are to be connected directly to the „L-SH+N"
terminals of the heat storage appliance. The
references marked * in the circuit diagram
opposite are to be taken into consideration
in this respect.
The heating elements in the appliance will
not be switched on until LF clearance is
issued by the electricity utility company,
and the electronic charging regulator issues
clearance for charging.
For operation with „single-wire con-
trol", a bridge is to be laid between
„N" and „A2/Z2".
Take proper note of the appliance rating
plate:
After the electrical connection has been
carried out, the connected load and the rat-
ed charging duration of the appliance are
to be marked in the appropriate boxes on
the rating plate and in the circuit diagram in
these Installation Instructions by ball-point
pen.
2.5.3 Appliance ready for operation
Cleaning the appliance K - L
The opened appliance is to be cleaned out
after the storage bricks have been set in po-
sition and used. To do this, the blower and
the air flow device are to be removed.
⇒ Unscrew the air flow device (13) and
draw it out.
⇒ Raise the blower fan (M1) slightly after
releasing the screws (do not unscrew) lo-
cated at the front of the retaining angle
element, and draw it out (pay attention
to the way in which the cables are laid).
With some appliances, to do this the
discharge temperature regulator (N5) is
to be unscrewed, including the retaining
plate.
When setting the dismantled parts aside,
care must be taken to ensure that the con-
nection wires are not damaged.
⇒ Clean the baseplate and blower fan (take
care not to damage the blades). Then
reinstall the blower, the temperature lim-
iter if applicable, and the air flow device
(make sure the cables are correctly laid).
Close the appliance M - Q
⇒ Suspend the inner front wall with the
thermal insulation, tilted slightly and
obliquely forwards, on the upper edge
and screw it to the lower edge;
⇒ Suspend the right-hand side wall in posi-
tion at the top and bottom;
⇒ Suspend the front wall in position at the
front, pivot it at the bottom towards the
appliance, and secure it with 3 screws (in
this situation, make use of the holes with
inside threads in each case);
⇒ fasten the air outlet grill with the two
lock-screws by a ¼-turn;
⇒ Hook in the upper edge of the air inlet
grill into the locking screws of the air-
channel-group, than push it on to the
lower catch-springs.

2.6 First start-up

Danger, short circuiting at the load
control
Be careful that teh test equipment probes
do not slip off of the contacts as this will
cause a shirt circuit and damage the load
control.
If this occurs, the control light will glow
green continuously!
2.6.1 Function test
The function of the blower fan for the stor-
age part is to be checked by switching on
the room temperature regulator.
2.6.2 Charging
Once the function test has been carried
out, the appliances can be taken into op-
eration without any particular additional
precautions. Charging is carried out either
manually by means of the adjuster of the
electronic charging regulator, or automati-
cally by means of the existing elthermaticc
charging control device.
During the first charging, the charge is to
be determined in kWh, and compared with
the maximum permissible charge from the
cold state as indicated in the Technical Data.
The charge which is determined must not
exceed the highest permissible charge from
the cold state.
At the first charging, a smell may be
apparent, and care should according-
ly be taken to ensure that the room is suit-
able ventilated (1.5 times air change, e.g.
window in tilted position). First charging in
a bedroom should as far as possible not be
carried out while anyone is sleeping in it.

Guarantee

The warranty conditions of our German companies do not
apply to appliances acquired outside of Germany. In countries
where our subsidiaries sell our products, it is increasingly the
case that warranties can only be issued by those subsidiaries.
Such warranties are only granted if the subsidiary has issued
its own terms of warranty. No other warranty will be granted.
We shall not provide any warranty for appliances acquired in
countries where we have no subsidiary to sell our products.
This will not affect warranties issued by any importers.

Environment and recycling

We would ask you to help protect the environment. After use,
dispose of the various materials in accordance with national
regulations.
2.7 Maintenance and conversion
of the appliance
In the event of re-installation of an appli-
ance which has been dismantled for the
purpose of repair, or which has already
been in operation elsewhere, the same
procedure is to be followed as for first-time
installation in accordance with these Instal-
lation Instructions.
In this case, particular attention must be
paid to ensuring:
- That any parts of the thermal insulation on
which damage or changes can be identified
which could impair safety must be replaced
by new parts. Before the appliance is tak-
en into operation, the insulation test and
measurement of the rated consumption
must be carried out.
2.7.1 Conversion of the appliance
The instructions provided with the individ-
ual fitting sets are determinant with regard
®
to conversion, extension, and installation
work.

Explain the functions of the appliance to
the new user. Draw their attention in par-
ticular to the safety instructions. Hand over
the Instructions for Use and Installation to
the new user.
