DESCRIPTION
Units are a single piece, electric cooling unit, with a low profile, pre-wired, tested and charged at the factory.
The units have the capability for convertible supply and return openings and are intended for installation on an
accessory curb (ordered separately), or for slab mounting (for horizontal duct connections). Units are designed
to accept a field-installed economizer, enthalpy control, manual or two-position outside-air damper, roof curb,
as well as many choices of field-installed electric heat. Refer to accessory chart below for full listing.
FEATURES
• Standard one-year full product warranty.
• Five-year protection plan for the motor-compressor.
• Outdoor ambient cooling operation from 25 F (–4 C) to 115 F (46 C).
• Units are tested and certified by ARI and certified by UL and CSA.
Factory-run test printout included in each rooftop.
• 24-volt control circuit, with resettable breaker.
• Two-inch disposable-type return air filters in dedicated rack.
• Hermetic compressor on independent circuit with internal line break and
overload protection, self-lubricating with internal discharge muffler.
• Scroll compressor with internal overload protection (50TFF007 and
50TFF014).
• Each refrigerant circuit contains a filter drier to trap dirt and particles.
• Single compressor on 3 to 6 ton units.
• Dual compressors on 7
