[. . . ] 20 mm air inlet Cold water 5 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. [. . . ] b) If the water-supply pressure exceeds 5 bar, a type-approved reducing valve must be installed.

Earthed plastic sleeves (supplied with the heater) 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. 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. The electric connection must be made with a power cable Type H05VVF 3x1, 5 (Serie eco-R/RN). OPERATION Filling up. Do not connect the heater to the power mains if uncertain as to whether it is foll or not. A light flashes when the heating element is activated (on some models).

Any overheating caused by thermostat failures is offset by the safety limiting device cutting both stages off and leaving the heater without power input. WARNING. - Never remove the lead cover without previously disconnecting the heater from the power supply.
