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 1/2 to 12 1/2 ton units.
