INSTALLATION
This electric unvented storage water heater includes the basic
installation elements which are found in the packaging, i.e.:
- Insulating bushing for pipes.
- Safety valve.
Installation and ļ¬rst operation of the storage heater and the
ļ¬ttings have to be done by an expert which can take the
responsibility for properly done work and explains the handling
procedures.
For the connection the speciļ¬c technical conditions of the
energy supplier as well as the valid standards and safety
regulations have to be considered.
WALL MOUNTING PROCEDURE
Use 4 adequately resistant and sturdy screws and rawl-
plugs capable of holding the weight of the ļ¬lled heater.
LOCATION
The installation procedure is greatly facilitated by the possibility
to locate the unit horizontally (EWH-SL/SLN and EWH-R/RN)
or vertically in a frost-free (!) place anywhere the house.
It would be a good idea to place the unit as close as possible
to the outlet - short piping means little loss of temperature.
A minimum space of 50 cm below the outlet pipe is necessary
for servicing.
As shown in the drawing the input and output pipes must be
on the left side when the heater is installed horizontally.
Should the unit be close to a wall leave the recommended
minimum-space for maintenance and service.
Do not install the heater with its wall mounts against the ļ¬‚oor
nor on a horizontal plane.
HYDRAULIC INSTALLATION
The heater must be connected to the water supply mains.
a) The safety valve - supplied with the heater- MUST be
installed on the cold water input (see right side)
- Before connecting the safety valve with the heater, the
connecting pipe must be rinsed carefully.
- The draining pipe and the safety valve must be left open
to the air and be installed in a continuous downward slope.
Water expands when heated. The units of the series R,
eco R and SL are supplied with a safety valve that lets the
expanding water ļ¬‚ow back into the cold-water feed.
The units of the series RN and SLN have a safety valve
that prevents the expanding water (N=non return) from
flowing back into the cold-water feed. Here a suitable siphon
for the absorption of the expanding water is to install.
The drain of the safety valve must not be blocked.
To open the safety valve (not safety valve eco) to let the
water ļ¬‚ow from the heater - via the outlet - turn the knob
clockwise or counterclockwise as you please.
The proper operating of the safety valve should be tested
periodically that way:
- turn the knob clockwise or counterclockwise up to the top
position
- the water should ļ¬‚ow out of the passage
- turn the knob to its down position
The pressure rating is indicated on the knob.
b) If the water-supply pressure exceeds 5 bar, a type-approved
reducing valve must be installed.
ELECTRIC INSTALLATION
All storage water heaters of the EWH-series are of 220/230 V
single phase design. Before connecting make sure that the
mains supply and unit input features coincide.
The heaters installation procedure is totally straightforward
and only requires that Low Voltage Electronic Regulations are
met. Although well known by the installers we would like to
point out some of the basics:
ā€œThe following volumes and provisions shall be taken into
account for installations in bathrooms or toiletsā€.
PROHIBITED VOLUME.- It is the volume limited by the
tangential and vertical planes with respect to the outer edges
of bathtub, toilet pan or shower enclosure and by a plane
situated 2,25 m above the same or the ļ¬‚oor, should the units
be embedded in the same.
Safety valve Safety valve ECO Safety valve
PROTECTION VOLUME.- It is the volume situated within the
horizontal planes previously stated for the prohibited volume
plus another two vertical ones 1,00 meters away from those
of the said volume.
No switches, power sockets or lighting equipment must be
installed within the PROHIBITED volume.
Do not install switches within the PROTECTION volume; this
does not apply, however, to safety power sockets.
If possible the heater must be installed outside the PROHIBITED
VOLUME so as to prevent water splashing against the unit.
Power must be supplied via a multi-polar switch, circuit breaker
or contactor. Adequate power rating fuses shall be made
available for unit protection purposes.
All electrical installations shall incorporate an earthing
connection. The plug used by the heater already has this
connection and only has to be inserted in a mains socket of
the same features.
Make sure the household or place of installation does have
an earth line. If not available, a diļ¬€erential switch is
recommendable.
The electric connection must be made with a power cable Type
H05VVF 3x1,5 (Serie eco-R/RN).
MAINTENANCE
The heater does not require a special maintenance procedure.
Clean by wiping with a soft cloth or damp sponge. Never use
abrasives nor detergents.
The customer is advised to contact the AFTER SALES
SERVICE to check the magnesium bar once the guarantee
has expired. Although this particular operation is not covered
by the guarantee, as it does not imply Ā«unit servicingĀ», it does
allow the wear rate of the bar to be monitored and to establish
how soon it should be changed. Moreover, indeļ¬nite heater
duration can be guaranteed.
Any overheating caused by thermostat failures is offset by the
safety limiting device cutting both stages oļ¬€ and leaving the
heater without power input.
If this happens, contact our After Sales Service.
WARNING.- Never remove the lead cover without previously
disconnecting the heater from the power supply.
THE MANUFACTURER reserves the right to modify the
characteristics and speciļ¬cations of all products wilhout prior
notice.
OPERATION
Filling up. Open the shutoļ¬€ cock as soon as the heater has
been installed. Open the hot water taps. Water appears as
soon as the unit ļ¬lls up completely. Close the laps and check
the system for leaks. Do not connect the heater to the power
mains if uncertain as to whether it is foll or not.
Electric connection. Plug into the mains and press the main
power input switch. A light ļ¬‚ashes when the heating element
is activated (on some models). The thermostat re-connects
the heating element after a certain amount of water has been
used.
Setting water temperatures. In the case of top-range models,
the external control knob allows water temperature adjustments
between 30 C (min. setting) and 70 C (max. setling).Ā° Ā°
E Position. (Energy saving) the water reaches a temperature
of approx. 55 C thus allowing the heater to operate economically.Ā°
Heat losses are minimal and calcareous deposits are practically
fully eliminated.
Heating element power setting switch. The deluxe and super
deluxe models incorporate double power rating features and
a switch for power setting changes:
Pos. II; ; MAX.: Total power
Pos. I; ; MIN.: Minimum power
It is advisable to have the heater plugged into the mains
permanently as the thermostat will only activate the unit when
it becomes necessary to maintain the selected temperature
settings.
How to empty the unit. The heater should be fully drained if
left unused for extended periods of time or if subject to freezing
hazards where installed. This can be done by means of the
safety valve (not safety valve eco). Always remember:
- Cut-oļ¬€ the power supply
- Shut-oļ¬€ the inqut cock
- Open the hot water tap.
