FIG. 4
IMPORTANT:
long as the appliances are installed correctly. We can guarantee the e ciency of your equipment when using
connections designed for this purpose and that have been installed correctly, however, WE ARE NOT
RESPONSIBLE FOR THE QUALITY OF THE COMPONENTS USED, NOR THE QUALITY OF THEIR
INSTALLATION. It's recommended to use certified materials, designed and endorsed for this type of
installation according to the characteristics and required temperatures. During the heating phase, the device
normally drips water. If you wish to avoid this drip, an expansion vessel should be installed at the outlet
installation. If an expansion vessel is installed, NEVER obstruct the tank evacuation outlet, as doing so will void
the warranty.
Important points for the installation:
• Not using a well calibrated relief valve or an air tube could result in excess water pressure
in the system, which could damage the water installation and the heater.
• The cold-water inlet connection is indicated with a blue ring, and the hot water outlet
connection has a red ring.
• The relief valve must not be removed for any reason, nor its correct operation must not
be canceled in the Closed System; the air tube installation must not be omitted at the hot
water outlet in the Open System. Otherwise, an excessive water pressure increase could
damage the installations or deform the heater tank. This damage is considered out of
warranty and invalidates it, being an outside cause.
