5. STRUCTURE OF WATER HEATER
5.1
Main elements: inner tank, heating element, thermal insulation of polyurethane foam, temperature
controller, thermostat, control panel, safety valve, magnesium anode road.
5.2. Inner tank
is made of high quality steel with enamel coating, that provides high corrosion
resistance and, therefore, long service life.
-
5.3.
The following parts are installed in the water heater:
A) model WH
–
tubular electric heater, magnesium anode, capillary protective thermostat, he
at
regulator and switch;
B) model TT WH
–
tubular electric heater, magnesium anode, tubular thermostat
.
5.3.1.
Heating element
serves for water heating, and heat regulator allows to adjust the temperature
to 77 °C. Temperature regulation is provided with regulator knob located on the control panel of water
heater.
5.3.2. Magnesium anode
The magnesium anode rod is an integral part of the protection system of water tank against corrosion.
It’s necessary to check the condition of the magnesium anode rod ANNUALLY.
In case of severe wear,
the magnesium anode rod must be replaced.
The magnesium anode rod should be replaced at least
once in 24 months.
The magnesium anode rod is a consumable item that cannot be replaced
under warranty.
5.5.1.
Safety valve which is installed at the inlet of the water heater and serves to prevent the return
of water to the water
line and protect the tank from excessive pressure
.
The safety valve (pressure safety device) must be inspected regularly to check that it is not blocked
or damaged. Replace the valve or remove limescale deposits if necessary. If the safety valve is
equipped with a lever, regular valve correct operation check procedure can be performed with its help.
The drain connection, connected to the valve outlet,
