1) TECHNICAL AND DIMENSIONAL CHARACTERISTICS
The technical and dimensional characteristics of the appliances are given, according to the model, in Figures 6, 7, 8, 9, 10, 11, 12,
and 13, and in the Table of Dimensions, table 1. The electrical specifications are given on the appliance, according to the model.

2) GENERAL INSTRUCTIONS

Installation is the customer's responsibility. The Manufacturer declines any liability for damage due to incorrect installation or non-
compliance with the instructions contained in this user's handbook, and in particular:
the electrical connection must comply with that specified in the relevant section;
the "water safety unit" must be correctly installed, efficient and not tampered with;
installation and maintenance must be carried out by qualified personnel in compliance with current regulations;
the maintenance instructions must be respected;
the appliance must be installed in a suitable closed room (to avoid appliance freezing);
the appliance is only intended for domestic use.
This appliance complies with the current provisions of EEC Directives.
The internal boiler is designed to withstand a max. pressure of 0.8 Mpa (8 bar) without deformation.
3) INSTALLATION (by qualified personnel only)

3.1. Wall mounting

After checking that that wall is strong enough fix 2 hooks of suitable size (not supplied) to it, making sure they a securely anchored.
Then hang the appliance on the hooks by means of the support bracket (Fig. 14 and 15 ref. 13).
3.2. Anode.
The magnesium anode fitted inside the appliances, together with the special treatment inside the boiler, guarantees protection
against corrosion of the tank.

3.3. Water connection

The water inlet and outlet are marked as follows:
- blue ring for the cold water inlet;
- red ring for the hot water outlet.
It is advisable to place the appliance near the main hot water drawing point in order to avoid heat loss along the piping, and possibly
near a drain to facilitate emptying operations. The appliance water connection is shown in Fig. 3, 4 and 5. The procedure for correct
installation is illustrated below.
Dielectric nylon couplers: in order to protect the tank from electrolytic action, it is compulsory to fit the two dielectric nylon couplers
(not supplied by us) in the inlet and outlet pipes.
3.3.1. Water safety unit (compulsory).
It is compulsory to install a water safety unit (not supplied by us) conforming to current EN 1487 standards or equivalent, which
must comprise at least the following elements:
 Stopcock;
 Non-return valve;
 Non-return valve control device;
 Safety valve;
 Water pressure cutoff device.
The above-mentioned components are necessary for safe operation of the appliances supplied. The rated pressure setting of the
water safety unit must be 0.7 Mpa (7 bar). When installing the water safety unit make sure not to force or tamper with it. Water may
drip from the water safety unit discharge connection (see par. "USER INSTRUCTIONS – Dripping from water safety unit"). This
opening must be left open to the atmosphere. A downward sloping drain pipe must be arranged in a place free of condensate and
ice. To avoid overpressures make sure the piping is free of any obstructions.
3.3.2. Pressure reducer.
If the mains pressure exceeds 0.5 Mpa (5 bar) install an adequate pressure reducer (Fig. 3 and 5 ref. 4) ahead of the water safety
unit.
