LEGIONELLA BACTERIA
Legionella are small rod shaped bacteria which are a natural constituent of all fresh waters. Legionaries’
disease is a pneumonia infection caused by inhaling of Legionella species. Long periods of water stag-
nation should be avoided; it means the water heater should be used or flushed at least weekly.
The European standard CEN/TR 16355 gives recommendations for good practice concerning the pre-
vention of Legionella growth in drinking water installations but existing national regulations remain in
force.

INSTALLING NORMS (for the installer)
CAUTION: Observe all general warnings and safety standards listed at the beginning
of this text in full; all such instructions are obligatory.
The appliance must be installed and commissioned by a qualified technician in accordance with estab-
lished regulations and local health and safety regulations.
We recommend installing the appliance as close as possible to the delivery points to minimise heat loss
along the pipes. Local regulations may provide for restrictions on installation in bathrooms; observe any
regulatory minimum distances. The range of water heaters includes models set up to be assembled
above or below the point of use (sink, basin or shower). The models intended to be assembled under
the point of use are called “undersink”. To facilitate maintenance, make sure there is a clearance of at
least 50 cm inside the enclosure for access to the electrical equipment. Fix the supplied bracket to the
wall with screws and dowels of adequate size for the type of wall. Hook the water heater to the bracket
and pull down to make sure it is secured.
HYDRAULIC CONNECTION
The INSTALLATION of the appliance must strictly comply with SANS 10254 code of practice, a copy of
which is obtainable from the South African Bureau of Standards. Installation, maintenance and repairs to
the appliance not complying with the SANS 10254 code of practice will invalidate the Warranty.
If you decide to install mixer units (taps or shower), purge the pipes of any potentially damaging impuri-
ties first. The appliance must not be supplied with water of hardness less than 12°F, nor with especially
hard water (greater than 25°F); we recommend installing a water softener, properly calibrated and con-
trolled - do not allow the residual hardness to fall below 15°F. Before using the appliance, we recommend
filling its tank with water and draining it completely so as to remove any residual impurities.
Specific taps must be used for this type of installation and the connection must be implemented as
shown in the diagram in Fig. 1. With this solution, the water heater can work at any mains pressure and
no type of tap must be connected on the outlet pipe, which acts as a vent.
We reccomend that all exposed metal pipes must be lagged.
The hydraulic adaptors, which are delivered with the product, must be installed on the thread connection
with a sealing.
ELECTRICAL CONNECTION
Before performing any operations, disconnect the appliance from the electricity mains using the
external switch.
1. Electrical installation must comply with SANS 10142 – Electrical code for wiring of premises and should
be tested by the local electricity authority. The fixed wiring must incorporate a means of disconnecting
from the main supply having a separation of at least3 mm in all poles.
2. Check the circuit breaker on the distribution board is the correct amperage for the unit.
3. Check that all electrical connections are secure. with a sealing.
!WARNING! THIS APPLIANCE MUST BE EARTHED.
4. Replace electrical cover and ensure geyser is full of water before switching on electricity, even for
testing purposes.
5. Fixed wiring must incorporate a means of disconnecting from the main supply, having a separation of
at least 3 mm in a pole.

MAINTENANCE REGULATIONS (for competent person)
CAUTION: Observe all general warnings and safety standards listed at the beginning
of this text in full; all such instructions are obligatory.
NOTE: Elements burn through commissioning without water and burnouts due to loose connections are
not covered by the Warranty.
For greater safety, have qualified personnel carry out a careful inspection of the electrical system, ensur-
ing it complies with the applicable norms in force, because the appliance manufacturer will not be held
responsible for any damage caused by the lack of earthing of the system or for faults in the electricity
supply.
Check that the system is suitable for the maximum power absorbed by the water heater (please refer
to the data plate) and that the cross-section of the electrical connection cables is suitable and complies
with current laws. The use of multiplugs, extensions or adaptors is strictly prohibited. It is strictly forbid-
den to use the piping from the plumbing, heating and gas systems for the appliance earthing connection.
If the appliance is supplied with a power supply cable and the latter should need replacing, use a cable
featuring the same characteristics (type H05VV-F 3x1.5 mm², 8.5 mm in diameter) and compliant with
SANS 60227-5. The supply cable (type H05 VV-F 3x1.5 mm²) is to be inserted in the proper hole situated
in the back of the appliance and slide it until it reaches terminal of the thermostat, then lock single cables
by mean of the insulation base. To disconnect the unit from the electrical supply use a bipolar, switch
conforming to local (contact opening at least 3 mm, better if equipped with fuses).
The appliance must be earthed and the earth cable (which must be yellow-green and longer than that
of the phases it is fixed to the terminal marked by the symbol . Block the power supply cord on the
small cap using the special wire clamp provided.
Before usage, make sure that the supply voltage is in compliance with the rated values of the ap-
pliance. If the appliance is not supplied with a power supply cable, use a flexible cable (type H05VVF
3X1.5mm2, 8.5 mm) in diameter compliant with the applicable norms in force, if the applianche is sup-
plied with a cable clamp.
Startup and commissioning
Before powering up the appliance, fill the heater with mains water.
To do so, open the mains cock and the hot water tap until all the air has been vented from the
boiler. Check for leaks from the flanges, tighten down the fittings (not too much!) if necessary
(A fig. 4). Power up using the switch and in models with no switch, power up by turning the
adjustment knob clockwise
Maintenance work may only be done by qualified technicians (in possession of the regulatory requi-
sites). Before requesting for the Technical Assistance to intervene for a suspected fault, check that this
is not caused by a temporary lack of water supply or power failure.
Draining the appliance
Make sure to drain the appliance when it is out of service or in an area subject to subzero
temperatures.
To drain the appliance, proceed as follows:
- permanently disconnect it from its power supply;
- open the hot water tap (sink or bath tub).

Replacing parts
Disconnect the appliance from its power supply.
Remove the enclosure to access the electrical equipment.
To work on the thermostat, extract it from its mount and disconnect it from its power supply.
To work on the heating element and anode, first drain the appliance.
Use only original spare parts
Scheduled maintenance
The heating element (R fig. 5) should be descaled every two years to ensure it works properly.
If you do not wish to use a liquid descaler, you can simply break o the deposit, taking care not to dam-
age the heating element’s cladding. The magnesium anode (N fig. 5) must be replaced every two years;
however, the anode should be checked every year if the water is corrosive or chloride rich. To replace
it, remove the heating element and unscrew it from its bracket.
After routine or extraordinary maintenance, we recommend filling its tank with water and draining it
completely so as to remove any residual impurities.
Use only original spare parts supplied by the manufacturer’s authorised service centres.
Reactivating the two-pole cutout
If the water overheats excessively, a thermal cutout (CEI-EN compliant) trips to cut the electrical power
supply to the heating element (both phases); contact the Service Centre if this occurs.
USER INSTRUCTIONS
CAUTION: Observe all general warnings and safety standards listed at the beginning
of this text in full; all such instructions are obligatory.
