204 Part Number 80-1230-9 10/10CLEANUP PROCEDUREMild System Contamination1. Replace any failed components.2. If the compressor is good, change the oil.3. Replace the liquid line drier.NOTE: If the contamination is from moisture, useheat lamps during evacuation. Position them at thecompressor, condenser and evaporator prior toevacuation. Do not position heat lamps too close toplastic components, or they may melt or warp.4. Follow the normal evacuation procedure, exceptreplace the evacuation step with the following:A. Pull vacuum to 1000 microns. Break thevacuum with dry nitrogen and sweep thesystem. Pressurize to a minimum of 5 psig(35 kPa,.35 bar).B. Pull vacuum to 500 microns. Break thevacuum with dry nitrogen and sweep thesystem. Pressurize to a minimum of 5 psig(35 kPa,.35 bar).C. Change the vacuum pump oil.D. Pull vacuum to 500 microns. Run the vacuumpump for 1/2 hour on self-contained models,1 hour on remotes.NOTE: You may perform a standing vacuum test tomake a preliminary leak check. You should use anelectronic leak detector after system charging to besure there are no leaks.5. Charge the system with the proper refrigerant tothe nameplate charge.6. Operate the ice machine.ImportantDry nitrogen is recommended for this procedure.This will prevent CFC release.
