6 Instructions for use and maintenance
If the standard water mains pressure exceeds the value
pointed out in the above paragraph I, then it is necessary
to fit a pressure reducing valve (not supplied) for the
heater to function correctly.
The Manufacturer does not accept any liability for
problems arising out of the appliance’s improper use.
3. Water heater‘s electrical connection (fig.3)
ATTENTION! Before you switch the power supply, make
sure the appliance is full of water.
3.1. Models fit with power supply cord combined with a
plug shall be plugged in a socket. The boiler can be
disconnected from the power supply by unplugging.
ATTENTION! The wall-plug must be properly connected to
a separate electrical circuit fitted with a circuit breaker. It
must be earthed.
3.2. Water heaters fitted with a supply cord without a plug
The appliance has to be connected to a separate electrical
circuit of the stationary electrical wiring via a hard wired
connection.
A safety fuse (16A) (20A for power > 3700W) and RCD or
similar should be used to ensure safety.
The connection of the conductors of the power cord of the
appliance is as follows:
•
conductor with brown insulation – to the phase
conductor of the electrical wiring (L)
•
conductor with blue insulation- to the neutral
conductor of the wiring (N)
•
conductor with yellow-green insulation – to the safety
conductor of the wiring ( )
VI. OPERATING THE DEVICE
Before initial start of the device, please make sure that
the water heater has been correctly connected to the
electrical network and that it is full of water.
Switching on the water heater is done through the device
incorporated in the installation, which is described in
subitem 3.2 of paragraph V, or by inserting the plug into
an electrical socket (for models with cord with a plug).
Clarification to Fig. 6:
Operation modes:
1. Position ( ) anti-freezing mode
WARNING: The electrical power supply of the device
should be switched on. The safety valve and the pipe
connecting it to the device must be secured against freezing.
2. Position ( ) maximum temperature
3. Position ( ) at this mode the water temperature
reaches about 60°С. In this way heat losses are
reduced.
4. Light indicator – at heating mode it is lit in red, and it
is lit in blue when the water has been heated up and
the thermostat has switched off.
5. Regulator knob – for temperature setting
Water heaters with electrical-mechanical POP-UP
operation
1. Push the knob to pop-up Fig. 7а.
2. Set the temperature of the water heater Fig. 7b
This setting allows for gradual temperature adjustment.
3. Push the knob to retract Fig. 7c
WARNING! Once a month, set the knob to ‘maximum
temperature’ for a period of 24 hours (unless the device is
constantly operated in this mode) – this ensures that no bacteria
can cultivate in the appliance.
VII. MAGNESIUM ANODE.
The magnesium anode protects the water tank‘s inner
surface from corrosion. It undergoes wear and tear and is
should be replaced periodically by the user.
Redring recommend periodic inspections of the
magnesium anode‘s condition by a qualified technician
and replacement whenever required to keep your
appliance working correctly.
VIII. PERIODIC MAINTENANCE
In hard water areas, with normal use lime scale will be
deposited upon the heating element’s surface. Over time,
this builds up and lessens the heat exchange between the
heating element and water, which could make the system
run hotter and the thermoregulator may switch on and off
more frequently.
Redring recommends preventive maintenance of your
water heater at least every every two years by a qualified
technician - protective maintenance must include
cleaning and inspection of the anode protector, replacing
it if necessary.
In order to clean the appliances use a damp cloth.
Do not clean with abrasive or solvent content
detergents.
Do not pour water over the appliance.
DISPOSAL OF THE APPLIANCE
Old electric appliances contain Precious materials and
must not be treated as domestic waste! Please dispose of
the appliance in the correct area of your local recycling
centre or similar facility.
