Heating Resistances
Each heater has four 1500 W elements connected in parallel, which give the system a total
power of 6000 W. If under normal conditions of ambient temperature, it is not possible to reach
the temperature required in two or three minutes, it is possible that one or several heating
elements are not working.
To check the state of the element, proceed as follows:
With the main switch off check with a tester that reading the total value of the heater resistance
is indicated in the table according to the power, voltage and number for each installed heater
elements, a higher value would indicate that one or more elements are faulty .
Disconnect them and check that the individual value of each element is as shown in the table
according to the installed power and voltage.

Under extreme environmental conditions, the heater might be affected and fail to reach the
required temperature. In this case, put the unit in a more favorable place, or use an auxiliary
heating system.

Automatic Switch
This protects the elements against any possible change in voltage. With the general switch
turned off, open the control panel and make sure the switch is activated (see electrical
diagram), otherwise activate it.
