IMPORTANT
Use the certified piping that is resistant to pressure and temperature of the equipment.
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 con-
nection has a red ring.
• Under no circumstances must the relief valve be removed, nor its correct operation be can-
celed in the closed system; and 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.
CAUTION!
The electrical installation must be carried out by a CALOREX SERVICE specialized technician,
because this is a dangerous procedure.
