DESCRIPTION
ARI STANDARD
360
48TM units are one-piece rooftop cooling units with gas heat. All units are pre-wired and
pre-charged with R-22 at the factory. Units are factory tested in both heating and cooling modes.
The 48TM units have bottom air openings for separate supply and return ductwork. The 48TMD
model is low heat and the 48TMF model is high heat. The 48TMM model is low heat with
stainless steel heat exchangers and the 48TMN model is high heat with stainless steel heat
exchangers. The 48TM unit is intended for installation on an accessory curb (ordered separately).
Horizontal supply and return connections are also possible with a factory-preassembled,
high-static regain, horizontal conversion adapter roof curb accessory (ordered separately).
Bottom discharge on concentric applications requires a transition duct (field-supplied) external to
the unit.
FEATURES
All units meet ASHRAE Standard 90.1.
Standard one-year product warranty.
Five-year non-prorated warranty on Alumagard™ coated Turbotubular™ gas heat exchanger.
Five-year warranty on the compressor (48TM016). One year warranty
on the compressor (48TM020-028).
Units are rated in accordance with ARI standard 360. Standard unit is
certified and listed by ETL and ETL, Canada.
Low outdoor temperature cooling operation to 40 F (4 C) as standard.
Dual freezestat protection is provided as standard.

2-stage gas heat in a single 2-stage gas valve.
Induced draft combustion system with Hall effect sensor to detect
proper operation of induced-draft motor.
Heavy Alumagard coated heat exchangers with aluminized steel
burners.
Optional stainless steel heat exchangers.
Heating controls with solid-state direct spark ignition system (pilotless
system) and redundant gas valve. High temperature limit switches and
auto-reset flame rollout switch are standard.
Reliable IGC (integrated gas unit controller) with built in diagnostics
to determine error codes and control fan on/off delays for energy
savings and maximum comfort control.
Integrated gas unit controller provides anti-cycle protection for gas
heat operation.
