LOW SOUND LEVELS
For applications like conference rooms or libraries where noise is a
concern, the in--ceiling cassette is 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 38HDF/QRF unit is the right choice: The advanced,
horizontal blow--through airflow design distributes air more evenly
over the coil.
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. In addition, since 38HDF/QRF units can be
installed close to an outside wall, coils are protected from vandals
and severe weather.
FAST INSTALLATION
The small footprint of the outdoor unit provides additional
benefits. Because they require minimal service and airflow
clearances, the outdoor units can be located virtually anywhere --
on the ground, roof, balcony, under a deck, or even mounted on an
outside wall.
The compact in--ceiling cassette requires less than 12 inches (304.8
mm) of false ceiling and the 40KMC018 unit fits into a 2’ X 2’
(0.6 m X 0.6 m) false ceiling.
These units are fast and easy to install ensuring minimal disruption
to customers in the workplace and making them ideal for retrofit
applications.
SIMPLE SERVICING AND
MAINTENANCE
Saving time and money was a big consideration when designing
these systems.
On the indoor unit, opening the grille will allow a service
technician access to the control box and to remove the cleanable
filters. There is even a plug to drain water from the condensate pan
if it is ever required.
On the outdoor unit, a single panel provides immediate access to
the isolated compressor and control compartment, allowing a
service technician to check the unit operation without a loss of
condenser airflow. In addition, the blow--through design of the
outdoor section means that dirt accumulates on the inside surface
of the coil. Coils can be cleaned from the outside using a pressure
hose and detergent without removing grilles or using fin combs.
BUILT--IN RELIABILITY
Duct--free split system indoor and outdoor units are designed to
provide years of trouble--free operation.
The in--ceiling cassette units include protection against freeze--up
and high evaporator temperatures on heat pumps.
The condensing units and heat pumps are also protected. There is
a 3--minute time delay before the compressor will re--start. An
oversized accumulator, high and low pressure switches (or liquid
line pressure switch on the heat pump), and compressor internal
overload protection will ensure a reliable system that is ideal for
light commercial applications.
INDIVIDUAL ROOM COMFORT
Maximum occupant comfort was key in the design of the
in--ceiling cassette units.
For instance, the indoor unit is equipped with a motorized louver
system that provides optimum air distribution into the conditioned
room. The user can select eight different louver operating modes
to adjust the airflow according to their specific needs.
The air can be distributed from four sides of the unit. This allows
the unit to be installed in the center of the room. For applications
where the unit has to be installed near a wall or in a corner, a
special kit is available to close one or two outlets.
On heat pumps, the controls have built--in features to automatically
compensate for air stratification and avoid cold blow on start--up or
during defrost.
ECONOMICAL OPERATION
The duct--free split system design allows individual room heating
or cooling when required. There is no need to run large supply--air
fans or chilled water pumps to handle a few spaces with unique
load patterns. In addition, because air is moved only in the space
required, no energy is wasted moving air through ducts.
EASY--TO--USE CONTROLS
The in--ceiling cassette units have microprocessor--based controls
to provided the ultimate in comfort and efficiency. Either a user
friendly wireless remote control or a wired controller provides the
interface between user and the unit.
FLEXIBILITY
A variety of accessories simplify the installation process and help
meet system requirements and weather conditions. See table of
available accessories on page 4.
