installation
This heater must be installed according to the following indications regarding the
presence of:
Humidity: do not install the appliance in humid environments (without ventilation).
-
Ice: do not install the appliance in environments with a probability of temperatures
-
dropping to critical levels with a risk of ice formation.
Sun rays: do not expose the appliance directly to solar rays, even in the presence of
-
windows.
Dust/fumes/gases: do not install the appliance in notably aggressive environments,
-
such as those with acid fumes, dusts, or saturated gas.
Electric shock: do not install the appliance directly on power lines that are not protected
-
from voltage fluctuations.
V.- HYDRAULIC INSTALLATION
To achieve a good heater installation, verify the type of water feed system you have at your
home, there are two di erent types.
Open System (with a cistern): to supply water to the heater, an air tube must be installed at
the cold-water inlet.
•
The air tube installation must not be omitted for the cold-water inlet, and we recommend
installing one for the hot water outlet also.
•
The air tube discharge must be slightly higher than the upper level of the cistern,
by at least 20 cm. See Fig. 4.
•
Long segments of piping should be avoided and/or accessories such as elbows,
T connections, distributing valves, etc. (The recommended distance between the heater
and the point of use should not exceed 10 m).
•
To have the correct hot water pressure, the cistern must be at least 2 m above the
shower level.
