Connecting the manifold to a system
Connect blue hose (1) » compound side of system•
Connect red hose (2) » pressure side of system•
Connect yellow hose (5) » vacuum pump•
Close both valves (3+4) •
Evacuation
Choose vacuum mode on digital manifold•
Switch on the vacuum pump•
Open both valves (3+4)•
Check pressure on vacuum display•
When the expected vacuum is reached close both valves (3+4)•
Please note:
The evacuation time may vary depending on the size of a system. A minimal time of 20 minutes must
be observed to evacuate a small to middle sized system.
Charging a system after evacuation
Keep all valves closed (3+4).•
Disconnect the yellow hose from the vacuum pump and connect this hose to the refrigerant gas cylinder.•
Open valve from refrigerant gas cylinder.•
Open blue valve (compound side). The system is now being charged with refrigerant. Check the correct quantity •
of refrigerant with a charging scale (REF-METER from REFCO) and observe the pressure on the compound side.
When the correct filling quantity has been reached close all valves.•
After the charging process check the pressure on the high pressure and compound side of the unit.•
Disconnect all hoses from the system.•
Open valves (3+4). •
Measuring by using the Superheat-Subcool function
See “connecting the manifold to a system.”•
Plug in the external temperature sensor (6) into the DIGIMON. (Jack on the left hand side of the shell.)•
Install temperature probe of the external sensor (6) on the liquid or suction line.•
Choose the applicable refrigerant. (See “Selection of the refrigerant.”)•
Activating display of temperature difference: Press • SUPERHEAT/SUBCOOL .
Switch between superheat/subcool (liquid/suction line): Hold • ENTER and press SUPERHEAT/SUBCOOL.
