MAINTENANCE NOTE: The compressor does not require maintenance. It is hermetically sealed, permanently lubricated. The following procedure is used to remove the intake filter: 1. Open the intake grille by grasping the top intake louver. 2. Pull the intake grille open. WARNING 3. Slide filter upward and remove. 4. Clean filter with vacuum or with running water. Reverse this procedure to reinstall the filter.
MAINTENANCE Basepan and Condenser Coil WARNING DO NOT USE COMMERCIAL GRADE COIL CLEANERS. SOME OF THESE CLEANERS MAY CONTAIN ETHYLENE DIAMINE TETRACETIC AICD (EDTA) WHICH CAN SHORTEN THE LIFE OF THE CONDENSER COIL. Vent - (Left Side Unit) Cabinet Front The cabinet front and discharge air grille can be cleaned with a water dampened cloth . Under no circumstances should hydrocarbon-based cleaners (e.g. acetone, benzene, naphtha gasoline, etc.) be used to clean the front or air grilles.
MAINTENANCE CLEARANCE CHECK Air Sounds Clearances around the unit should also be checked to make sure that the intake air and discharge air paths have not become blocked or restricted. A minimum of eight inches clearance is needed from unit to furniture, beds, or other objects for proper operation. Restricted discharge or intake air will reduce the units operational performance. In severe airflow restrictions damage can occur to unit components such as the compressor, electric heater or fan motor.
OPERATIONS SEQUENCE OF OPERATION Cooling Mode Set the thermostat to the desired temperature then set the mode switch to high or low cool. The fan motor will start first then the compressor will start approximately 10 seconds later. When the room temperature has reached the desired temperature the compressor will shut off and the fan will continue to run for 30 seconds then shut off.
OPERATIONS • Sample Before Start - The SBS routine is used in the cooling mode. This routine runs the unit fan on low speed for up to 120 seconds. The sample fan is aborted if compressor demand is detected. To avoid unnecessary sampling the period between samples will be based on specific room conditions. The default sample before start period after a power up is 5 minutes. The period is corrected every time a sample run is completed without a compressor demand.
OPERATIONS • If already in Diagnostic Status Report mode, press the • If already in Diagnostic Status Report mode, press the Fan Speed key. The display will show the temperature of the desired set point, SP; the temperature at the wireless thermostat, rL; the indoor ambient temperature behind the filter, IA; the indoor coil temperature, IC; the indoor discharge air temperature, Id; the outdoor coil temperature, OC; the outdoor ambient temperature, OA; and the spare probe temperature, IH.

SERVICING REFRIGERATION SYSTEM SERVICE WARNING WARNING BRAZING REQUIRES HIGH TEMPERATURES. TAKE PRECAUTION TO PROTECT AGAINST PERSONAL INJURY OR PROPERTY DAMAGE. TO AVOID THE RISK OF FIRE, THE REFRIGERATION SYSTEM MUST BE KEPT FREE FROM CONTAMINATION DUE TO THE PRESENCE OF AIR. FOLLOW THESE INSTRUCTIONS EXACTLY.
SERVICING Evacuation WARNING TO PREVENT SEVERE BURNS. DO NOT ALLOW THE SLUDGE OR OIL TO CONTACT THE SKIN. IMPORTANT NOTE: Effective July 1,1992. Before opening any refrigerant system it is the responsibility of the service technician to capture the refrigerant for safe disposal. This is the most important part of the entire service procedure.
SERVICING WARNING NEVER TEST OPERATION WITHOUT THE UNIT IN THE WALL SLEEVE. A SERIOUS CHANGE IN DESIGN SPECIFICATIONS FOR AIR MOVEMENT THROUGH THE EVAPORATOR AND CONDENSER COMPARTMENTS, CAUSING THE FAN MOTOR TO OVER HEAT AND THE REFRIGERATION SYSTEM TO BECOME UNBALANCED WILL OCCUR WHEN THE UNIT IS NOT INSTALLED IN THE WALL SLEEVE. Efficient operation is dependent on a balanced system.
SERVICING Calculating Procedure 1. Locate the outdoor temperature obtained in first column of Total Power Consumption Cooling Chart. 2. Locate in second column the return air wet bulb temperature obtained in Step C. 3. The total watts input should come between minimum and maximum values indicated for each model. EXAMPLE: Assume that a PTH15 is again under test. Proceed as follows and observe test readings as simultaneously as possible. 1. Outdoor dry bulb temperature reading - 95°F. 2.
