6.1
Preparing
Before use ensure that the temperature scales on the manifold
gauges match the refrigerants used in the system. Adjust the gauge
with the zero-adjusting screw to zero. Position of the hand may vary
and might not point to zero depending on the atmospheric
pressure.
Readjusting the gauge might therefore be necessary before each
use of the manifold. The zero adjusting screw is positioned either at
the top or through the front lens depending on the type of manifold.
6.2
Connecting the manifold to a system
Connect hose from blue valve to system suction pressure side
Connect the hose from the red valve to the high-pressure
system
Connect the hose from the middle connection to the vacuum
pump
Close Both valves (6+7)
6.3
Evacuation of a system
Switch on vacuum pump
Open both valves (6+7)
Check negative pressure on low pressure gauge
When final vacuum reached, close both valves (6+7)
Please note: The evacuation time may vary depending on the size
of the system. A minimal time span of 20 minutes must be
reserved to evacuate a small to middle sized system.
