LEGEND
*Evaporator coil fin material/condenser coil fin material. Contact your local
representative for details about coated fins.
†Weight of 14-in. roof curb.
**Single phase/three-phase.
††Rollout switch lockout is manually reset by interrupting power to unit or
resetting thermostat.
||48TFG, TFH, and TFK units are California compliant three-phase high heat
models.
***Three-phase standard high heat models have heating input values as
shown. Single-phase standard high heat models have one-stage heating
with heating input values as follows:
48TFF004 — 115,000 Btuh
48TFF005,006 — 150,000 Btuh
†††California SCAQMD compliant Low NO
x
models have combustion prod-
ucts that are controlled to 40 nanograms per joule or less.
¶Steady State Efficiency is 80% on all units except 48TFK004, which is
81%.
NOTE: High-static motor not available on single-phase units.
