DESCRIPTION |
|
|
Units are a single piece, gas heating/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 fieldinstalled economizer, enthalpy control, manual or 2-position outside air damper, roof curb, as well as 3 choices of gas heat. Refer to accessory chart below for full listing.
FEATURES
•Standard one-year full product warranty.
•Five-year protection plan for the motor-compressor.
•Five-year protection plan on heat exchangers.
•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 (TF/TM007, TM012, TF014).
•Refrigerant circuit contains a filter drier to trap dirt and particles.
•Single compressor on 3 to 6 ton units.
•Dual compressors on 71/2 to 121/2 ton units.
•Two-speed direct drive evaporator fan on all units except 007 size which is belt driven. Adjustable belt drive fans are optional on all sizes.
•Non-corrosive condensate pan with self-draining sloping design with both bottom and side drain connections.
•Thru-the-bottom power control and gas entry capability.
•Indoor and outdoor coils constructed of aluminum fins mechanically bonded to seamless copper tubes.
•Single point electrical and gas connections.
•Direct drive propeller condenser fan totally enclosed with permanently lubricated bearings.
•Pre-painted, insulated cabinet with primer inner panels, certified 500-hr salt spray test and non-corrosive screws.
•Dedicated L,M,N 3 to 5 ton “Low NOx” units that meet California air quality refrigerant of 40 nanograms/joule or less.
•Large, easily removable panels provide ready access to unit components for rapid removal or maintenance.
•Filter access door for filter access and maintenance that requires no tools.
•Induced draft (negative pressure) combustion system with Hall effect sensor to detect proper operation of induced draft motor.
•All units have single stage cooling and single stage heating capability. High heat models have 2-stage heating capability.
•Heavy Alumagard™ coated heat exchangers, with aluminized steel burners.
•Heating controls with direct spark ignition and redundant gas valve. Fan switch, high temperature limit switch and flame rollout switch standard.
•Fixed orifice metering device precisely controls refrigerant flow to each circuit individually.
•Reliable accurate control circuit with color coded wires and easy accessible terminal board.
•Integrated gas control board with built-in diagnostics to determine error codes and control indoor fan on/off delays.
•Integrated gas control board provides anti-cycle protection for gas heat operation.
•Loss of charge (low pressure), freeze protection, and high pressure switches standard.
•Refrigerant filter drier/circuit.
