WATER 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. 3).
•
Long segments of piping and/or accessories such as: elbows, T connections, distributing valves, etc.,
should be avoided (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.
IMPORTANT: in the Open System, DO NOT INSTALL the included relief valve, because it
could cause a loss of line pressure.
Closed or Pressurized System (direct from the water system): regarding the heater's water supply, we
recommend installing a relief valve (INCLUDED) at the hot water outlet, calibrated at (0.68 MPa)
) (100 psi) (see Fig. 3).
(7 kg/cm

IMPORTANT: when there is excessive pressure, water exits through the relief valve. This is a
normal mechanism and does not mean the heater has malfunctioned. Avoid undue water spills by
installing a drainage tube at the relief valve exit towards the drains.
Maximum operating pressure of 7,13 kg /cm (0,7 MPa)
We recommend checking the relief valve (included) at least once a year to make sure it is in good working
condition.
