3. INSTALLATION REQUIREMENTS
The unit must be installed and set up by a qualified technician in accordance with the rules laid down
by local health and safety regulations, such as the "Low voltage Electro-Technical Regulations", the
Technical Building Code and relevant local regulations.
The unit heats water to a temperature below boiling point. It must be connected to a main water supply that is
compatible with the unit's performance levels and capacity.
Before connecting the water heater, the following steps must be carried out:
- Check that the characteristics (see data plate) meet the customer's requirements.
- Read the instructions on the packaging label and on the unit's data plate.
Installing the water heater
This unit has been designed to be installed inside buildings only, in accordance with current regulations. Fur-
thermore, installers are asked to follow these recommendations in the presence of:
-
Humidity:
Do not install the unit in closed (unventilated) or damp/humid spaces.
-
Freezing conditions:
Do not install the unit in areas where the air temperature may drop to critical levels
and there is a risk of freezing conditions.
-
Sunlight:
Do not expose the unit to direct sunlight, even if there are windows.
-
Dust/vapours/gas:
Do not install the unit if particularly hazardous substances are present, such as vapours,
dust, or gas saturates.
-
Electrical discharges:
Do not install the unit directly connected to electrical power sources that are not
protected against surges.
Location for installing the unit
It is convenient to install the heater as close as possible to the water mains supply to minimize heat loss from
the pipes. TL plus water heaters are always installed with downstream water connections. To facilitate inspec-
tions and internal cleaning, a free space must be left of at least 25 cm between the protective cover (pos.1,
page 40) of the heater and any fixed obstacle.
WALL-MOUNTED FITTING
In the case of brick or cavity block walls, partition walls with limited static or any kind of brickwork other than
those mentioned, a preliminary inspection must first be conducted of the system to be used to mount the unit.
Installation Procedure:
1. Ensure that the surface of the area where you are going to mount the heater can support four times the
weight of the heater when filled with water.
2. Use a power drill to make the holes to a depth of at least 90 mm in the wall. These holes must be level on
the same line.
3. Insert two wall plugs in the hole, screw in the screw hooks and place them facing upwards, then raise the
electric heater and aim for the hooks, fasten it firmly into position and check the wall plugs are not loose
to ensure that the electric heater is firmly mounted.
