Only trained, qualified installers and service mechanics should install, start-up, and selwice this equipment. Do not bury more than 36 in. of refrigerant pipe in the _ound. If any section of pipe is buried, there must be a 6 in. vertical rise to the valve connections on the outdoor units. If more than the recomlnended length is buried, refrigerant may mLm'ateto the cooler buried section during extended periods of systeln shutdown. This causes refiiger-ant slugging and could possibly damage the compressor at start-up. Untrained personnel can perform basic maintenance functions such as cleaning coils. All other operations should be performed by trained selwice personnel. When working on the equipment, observe precautions in the literature and on tags, stickers, and labels attached to the equipment. Follow all safety codes. Wear safety glasses and work gloves. Keep quenching cloth and fire extinmJisher nearby when brazing. Use care in handling, rigging, and setting bulky equipment. Before installing or servicing system, always turn offmain power to system and install lockout tag on disconnect. There may be more than one disconnect switch. Electrical shock can cause personal injury.

Place remote control into remote control Mounting Bracket. 4. For remote control operation, refer to the unit O,a_er's Manual. MAKE REFRIGERANT PIPING CONNECTIONS (OUTDOOR UNIT) To connect the refrigerant lines: Use only "L" type sealed, dehydrated copper reliigerant tubing. No other type of tubing may be used. Use of other types of tubing will void the lnanufacturer's warranty. Do not open service valves or remove protective caps from tubing ends until all the connections are made. Bend robing with special bending tools to avoid the forlnation of sharp bends. Take care to avoid kinks or flattening of the tubing. Keep the tubing tree of dirt, sand, moisture, and other contaminants to avoid damaging the refrigerant system. Avoid sags in the suction line to prevent the formation ofoil traps. .... REMOTE I [ CONTROL REMOTE Mounting / CONTROL MOUNTING Fig. 10 m Attach Insulate each tube with 3/8-in. walled thermal pipe insulation. Inserting the tubing into the insulation before making the connections will save time and improve installation The suction and mixed-phase lines should never come in direct contact.

Conceal the tubing where possible. To avoid the possibility of electric shock, bet\_re performing any cleaning and maintenance operations, always turn offpower to the system by pressing the ON/OFF button on the remote control and turn off the separate disconnect switch located near the unit. If the indoor unit is on a separate switch, be sure to turn this disconnect off as well. 2. Make sure that the drainage tube slopes downward along its entire length. 3. Ensure all tubing and connections are properly insulated. 4. Fasten robes to the outside wall. 5. Seal the hole through which the cables and tubing pass. 6. Connect the air conditioner to the power source and turn it on. 7. Do not wash filter in water over 120°F (to avoid shrinkage). Do not expose filter to fire (to avoid fire damage). Do not expose tilter to direct sunlight. Clean tilter more frequently when air is extremely dirty. Check all air conditioner operating modes. Refer to Owner's Manual for operating details. INDOOR UNIT 1. Do all the remote controller buttons function properly? 2. Do the display panel lights work properly? 3. Does the air deflection louver function properly? 4. Does the drainage work? OUTDOOR Do not attempt to clean or seraqce components in controlbox. To (.'lean the Indoor Unit Front Panel if the front panel of the unit becomes dirty or smudged, wipe the out-side of the panel with a soft dry cloth. Use a mild liquid deter-gent and wipe offcarefulty with a dry cloth. UNIT 1. Are there unusual noises or vibrations during operation? 2. Is noise, drain water or airflow from the unit likely to disturb the neighbors? 3. Are there aW gas leaks? To (.'lean Indoor (,'oil To clean the coil, remove indoor unit front panel and vacumn the coil tins, using care not to bend or damage tins. LUBRICATION The indoor-l_an, automatic air sweep, and the outdoor-fan motors are factory lubricated and require no oiling. EXPLAIN THE FOLLOWING ITEMS TO THE CUSTOMER, WITH THE AID OF THE OWNER'S MANUAL: 1. How to turn the air conditioner on and off; selecting cooling, heating and other operating modes; setting a desired temperature; setting the timer to automatically start and stop air conditioner operation; and the other features of the remote controller and display panel. 2. How to remove and clean the air filter. 3. How to set the air deflection louver. 4. Explain care and maintenance. 5. Present the Owner's Manual and installation instructions to the customer. Air Filters for Indoor Units Operating your system with dirty air filters may damage the indoor unit and, in addition, can cause reduced perfor-mance, intermittent system operation, frost build up on the indoor coil, and blown fuses. Inspect and clean or replace the air filters monthly. TO REMOVE AIR FILTERS Open the unit's front panel by lifting the lower part and pulling it gently outward and upward. Pull out the filters. CARE AND MAINTENANCE TO CLEAN OR REPLACE FILTERS Filters can be vac-uumed or washed in warm water. Shake tilter to remove any excess water, and replace it back. If the filter has begun to break do,am or is tom, replace it. Replacement tilters are available through a local dealer. The t\_ltowing may be pert\_rmed by the equipment owner. Outdoor Units Before per forming recolrnnended maintenance, be sure unit main power switch is tamed off Failure to do so may result in electric shock or injury from rotating tan blade. SERVICE The following should be performed by a qualified service technician. CLEANING COILS Coil should be washed out with water or blown out with compressed air. Clean coil annually or as required by location and outdoor air conditions. Inspect coil monthly and clean as required. Fins are not continuous through coil sections. Dirt and debris may pass through first section, become trapped between the row of fins and restrict outdoor unit airflow. Use a flashlight to determine if dirt or debris has collected between coil sections. Clean coil as follows: (,'lean Condensate Drains Clean all drains and drain pans at the start of each cooling season. Check the flow by pouring water into the drain. (.'lean or Replace Drain Pan The drain pan should only be cleaned or replaced by a qualified selaqce technician. 1. Place a plastic sheet on the floor to catch any water that may spill from the drain pan. Turn offunit power and install lockout tag. 2. Using a garden hose or other suitable equipment, flush coil from the outside to remove dirt. Be sure to flush all dirt and debris fiom drain holes in base of unit. Fan motors are waterproof. 1. 2. 3. 17 Remove the intake _itte and distribution assembly. Remove the condensate water in the drain pan by letting water drain into a 3-gallon bucket.
