3.0 UNIT SPECIFICATIONS
3.3 Unit Features
CABINET —
Galvanized steel with a durable
painted finish. Stamped louvered panels offer
100% protection for the condenser coil.
COMPRESSOR —
The Scroll Compressor is
hermetically sealed with internal overload
protection and durable insulation on motor
windings. The entire compressor is mounted on
rubber grommets to reduce vibration and noise.
CONDENSER COIL —
Constructed with copper
tubes and aluminum fins mechanically bonded to
the tubes for maximum heat transfer capabilities.
BASE PAN
— Galvanized steel with powder coat
paint finish.
REFRIGERANT CONNECTIONS
— Field piping
connections are made through a fixed panel. This
allows complete access or removal of access
panels after piping connections have been made.
CRANKCASE HEATER
— Standard, all models.
Prevents refrigerant migration to compressor(s).
LOW AMBIENT CONTROL (OPTIONAL)
— A
pressure sensitive fan cycling control to allow unit
operation to 0°F is field installed.
SERVICE VALVES
— Standard on liquid and
suction lines. Allows outdoor section to be isolated
from indoor coil.
SERVICE ACCESS
— Control box as well as
the compressor and other refrigerant controls
being accessible through access panels. Control
box may be open without affecting the normal
operation of the unit. Condenser fan motors are
accessible by removing wire grilles.
FILTER DRIER
— Standard (uninstalled) on all
models. Helps ensure refrigerant cleanliness.
TRANSFORMER
— Step down type, line to 24
volts. Provides control circuit voltage.
CONTACTOR
— The contactor is an electrical
switch which operates the compressor and
condenser fans.
HIGH PRESSURE CONTROL
— Opens the
contactor circuit on high refrigerant pressure;
manual reset.
LOW PRESSURE CONTROL
— Stops
compressor operation in the event of loss of
refrigerant.
CONDENSER MOTOR
— All condensers utilize
(ECM) Brushless permanent magnet motors.
TESTING
— All units are run tested at the factory
prior to shipment. Units are shipped with a holding
charge of nitrogen.
EXTERNAL GAUGE PORTS
— Allows pressures
to be checked without removing access panel.
COIL LOUVERS
— Helps prevent damage to
outdoor coils.
TIME DELAY
— Supplied on tandem compressor
models to provide a delay between stages.
EQUIPMENT GROUND
— Lug for field connecting
of ground wire.
