Assembly – installation – connection
This unit must only be assembled, installed and connected by a locally approved professional in accordance
with all relevant standards and regulations.
1. Screw the screw-in heater element
into the opening in the tank provided (muff in most cases) with
1
R 1½" internal thread. Please use the flat seal
seal. The unit is best screwed in using a SW 60 open-ended socket wrench fitted externally to the hexa-
gon on the flange. The maximum torque used must not exceed 120 Nm.
2. Now fill the container and check that the heater element as fitted is not leaking, in accordance with the
appropriate guidelines. Check also for any leaks around the heater elements soldered in around the G 1½"
flange.
3. Now pull the U-section seal
over the disc-shaped connection end of screw-in flange G 1½" (external
3
diameter without U-section seal 76 mm, 2.5 mm thick).
4. Plug the cable
with one end to the flat sockets provided at the connection heater element ends.

5. Insert the rubber bush
in the large bore marked by the arrow in section 1 of the cover
10
the two flush bores to hold the thermostat.
6. Insert cable guide PG M20
in the bore provided for that purpose (20 mm diameter) in section 1 of
9
the cover
, using the locknut supplied. The maximum torque when tightening the screws must not
4
exceed 0.5 Nm.
7. Attach the thermostat
to section 1 of the cover
6
control shaft runs through the rubber bush already fitted and the body of the thermostat (asymmetric)
does not project beyond the outer edges of the cover at any point. The maximum torque when tightening
the screws must not exceed 0.5 Nm.
8. Now attach the control knob
to the thermostat control shaft
7
is flattened on one side) means this can only be done in one position: so turn the control shaft anti-clock-
wise with your fingers as far as it will go. Now push the control knob onto the control shaft until its base
is resting on the rubber bush
. Then rotate the control knob backwards and forwards while at the same
11
time pushing it downwards into the rubber bush until the control knob is sitting virtually flush on section
1 of the cover.
9. Extend the two spiral-shaped wound thermostat
Marry section 1 of the cover
to the heater
4
thermostat sensors into the pipe opening in the sensor protection tube in the centre between the heater
element connecting ends. Push the short, thicker sensor in first (its sensor line is also longer), then right
behind it the longer, thinner sensor with the rather shorter sensor line as far as they will go into the pipe
(min. 330 mm).

10. Now fit section 1 of the cover
and the assembled thermostat, with its half-shell in the shape of a
4
groove, onto the disc-shaped end of the screw-in flange fitted with the U-section seal
to top. To avoid damaging the U-section seal, press the inner walls of this half-shell outward slightly with
both thumbs. Please do not use force on any account, as you could destroy the cover otherwise.
11. Open the cable guide
and match the onion rings inside it to the connecting cable diameter you are
9
using to ensure class IP 54 protection.
12. Run your connecting cable professionally, in line with local regulations, through the cable guide in section
1 of the cover
, and fit it if you use multiple or fine-wire braids 1.5 or 2.5 mm, with the flat plugs
4
supplied to make the electrical connection to the thermostat. Check your connecting cable is not live!
13. Now connect the cable
attached to the heater element ends and the connecting cable you just fitted
8
to the thermostat, following the circuit diagram. The earth wire connects to the flat plug welded onto the
G 1½" screw-in flange of the heater
element, which is marked with the earth sign. The thermostat
1
must not be earthed.
14. Before closing the cover using section 2
5
pushed all the way into the sensor protection tube. Also check that no unprotected live parts are touch-
ing one another or could come into contact with any unprotected metal components or cover sections
1
or 2
.

15. Now close the cover by pushing on section 2
shaped end of the screw-in flange with the U-section seal. Check sections 1
mate properly with their all-round groove and spring system.
16. Now screw sections 1
and 2
of the cover together using the 4 x PT screws
4

maximum torque when tightening the screws must not exceed 0.3 Nm.
17. Check once again that the water tank is full. The water level must be at least 50 mm over the topmost
point of the heater. If the heater runs dry, this will destroy the unit immediately! The cover
must be fitted entirely outside the tank insulation for temperature reasons.
18. The unit can now be connected professionally to the power supply and used. Find the water temperature
you want empirically by turning the control knob to 'hotter' or 'colder'.
The unit is suitable for maximum water temperatures of 70-80°C (maximum setting). It is fitted with an all-
wire overheating cutout as a safety precaution, which cuts out permanently at temperatures between 95 and
110°C. If scale forms on the heater elements, this will destroy them prematurely: so the client should provide
suitable water softening facilities.
