Manual 2100-218 Page 14 THREE PHASE SCROLL COMPRESSOR START UP INFORMATION Scroll compressors, like several other types of compressors, will only compress in one rotational direction. Direction of rotation is not an issue with single phase compressors since they will always start and run in the proper direction.
Manual 2100-218 Page 15 Low Pressure Switch, Bypass, and Lockout Sequence If the low pressure switch opens for more than 120 seconds, the compressor contactor will de-energize and go into a soft lockout. Regardless the state of the low pressure switch, the contactor will reenergize after the delay on make time delay has expired.
Manual 2100-218 Page 16 PRESSURE SERVICE PORTS High and low pressure service ports are installed on all units so that the system operating pressures can be observed. A pressure table can be found later in the manual covering all models. It is imperative to match the correct pressure table to the unit by model number.
Manual 2100-218 Page 17 REMOVAL OF FAN SHROUD 1. Disconnect all power to the unit. 2. Remove the screws holding both grilles, one on each side of unit, and remove grilles.
