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 ﬁrst operation of the storage heater and the

ﬁttings 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 speciﬁc 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 ﬁlled 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 ﬂoor

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 ﬂow 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 ﬂow 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 ﬂow 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:

“The following volumes and provisions shall be taken into

account for installations in bathrooms or toilets”.

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 ﬂoor, 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 diﬀerential 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 «unit servicing», it does

allow the wear rate of the bar to be monitored and to establish

how soon it should be changed. Moreover, indeﬁnite heater

duration can be guaranteed.

Any overheating caused by thermostat failures is offset by the

safety limiting device cutting both stages oﬀ 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 speciﬁcations of all products wilhout prior

notice.

OPERATION

Filling up. Open the shutoﬀ cock as soon as the heater has

been installed. Open the hot water taps. Water appears as

soon as the unit ﬁlls 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 ﬂashes 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).° °

E Position. (Energy saving) the water reaches a temperature

of approx. 55 C thus allowing the heater to operate economically.°

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-oﬀ the power supply

- Shut-oﬀ the inqut cock

- Open the hot water tap.
