Introduction
INTRODUCTION The Airedale Cassette units effectively make each area served an independent controlled
temperature zone. Through thermostatic control of operations, conditions can be varied to
suit diverse requirements or activities. Optional fresh air intakes are available to provide for
ventilation and recirculation of room air.
Airedale Cassettes are available in a choice of three models – DX cooling and heat pumps
in five model sizes and chilled water cooling in six model sizes – to properly match units to
job requirements. Optional heating can be provided by factory installed electric heat or hot
water modules, depending on model. This versatility eliminates compromising architecture
or design. Important cost savings are often realized during building modernizations, as
existing piping and/or wiring can frequently be reused.
Design techniques are incorporated in every Airedale Cassette to reduce noise levels to an
absolute minimum. These techniques include low blower speeds, rigid panel and cabinet
construction, and sound-absorbent cabinet insulation.
For individual comfort, Airedale Cassettes are available with electro-mechanical or micro-
processor based controls. The micro-processor controller includes an infrared transmitter
which enables room conditions to be maintained at a user defined set point. Airedale
Cassettes are also available with Carel microprocessor controls and network cards to allow
units to be connected to a Building Management System.

STANDARD FEATURES
Construction Cases are manufactured from lightweight galvanized sheet steel with integral fan mounting
rails for added strength. Fire resistant foam insulation (to UL94 VO) is fitted internally to
provide both thermal and acoustic insulation.
Evaporator All direct expansion units include a factory installed thermal expansion valve and utilize large
surface area evaporator coils ideally positioned to optimize heat transfer and airflow. Each
evaporator is manufactured from refrigeration quality copper tubes with mechanically bonded
aluminum fins.
Chilled Water Coil All chilled water units utilize large surface area coils positioned to optimize heat transfer and
airflow. Each coil is manufactured from refrigeration quality copper tubes with mechanically
bonded aluminum fins and are circuited from headers to ensure low water pressure drops.
Fan All units, utilizing backward curved centrifugal fans, are staticly and dynamically balanced for
quiet operation. Fan impellers are made from either aluminum or fire retardant plastic (UL94
VO) for light weight and corrosion resistant operation. Fans are driven by an enclosed multi-
speed external rotor motor allowing good heat dissipation and an increased motor efficiency.
Fans come complete with thermal overload protection and sealed-for-life lubricated bearings.
Filtration Wire framed filters are fitted. These are re-usable and may be vacuum cleaned.
Condensate Pump A condensate pump and check valve are fitted to carry water out of the unit and stop water
from flowing back into the condensate tray. The pump is fixed to a mounting bracket which
can be withdrawn from the side of the chassis and incorporates an inspection hole to allow a
visual check of the pump during operation. A float switch is fitted to stop the cooling action
should the pump become blocked or fail.
Air Vanes Air outlet vanes are designed to prevent condensation from forming. Vanes are manually
adjustable on the 2 x 2 model units but driven by an electric motor on all other model units.
Where fitted, the motorized air vanes can be set to auto sweep or can be stopped in a fixed
position. Polystyrene blanking pieces are supplied with Cassette packing so that up to two
fascia discharge slots can be blanked off.
Alarm Status Relay The unit shall include a relay for unit failure notification. Normally open contact available for
field connection.
Start / Stop Terminals The unit shall include terminals for remote start/stop of the unit. The unit is enabled when
contact between the terminals is closed. (only on Electro-Mechanical controls)

Ceiling Cassette
General Description
FACTORY INSTALLED OPTIONS
Controls Option 1:
Electro-Mechanical
The unit shall be factory wired with an electo-mechanical control system that includes the necessry
relays and safety switches for proper unit operation. Terminal strip provide at the unit for the wiring of a
24V wall mounted thermostat required for unit operation.
Controls Option 2:
Microprocessor
A custom designed microprocessor is fitted to the Airedale Cassette to enable room conditions to be
maintained at a user defined set point. Communication to the controller is by a hand held infrared
transmitter or a wall mounted ‘pendant’ transmitter. Each type of transmitter includes a wall mounting
bracket as standard.
Note: Units with Microprocessor controls can not be connected to a BMS. Select the Electro-Mechanical
controls option, for field installed BMS interface, or the Carel controller version with optional
Lonworks and BACnet network cards.
The microprocessor allows five operating modes: fan only, dry cooling, cooling only, heating only, and
heating/cooling with auto changeover for maximum versatility. A temperature set point between 58ºF and
90ºF can be selected.
The microprocessor monitors indoor coil temperature and return air temperature. The receiver contains a
self diagnostic feature. When a low indoor coil temperature is detected the cooling action is stopped. If a
sensor fails then an alarm is displayed on the fascia mounted receiver. The microprocessor also limits
the number of compressor starts per hour to reduce wear on the compressor.
The infrared/pendant transmitter is used to switch the unit ON/OFF, change temperature settings, fan
speed, operating mode, and to toggle the motorized air sweep (where fitted). The microprocessor also
has a built-in clock which can be activated to enable the unit to be programmed with up to two separate
operating periods on weekdays (Mon-Fri).
The clock provides ON/OFF unit operation and is not a night set back or occupied/unoccupied control
function. Mon-Fri will operate as a ‘block’ of days and cannot be programmed independently of one
another. Saturdays and Sundays can each be programmed with up to two separate operating periods
and are programmed independently of the weekdays and each other.
A fascia mounted receiver displays ON/OFF, cool or heat, and timer/alarm status.
Controls Option 3:
Carel Controller
The unit shall be fitted with a programmable microprocessor controller designed to operate the unit
according to pre-engineered control strategies. The Carel controller requires a wall sensor, wall stat or
network interface card.

compatibility with FT-10 LonWorks control system.
BACnet Card for Carel
Controller
The Carel microprocessor controller shall come equipped with a plug-in card allowing for complete
compatibility with an MS/TP BACnet control system.
Time Clock Card for
Carel Controller
A time clock (card) shall be provided for “stand-alone” units where time functions, night and weekend
setback, etc. are not transmitted from a building management system or remote central time clock. The
time clock shall have a full 7 day schedule and calendar function incorporated. The 7 day schedule shall
have two adjustable occupied/unoccupied periods per day. The calendar function shall allow 20
calendar periods (start date / stop date = 1 period).
Electric Heat Electric heating elements will be factory fitted to the unit. Elements are manufactured for maximum
surface area and lower working temperature for improved reliability. Thermal cut out protection switches
are fitted to the electric heat circuit to protect against overheating.
Hot Water Coil A hot water heating coil will be factory fitted (depending on unit size) in addition to the standard DX or
chilled water coil to provide heating. The coil is manufactured from refrigeration quality copper tubes with
mechanically bonded aluminum fins.
Hot Water Coil Freeze
Protection
The unit shall be fitted with a freeze protection sensor to prevent freezing of the hot water coil assembly.
When the sensor detects a freeze up condition it will force the flow control valve open and prevent the
unit fan(s) from running.
Disconnect Switch The unit shall be fitted with a power disconnect switch located on the control panel, sized for the full load
amperage of the unit to enable the unit to be disconnected from the power supply prior to any
maintenance.
Step Up Transformer The unit shall be fitted with a 115V to 230V step up transformer for 115V supply power. Note: This
