Unit Charge (Lbs. - Oz.) 5
5. The Unit Charge is correct for the outdoor unit, smallest matched indoor unit, and 15 feet of refrigerant tubing. For tubing lengths other than 15 feet, add or subtract the amount of refrigerant, using the difference in actual lineset length (not the equivalent length) multiplied by the per foot value.
CHARGING PROCEDURES:1. Determine outdoor unit factory charge from Tabular Data Sheet.2. Determine indoor coil adjustment (if any) from Tabular Data Sheet.3. Calculate the additional charge for refrigerant piping using this Tabular Data Sheet if line length is greater than 15 feet (4.6 m).4. Total system charge = item 1 + item 2 + item 3.5. The manifold gauge set is already installed on the unit for evacuation and charging. Use these gauges to initially charge the system using system pressures and
subcooling. Before charging put the equipment into “Service Mode” at the outdoor control. You will find the charging information printed on the bottom of the unit data tag. More charging information is available in the “Service Data Application Guide”, available online. For subsequent annual maintenance visits the charge verification display can be used to quickly check overall system condition and the system charge without attaching a separate manifold gauge set or temperature sensors.
6. Permanently mark the unit data plate with the total amount of refrigerant in the system.

NOTICEInverter Temperature ProtectionIf excessive inverter temperatures are sensed, the compressor speed/ capacity is reduced until an acceptable condition is reached.When the inverter temperature returns to an acceptable level, thesystem returns to normal operation.Over / Under Current Protection: If a low or high Current Conditionis sensed, the compressor speed / capacity is reduced until anacceptable current level is reached.When the system reaches an acceptable current level, the compres-sor and fan return to normal operating conditions.Over / Under Voltage Protection: If a low or high supply VoltageCondition is experienced (below 187 VAC or above 265 VAC), thecompressor speed / capacity is automatically reduced until an accept-able voltage level is sensed.When an acceptable voltage level is sensed, the system automati-cally returns to a normal state of operation.High Altitude Protection: If the unit is installed in Altitudes of 6,500ft / 2,000 m above sea level or higher, the compressor and outdoorfan reduce speeds to protect the system. It is not recommendedthese units be installed at altitudes greater than 6,500 ft / 2,000 mabove sea level.Low Ambient ProtectionCooling Mode: The unit automatically adjusts to maintain coolingoperation in outdoor ambient conditions down to 35° F (2° C). Theunit reduces capacity and Low Ambient Protection (cooling mode) orcycles off if asked to provide cooling when the outdoor temperature isat or below these conditions.Heating Mode: The unit provides compressor heat down to an out-door ambient temperature of -5° F (-21° C). As the outdoor ambienttemperature reduces, available heat reduces for all air source heatpumps. Make sure the balance point and auxiliary heat are appropri-ately set and sized for the application of the heat pump.

UNIT OPERATIONDEFROST MODEThe defrost mode is equivalent to the cooling mode except thatthe outdoor fan motor is de-energized.If the call for heating is removed from the control during thedefrost cycle, the system will terminate the defrost cycle. Thesystem will also stop the “Defrost Cycle Timer” but not reset it.When the system receives another call for compressor heating,it will restart the defrost cycle and the “Defrost Cycle Timer” atthe point at which the call for heating was removed; if the condi-tions requiring a defrost still remain (coil temperature is below35°F).The system will remember what compressor speed and wherein the operational algorithm the system is being operated beforeinitiating a defrost. The system will run the “Defrost CompressorSpeed” for the given tonnage. The system will run the “Cali-brated Compressor Speed” during calibration.
• The system will do the following to initiate a defrost cycle.• Record the Outdoor EEV Setpoint.• Record the Calibrated Compressor Speed and where in the
operational algorithm the system is.• The Suction Pressure Fault is ignored during defrost unless
the Absolute Trip value is < 5psi., then the fault is recognizedas active.
• Communicate proper speed of compressor “Defrost Com-pressor Speed”.
• Communicate proper speed of ID CFM for the “Defrost ID Air-flow”.
• Communicate the Outdoor Fan speed to 0.• Energize the reversing valve.• Fully open the Outdoor EEV.• Communicate proper Indoor EEV Setpoint “ID EEV Setpoint”.• Begin the “Defrost Cycle Timer”.• Communicate the W1OUT for auxiliary heat.
