Failures

The screen includes a number of failures like indicated on this page. When
service is necessary, also a message will appear. During dry- running of the
water tank, the burner will first turn off, afterwards the machine will shut down ->
cooling down process.
Pay attention: this screen always appear if there will be switched
from position 0 to 1 (via key contact) when the required service
period is necessary. Move the control stick to the left to remove the
message from the display.

PUMPS HT

There must be present a pre - pressure (pump) at
HT pumps (pumps with high temperature).
The pre - pressure (pump) must provide for sufficient flow of water to feed the
high pressure pump and to occur cavitation. Cavitation is the phenomenon
that in a moving fluid the local pressure is going to be lower than the vapour
pressure of the fluid. Because of this mist bells will arise who can implode with
high power in the pump and could cause damages. For all these applications at
high temperature, it is ABSOLUTELY ESSENTIAL to feed the pump with positive
pressure (at least 3 bar) and with a sufficient quantity of water.
