Data
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.
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.
AHRI STANDARD 270 RATING CONDITIONS — (Noise
rating numbers are determined with the unit in cooling opera-
tion.) Standard Noise Rating number is at 95°F outdoor air.
Evaporator Defrost Control — SPST Temperature actuated
switch that cycles the condenser off as indoor coil reaches
freeze-up conditions. Used for low ambient cooling to 30°F
with TXV.
Rubber Isolators — 5 large rubber donuts to isolate con-
densing unit from transmitting energy into mounting frame or
pad. Use on any application where sound transmission needs
to be minimized.
Hard Start kit — Start capacitor and relay to assist compres-
sor 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 4TWB4 is fully charged from the
factory for up to 15 feet of piping. This
unit 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 application.
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 cool-
ing capability to 55°F. The addition of
an evaporator defrost control with TXV
permits low ambient cooling to 20° F.
Casing
Accessories
Unit casing is constructed of heavy
gauge, G90 galvanized steel and
painted with a weather-resistant powder
paint
Thermostats — Cooling only and heat/
cooling (manual and automatic change-
over). Sub-base to match thermostat
and locking thermostat cover.
on all louvers, panels, prepaint on all
other panels. Corrosion and weather-
proof CMBP-G30 DuraTuff™ base.
Refrigerant Controls
Refrigeration system controls include
condenser fan and compressor contac-
tor. High and low pressure controls are
inherent to the compressor. A factory
installed liquid line drier is standard.
Compressor
The Climatuff® compressor features
internal over temperature and pressure
protection and total dipped hermetic
motor. Other features include: centrifugal
oil pump and low vibration and noise.
