To replace the belt: To align fan and motor pulleys: 1. Use a belt with same section type or similar size. Do not substitute a “FHP” type belt. When installing the new belt, do not use a tool (screwdriver or pry-- bar) to force the belt over the pulley flanges, this will stress the belt and cause a reduction in belt life. 2. Loosen the motor mounting plate front bolts and rear bolts. 3.
Changing the Fan Wheel Speed by Changing Pulleys TUBES 580J The horsepower rating of the belt is primarily dictated by the pitch diameter of the smaller pulley in the drive system (typically the motor pulley in these units). Do not install a replacement motor pulley with a smaller pitch diameter than provided on the original factory pulley.

PRE--START--UP 580J ! ! WARNING PERSONAL INJURY AND ENVIRONMENTAL HAZARD Failure to follow this warning could result in personal injury or death. Relieve pressure and recover all refrigerant before system repair or final unit disposal. Wear safety glasses and gloves when handling refrigerants. Keep torches and other ignition sources away from refrigerants and oils. PERSONAL INJURY HAZARD Failure to follow this warning could result in personal injury or death. 1.
WARNING UNIT OPERATION AND SAFETY HAZARD Failure to follow this warning could result in personal injury or death. Disconnect gas piping from unit when leak testing at pressure greater than 1/2 psig. Pressures greater than 1/2 psig will cause gas valve damage resulting in hazardous condition. If gas valve is subjected to pressure greater than 1/2 psig, it must be replaced before use.
NOTE: The default value for the evaporator-- fan motor on/off delay is 45 seconds. The Integrated Gas Unit Controller (IGC) modifies this value when abnormal limit switch cycles occur. Based upon unit operating conditions, the on delay can be reduced to 0 seconds and the off delay can be extended to 180 seconds.
Number of Compressor Stages This refers to the number of mechanical cooling stages available on a specific unit. Set this point to “One Stage” if there is one compressor in the specific unit, set to “Two Stage” if there are two compressors in the unit, and set to “None” if economizer cooling ONLY is desired.
580J Input 5 This input is a discrete input and can be configured to be one of five different inputs: No Function, Fire Shutdown, Fan Status, Filter Status, or Remote Occupancy. This input can also be configured to be either Normally Open (N/O) or Normally Closed (N/C). Input 5 is factory wired to pin J1-- 10. Field accessories get wired to its parallel pin J5-- 3. Do not connect inputs to both locations, one function per input.
Max Differential CO2 Setpt If the difference between indoor an outdoor air quality becomes greater then this value the damper position will stay at the IAQ Greatest Min Dmpr Pos. configuration point Factory Default = 650 PPM Range = 300-- 950 PPM IAQ Greatest Min Dmpr Pos. This is the greatest minimum position the economizer will open to while trying to control the indoor air quality, CO2 differential.
When free cooling is available as determined by the appropriate changeover command (dry bulb, outdoor enthalpy, differential dry bulb or differential enthalpy), a call for cooling (Y1 closes at the thermostat) will cause the economizer control to modulate the dampers open and closed to maintain the unit supply air temperature at 50 to 55_F. Compressor will not run.
BACnet Schedule For use with a Building Automation System that supports native BACnet scheduling is scheduling the unit. With the Occupancy Source set to BACnet schedule the BAS will control the unit through network communication and it’s own scheduling function. BAS On/Off The Building Automation System is scheduling the unit via an On/Off command to the BAS ON/OFF software point.
580J Cooling The compressor outputs are controlled by the Cooling Control PID Loop and Cooling Stages Capacity algorithm. They will be used to calculate the desired number of stages needed to satisfy the space by comparing the Space Temperature (SPT) to the Occupied Cool Setpoint plus the T56 slider offset when occupied and the Unoccupied Cool Setpoint (UCSP) plus the T56 slider offset, if unoccupied. The economizer, if available, will be used for cooling in addition to the compressors.
If the calculated IAQ minimum position is greater than the IAQ maximum damper position configuration then it will be clamped to the configured value. Demand Limit If the RTU-- MP receives a level 1 (one degree offset), 2 (two degree offset), or a 3 (4 degree offset) to the BACnet demand limit variable, the controller will expand the heating and cooling setpoints by the configured demand limit setpoint value and remain in effect until the BACnet demand limit variable receives a 0 value.
