The assembly of the SolBox happens at the
three xing points at the back.
Prior to the beginning of the assemly it
is necessary to inspect the sustainability
of the building ground by the customer.
Subsequently, dimensions and style of
the xtures have to be adjusted and to be
provided by the customer.
After placing of the xtures, the SolBox has
to be hooked in the xing points and needs to
be secured.
Now install further pipelines in the solar
systems. Pay attention to the accurate
connection of the pipelines upon the collectors
- see illustration 6.
Connect the pipelines comming from the
collectors with the designated connections
(1) and (2) at the SolBox - see illustration 1.
Please pay attention that the pipelines have
to be installed with downgrade from the
collectors towards the SolBox.
notice total weight of 65 kg
Illustration 8
Connect the SolBox with the heat
exchanger in the storage tank. For this
purpose use the connections (6) and (10).
Please pay attention that the pipelines
have to be installed with downgrade from
the SolBox to the heat exchanger in the
storage tank.
Apply the prewired sensor at designated
place at the storage tank and secure it -
see illustration 2.
Install further sensors and wire these
with the solar controller - see assembly
instruction solar controller.
Plug in the power plug of the solar
controller - see illustration 2.

2) Please consider the size of the collector eld! For collector elds of more than 30 m², please ask for the
extension of the SolBoxn with your supplier.
For the combination with the SolBox, only self-draining collectors can be used. If you should
have any questions, please contact your supplier!

General
Now ll the system with a suitable glycol-water mixture via the lling unit on the SolBox using a lling
station.
First determine the lling quantity using the table on page 22.
Filling quantity = collector content + content pipes + content heat exchanger + content SolBox
Volumes
- The volume of the collectors is shown in the table on page 21.
- Refer to tables 4 and 5 on page 22 or the manufacturer’s specications for the volume of the lines.
- The volume of the heat exchanger can be taken from the information on the storage tank, the fresh
water station or the external plate heat exchanger.
- The SolBox has a volume of 40 l. When lling, make sure that the glycol-water mixture is pumped
into the system at room temperature (15° - 25°C).
