Notes
Safety in general:
Installation may only be carried out by qualif ied personnel in accordance with
the applicable regulations and standards. Improper installation can
lead to damage to the collectors and the entire system.
In addition to these important applicable standards, the national installation
regulations, legal regulations for accident prevention, environmental protection
and the professional associations must be observed, as well as the relevant safety
regulations of DIN, EN, DVGW and VDE.
Transport and storage
- store tubes and collectors in a dry place until installation and store them in
their packaging to protect them f rom damage.
The surface must be level.
- do not load the tube and collector cartons f rom above, except for identical
cartons. Stack a maximum of 7 tube cartons on top of each other.
- transport and store tubes and collectors horizontally, paying attention to the
top and bottom.
- handle full-vacuum tubes carefully and only touch them with cotton gloves.

lie completely on top, otherwise the housing
cover cannot be removed
- fasten foot part with washer and nuts
- align and tighten the nuts
- assemble collector / foot part in one alignment
- use a spirit level
- press down the cover (on the side of the toothing)

For all mounting types
Please also observe the corresponding mounting instructions of the
mounting system.

.
- put on gloves (cotton)
- spray the pipe penetration and the lower part of the
tube with a washing-up liquid mixture
- mount tube into the foot part with a slight turning
movement
Mounting the vacuum tubes
- all tubes must sit in one line in the collector
- insert the vacuum tube into the receptacles provided in the
collector while rotating it.
- insert the tube into the collector / sleeve until the
tube protection rubber is in contact and pull it
back approx. 5 mm f rom the collector.
- check the tight f it of the tube by gently pulling
of the tube
Hint:
To prevent overheating during installation of the system,
do not insert the vacuum tubes until the very end, after
f illing and the pressure and leakage test.
For roofs with southward deviation or perpendicular
mounting, turn absorber towards the sun.

Mounting the foot section side cover
Mounting of the connection
(rigid piping or corrugated hose)
- mount the left and right side covers to the base using
the screws provided
- mount rigid piping on collector inlet side with slight
rotating movement
- then mount the split side cover
- on the collector outlet side, mount the collector
connector with immersion sleeve with a slight rotating
movement.
- f inally mount the split side cover

Mounting the foot section cover
- mount the cover of the foot part again
- put on the lid and turn it downwards until the lid audibly
clicks into place
Important constant testing
- whether spring clips are seated correctly
- the entire locking system
page 11

Mounting the sensor
- insert the sensor into the sensor immersion sleeve
- connect with heat shrink tubing
- shrink the shrink tubing with a heat source or wrap it with the protective f ilm provided
Attention
The f ixed point of the pipeline should be determined when using rigid piping so that
suff icient expansion of the collector header pipe is possible. The rigid piping must NOT
be shortened. The continuing connections must be supported after a length of max. 15 cm.
Notes on the continuing pipeline
Do not solder on the collector and the supplied terminals. The design of the collector
must not be changed.
For installation, use only components that are suitable for the high temperatures that
occur, for example, gunmetal and brass f ittings, copper and stainless steel pipe.
When using hemp, use only pressure and temperature resistant solar sealant.
When using compression f ittings, all tube ends must be square and deburred. Push the
union nut and the clamping ring onto the tube and wet the threads with a little oil. Push
the tube as far as it will go into the compression f itting. First tighten the
union nut by hand and then tighten by ¾ turn.

Line up collectors
& Connecting the collectors
- f irst align a collector
- mount, then tighten fastening screws
- attach the following collector with the HP
collector connector to the mounted collector
- couple with slight twisting movements and light pressure
- check the locking by pulling lightly
- it maybe necessary to couple the respective following collector
turned 90° upwards and then swivel it into position
Important:
Collectors must be mounted in alignment with each other, otherwise leaks may occur.
page 13

Mounting the housing connectors
- mount the housing connector using the locknuts and
tighten them f irmly
Flat roof installation
The operating pressure (min. operating pressure) of the system P should be set in the cold
state (20°C) so that a pressure of 1.5 bar results at the level of the collectors (headers).
Observe the operating pressure
Pitched roof installation
Observe the angle of the collectors
see installation instructions for collector mountings -
f ree-standing (Art. no. 20070), f ree standing 10° (art. no. 20275)
see installation instructions for collector attachments - on-roof tile (art. no. 20084),
on-roof slate (art. no. 20200)
For a system for domestic water heating, we recommend the absorber
align 45° to the sun. With the combination of service water heating & heating
we recommend aligning the absorber at 60° to the sun.
Example:
The collector was installed at a height of 10 m above the membrane expansion vessel
(MAG). expansion vessel (MAG). P = (h x 0.1) + 1.5 bar, P = (10 x 0.1) + 1.5 bar corresponds to
P = 2.5 bar. The inlet pressure of the MAG should be set 0.3 - 0.5 below the system pressure
P in the depressurized state.
This is only a rough guide. Please use the easy system planner for the design, which you
can download at www.akotec.eu.

5Checklist
Important points in the overview, which are to be considered absolutely
1. Insert the vacuum tube into the collector with a rotary motion
2. Attention. Do not use automatic air vents for a solar system!
4. Setting the solar station
3. Filling the system
- S praying the tubes with a mixture of washing-up liquid and water makes tube
assembly easier.
- C heck locking by pulling lightly.
- Wear cotton gloves!
- common error, because it is common in a standard heating system.
- Automatic air vents can be destroyed by high temperatures.
Heat transfer fluid escapes, f rost protection is not guaranteed.
- Functionality of the system no longer guaranteed. Use air pots with manual bleed
screw.
- The heat transfer fluid must be f illed with an electric flushing pump/solar f illing
station. It is essential to observe a minimum flushing time of 30 minutes so that the
heat transfer fluid no longer contains any air pockets.
- The f illing quantity depends on the number of installed collectors and the pipe
lengths. Filling quantity values, see under point 4.
- set the solar station to a suff icient heat transfer fluid flow rate. The adjusted
volume flow must be set in the DeltaSol SLL controller (ltr. /h).

.Note
5. Expansion tank - dimensioning
6. Storage
8. Insulation
7. Controller
We expressly point out that the VT51 ready-to-use heat transfer fluid or a heat transfer
fluid tested by us must be used in order to ensure long-term safe operation.
- should be dimensioned between 50 l/m² and 70 l/m² gross collector area.
- if no AKOTEC controller is used: the alternatively selected solar controller must have
a vacuum tube collector function
- complete and suff icient insulation of the solar lines is mandatory
9. Lightning strike
10. Air pot
- for the correct dimensioning of the expansion vessel we recommend our easy system
planner (akotec.eu/english/easy-system-planner).
The collector array must be grounded against lightning in accordance with applicable
grounded in accordance with applicable regulations.
The air pot must always be mounted at the highest point as well as at the flow.
Maintenance instructions
The antifreeze content of the heat transfer fluid & the
safety devices (safety valve and MAG) must be checked annually! A regular function
check of the control and the electrical components is required!
The Weiser Protect without reflector also has absorbing vacuum tubes on the back.
The yield of the collectors can be increased by a reflective background on site, e.g. a
light-colored wall or reflective roof ing. reflective roof ing, the yield of the collectors can
be increased.
