INDUSTRY LEADING
FEATURES / BENEFITS

AN INEXPENSIVE AND CREATIVE
SOLUTION TO DESIGN PROBLEMS.

The 38MGQ/40MAQ/40MB ductless inverter driven multi--zone
system provides individual comfort control for up to 5 separate
zones. Two, three, four or five space-- saving cassette, floor console,
high wall, or ducted fan coils can be matched with one outdoor
heat pump. The indoor fan coils are connected to the outdoor unit
by refrigerant tubing and wires.

The different styles of indoor units can be mounted in several
locations to accommodate the application. This selection of fan
coils permits inexpensive and creative solutions to design problems
such as:

S When adding air conditioning to spaces that are heated

by hydronic or electric heat and have no ductwork.

S Historical renovations or any application where

preserving the look of the original structure is essential.

S Commercial add--on jobs where the existing air

conditioning system cannot be stretched.

These compact indoor fan coil units take up very little space in the
room and do not obstruct windows. The fan coils are attractively
styled to blend with most room decors.

Advanced system components incorporate innovative technology
to provide reliable cooling and heating performance at low sound
levels.

INVERTER TECHNOLOGY

The inverter driven compressor is designed to run at various input
power frequencies (Hz) which controls the compressor’s motor
speed.

Even Temperature – The control package, including the inverter,
monitors the outdoor and indoor temperatures as they relate to the
selected indoor set point and adjusts the compressor speed 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
inverter system’s ability to ramp up the compressor speed 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 enhances 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, ductless 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 the
ductwork.

When sound ordinances and proximity to neighbors demand quiet
operation, the 38MGQ 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

Ductless 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 multi--zone systems have microprocessor--based controls to
provide the ultimate in comfort and efficiency. The user friendly
wired and wireless remote controls provide the interface between
the user and the unit.

FAST INSTALLATION

This compact ductless split system is simple to install. A mounting
bracket is included with the indoor units and only wires and piping
need to run between the indoor and outdoor units. These units are
fast and easy to install ensuring minimal disruption to customers in
homes or the workplace. This makes the 38MGQ/40MAQ/40MB
systems the equipment of choice for retrofit applications.

SIMPLE SERVICING AND MAINTENANCE

Removing the top panel of the outdoor unit provides immediate
access to the control compartment, providing the service technician
access to the diagnostic LEDs to facilitate the troubleshooting
process. In addition, the draw--thru design of the outdoor unit
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 the indoor units, service and maintenance expense is reduced
due to the permanent easy to clean filters. Also, error codes are
displayed on the front panel to alert the user to certain system
malfunctions

BUILT--IN RELIABILITY

Ductless split system indoor and outdoor units are designed to
provide years of trouble--free operation.

Both the indoor and outdoor units are well protec t ed. Whenever the
micr opr ocessor detects abnormal conditions, the unit stops and an
error code appear s.

Inverter systems provide additional reliability due to the 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.

CONDENSATE PUMP

A condensate pump accessory is available (High Wall and Floor
Console) to provide installation flexibility for those applications
where gravity cannot be used to dispose of the condensate.
Factory installed condensate pump on the Ducted and Cassette fan
coils provides installation flexibility.

AGENCY LISTINGS

All systems are listed with AHRI (Air conditioning, Heating, and
Refrigeration Institute) and are ETL certified per UL 1995
standard.

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 38MGQ
can be installed close to an outside wall, coils are protected from
vandals and severe weather.
