Accessory Description and Usage
AHRI Standard Capacity Rating Conditions
AHRI STANDARD 210/240 RATING CONDITIONS —
(A) Cooling 80°F DB, 67°F WB air entering indoor coil,
95°F DB air entering outdoor coil.
(B) High Temperature Heating 47°F DB, 43°F WB air entering
outdoor coil, 70°F DB air entering indoor coil.
Anti-Short Cycle Timer — Solid state timing device that
prevents compressor recycling until 5 minutes have elapsed
after satisfying call or power interruptions. Use in area with
questionable power delivery, commercial applications, long
lineset, etc.
(C) Low Temperature Heating 17°F DB, 15°F WB air entering
outdoor coil, 70°F DB air entering indoor coil.
(D) Rated indoor airflow for heating is the same as for cooling.
Evaporator Defrost Control — SPST Temperature actu-
ated switch that cycles the condenser off as indoor coil
reaches freeze-up conditions. Used for low ambient cooling
to 30°F with TXV.
AHRI STANDARD 270 RATING CONDITIONS — (Noise
rating numbers are determined with the unit in cooling
operation.) Standard Noise Rating number is at 95°F outdoor
air.
Rubber Isolators — 5 large rubber donuts to isolate
condensing unit from transmitting energy into mounting
frame or pad. Use on any application where sound transmis-
sion needs to be minimized.
Hard Start kit — Start capacitor and relay to assist compressor
motor startup. Use in areas with marginal power supply, on
long linesets, low ambient conditions, etc.
Extreme Condition Mount Kit — Bracket kits to securely
mount condensing unit to a frame or pad without removing any
panels. Use in areas with high winds, or on commercial roof
tops, etc.

Specification Options
General
Condenser Coil
The 2TWB3 is designed to operate at
outdoor ambient temperatures as high
as 115°F. Cooling capacities are
matched with a wide selection of air
handlers and furnace coils that are AHRI
certified. The unit is certified to UL 1995.
Exterior is designed for outdoor applica-
tion.
The outdoor coil provides low airflow
resistance and efficient heat transfer.
The coil is protected on all four sides
by louvered panels.
Low Ambient Cooling
As manufactured, this unit has a cooling
capability to 55°F. The addition of an
evaporator defrost control permits
operation to 40° F. The addition of an
evaporator defrost control with TXV
permits low ambient cooling to 30° F.
Casing
Unit casing is constructed of heavy
gauge, G90 galvanized steel and painted
with a weather-resistant powder paint on
all louvers, panels, prepaint on all other
panels. Corrosion and weatherproof
CMBP-G30 DuraTuff™ base.
Accessories
Thermostats — Cooling only and heat/
cooling (manual and automatic
changeover). Sub-base to match thermo-
stat and locking thermostat cover.
Refrigerant Controls
Refrigeration system controls include
condenser fan, compressor contactor
and low pressure switch. High and low
pressure controls are inherent to the
compressor. A factory installed liquid line
drier is standard.
Evaporator Defrost Control — See Low
Ambient Cooling.
Compressor
The Climatuff® compressor features
internal over temperature and pressure
protection and total dipped hermetic
motor. Other features include: roto lock
suction and discharge refrigerant
connections, centrifugal oil pump and
low vibration and noise.
