3. If superheat is within the range (see charging table below), there is no need to add/remove refrigerant.
• If superheat is lower than minimum, it means that liquid refrigerant may be returning to compressor. It is
necessary to remove refrigerant or check EEV settings.
• If superheat is higher than maximum, it means that refrigeration capability of evaporator is not fully maximised. It
is necessary to add refrigerant charge or check EEV settings.
Allow the systems to stabilise (15-30 mins) and repeat the step 1-3 until superheat falls within the range specified in the
table below.
