INDUSTRY LEADING FEATURES / BENEFITS

AN INEXPENSIVE AND CREATIVE SOLUTION TO DESIGN PROBLEMS.

The 38HDR(QRR)/40QAC(QAQ) series duct--free split systems are a matched combination of an outdoor condensing unit and an indoor fan coil unit connected only by refrigerant tubing and wires.

The ceiling--suspended fan coils are ideal for retrofit and modernization projects where it is impractical or prohibitively expensive to run ductwork and where there are no false ceilings or wall space available. This selection of fan coils permits inexpensive and creative solutions to design problems such as:

the environmentally sound refrigerant

The ideal compliment to your ducted system when it is impractical or prohibitively expensive to use ductwork.

S Special space requirements such as garages.

S When changes in the load cannot be handled by the

existing system like restaurants.

S When adding air conditioning to spaces that are heated

by hydronic or electric heat and have no ductwork like schools.

S Historical renovations or any application where

preserving the look of the original structure is essential like churches.

These compact indoor fan coil units blend nicely with most ceilings and protrude less than 10 inches (254 mm) from the ceiling. Advanced system components incorporate innovative technology to provide reliable cooling performance at low sound levels.

LOW SOUND LEVELS

When noise is a concern, ceiling--suspended 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 38HDR/QRR unit is the right choice: The advanced, blow--through horizontal airflow design distributes air more evenly over the coil.

BUILT--IN RELIABILITY

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

The high wall indoor units include protection against freeze--up. The condensing units and heat pumps are also protected. There is

a three minute time delay before the compressor will start. An oversized accumulator on heat pumps, high and low pressure

switches ( loss of pressure switch on heat pumps), and compressor internal overload protection will ensure a robust system that is ideal for light commercial applications.

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 38HDR/QRR 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 units provide 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 to an outside wall.

The ceiling--suspended unit has its own mounting bracket for easier installation. Since there is no need to run ductwork and only piping and wiring is required between the indoor and outdoor units, there is minimal disruption to customers in the workplace, making this system ideal for retrofit applications.

40QAC/38HDR -- 40QAQ/38QR

SIMPLE SERVICING AND MAINTENANCE

Saving time and money was a big consideration when designing these systems.

On all indoor units, service and maintenance expense is reduced due to easy--to--use cleanable filters and the ability to service the unit from the bottom by removing the filter tracks.

On the outdoor units, a single panel provides immediate access to the isolated compressor and control compartment, allowing a service technician easy access 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 mild detergent without removing grilles or using fin combs.

INDIVIDUAL ROOM COMFORT

Maximum comfort is provided because each space can be controlled individually based on usage pattern. The ceiling--suspended units are equipped with motorized louvers which permits optimal room air mixing to eliminate hot and cold spots for occupant comfort. In addition, year--round comfort can be provided with heat pumps.

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 ceiling--suspended units have electro--mechanical controls and can be controlled by one of three user friendly thermostats that mount on the wall.

FLEXIBILITY

A variety of accessories simplify the installation process and help meet system requirements and weather considerations. Available accessories are listed in the Standard Features and Accessories section of this document.

OUTDOOR UNITS LOW AMBIENT KIT

The kit controls condenser fan cycling using a pressure switch. It is specifically designed to control fan--motor cycles in response to saturated condensing pressure. This device maintains a constant saturated condensing temperature of 100 _F ± 10 _F (37.78_C ±

--12.22 _C) at outdoor--air temperatures between 55 _F and --20 _F (12.78_C ± --12.22_C), and can be used on all outdoor units without changing the outdoor fan motor.

WINTER START CONTROL

The Winter Start Control is a SPST delay relay. the control bypasses the low pressure switch for approximately 3 minutes to permit start--up for cooling operation under low load conditions at low ambient temperatures. This relay is recommended on all systems that have the accessory Low Ambient Kit. Winter Start Control can also be used to provide low ambient cooling at outdoor ambient temperatures between 55_F and 40_F (12.8_C and 4.4_C).

ISOLATION RELAY

To be used when Low Ambient Kit is used with heat pumps. This will ensure that the pressure switch is bypassed if unit is running in heat pump mode.

LIQUID LINE SOLENOID VALVE

The Liquid Line Solenoid Valve is an electronically operated shutoff valve that is installed at the outdoor unit to stop and start refrigerant flow in response to compressor operation. The valve maintains a column of refrigerant in the liquid line between compressor operating cycles and is required for certain long--line applications and to improve system performance.

CRANKCASE HEATER

The Crankcase Heater is available for units with scroll compressors and clamps onto the compressor oil sump. It is recommended for low ambient and long line applications.

WIND BAFFLES

The Wind Baffle is an accessory sheet metal wrapper used to provide improved unit operation during high winds and is recommended whenever the Low Ambient Kit is used.
