Feed the temperature sensor [4] with the compensating spring [3]
into the sensor well [5].
Attach bracket [6] to DHW tank by means of 4 self-tapping sheet
metal screws [1].
Replace the cover of the aquastat [2].

5.4 Connecting the KS solar pump station
Attach the KS solar pump station [4] to the lower coil in the DHW
tank at the VS
1
(solar supply) and RS
1
(solar return) connections.
Attach the reheating device to the upper coil in the DHW tank at the
VS
2
(boiler supply) and RS
2
(boiler return) connections.
Use piping and pipe connections made of copper, brass and non-
galvanized steel for the connection between the KS solar pump
station [4] and DHW tank [5].

Grounding the piping
Attach one grounding clamp each to the supply and return pipes (at
any position).
Connect the grounding clamps to the building's grounding rod by
means of standard bonding cables AWG9.
Laying pipes with an automatic air vent valve on the roof (available
as accessory)
Pipes to the air vent valve should follow a rising gradient. For every
downwards change of direction, an additional air separator with air
vent valve is required (heat-resistant to 302 °F (150 °C)).
5.5 Connection as high-performance DHW tank
The DHW tank can also be used as a high-performance DHW tank.
In this case, 2 connection configurations are possible.
WARNING: Risk of equipment damage from very high
system temperatures and pressures!
Use pressure- and temperature-resistant piping
materials.
Do not use any galvanized piping, pipe connections
or graphite seals.
Do not use any plastic piping or connections of any
kind.
When using soldered connections in the entire solar
circuit, use high-temperature solder (melting point
455 °F (235 °C)).
To ensure proper operation of the solar thermal system,
air must be bled adequately from the entire system.
For information on bleeding the solar thermal system,
refer to the installation instructions for the KS solar
pump station.
