This will help you obtain the full value from your air conditioner. It will also help you avoid any needless service costs that result from causes we cannot control and cannot cover in our guarantee. RULES FOR INSTALLATION AND SAFE OPERATION 1. Read these rules and the instructionscarefully. Failure to follow the rules and the instructions could cause a malfunction of the air conditioning unit resulting in injury, 4. Refer to Section VIII for maintenance procedures. 5. Do notoperate this unit at outdoor temperatures below 60°F on cooling. 6. The components of an air conditioner may have sharp edges or protrusions which can cut you. The tubing and compressor contain high pressure refrigerant. They must hot be exposed to high temperature or be punctured. When installing or servicingthe air conditioner, be extremely careful to avoid injury. death and/or property damage. 2. Check your local codes and utility startdan:Is. The installation must comply with their rules. . Shut off the electric power before making connections on the unit or removing panels .for servicing. (There may be more than one disconnect). The importance of proper installationcannot be overemphasized. The best designed unitwill appear to operate poorly if installed improperly. Unlike the small appliance where quality of operation can usually be determined as it leaves the factory, the performance of an air conditioner depends, to a large extent, on its installation. Problems always occur if the installer does not take precautions in the following areas: Wire Size Inadequate wire sizes can cause an excessive voltage drop, causing the compressor and fan motors to operate at undesirably low voltage rates. Duct Size Inadequate duct size, elbows, distributors or registers can restrict air flow. Duct Openings Duct Insulation - Improperly sealed duct sections can cause considerable loss in cooling capacity due to air leakages. - Inadequate duct insulationin attic space will cause heat gain in the system. Refrigerant Gtmrge - Unit is precharged, but should a change be necessary, it should be verified against the operating system pressures, temperatures, and current draws as specified in the catalog. These air conditioners have proven their reliability over several decades. Years of research, engineering and only the highestqualitycomponent parts and workmanshiphave gone intothese units to make them the most reliable in the industry. Before a model is released for production,it undergoes a;battery of tests in environmentaltest rooms with conditions of up to 120°F desert temperatures. = t -1- when installed inan unconditionedarea. Where the supply duct is exposed to the outdoor temperatures, vapor barrier material should be used. All duct work should be installed in accordance with ASHRAE or NAHB. It is very important that the ducts for a selfcontained system be properly sized, installed, sealed, and insulated for the best performance ofthe system. It is recommended that both the supply and the return duct be insulated (2") SC MODELS Model A B C D E F G H J K L 181F1 43 1/4 323/8 24 20 141/2 6 1 1 6_s 1112 21/2 245F2 49 1/4 33 3/4 30 21 14 1/2 6 7 1 63_ 11/2 21/2 305F2 49 1/4 33 3/4 30 21 14 1/2 6 7 1 1 63/8 63/8 11/2 11/2 21/2 21/2 1 I/2 21/2 365F1 49_/4-- 33 3/4 30 21 201/2 6 1 425F 485F 491/4 573/4 333/4 443/8 30 301/4 21 32 17 16114 93/8 10 1 lJ8 1 114 1 6_ 1 63/16 2 23/4 605F 573/4 44us 301/4 32 161/4 10 1 1/4 1 63/16 2 23/4 662A 573/4 443/8 341/4 _ 231/2 7 1 1 5 lJ8 1 3/4 23/4 "See Rg.2 -2- , I ..L Page 9 shows a typical wiring diagram for the various units.

These mounts are to help eliminate vibration and noise. Ground installationis basicallythe same for both self-contained units and split-system outdoor units. Locate the unit on a concrete slab or blocks not connected to the buildings foundation. Allow adequate clearance for service and air intake and discharge. The unit must be level in order to assure proper condensate drainage, and the gravityflow condensate line should be a minimum of 3/4 inch I.D. diameter and be properly graded. This system is a completely serf-contained cooling unitwith all components in one cabinet. It is shipped completely charged withthe proper amount of refrigerant. The unit is ready for operation after connecting duct work, condensate drain and power supply. An adhesive backed soft-foam weather strip or caulking must be attached on the horizontal channel batween the supply and return air openings as shown on page 5. A condensate =p"trap must be installed for every unit as shown also on page 5.

After allinsulating ofductwork and adjustments of air registers are complete, a temperature difference of 15° to 20° is considered satisfactory. START-UP If power to unit has been disconnected for any extended period of time, restore power twelve (12) hours prior to start-up procedure. 5. When the above Steps are completed, a check of voltage and amperage should be made of all motors. These readings should be within 10% of the performance ratings given for the spodfic ambients. COOUNG CYCLE CHECK-OUT PROCEDURE 1. With thermostat calling for cooling and set 10° below room temperature, engage disconnect switch(es) to start system. 6. Suction and discharge pressures should also be checked to ensure that they agree reasonably well with the pressures shown in the catalog for the prevailing ambient conditions. Also, a suction superheat ternperature of 20°F plus or minus 5°F is common for these units when the outdoor amblent is approximately 95°F. This shouldbe used as a gauge in determining that the system is not overcharged or has lost some of its charge. 2. Check the voltage at the compressor motor connections. If the voltage is 5% below or 10% above the rated voltage or there is a difference greater than 3% between phases, shut down the system and call the power company. A failure to do so may cause damage to the equipment. 3. After the unit is in operation, it will take about 30 minutes running time to Stabilize the system. 7. Finally, the thermostat should be checked out to assure proper operation. Literature packed with the thermostat and sub-base will provide information for this check out. 4. In order to check for a properly working system, it is recommended that a ther- trol. When the thermostat calls for "COOLING", current from the "R" terminal is switched on to the "Y" terminal causing the compressor contactor to be energized. The main contactor closes the contacts in the high voltage circuit. The completion of this circuit will start both the outdoor fan motor and the compressor. With the disconnect on "ON" position, voltage is supplied to the primary of the control transformer and crankcase heater. The control transformer reduces the voltage from 230 or 208 to 24 volts for the low voltage and the thermostat circuit. With a single-stage cool/ single-stage beaLthermostat set in the cooling position, current is supplied from one side of the 24 volt secondary of the controltransformer tothe"R"terminalof the thermostat.

Always let the thermostat control the operation of the system. Never try to =second guess" the thermostat, or tamper with it. Just set the thermostat at the comfort level desired AND LEAVE IT ALONE. If it gets too chilly, just turn the thermostat up a degree at a time untilthe desired level is achieved. Don't turn the thermostat back and forth. 3. Air conditioners cannot cool off a house as fast as a furnace heats it. It pulls the temperature down slowly. Therefore, do notturn on and expect immediate action. It may take a day or so to pull down a hot, moist house when the unit is first installed, especially after it has been =soaked"in 100110 ° ambient for days. . 4. Keep both the evaporator and condenser coil surfaces clean. Accumulation of dirt will restrict the air flow and reduce the Your new air conditioner compressor is equipped with a Permanent Split Capacitor motor. Therefore, ALWAYS WAIT AT LEAST THREE MINUTES AFTER SHUTTING UNIT OFF BEFORE TRYING TO RESTART. If the unit is started before the refdgerant pressures have a chance to balance, the compressor motor may tdp on its ovedoad, or, invery rare cases, blow a fuse. Under any normal operation, this will not happen. It is most likely to happen if a thermostat is chattering, or if the unit is started too quickly. Do not be alarmed if this happens. Just letthe pressures balance out and then start the unit. It is a good practice when there is a power outage, especially dudng severe thunder storms, to switchoff your unitat the thermostat until the electdcal power has been permanently restored. This could prolong the life of your compressor. IMPORTANT . performance of your unit. 5. Keep condensate drain lines clear and clean. All blower fan motors are factory lubricated and require no attention. The compressor is hermetically sealed, requiring no attention. 6. Your new air conditioner is mounted outdoors. Iti_ _-od practice to treat it just as you would your automobile if it was exposed to the elements constantly; an occasional coat ofwax will give added protection against the elements. - READ CAREFULLY Your new air conditioner contains a special compressor warming electrical circuit to keep the compressor warm dudng long off periods. Do not be alarmed ifthis creates a light =humming"sound while the unit is not running. The "hum" may or may not occur. Whenever the power has been disconnected from the unit for longer than twelve hours, be sure to turn the power back on twelve hours before starting the unit. This will give the compressor warming circuit a chance to operate and protect the compressor from damage. J -7- HOWTO GET THE MAXIMUM FROM YOUR PLEASURE _ AIR CONDmONER ture is about the same but there is discomfort. This is because the humidity is high. Indoors, the air should be beth cool and relatively dry for comfort. Therefore, the cooling unit has been designed to remove beth heat and moisture. In order that you may fully enjoy the comfort your Air Conditioner can bring you, an understanding of the basic principles involved are outlined in the following paragraphs. THERMOSTAT SETrlNG: HEATING LOAD: For cooling, a temperature of 75 to 78 degrees is preferred by most people. You may select a lower temperature setting if you wish and you will probably have that temperature a good portion ofthe time. But do not be disappointed and condemn the equipment if the temperature gets a few degrees warmer during hotweather. Set the thermostat at the temperature agreeable to the family and leave it there. Any residential cooling system is the reverse of a heating system. Family living habits that help the heating system hurt the cooling system. The heat pump, fumace, or boiler delivers heat into the rooms and the heat that is created within the house from electric lights, cooking, the TV set, etc. helps to heat the rooms therefore, that much less heat is required from the boiler, furnace, or heat pump. Do not be concerned if, in the evening, when the outside temperature drops belowthe inside temperature, your air conditioning system is stillrunning. The entire structure of your house has been soaking up heat from the sun all day long. After the sun has set there is still a tremendous amount of heat in the walls, ceiling, roof, furnishings, etc., that must be disposed of before the air conditioner stops running. Outdoor temperatures can drop rapidly after sundown, while the house and its furnishings continue to give off heat for several hours. Cooling is just the reverse. The cooling equipment removes heat and humidity. Any extra heat released into the rooms from these same sources will make the room air warmer and place an extra burden upon the equipment. Let's take the heat caused by cooking. For example, four top burners of a gas range can produce more heat than a three horsepower air conditioner can remove. It is much more practical and economical to ventilate this concentrate heat and moisture load than it is to dispose of it threugh your air conditioner. Here is a general rule. INDOOR BLOWER OPERATION Whenever you plan to have youroven or range top burners on for more than few minutes dudng hot weather, close off the kitchen from the rest of the house, open a window or outside door, and turn on your kitchen ventilator. To improve the efficiency ofthe unit, the blower is operated on atime delay. Depending on the outside ambient, the blower could delay starting up for 5 to 15 seconds even though the thermostat calls for cooling. When the thermostat is satisfied, the blower could keep on runningfor 1/2 to 1-1/2 minutes longer. Do not be alarmed if you do not hear-tim blower running immediately after the unit is switched You can also-effectively reduce the load on yourcoolingsystem by keeping windowshades, blinds,ordrapes closed or by installingawnings or canopies. on. Your unit is an Air Conditioner. It is producing cooled air. The cooling which is accomplished by means of remote controls, is completely automatic, and requires no attention after setting to the comfort level you desire. There are days when the temperature is relatively high, yet it is comfortable because the air is dry. This is because the relative humidity is low. There are other days when the temperaI* -8- CT3"- GOETTL AIR CONDITIONING, P.O. Box 52029 613360 Rev. 9/96 2.5M INC. • Phoenix, Arizona 85072-2029
