50TFF007
50TFF008-014
50TFF007-014
Electric Cooling
50 Hz
(5 to 10.2 Tons)
Single-Package Rooftop Units with:
• Galvanized pre-painted steel
cabinet
• Fifty-one mm (2-in.) return-air filters
• Commercial strength base rails
• Exclusive tool-less filter access
panel
• Corrosion-resistant sloped
condensate pan
• Single power entry to unit
• Commercial duty motors with
permanently lubricated bearings
• Standard cooling operation at
outdoor ambient temperatures as
low as –4 C (25 F)
• Meets ASHRAE Standard 62
(Indoor Air Quality)
Features/Benefits
Compact, vertical discharge
units convert to horizontal
discharge, combining
installation flexibility with
efficient performance and
easy maintenance.
Easy installation and
conversion
All units are shipped in the vertical dis-
charge configuration for fit-up to
standard roof curbs. (Two different curb
sizes fit unit sizes 007 and 008-014.)
The contractor can order and install the
roof curb early in the construction
stage, before decisions on size require-
ments are made.
All units feature roll-formed baserail
design with forklift slots on 3 sides and
rigging holes for easier maneuvering.
Durable packaging protects all units
during shipment and storage.
The units can be easily converted
from a vertical to a horizontal
discharge configuration by interchang-
ing the panels supplied with the unit.
