5.2.3 ELECTRIC HEATER CONNECTION (MARKED "DI" IN UNIT CODE)
The unit equipped with an electric DI heater is connected to the relevant control system and further to the electrical network. The general safety
regulations for the assembly and installation of electrical equipment apply to this equipment. On the front of the unit there is a cover with a release
button for the non-automatic thermal fuse. The non-automatic thermal fuse reacts in the event of overheating of the heater's heating block
(temperature above +120 °C). The electric heater is also equipped with an operating thermostat with automatic reset (set temperature is +60 °C,
when it is exceeded, the operating thermostat opens and switches off the heater, after cooling below +60°C the heater automatically switches on
again).
Location of the release button under the cover on the
unit outer casing („xH“ and „xP“ unit positions):
Location of the release button on opening
of the unit door („xV“ unit positions):
If the electric heater emergency thermostat of the unit trips again, it is necessary to immediately look for the cause of the fault. Repeated manual
reset of the heater overheating error by a button on the heater is inadmissible and is not a solution to the fault. The reason
for this type of failure may be insufficient air flow through the electric heater of the unit, which will cause the heating rods to overheat and the
intervention of the emergency thermostat. The solution is to increase the air flow to the required minimum level according to the following table.
