Filter drier must be replaced 550(26.34 kPa)and 625 psig(29.93 kPa)differential pressure. whenever the refrigerant system is opened.When removing a filter drier, use a tubing cutter to cut the drier from the system. Do not unsweat a A WARNING filter drier from the system.Heat from unsweating will release moisture and contaminants from drier into system. EXPLOSION,ENVIRONMENTAL SAFETY HAZARD Failure to follow this warning could result in personal injury,death or R-410A Refrigerant Charging equipment damage. Refer to unit information plate and charging chart. Some R-410A This system uses R-410A refrigerant which has higher operating refrigerant cylinders contain a dip tube to allow liquid refrigerant to flow from cylinder in upright position.For cylinders equipped with a dip tube, pressures than R-22 and other refrigerants.No other refrigerant may be used in this system. Gauge set, hoses, and recovery system must be charge R-410A units with cylinder in upright position and a commercial designed to handle R-410A If you are unsure, consult the equipment metering device in manifold hose.Charge refrigerant into suction-line. manufacturer. Troubleshooting Refrigerant System Use the Troubleshooting Guides(See Table 16,Table 17,and Table 18) if problems occur with these units. This information covers the refrigerant system including the compressor oil needed,servicing systems on roofs containing synthetic materials,the Start-up Checklist filter drier and refrigerant charging. Use Start-Upchecklist to ensure proper start-upprocedures are followed. Compressor Oil p p The Copeland scroll compressor uses 3MAF POE oil.If additional oil is needed, use Uniqema RL32-3MAF. If this oil is not available, use Copeland Ultra 32 CC or Mobil Arctic EAL22 CC.This oil is extremely hygroscopic,meaning it absorbs water readily. POE oils can absorb 15 times as much water as other oils designed for HCFC and CFC refrigerants.Take all necessary precautions to avoid exposure of the oil to the atmosphere. Rotary Compressor The 24 and 30 size units use a single cylinder rotary compressor. This compressor utilizes a rotor which is positioned eccentrically with respect to the shell. Refrigerant gas is ported directly into the compression chamber and discharged into the surrounding area.It is also known as a "high-side" design since high pressure gas surrounds the motor and compression chamber.The majority of the shell will be hot to the touch. The rotary compressor also utilizes an external built-in accumulator to reduce the likelihood of refrigerant liquid from entering the compressor. Servicing Systems on Roofs with Synthetic Materials POE(polyolester)compressor lubricants are known to cause long term damage to some synthetic roofing materials. Exposure, even if immediately cleaned up, may cause embrittlement (leading to cracking)to occur in one year or more.When performing any service that may risk exposure of compressor oil to the roof, take appropriate precautions to protect roofing. Procedures which risk oil leakage include, but are not limited to, compressor replacement, repairing refrigerant leaks, replacing refrigerant components such as filter drier, pressure switch, metering device, coil, accumulator, or reversing valve.
