WARNING!
At the cycle start, the unit will check the available volume inside the bottle. In case the total weight on the
scale is lower than 10.000 kg, COOLIUS-HP unit will display the following alarm signal: “Check bottle
weight”. It is indeed necessary to have at least 10.000 kg of refrigerant inside the bottle to perform this
function.

Checking the A/C system operating pressures
1.
Make sure that the 82 and 83 valves are closed and that the 87 switch is on position 0
2.
Connect the 91 hose to the A/C system low pressure side
3.
Connect the 92 hose to the A/C system high pressure side
4.
Start the compressor of the A/C system
5.
Read the pressure and its corresponding evaporation temperature on the 84 pressure gauge
6.
Read the pressure and its corresponding condensing temperature on the 85 pressure gauge
7.
Compare the values with the ones suggested by the cooling system manufacturer
4.7
Disconnecting the unit from the A/C system
At the end of the charging function or at the end of the checking of the operating pressures, some
liquid refrigerant is still inside the hoses. In order to minimize the residual quantity of refrigerant inside
the hoses, follow the below procedure:
1.
Close the hand-wheel of the quick coupler ref. 55 (red) and disconnect the 92 hose from the A/C
system while the A/C system compressor is running
2.
Make sure that the 91 hose is connected to the A/C system
3.
Open the 82 and 83 valves in order to have all the liquid refrigerant sucked by the A/C system
4.
As soon as the pressures on the high and low pressure gauges are the same and do not exceed 2÷3
bar, close the hand-wheel of the quick coupler ref. 56 (blue) and disconnect the 91 hose from the A/C
system
5.
Perform a recovery cycle to suck the remaining refrigerant from the hoses so that the unit is
immediately ready for the next operation
6.
Turn the unit off (87 switch in position 0)
7.
Close the 82 and 83 valves
8.
Carefully screw the protective caps on the A/C system service valves
9.
Using a leak detector, check the A/C system for leaks
WARNING!
The introduction of tracer additives and the following use of a UV leak detector will make it easier to
locate the point of the possible leak in the future
4.8
Setting Menu
If you press the
key in the standby screen, you can gain access to the setting menu of the unit.
