NOTE, In case the temperature sensor of the condenser detects 70ac
' in the
cooled air model or
62º Cin the water cooled version for one of these
reasons:
- DIRTLY CONDENSER (cooled by air)
- INADEQUATE CONDENSATION WATER (cooled by water)
- BURNT FAN OR STOPPED (cooled by air)
- HIGH ROOM TEMPERATURE (UP TO
43°
C)
the unit stop inmediately so as to prevent to be working in extremely
abnormal and dangerous situation. When this happens it switch on the RED
LIGHT,that warn of high temperature.
After eliminating the cause of excessive temperature in the condenser,
push button RE-SET.
The RED LIGHT will flash and after 3 minutes the unit will start working. The
temperature sensor of the condenser has also another option for security, it
consist in preventing the start up of the unit if the room temperature (detected
by the sensor of the condenser) in where it is installed the unit is less than
10
C.
When the room temperature is up to 10º
C,
the electronic board start up
again the unit automatically after 3 minutes.
The pressure of air intake or low pressure in normal conditions is of 0.5 bar in
model MF 22 and 2.4+2.6 bar in model MF 31, MF 41, MF 51 Y MF 61 after
some minutes of operation. These valuer can change between 0.1 bar or 1.2
bar, in relation with the water temperature that supply the evaporator.
NOTE If after 10 minutes of operation not produce ice and the tempertaure
registered by the sensors of the evaporator do not reach
-1 C, the unit stops
and switch on flashing the 5
