Hot water!
Risk of severe scalding.
Do not reach into the hot water when
emptying the Isomix.
Ensure that the Isomix has cooled
down before carrying out maintenance,
cleaning and repair work.
Install a suitable scalding protection
device at every tapping point (safety
shut-off valve, for example, or thermostat
mixer tap).
More detailed information on scalding
protection can be found in DIN 1988,
sheet 2, section 4.2.
During installation it must be ensured that the cables
from the pump and temperature limiter are not kinked.
The cables must not be under tension.
1. Fit the control station to the manifold with the 1” nuts and
associated seals.
The control station can be fitted on the right or left of
the manifold by turning the eccentric screw fitting.
2. Fit the temperature limiter to the supply collector pipe on
the manifold.
3. Connect the control station to the power supply.
Further information about electrical connection of
the control station can be found in the separate
documentation for the assemblies.
To ensure that the pump runs only
when heat is required, the manufacturer
recommends connecting the pump to
a pump relay (e.g. the pump logic of an
electrical control distributor that also
controls the actuators).
Alternatively, the pump can be operated
with a timer switch.
4. Set the temperature on the (optional) temperature limiter
to approx. 55 °C.
In the event of a fault, the temperature limiter
switches off the circulation pump and so avoids
overheating of the surface heating system.
5. Optional:
If all heating circuits are fitted with actuators and no
pump relay is used, the temperature limiter must be fitted
to the supply of the heating circuit manifold.
