Adding refrigerant!

If the refrigerant quantity is insufficient, refrigerant should be
added.
In normal operating conditions and tempered chambers, the low
pressure should be around 1.0-2.5 bars and the high pressure
should not exceed 21 bars.
Insufficient refrigerant is established by checking the sight
glasses of the liquid for bubbles .
If you are not sure about presence of liquid in the glasses, you
can stop the chamber while the compressor is operating and see
whether there are bubbles on the sight glass.
a) Connect the service hose to the liquid port of refrigerant
bottle and the low pressure service port (SP1) of the KV1 valve at
the valves panel.
