always results in a reduction of the expansion
vessel's effective volume. This can cause operational
malfunctions.
Flushing is performed from the solar pump station to the
cylinder via the collector.
A self-priming pump with a pressure of 2 to 3 bar is required
to ll the solar circuit.
Collector circuit lling pressure
The lling pressure Pa should be approx. 0.5 bar over the
static pressure Pstat.
Pa = h x 0.1 + 0.5 bar but not less than 2 bar.
stat
EXAMPLE: The installed (net) collector surface area for
Clearly Solar collectors is 2.35 m2. Multiplied with the value
for the specic ow rate of 0.66 l/m2 • min, it results in a
calculated ow rate, which should be indicated by the ow
rate meter, see diagram 5.1.
Select the next pump speed if the calculated ow rate is not
achieved on the ow rate meter. Switch to a lower speed if it
is exceeded. If the ow rate cannot be achieved even at the
highest pump speed, check whether it is possible to use fewer
collectors in series reverting to a combination of series and
parallel connections (eg 2 collectors in series in parallel with
an additional 2 collectors in series).
Use an Allen key to nely adjust the ow rate at the
adjustment valve, see diagram 5.1.
The adjusted ow rate can be viewed on the display, see
diagram 5.1.
Table 5.1 provides reference values for possible pump speeds
depending on the collector connection and pipe length and
cross-section.
The ow rate can be used to calculate and display the
gain. To make an accurate calculation, the ow rate must
be entered into the Fluropro solar control. You can nd
further information in the separate system wiring instructions
including the Fluropro solar control.
The pump speed is used to achieve a particular ow rate
in the collector array. The nal ow rate should not be
signicantly above or below the calculated value. Up to 10%
lower solar gain or unnecessarily high power consumption of
the pump could occur.
5.2 Setting the flow rate / pump speed
The 3-speed circulating pump can be ne-tuned to adjust the
ow rate to the collector's performance.
NOTE: We recommend a value of 0.66 l/min per m2 collector
surface area.
This is how to do it:
Use Table 5.1 to calculate the ow rate to be set by
multiplying the installed collector surface area with the value
of 0.66 l/m2 • min.
Set the pump speed to roughly set the ow rate as follows:-
1,1 l/min
Let the pump run rst at the lowest speed (minimum power
consumption).
Check whether the calculated value is achieved on the ow
rate meter.

The pressure gauge indicates a drop in
pressure.
The water pressure and amount of
discharged water decreases at hot water
taps.
The system is making noises. Normal in
the rst few days after lling the system.
If it occurs later, there are two possible
causes:
The solar gain is unusually low. The pipe insulation is too thin or incorrect.
Solar control
Display example “NTCA Err“ or similar
(reference system wiring instructions
including Fluropro solar controller)
Solar cylinder
The cylinder cools down at night. The
ow and return temperatures vary after
switching off the pump. The collector
temperature is higher than the air
temperature at night.
Reheating is not working. The boiler
runs for a short time, goes off and then
back on again. This is repeated until the
cylinder is at its target temperature.
A drop in pressure is normal shortly
after lling the system, since air still
escapes from the system. If a pressure
drop occurs again later on, the cause
may be an air bubble, which has been
subsequently released.Furthermore there
are uctuations to the pressure in normal
operation mode between 0.2 to 0.3 bar,
depending on the system temperature. If
the pressure drops continuously, there is
a leak in the solar circuit, in particular in
the collector array.
