5. Taking into operation
Attention
The unit can be damaged by lack of lubricant.
To ensure that the compressor is adequately lubricated the oil, which has been
displaced during transport, must be allowed to flow back into it. The unit must
therefore be allowed to stand for at least 10 mins. after mounting before being
connected to the mains and taken into operation.
The unit is controlled in relation to the cabinet internal temperature. A temperature sensor
continuously measures the temperature of the air which is drawn into the unit from the cabinet. The
required cabinet temperature for cooling operation can be set on the cabinet temperature using the
software interface. When the cabinet temperature exceeds the set point the unit will enter cooling
operation. The compressor speed is varied according to the reading taken by the sensor in such a
way to operate in the most efficient manner and to reduce the switching on and off of the compressor.
This helps to keep the temperature inside the control cabinet as constant as possible in order to
reduce temperature induced stress on the components and fluctuating temperatures. The speeds of
the ambient and internal fans are regulated for optimal performance of the unit.
When the test button is pressed the compressor and the ambient fan will run for 180 sec. regardless of
the cabinet temp. If the test button is pressed during the 180 sec. test-run, the unit will return to its
normal operational mode.
Condensation formed inside the unit is drained from the bottom of the unit.
