COMPACT
• Take down the control panel's front panel and correctly connect the cable between
the control panel and the electronic control.
• This will disappear when the unit is in a position of less than 45º. The electronic
control detects the indication (the unit must not operate with a slant equal to or
above 45º, in order to avoid damage in the compressor).
• Clean the run-off pipe and valve blockages (Take down the outside cover of the unit
for access).
• Replace the EPDM seal (take down the unit and thoroughly clean the surface where
the EPDM seal is to be attached).
• Seal the cable output in the blower and evaporator cabin cover (remove the unit's
outside cover for access).
• Verify the load by checking the pressure; if it is below 0.5 bars or above 5.0 bars
with the unit running, restore the load and vacuum deair the circuit for at least 30
minutes, then introduce 250 g of R134a gas (the unit has 250 g in each circuit).
• Clean the condenser with pressurised air.
• Connect or replace the condenser fan.
• Check the pressure; if it is below 0.5 bars with the unit running, clean the circuit or
replace the obstructed components (possibly the continuous flow capillary pipe).
