Closed System Installation Diagram
FIG. 5
Closed System
Never connect this outlet
to your plumbing system
Hot water outlet
IMPORTANT:
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.
•
To fill the heater, open the supply valve on the cold-water supply pipe. Open a hot
water tap slowly (preferably the shower) to allow air to exit the heater and the pipe.
A continuous water flow at the hot water tap indicates that the heater is full of water.
