The reading must be within the minimums and maximums shown below for the operating voltage. Operating Voltages Operating Voltage Minimum Voltage Maximum Voltage 230/208 197 253 265 238 291 NOTE: 1. All 265 volt models must use subbase or hard wire kit. 2. Minimum branch circuit ampacity ratings conform to the National Electric Code.
PROPER INSTALLATION WALL SLEEVE INSTALLATION • If installed in a concrete or masonry wall, a lintel must be provided in the wall opening for support. Do not use the wall sleeve as a lintel. See Framing with Lintel Figure for a typical lintel construction. The wall sleeve must be installed before the air conditioner or heat pump chassis can be set in place. Read the instructions thoroughly before proceeding.

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 • Indoor/Outdoor Coil Thermistors- In the cooling mode, if the compressor is engaged continuously for 20 minutes and the Indoor Coil Thermistor is below 30 degrees the compressor is disengaged until the ICT rises above 45 degrees. The Outdoor Coil Thermistor senses coil temperature which correlates to outdoor air temperature. Heat pump operation can operate as low as 24°F outdoor temperature depending upon humidity conditions and/or the balance point of the system.

SERVICING Refer to the cooling and heater performance charts in this section for capacity test procedure. A step-by-step procedure for determining source of trouble, suggested method and normal values are provided in the Diagnosis Charts. Service operations requiring opening of the hermetically sealed refrigeration system should not be performed in the home. The unit must be taken to a well equipped shop where special equipment for evacuating, dehydrating, charging and testing is available.
SERVICING 1. Connect the vacuum pump, vacuum tight manifold set with high vacuum hoses, thermocouple vacuum gauge and charging cylinder. 2. Connect the low side line to the process tube of the compressor. 3. Connect the high side line to the process tube of liquid line strainer. NOTE: If either process tube is not long enough to receive the compression or flare fitting and still leave room for a pinch-off, swag the tube and braze in an extra length of tubing. 4.
SERVICING Place discharge air thermostat here E. Subtract temperature obtained in Step B from temperature obtained in Step A. The remainder temperature is used to calculate from the Cooling Range Chart. EXAMPLE: Assume a PTH15 unit is under test and the temperature readings indicated below were obtained. 1. Return air D.B. temperature: 80°F, Step A. 2. Discharge air D.B. temperature: 69°F, Step B. 3. Return air, wet and dry bulb temperature as recorded in Step C: Dry Bulb 80°F, Wet Bulb 75°F.
SERVICING Read to the right front the 75°F W.B. value in the PTH15 column and note the minimum and maximum wattage of 1460 - 1575. Since the wattage reading (1510) obtained in the test is within the prescribed range, the total power input in watts is considered to be normal. Electric Heat Test For the electric heat test, the following readings must be recorded after the unit is interconnected with a wattmeter or by recording the total amp draw to the unit.

SERVICING 1. Remove the motor leads from their respective connection points and capacitor (if applicable). Ground Test With no power and compressor leads removed: 2. Check the continuity between each of the motor leads. Set an ohmmeter on its highest scale. Touch one lead to the compressor body (clean point of contact, as a good connection is a must) and the other probe to each compressor terminal in turn. If a reading is obtained, then the compressor is grounded and must be replaced. 3.

Not all installations have the screws. Then remove the front. Do this by pulling the bottom corners out and lifting up. Since all single phase compressors are of the permanent split capacitor design the high and low side pressure must be approximately equal or the low torque compressor may not start.
SERVICING 6. Clean the end of the capillary tube and insert into the tube, it may be necessary to crimp tubing around the capillary tube, being careful not to damage the capillary tube. Insert the bottom of the filter drier into the condenser elbow, it may be necessary to heat slightly to get coupling to go into place. Brazing WARNING BRAZING REQUIRES HIGH TEMPERATURES.
