BSAGINAW CONTROL & ENGINEERING • A/C USER MANUAL 4 4. Functional Principle The unit functions on the principle of the compression refrigerator. The main components are: refrigerant compressor, condenser, choke and evaporator. These four components of the refrigerant plant are connected with each other by pipes to form a hermetically sealed system in which the refrigerant (R134a) circulates. 1. Air Intake, Cabinet Side 2.

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.

BSAGINAW CONTROL & ENGINEERING • A/C USER MANUAL 9 11. Electrical Connection The cooling unit is used where heat needs to be dissipated from electrical control cabinets or similar enclosures in order to protect heat sensitive components. The unit has two completely separate air circuits which ensure that the clean cabinet air does not come into contact with the ambient air which may well be dirty or polluted.

Press “PRG” button for 5 seconds to reach the modifiable parameter list. 2. Use ▲ or ▼ to reach the desired parameter: • C18 for temperature unit of measure • °C = 0 • °F = 1 • P25 for low temperature alarm threshold (default -10°C / +14°F) • P26 for high temperature alarm threshold (default +55°C / +131°F) 3.

BSAGINAW CONTROL & ENGINEERING • A/C USER MANUAL 12 Alarm Relay Function Both normally closed (NC) and normally open (NO) alarm contacts are provided. These refer to the alarm state. Under normal conditions, the NC contact is closed and the NO contact is open. When an alarm condition is present or the door contact is open, the NC contact will open and the NO contact will close. System power failure will give an alarm condition.

BSAGINAW CONTROL & ENGINEERING • A/C USER MANUAL 15 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.

BSAGINAW CONTROL & ENGINEERING • A/C USER MANUAL 16 16. Maintenance & Cleaning Always switch power supply off before starting any maintenance on the unit. Any repairs that may be needed must only be done by qualified personnel. The cooling unit is a low maintenance type and for most environments, no filter is required. If an air filter is installed, check it periodically for dirt and clogs. Clean or replace filter when necessary.
