3.3.1 Cathodic protection
When chloride concentration in Domestic Water is higher than 250 mg/cm 3 , it is advisable to install
a cathodic protection inside the tank to prevent premature deterioration of it. DOMUSA TEKNIK
provides as an option an electronic cathodic protection suitable for its range of tanks. For installation,
please read carefully the assembly instructions supplied with the equipment.
3.3.2 Sanit S hidraulic kit
Due to the increased temperature of the accumulated water, the pressure in the tank increases. For
the protection of the tank,
DOMUSA TEKNIK recommends placing the hydraulic kit. For installation,
please read carefully the assembly instructions supplied with it.
3.3.3 Electrical Heater
The BT TRIO tanks have two sockets (E
1
and E
2
) to connect the two electrical heaters; one for DHW
and one for the heating circuit. DOMUSA TEKNIK supplies three 1.5, 2.5 or 3.5 kW electrical heaters
as an option. For installation, please read carefully the installation instructions supplied with them.
4 TANK DRAINAGE
4.1 Primary circuit drainage
For the correct drainage of the BT DUO HE tank, it is advisable to install a cut-off valve in the buffer
inlet or in the primary inlet socket provided in the lower part of the tank.
4.2 DHW tank drainage
The DHW circuit of the tank should be depressurised before draining the tank. To perform the
drainage, remove the elliptical cover of the tank and insert a flexible hose into it.
Direct the other end of the hose to a nearby floor drain, so that the drain is at a level below the base
of the tank. Suction the water slightly with your mouth so that the water begins to flow and wait for
the tank to be empty completely.
