Designed for durability in any climate,
the weather-resistant cabinets are constructed of galvanized steel, bonderized, and all exterior panels are coated
with a prepainted baked enamel finish.
The paint finish is non-chalking, and is
capable of withstanding ASTM (American Society for Testing and Materials)
B117 500-hour Salt Spray Test. Allinternal cabinet panels are primed,
permitting longer life and a more
attractive appearance for the entire
unit. In addition, ALL 50TFF units are
designed with a single, continuous top
piece to eliminate any possible leaks.
Totally enclosed condenser-fan motors
and permanently lubricated bearings
provide additional unit dependability.

Easy installation and
conversionIndoor-air quality begins with
Carrier rooftops

All units are shipped in the vertical discharge configuration for fit-up to
standard roof curbs. (Two different
curb sizes fit unit sizes 004-007 and
008-014 respectively.) The contractor
can order and install the roof curb early
in the construction stage, before decisions on size requirements are made.
All units feature roll-formed base raildesign with forklift slots and rigging
holes for easier maneuvering. (Forklift
slots are found on 3 sides.) Durable
packaging protects all units during
shipment and storage.
The units can be easily converted
from a vertical to a horizontal discharge configuration by interchanging
the panels supplied with the unit.
The non-corrosive sloped condensate pan permits either an external,horizontal, side condensate drain (outside the roof curb) or an internal, vertical, bottom drain (inside the roof curb).
Both options require an external, fieldsupplied P-trap.
Field-installed electric heaters are
available in a wide range of capacities.
Single point wiring kit makes installation simple.
The 50TFF units were designed with
the service technician in mind. The
single-row condensercoils on the
50TFF004 and 008 units simplify the
cleaning process. In addition, the
50TFF004-014 units have a standard
filter access panel, which permits toolless filter changes, even on units with
horizontal economizers.

Sloped condensate pans minimize biological growth in rooftop units in
accordance with ASHRAE (American
Society of Heating, Refrigeration, and
Air Conditioning Engineers)Standard 62. Two-in. filters with
optional dirty filter indicator switch
provide for greater particle reduction in
the return air. The face-split evaporator
coils on sizes 008-014 improve the
dehumidification capability of the standard units, and standard enthalpy controls provided with the optional or
accessory economizers maximize building humidity control.

Simple electricalconnections
Terminal boards, located in the base
unit control box, facilitate connections
to room thermostat, outdoor thermostat(s), economizer, and electric
heat. Service panels are quickly
removed, permitting easy servicing.
Thru-the-bottom utility connection
capability allows power and control
wiring to be routed through the unit
basepan, minimizing roof penetrations.
