- Page 3 The refrigeration unit is protected against overpressure and compressor overload. with insufficient ventilation of the condenser (e.g. dirt deposits) the equipment is switched off. This cooling process is a self-refrigerating cascade type. A mixture of non-flammable and safe refrigerants is compressed and circulated by a compressor.
- Page 4 In this unit, there is a series of intermediate special heat exchangers (cascade condensers) between the air-cooled condenser and the final cooling coil (cold probe). There are several stages of partial condensation, phase separation, condensate throttling, and intermediate cooling. In addition, the system has a suction-side refrigerant vapor expansion tank and a discharge-side buffer tank to limit start-up discharge pressures.

It is advisable to set up the equipment so that the control unit is towards the front and that the ventilation for the refrigeration unit, especially on equipment with air-cooled condenser, (ventilation grille in lower part) is not impeded.

- Page 7 value first, and then start auto-tuning. Generally, for application with heating time of 10%～80% can obtain satisfying auto-tuning result. If the heating time is not in the range of 10～80%, the auto-tuning will run for a long time and can’t get satisfying result. Raising setpoint for heating time less than 10% or decreasing setpoint for heating time greater than 80% can improve auto-tuning result.
