Convergence of Technological Innovation with Flexibility and Style
Single-Zone Four-Way Ceiling-
Cassette Systems
A four-way ceiling-cassette system provides a system designer an
edge to engineer a system with many user-adjustable settings. Four-
way ceiling cassette systems features a ceiling-recessed indoor unit
case and an off-white architectural grille (required; sold separately)
that is flush mounted, providing a clean look to the room. These sys-
tems are 208-230V/60Hz/1PH systems, available in nominal capaci-
ties of 3/4, 1, 1-1/2, 2, 3, and 3-1/2 tons, and are best suited in light
commercial applications or large, open spaces. The ceiling cassette
indoor unit is a useful alternative when wall space is limited.
Benefits of Four-Way Ceiling Cassette Systems
• Inverter technology
• Available in 9,000, 12,000, 18,000, 24,000, 36,000, 42,000 Btu/h
capacities
• All-season use—heat pump models for both cooling and
heating capabilities
• Operating ranges for 9,000 and 12,000 Btu/h outdoor units of
0°F to +118°F (DB) for cooling (Cooling range can be extended
from 0°F down to -4°F using the Low Ambient Wind Baffle Kit
[sold separately]); -4°F to +64°F (WB) for heating
• Operating ranges for 9,000 and 12,000 Btu/h indoor units of
57°F to 77°F (WB) for cooling; 59°F to 81°F (DB) for heating
• Indoor unit temperature setting range for 9,000 and 12,000 Btu/h
of 65°F to 86°F (DB) for cooling; 61°F to 86°F (WB) for heating
• Operating ranges for 18,000, 24,000, 36,000, 42,000 Btu/h
outdoor units of 5°F to +118°F (DB) for cooling; 0°F to +64°F
(WB) for heating
• Operating ranges for 18,000, 24,000, 36,000, 42,000 Btu/h
indoor units of 57°F to 77°F (WB) for cooling; 59°F to 81°F (DB)
for heating
• Indoor unit temperature setting range for 18,000, 24,000, 36,000,
and 42,000 Btu/h of 65°F to 86°F (DB) for cooling; 61°F to 86°F

Inverter Technology
Inverter variable-speed compressors are also measurably quieter
and consume less energy than those in conventional air condi-
tioners. The Inverter compressor ramps up or down to match the
required room capacity and maintain the comfort level. When the
selected temperature is reached, the inverter compressor operates
at low speed to maintain that comfort level, thereby using less
energy.
Adaptable and Flexible
Four-way ceiling-cassette systems allow cooling or heating for a
single room without the need for extensive remodeling. Long refrig-
erant piping lengths allow for extra design flexibility in indoor unit
installation. These units may be used for a number of residential or
commercial environments such as:
• Older homes
• New home construction
• Office buildings
• Restaurants
• Hospitals / Medical facilities
• Schools
• Nursing homes
• Retail establishments
• Houses of worship
