8 Installation and commissioning
!
DANGER
Electrical energy!
Risk of death from electric shock.
• Work on parts carrying live voltage must be carried out
by qualified electricians only.
• Disconnect the power supply of the system and secure
it to prevent it from being switched on again before car-
rying out any installation, maintenance, cleaning or repair
work.
NOTICE
The installation and commissioning of
the Isomix-F must be carried out only by trained per-
sonnel who have been authorized by the manufacturer.
!
CAUTION
When repairing the unit or replacing
parts, be sure to observe the specified installa-
tion positions and flow directions of the parts being
replaced!
!
CAUTION
Material damage!
Pressure shocks may occur if the stop valve is opened
or closed quickly.
• Always open and close the stop valves slowly and in a
controlled way.
8.1 Installation
All screw fittings must be checked and tightened if
necessary prior to installation and commissioning!
For the torques of the fitting see „5 Technical data“
page 4�
!
WARNING
Hot water!
Risk of severe scalding.
Do not reach into the hot water when emptying the
Isomix-F. Ensure that the Isomix-F has cooled down
before carrying out maintenance, cleaning and repair
work.
During installation it must be ensured that:
• the cables from the pump and temperature limiter
are not damaged or kinked
• the sensor capillary tube is not damaged or 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 (5,
Fig� 8-1), also upside down�
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 documen-
tation for the assemblies�
4. Set the temperature on the (optional) temperature limiter
to approx. 55 °C.
NOTICE
To ensure that the pump runs only when
heat is required, the manufacturer recommends con-
necting 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 operat-
ed with a timer switch.
8.2 Mounting in combination with Heat
Interface Unit HIU 2
For use in combination with the Watts HIU 2 Heat Interface
Unit, the Isomix-F must be converted (overhead) and the
eccentric rotated.
1. Release nut (A, Fig. 8-1)
2. Rotate eccentric (5, Fig. 8-2)
3. Position the temperature limiter (8, Fig. 8-2)
