GENERAL The PAU air cooled single packaged air conditioners shallbe completely factory assembled, leak-tested, evacuated and fully-charged with R-410a, ready for installation. UNIT CASING The unit shall be constructed from elector galvanized steel. The exterior panels shall be acoustically lined with rubber insulation. The insulation shall be affixed to the casing with the water proof adhesive. COMPRESSOR All model shall have scroll hermetic compressor(s). All compressors are mounted on vibration isolators. EVAPORATOR COIL The direct expansion evaporator shall consist of full face coil with counterflow circuits, seamless 7 mm. OD staggered copper tubes mechanically bonded into aluminium blue fins. CONDENSER COIL Coils shall be internally enhanced, seamless copper tubes, mechanically expanded into aluminium blue fins with full height collars. Coil shall be leak tested at 600 PSIG from factory. EVAPORATOR BLOWER The evaporator blower shall be the double inlet, forward curved centrifugal type and statically and dynamically balanced. CONDENSER FAN AND MOTOR Fan shall be dynamically and statically balanced, direct drive, providing vertical air discharge from extended orifices for efficiency and low noise. direct drive UNIT CONTROL Each system shall contain factory mounted wired and tested controls required to operate and protect the unit. The control system shall include compressor overload protection, motor winding protection, high and low pressure cutouts to guard against compressor damage due to high discharge head pressure and system leakage. REFRIGERANT CIRCUIT The refrigerant circuit shall be factory piped, leak tested and fully charged with R-410a. Each refrigerant circuit shall consist of a compressor, expension valve and service valve.
