SAGINAW CONTROL & ENGINEERING • A/C USER MANUAL 7. Mounting Always disconnect the power supply before opening the unit. Heat load to be dissipated from enclosure should not exceed specific cooling output of the unit at any condition. When selecting a cooling unit, always allow for a safety margin of at least 15% extra cooling output in the worst conditions. Air inlets and outlets must be completely free from obstruction. Ensure that flows of air leaving and entering the cooling unit, internal and external, are not obstructed. Cooling unit enclosure air suction hole must be installed at the highest possible point. -

Page 12: Taking Into Operation
SAGINAW CONTROL & ENGINEERING • A/C USER MANUAL 14. 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 30 minutes before being connected to the mains and taken into operation. Upon connection the internal fan will start working. If the temperature inside the enclosure is higher than the set value of the controller, both the compressor and external air fan start working. -
Page 13: Maintenance & Cleaning
During transport and storage the cooling unit must be kept in the position marked on the box and at a temperature between -40˚F and 158˚F and a relative humidity of max. 95% (at 77°F). Check that the packaging has not been damaged during transport. 18.
