V.- HYDRAULIC INSTALLATION
The system shall be installed so that the control for adjusting the temperature of the water
in normal use, installed at the outlet of each shower, has priority over any other control for
adjusting the temperature of the water in normal use at any other outlet.
To achieve a good heater installation, verify the type of water feed system you have at your
Open System (with a water storage tank): 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 venting must be slightly higher than the upper level of the water storage
tank, by at least 20 cm (see Fig. 5).
•
Long segments of piping should be avoided and/or a lot of accessories such as: elbows,
T connections, bypass valves, etc. (The recommended distance between the heater
and the point of use should not exceed 5 m).
•
Check that the minimum flow of your shower is of 2,1 L/min.
•
Check that the minimum pressure of your installation is 0,2 kg/cm
4 kW V2 and 9,5 kW V2) and 0,25 kg/cm
IMPORTANT
In the open system, UNINSTALL the included relief valve, because it could cause a loss of
pressure in the line.
Closed or Pressurized System (direct from the water mains): Regarding the heater's water
supply, we recommend installing a relief valve (NOT INCLUDED) at the hot water outlet,
calibrated at (0,73 MPa) (7,5 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 a failure. Avoid undue water spills by
installing a drain tube at the relief valve exit towards the drainage.
NOT installing the relief valve in a Closed System will void the warranty. Do not skip this
step.
