Additional Information

HIGH PERFORMANCE HEATING
Heating capacity at low outdoor
temperatures was improved by adopting
a large heat exchanger and a high
capacity compressor. Standard rated
heating capacity is maintained down
to 3°F. RLFFH models will deliver more
than 73% of rated heating capacity at
-15°F.
SUPER QUIET OPERATION
Floor mounts provide a peaceful
inside environment for sleep and
study with whisper quiet noise
levels down to 23 dB(A).
MULTI-ZONE
COMPATIBLE
As part of the HFI line, indoor
floor mount models are also
compatible in multi-zone
configurations when paired
with multi-zone outdoor models. Multi-zone specifications vary
from single zone specifications. See multi-zone brochure for
details.
BASE FREEZE PREVENTION
• Equipped with a base heater that
prevents condensate from freezing
• Cultivated base design discharges
melted water through many holes.
• Without a heater, freezing condensate
can cause noise, damage to fan blade,
condenser, and system performance.
