R717 charge
It is very important that the chiller has the correct charge. The P&I diagram states the charge for
each specific chiller.
At normal operation the suction superheat should be between 0.5-3°K.
In the evaporator, droplets should come out of the top of the plates. The plates must not be com-
pletely covered by liquid.
Note: The liquid level must never be visible in the inspection glass.
The quality of the refrigerant must be appropriate for refrigeration applications; for details, see:
TI2015-01 Ammonia quality.
