Page 3: Receiving The Air Conditioner
RECEIVING THE AIR CONDITIONER Inspect the air conditioner. Check for concealed damage that may have occurred during shipment. Look for dents, scratches, loose assemblies, evidence of oil, etc. Damage evident upon receipt should be noted on the freight bill. Damage should be brought to the attention of the delivering carrier -- NOT to Pentair Equipment Protection -- within 15 days of delivery. -
Page 4: Technical Information
TECHNICAL INFORMATION SEQUENCE OF OPERATION The air conditioner comes standard with two internally mounted thermostats or remote access control. There are two modes of operation; heating and cooling. During heating and cooling modes the evaporator fan will be running. HEATING When the enclosure temperature is below the heating thermostat setpoint, power is applied to the heaters. -
Page 5: Phase Monitor
PHASE MONITOR This product is equipped with Phase/Voltage Protection. Please verify correct phasing and voltage before operating. Note the fans may still operate if phasing is incorrect, but the compressor will not, so the unit will not cool. Illuminated light on Phase Monitor indicates phase is correct. If the light is not illuminated, disconnect power from the unit and swap any two power leads at the terminal block. -

Page 13: Remote Access Control (Optional)
REMOTE ACCESS CONTROL (OPTIONAL) INTRODUCTION The Remote Access Control is a parametric controller for the complete management of air conditioners. All settings are pre-programmed at the factory. Cooling/heating set-points, cooling/heating differential and high /low temperature alarm set-points can be adjusted by the user. Alarms are outputted through a relay contact and also can be accessed through an Ethernet connection utilizing SNMP, EtherNet/IP and Modbus TCP. -

Page 26: Maintenance
MAINTENANCE COMPRESSOR The compressor requires no maintenance. It is hermetically sealed, properly lubricated at the factory and should provide years of satisfactory operating service. Under no circumstances should the access fitting covers be loosened, removed or tampered with. Breaking of seals on compressor access fittings during warranty period will void warranty on hermetic system. Recharging ports are provided for the ease and convenience of reputable refrigeration repair service personnel for recharging the air conditioner. -
Page 27: Condenser And Evaporator Air Movers
CONDENSER AND EVAPORATOR AIR MOVERS Impeller motors require no maintenance. All bearings, shafts, etc. are lubricated during manufacturing for the life of the motor. If one of the condenser impeller motors (ambient impellers) should fail, it is not necessary to remove the air conditioner from the cabinet or enclosure to replace the blower. -
