piece design adds greater water integrity. Rounded
corners with water drip edges add to the attractive
appearance. The cabinet panels have a non-fibrous
insulation that will not release insulation fibers into
conditioned area.
•
Top Discharge
- The top discharge condenser fan does
not disrupt neighboring areas or dry-out vegetation
surrounding the unit. The warm air from the top mounted fan
is blown up away from the structure and any landscaping.
This allows compact location on multi-unit applications.
•
Condenser Coil Grille
- A multi-piece totally enclosed,
rigidly mounted condenser coil grille provides protection
from objects after installation and provides protection
during transit.
•
Low Operating Sound Level
- The upward air flow
carries the normal operating noise up and away from the
living area. The rigid top panel effectively isolates any
motor sound. Isolator mounted compressor and the
rippled fins of the condenser coil muffle the normal fan
motor and compressor operating sounds. The unique
formed base pan also aids in sound alterations with it's
Super-Structure design. This design strategically places
embossments in the pan for optimum strength and rigidity.
•
Fan System
- All models operate over a wide range of
design conditions with an electrically commutated fan
motor. These units easily match all types of applications
and provide greater on site flexibility to match comfort
requirement. The cooling speed is factory set and can be
field adjusted to a second speed. The heating speed is
factory set to maintain mid point rise at the units heating
input, but can be field adjusted. This allows maximum
comfort conditions.
•
Simple Control Circuit
- A low voltage printed circuit
board contains a diagnostic indicator light and a low
voltage terminal strip. An additional set of pin connectors
is also provided to simplify the field interface of external
controls. Mate-n-lock plug connectors are used. The
electrical control box is not located in the compressor
compartment. The controls are mounted on a Control-Tilt
control panel to allow the access cover to be removed for
trouble shooting and maintenance without affecting the
normal system operating pressures. All wiring internal to
the unit is color/number coded.
•
Protected Compressor
- The compressor is internally
protected against high pressure and temperature. This is
accomplished by the simultaneous operation of high
pressure relief valve and a temperature sensor which protect
the compressor if undesirable operating conditions occur.
•
Pressure Switches
- High pressure and low pressure/
loss of charge switches standard in all units. When
abnormal conditions are sensed through the pressure
switches, the unit will lock out preventing any further
operation until reset or problem is corrected.
•
Exclusive Coil Design
- Grooved copper tubes and
enhanced aluminum fin construction improves heat
transfer for maximum efficiency and durability.
•
Heat Exchangers
- Are corrosion-resistant, aluminized-
steel tubular construction to provide long-life, trouble-free
operation. The unique blow-through design also assures
that condensate does not collect in humid areas when in
the cooling cycle. This adds to longer heat exchanger life
and higher long term efficiencies.
•
Post Purge Induced Draft Combustion
- Exhausts
combustion products from the heat exchanger upon
completion of the heating cycle to prolong the heat
exchanger life.
•
Self Diagnostic Fan Control Module
- Due to this self
diagnostic control, less on site time is required to trouble
shoot these units.
•
Spark To Pilot Ignition
- Provides faster heat delivery.
This ignition is highly reliable, durable and eliminates
nuisance lockouts.
•
Multi Port In-shot Burners
- No field adjustment is
required to mix the air and gas. These burners are
constructed of high-grade corrosion-resistant, aluminized-
steel.
•
Low Maintenance
- Long life, permanently lubricated
condenser and evaporator fan motor bearings need no
annual maintenance adding greater reliability to the unit.
Blower assembly can be easily cleaned by the unique
Slip- Track slide-out blower assembly.
•
Secured Service Access Ports
- Protected, externally
mounted, re-usable service access ports are provided on
both the high and low lines for ease of evacuating and
charging the system. No final field mounting required.
•
Easy Service Access
- A large, single panel covers the
electrical and gas controls makes servicing easy. The
blower compartment has an additional large panel with a
built-in handle tab. Removing this panel will allow the
blower assembly to slide-out for easy removal for
maintenance and ease of trouble shooting.
•
Replacement Parts
- The installer requires no special
training to replace any of the components of these units
and does not need to maintain an inventory of unique parts.
•
System Integration
- Each unit has the internal ability to
integrate an electronic air cleaner or humidifier to work in
conjunction with the base unit.
