INSTALLATION

ACCESORIES

This electric water heater includes the basic installation elements which are found in the packaging, i.e.:

– Insulating bushing for pipes.

- Safety valve.

The accessories are located within the packaging.

WALL MOUNTING PROCEDURE

Both the wall and the screws and Rawl-plugs should be capable of withstanding the weight produced by a totally full heater. In case of low thickness walls, the wall should be reinforced.

NOTE.- The placement of the heater must allow access to the supply cable.

LOCATION

The installation procedure is greatly facilitated by being able to locate the unit horizontally or vertically anywhere in the house. It is advisable, however, to situate the unit as close as possible to where the hot water is to be used as pipe length reduction allows water temperature losses to be prevented.

A minimum 0,5 m. space should be left underneath the pipe outlet for servicing.

As shown in the Figure 1 and 2, when installed horizontally, the input and output pipes must be located on the left. Should the unit be close to a wall, leave the minimum recommended space (0,5 m.) for maintenance and servicing operations.

Don't install the heater with its wall mounts against the floor nor on a horizontal plane.

HYDRAULIC INSTALATION

NOTE FOR INSTALLERS: the insulating sleeves found inside the packaging, must be located on the inlet/outlet pipes, using teflon on the screw of the pipes. Tightening torque for sleeves: 3.5Kg/m.

Before proceeding to the hydraulic connexion, please rinse the connecting pipe in the order to avoid filth from entering inside the electric water heater.

Install the water heater according to the diagrams in figures 1 and 2.

a) The safety valve supplied with the heater MUST BE INSTALLED on the cold water input pipe.

No other hydraulic accessory can be installed between the safety valve and the cold water inlet pipe.

The outlet of the safety valve must be connected to a drain, whose diameter should be at least identical to inlet pipe. The inclination must be continuous and open, keeping a minimum distance of 20mm., as shown in Figures 1 and 2. This pipe must be installed in an environment where freeze is not possible and with a downward slope. Water expands when heated, leaking (at heats a 3% per heating cycle). Do not worry, this is a standard phenomenon.

To empty the heater, operate the safety group hoisting the lever as shown on figure 3. We should act on said lever periodically to prevent it locks and check for proper operation.

In the models with upper connections, undo the components cover and undo the drainage bolt shown in figure 4.

b) If the water-supply pressure exceeds 5 bars, a type-approved reducing valve (between 3 or 4 bars) must be installed. c) In case of plastic piping in the system, please take into account pressure and temperature conditions. Maximum pressure 9 bars and 70°C maximum temperature in standard conditions or 110°C in abnormal conditions when the safety thermostat cuts the energy supply.

ELECTRIC INSTALLATION

All storage water heaters are of 230V AC. Before connecting make sure that the mains supply and unit input features coincide.

The heater's installation procedure is totally straightforward and only requires that Low Voltage Electronic Regulations be met.

For installations in bathrooms and toilets Regulation IEC 60364-7-701 shall be adhered to.

VOLUME OF PROHIBITION: Zone 1 defined in figure 5.

No switches, sockets or lighting fixtures will be installed.

VOLUME OF PROTECTION: Zone 2 defined in figure 5.

No switches will be installed, however safety sockets or sockets protected by a 30 mA circuit breaker may be installed.

The boiler should be installed outside the VOLUME OF PROHIBITION, in order to prevent water reaching the inside of the appliance. If the boiler has no plug, electrical power should be supplied through a bipolar switch with contact openings of at least 3 mm. The installation should be protected with fuses of a calibre corresponding to the absorbed current. An earth connection should be included in every electrical installation. To make this connection, the boiler plug is provided with the appropriate contact, therefore it is enough for the base of the plug to correspond to that supplied with the appliance. If there is no regulatory “EARTH”, we recommend the installation of a ≤30 mA differential switch.

This appliance complies with the regulation on Radio-electric Disruption and interferences.

WARNING: always service the appliance with official aftersales, included the plug.

USE

START UP

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 taps and check the system for leaks.

Don't connect the heater to the power mains if uncertain as to whether it is full or not.

Electric Connection Plug into the mains and press the main power input switch. A light flashes on when the heating element is activated. The thermostat re-connects the heating element after a certain amount of water has been used.

Adjusting water temperature. Allows the user to adjust the temperature of hot water between about 30 °C (minimum position) and 70 °C (maximum position).

Position E. (Energy saving). The water reaches a temperature of about 55^ C. In this position the heat losses are minimal and the formation of limescale is virtually eliminated.

It is advisable to have the heater plugged into the mains permanently as the thermostat will only activate the unit whenever it becomes necessary to maintain the selected temperature setting. The expanded polyurethane foaming will neutralize any potential heat loss.

How to empty the unit. The heater should be fully drained if left unused for extended periods or if subject to freezing hazards where

installed. This can be done by means of the safety valve.

Always remember to:

– Cut-off the power supply.
- Shut-off the input cock.
- Open the hot water tap.

MAINTENANCE

The water heater does not need any specific maintenance. Before cleaning the device, disconnect it. Scrubbing it with a smooth cloth or moist sponge is enough. Do not use abrasive materials or detergents.

Any overheating caused by thermostat failures is offset by the safety limiting device cutting both stages off and leaving the heater without power input.

Should any problem arise, the customer is advised to contact the After Sales Services.

THE MANUFACTURER reserves the right to modify the characteristics and specifications of all products without prion notice.
