2.0 GENERAL INFORMATION

The (-)ASL-series of condensing units are designed to operate using the Comfort
System™ or traditional 24VAC controls. These units are equipped with the
2
Control
System™ :
Comfort Control
2
Control
• (-)ASL condensing unit equipped with the Comfort Control
• An air handler or furnace equipped with the Comfort Control
• A Comfort Control
If your installation does not meet the above requirements, you must use traditional
24VAC controls.
This installation instruction manual contains complete instructions for installation
and setup using Comfort Control
the Engineering Specification Sheets for complete performance data, thermostat,
and accessory listings.
The information contained in this manual has been prepared to assist in the proper
installation, operation and maintenance of the air conditioning system. Improper
installation, or installation not made in accordance with these instructions, can result
in unsatisfactory operation and/or dangerous conditions (noise and component fail-
ure), and can cause the related warranty not to apply.
Read this manual and any instructions packaged with separate equipment required
to make up the system prior to installation. Retain this manual for future reference.
ANY
To achieve optimum efficiency and capacity, the indoor cooling coils listed in the
condensing unit specification sheet should be used.

2.1 CHECKING PRODUCT RECEIVED

Upon receiving unit, inspect it for any shipping damage. Claims for damage, either
apparent or concealed, should be filed immediately with the shipping company.
Check condensing unit model number, electrical characteristics and accessories to
determine if they are correct. Check system components (evaporator coil, condens-
ing unit, evaporator blower, etc.) to make sure they are properly matched.

2.2 APPLICATION

Before specifying any air conditioning equipment, a survey of the structure and a
heat gain calculation must be made. A heat gain calculation begins by measuring
all external surfaces and openings that gain heat from the surrounding air and
quantifying that heat gain. A heat gain calculation also calculates the extra heat
load caused by sunlight and by humidity removal.
Air conditioning systems are sized on the cooling load calculation. There are two
capacities that enable the equipment to provide comfort. The first is sensible capacity.
Sensible heat is the heat energy measured on the dry bulb thermometer as it is
added or removed.
The second form of heat is called latent or hidden heat. This is heat held in the
humidity in the air.
A properly-sized unit removes both forms of heat, producing a comfortable living
space. An oversized system cycles on and off too quickly and does not properly
remove humidity, producing an uncomfortable living space. Select the indoor and
outdoor equipment combination based on the manufacturer's engineering data.
After the equipment combination has been selected, satisfying both sensible and
latent conditioning requirements, the system must be properly installed. Only then
can the unit provide the comfort the manufacturer intends.
There are several factors that the installers must consider:
• Outdoor unit location
• System refrigerant charge
• Indoor unit blower speed
• System air balancing
. Your installation must have these components to use Comfort
