• Stainless steel screws prevent rust streaks  
• Panels on ends quickly remove for complete access to refrigerant components and electrical terminal block during  
installation and servicing  
• Quick disconnect, waterproof plug and receptacle for each motor in all models  
• Wire fan guards with PVc coating for durability  
Coil  
• High-efficiency aluminum fins with full collars cover mechanically expanded copper tubes  
coils are dehydrated and sealed at the factory  
• Highest quality tubular heaters provide fast and economical defrost  
• Generous coil surface gives proper compressor balance  
• Standard adjustable defrost termination fan delay thermostat  
Drain Pan  
• Double drain pan eliminates drain pan sweating  
• Tapered mounting provides proper slope for condensate drainage to one end of the unit  
Motors  
• Motors are life lubricated and thermal overload protected  
• Ec motors (optional) available factory-installed or as a drop-in replacement through InterLink™ commercial  
Refrigeration Parts in 115/1/60, 208-230/1/60 voltages  
• PSc motors are optional for 115/1/60, 208-230/1/60 voltages  
• PSc motors or Ec motors are required for 50 Hz operation  
Options  
• Unit configurations: mounted components, pre-assembled, pre-charged and beacon II™  
- Units available with mounted TXV and mounted TXV / solenoid valve  
- Pre-assembled units come with mounted TXV, liquid line solenoid valve and room thermostat  
- Pre-charged units come with mounted TXV, liquid line solenoid valve, room thermostat and quick connect fittings  
- Mounted room thermostat  
- beacon II units come with electronic expansion valves, pressure transducer, temperature sensors and beacon  
control board  
• Most models available with glycol circuiting (see glycol product brochure)
