• Refrigerant: R-404A
• Compressors: Copeland or Tecumseh hermetic by model
• Expansion valves: Non adjustable, internally equalized, one per evaporator.
• Hot gas valves: Pilot operated, line voltage coils. One per plate.
• Condensers: Forced draft air, counterow water. All air cooled models have left side air inlet.
• 48” wide air cooled models also have front air inlet. All air cooled models exhaust air out the back.
• Air lters: Surface mounted to panels. Filter media removable without removing panels.
• Fan blades: Reduced vibration blades in most air cooled models.
• Remote Systems: Head pressure control valves in condenser. No check valves. Headmaster protected by
lters (not lter driers). Controller pumps unit down by closing the liquid line valve and keeping the compressor
on for a xed time period at shut down.
• Fan pressure control. All AC. Controls fan motor operation in the freeze cycle.
