Chapter Four: Testing and operation
(1) Once the installation has been completed and checked turn on power and water supplies carry out the
following test.
(2) On the control panel press the
“
”
key, (the key has a time-lapse function, press it for 1 second),
the time and temp windows display the data.
(3) The water inlet valve turns on & water enters the boiler, the indicator LED is red. When the water
level rises to the low water sensor level the elements switch on and the heating indicator LED is on, several
seconds later when the high water sensor is reached the water inlet indicator LED changes to green and the
water inlet valve will turn off.
(4) After a few minutes of operation it will begin steaming, for small steam generator 2-3 minutes, for
larger generators 3-5 minutes.
(5) Press the
“
”
key again the controller turns off, there will be no data on display and the generator
will stop - no more steam.
(6) Press the
“
”
key once more (temp and time display again) after a few seconds the generator will
begin steaming again, let the generator operate for a short while - the water level will fall to the low water
level, check that the water inlet valve opens automatically (the water inlet indicator LED becomes red)
During the cold water enters boiler , the steam generator still produce steam once the high water level is
reached again the water inlet valve will close the and the LED will go back to green .
(7) The time display counts down to show the remaining time, when it reaches 0 the steam generator will
stop heating.
(8) Once the steam generator has operated for 10 minutes or more when it is turned off (manually or
automatically) it will enter the automatic drain down cycle; this means once the temperature of the water in
the boiler falls below 80
℃
it will and drain and then flush before it can start steaming again.
Note when the steam generator is off you can drain it manually (flush boiler and drain) by pressing the
“
drain
”
button

(10)When the preset temperature for the steam room is reached 2 of the 3 element banks will switch off
allowing just the 1 bank to continue heating to maintain the temperature. Elements will cycle on and off to
maintain the temperature to within approximately 2.5 degrees above or below the preset requirement.
(11) Boil dry protection
–
if the water supply fails the water level indicator LED will change to red and
the steam generator will stop.
(12)The
“
”
can output AC230V to power the transformer for a 12V for steam room lamp.
(13)
“
