1. IMPORTANT INFORMATION
•Read these instructions carefully before installing or using this heater for the first time. The guarantee will not
cover damage caused by not following these instructions.
•The instructions should be retained for future reference. This guide must be kept and given to any new owner.
•This appliance is designed for domestic use only.
•The installation must be carried out by trained personnel and in accordance with the current electrical
regulations.
•This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory
or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction
concerning the use of the appliance in a safe way and understand the hazards involved. Children must not play
with the appliance. Cleaning and user maintenance must not be made by children without supervision.
•Children aged from 3 years and less than 8 years shall only switch on/off the appliance provided that it has been
placed or installed in its intended normal operating position and they have been given supervision or instruction
concerning use of the appliance in a safe way and understand the hazards involved. Children aged from 3 years
and less than 8 years shall not plug in, regulate and clean the appliance or perform user maintenance.
•Children of less than 3 years should be kept away unless continuously supervised.
•Dielectric hoses must be installed both in water inlet and water outlet. The guarantee will not cover damage
caused if dielectric hoses are not fitted.
•The use of this water heater is forbidden in areas where gases, explosive or inflammable substances are present.
•Ensure the power supply to the socket into which the appliance is plugged is in accordance with the rating label
on the heater.
•This appliance must be earthed.
•Keep the power cable away from the hot body of the electric water heater.
•Do not let the cable hang over the edge of a table or counter or let it come into contact with any hot surfaces.
•The improper handling can cause injuries.
•Do not pull on the connection cord, but rather on the plug, to separate the appliance from the mains.
•Do not use extension cable. This could overheat and cause fires.
•Never touch the appliance with wet or humid hands or barefoot.
•The water heater must be disconnected during installation and cleaning.
•The water heater should not be located in front of, or under an electrical socket.
•The water heater should be positioned so the controls cannot be used when using the shower or bath.
•The location of the water heater should not be close to curtains or other inflammable articles.
•It is important to maintain a minimum distance of 80 cm between the water heater and curtains, or any other
combustible materials.
•Never dismantle the components of the water heater or replace the components with the ones that do not
meet the safety requirements. If the supply cord is damaged, it must be replaced by the manufacturer or its
service agents or a similarly qualified person in order to avoid a hazard.
•The presences in the atmosphere of tobacco smoke or atmospheric pollution can, with time, discolour the
heater surface.
•Do not use outdoor.

2. INSTALLATION
When possible the water heater should be sited to minimize the pipe distance to hot water outlets.
It should be protected from moisture and frost.
Please note that the inlet and outlet are easily accessible. Avoid if possible the use of many fittings, so that it can be
disassembled without problems or any spare part may be easily replaced.
Wall and fixings must be suitable to support the total weight of the water heater when full.
Installation must comply with regulations for electrics if installed in bathrooms.
Use the supplied mounting bracket to fit the water heater to the wall.
Fix the bracket securely to the wall using suitable screws with appropriate plugs or fixings. Only then it is possible to hang the
water heater from the bracket.
Maintain a clearance of 20 cm underneath the water heater to allow maintenance.
This water heater is to be installed exclusively in vertical position. Inlet and outlet must be always in the lower part of the
water heater.
Water connections.
All the fittings are G1/2”.
Before making the water connections it is necessary to clean all the pipes to prevent that any debris is introduced in the
water heater.
ATTENTION. Never connect directly inlet and outlet to the existing pipes. Dielectric hoses (max. tightening torque 3.5 kgm)
must be installed both in water inlet and water outlet to prevent from corrosion. The guarantee will not cover damage
caused if dielectric hoses are not fitted.
PRESSURE REDUCING VALVE. If the incoming water pressure exceeds 5.5 bar it is necessary to install a Pressure Reducing
Valve on the water main into the dwelling. It is recommended a pressure between 3 and 4 bar.
On the cold water inlet a 7 bar pressure relief valve including a non-return feature must be installed. The warranty only
covers the appliance if this valve is installed and the installation diagram is followed at any time.

8
The Pressure Relief Valve may discharge water and it should be piped to a safe but visible drain point.
A tundish should be incorporated close to the appliance where any discharge will be visible nut not hazardous. The pipe work
should have a continuous fall to the drain and the diameter should not be lower than the hole in the Pressure Relief valve.
When the water is being heated the water expands and it is possible that some water will drip (up to 3% of the total volume
each heating cycle). It is normal.
Electrical power supply.
Never connect to the electricity supply an empty water heater.
Ensure the power supply to the socket into which the appliance is plugged is in accordance with the rating label on the
heater.
This appliance must be earthed.
All models are supplied with an electrical interrupt cut-out. This will switch off the heater if, for any reason, it overheats.
Should the cut-out operate, disconnect the water heater from the electricity supply and remove the cause for the
overheating.
Commissioning.
IMPORTANT. Never connect to the electricity supply an empty water heater.
Turn on all the hot water system taps and thoroughly flush allowing water to flow until no air is present. This will
automatically vent the integral hot water store of any air.
Check there is no leakage in the installation.

3. OPERATING THE WATER HEATER
Connect the water heater to the electrical socket. The heating indicator will be lit as long as the heating element is energized.
The light will go out when the desired temperature is reached.
The setting of the water temperature can be modified by turning the Temperature Controlling Knob up to 75ºC max.
The thermostat will maintain the water temperature as long as the water heater is connected to the electricity supply.
If there is any risk of frost conditions may be opportune to empty the water heater. It could be done by means of the
Pressure Relief Valve.
Should any continuous water steam or boiling water is delivered at draining hole or at any hot water system tap, disconnect
immediately the water heater from the electrical socket and get in contact with after sales service.
4. MAINTENANCE
IMPORTANT: Check every month that the Pressure Relief Valve is not blocked. Operate the spanner to drainage position. If
the Pressure Relief valve is obstructed it must be replaced.
Every two years it is necessary to arrange heating element de-scaling works at the same time it is necessary to check the
magnesium anode if required. The warranty will not cover any damage caused by the inobservance of this point and if the
anode is completely gone due to lack of maintenance.
Clean and dust with a dry, soft cloth only when the unit is disconnected and cold.
Do not use solvents or abrasive products for cleaning. Do not immerse the electric water heater in water.
This thermal radiator has been manufactured under an assured quality system using environment friendly processes. Please
take the heaters to a clean point once their useful life is finished, in order to recycle their materials in the right way.
