When this option is not included, a field-supplied disconnect switch should be installed in the power supply wiring at a location that will meet the requirements of the National Electric Code and/or local regulations. NOTE. Fused discormect switches are not required because the power wirirrgmust be fused at [he source. 2.

530.25-N1 SOLID STATE CONTROLS - A Honeywell W973 solid state Ioglc panel controls the econcrmi~,ermotor and stagesof coohng and heating in response to a signal from a dual set point thermostat located in the controlled space or a dual set point transmitter with a remote sensor located in the controlled space. To maintain stable space temperatures, the ]oglc panel balances the space thermostat demand s]gnal against the system output.

530.25-N1 - After the movable flange (or flanges) has been rotated to the proper number of “turns open”, the set screws should be tightened against the flats on the barrel to lock the nlovable flange in place. If the pulley includes a locking collar, the locking collal must be loosened to adjust the setting of t}le movable flange. To determine the deflection distance from normal position use a straight edge from sheave to sheave as a reference line. Note the fcrllowing: BELT SECTION “B” “c” 1.

530.25-N1 START-UP - CRANKCASE HEATERS It is important that the crankcase heaters be energved 8 hours before starting the compressors. To energize the crankcase heaters, the room thermostat or status panel system switch must be open to prevent the compressor from starting. If a disconnect switch is installed outside the unit, turn it to “ON”. The nonfused disconnect (optional) located in the unit’s main supply panel must also be turned ‘ON”. 7.

Solenoid 3SOL m the Ilqud IIne ISnow closed and the compressor pumps most 01 the rclrlgcrant out of’the evdpor:itor to the high side of the syftcm. The sys[cm srrctIon pressure drops until the low pressure cu[off ( 1LP) opens. This WIIIshrrt down the compressor and de-energizesthe 12TR relay which opens 12TR-2 to put the opcratlon of’the compressor under the control of the I R relay.
