INVERTER TECHNOLOGY - - COMFORT
The inverter driven compressor is designed to run at various input
power frequencies (Hz) which controls the motor speed of the
compressor.
Even Temperature – The control package, including the inverter,
monitors outdoor and indoor temperatures as they relate to the
selected indoor set point and adjusts the speed of the compressor to
match the load and keep the system operating continuously rather
than cycling and creating temperature swings. This translates to
higher comfort levels for the occupants.
Rapid Pull Down/Warm- -Up – Comfort is increased by the
ability to the inverter system to ramp up the compressor speed to
enabling the system to reach the user selected room temperature set
point quicker.
Humidity Control – Running the system for longer periods and
continuously varying the compressor speed will enhance the
humidity control.
INDIVIDUAL ROOM COMFORT
Maximum comfort is provided because each space can be
controlled individually based on the usage pattern. The air sweep
feature provided permits optimal room mixing to eliminate hot and
cold spots for the occupant comfort.
LOW SOUND LEVELS
When noise is a concern, the duct free split systems are the answer.
The indoor units are whisper quiet. There are no compressors
indoors, either in the conditioned space or directly over it, and
there is none of the noise usually generated by air being forced
through ductwork.
When sound ordinances and proximity to neighbors demand quiet
operation, the 38GXQ unit is the right choice. With the inverter
technology, these units run at lower speeds most of the time
resulting in reduced sound levels.
INVERTER TECHNOLOGY – ENHANCED
ECONOMICAL OPERATION
Duct free systems are inherently economical to operate. Individual
rooms are heated or cooled only when required, and since the air is
delivered directly to the space, there is no need to use additional
energy to move the air in the ductwork. This economical operation
is enhanced further when the inverter system output matches the
load resulting in a more efficient system.
EASY- - TO- - USE CONTROLS
The high- -wall systems have microprocessor- -based controls to
provide the ultimate in comfort and efficiency. The user friendly
wireless remote control provides the interface between the user and
the unit.
SECURE OPERATION
If security is an issue, outdoor and indoor units are connected only
by refrigerant piping and wiring to prevent intruders from crawling
through ductwork or wall openings. In addition since the 38GXQ
can be installed close to an outside wall, coils are protected from
vandals and severe weather.
FAST INSTALLATION
This compact duct- -free split system is simple to install. A
mounting bracket is standard with the indoor units and only wires
and piping need to be run between the indoor and outdoor units.
These units are fast and easy to install ensuring minimal disruption
to customers in homes or workplace. This makes the 38/40GXQ
systems the equipment of choice for retrofit applications.
SIMPLE SERVICING AND
MAINTENANCE
Removing the top panel on outdoor units provides immediate
access to the control compartment, providing a service technician
access to check unit operation. In addition, the draw- -thru design of
the outdoor section means that dirt accumulates on the outside
surface of the coil. Coils can be cleaned quickly from the inside
using a pressure hose and detergent.
On all indoor units, service and maintenance expense is reduced
due to easy- -to- -use cleanable filters. In addition, these high wall
systems have extensive
troubleshooting.
BUILT- - IN RELIABILITY
Duct- -free split system indoor and outdoor units are designed to
provide years of trouble- -free operation.
Both the indoor and outdoor units are well protected. Whenever
the microprocessor detects abnormal conditions, the unit will stop
and an error code is displayed. For a complete list of abnormal
conditions that are detected refer to the Safety and Reliability
section in the Standard Features and Accessories on page 4.
Inverter systems provide additional reliability due to soft start. This
refers to the ability of the inverter to start the compressor motor
using reduced voltage and reduced current. This feature is
beneficial from an electrical standpoint (eliminates current spikes)
as well as an overall reliability standpoint due to reduced stress on
all associated system components.
ACCESSORIES
A condensate pump accessory is available to provide installation
flexibility for those applications where gravity cannot be used to
dispose of the condensate.
AGENCY LISTINGS
All systems are listed with AHRI (Air conditioning, Heating, and
Refrigeration Institute) and are ETL certified per UL 1995
standard.
