(1) Upper camber
(2) Hot water exit pipe. Hot water exit pipes of different dimensions can be used according to the
model. Hot water is always extracted from the top portion of the tank.
(3) Lower camber
(4) Boiler flash
(5) Cold water Inlet pipe
(6) Entrance diffuser. Prevents turbulence and enables cold water entry from the lower part of the
tank.

2.2 EXTERNAL BODY

Thermosiphon external body is manufactured from sheet with cataphoresis electrostatic paint.

2.3 INSULATION

Pressurized polyurethane foam is filled between the boiler and the external body with the most
suitable density for heat insulation.

2.4 RESISTANCE

The external part of the resistance is manufactured of stainless steel, and the inner part is made of
resistance wire and magnesium oxide. Resistance flange contains the resistance, thermocouple pipe
and anode rod mounting bracket. It can be in different shapes and strengths according to model. The
mechanical thermostat, electronic thermostat and limit thermostat thermocouples attached into the
thermocouple pipe must be fitted to the deepest part of the pipe and a rubber cap should be fitted to
the end to prevent them from falling out.

2.5 FLANGE GASKET
The leak proofness and electrical insulation between tank flange and the heating element flange is
achieved by a gasket. Gasket must be replaced in situations where the flange is removed, i.e. after
cleaning the boiler scale of the thermostat.

2.6 THERMOSTAT

Mechanical thermostat is used to adjust the water temperature at the desired level. Thermostat is
mounted on the front indicator panel. The capillary tube thermocouple is placed into the steel pipe on
the resistance flange so that the thermostat can sense the water temperature. Thermocouple must be
placed into the steel tube so that it will touch the deep end. The indicator lights red while the water is
heated to the temperature that the thermostat is set. Indicator lights green when the water reaches the
desired temperature.
