Panel Installation REFRIGERANT CHARGING WARNING: This split system heat pump is shipped charged with R410A refrigerant and ready for installation. If repairs make it necessary for evacuation and charging, it should only be attempted by qualified trained personnel thoroughly familiar with this equipment. Under no circumstances should the owner attempt to install and/or service this equipment. Failure to comply with this warning could result in property damage, personal injury, or death. After refrigerant line connections are completed, it is required that you leak check and evacuate the indoor section and all line connections (using proper methods) before finalizing the full system refrigerant charge. • To achieve rated capacity and efficiency, the compressor must be exposed to refrigerant for at least 24 hours prior to running and then the compressor must be run for a minimum of 12 hours. • Refer to the Quick Reference Data sheet for additional charging information. Outdoor units with non-AHRI listed indoor coils are not recommended and deviations from rated airflows or non-listed combinations may require modification to the expansion device and refrigerant charging procedures for proper and efficient system operation. • The refrigerant charge can be checked and adjusted through the service ports provided external to the outdoor unit. Use only gage line sets which have a “Schrader” depression device present to actuate the valve. A common suction port for heating mode charging is included and located on the compressor access panel above the outdoor unit service valves. • A high-pressure switch is factory-installed and located in the compressor discharge line internal to the outdoor unit. The switch is designed to de-energize the system when very high pressures occur during abnormal conditions. Under normal conditions, the switch is closed. If the discharge pressure rises above 575 psig, then the switch will open and de-energize the outdoor unit. The switch will close again once the liquid pressure decreases to 460 psig. Please note that the switch interrupts the thermostat inputs to the unit. When the switch opens and then closes, there will be a 5 minute short cycling delay before the outdoor unit will energize. • A low-pressure switch is factory installed (certain models) and located internally on the suction line of the outdoor unit. The switch is designed to protect the compressor from a loss of charge by interrupting the thermostat inputs to the unit. If the suction pressure falls below 20 psig, the switch will open and de-energize the outdoor unit. The switch will close again when the suction pressure increases above 35 psig. When the switch opens and then closes, there is a 3 minute short cycling delay before the outdoor unit will energize. Under normal conditions the switch is closed. Charging the Unit in AC mode If the outdoor temperature is 65 degrees F or higher: After completing the refrigerant line connections, leak checking the system, and evacuating the indoor section and all line connections (using proper methods), perform the following steps: 1. Determine the recommended charge addition (if applicable) for the system being installed. This information is in the unit’s QRD (Quick Reference Data sheet). 2. Calculate the amount of additional refrigerant needed for the line set length of the actual installation. This information is on the first page of the unit’s QRD (Quick Reference Data sheet). 3. Weigh in the additional charge amounts determined by step 1 and 2 above. 4. Adjust the charge to match the superheat (for fixed orifice systems) or subcooling (for TXV systems). There are three different resources for doing this: a.) The chargecalculator.com website. This will walk you through the charging process step by step. b.) The charging tables on the inside of the outdoor unit’s electrical box cover panel. These tables provide superheat targets for fixed orifice systems and subcooling targets for TXV systems. The system should be charged so that the measured superheat/ subcooling are within 1 degree F of the target listed in the table. For fixed orifice systems: • If your measured superheat at the suction valve is LESS THAN the recommended superheat value in the table then REMOVE refrigerant. • If your measured superheat at the suction valve is GREATER THAN the recommended superheat value in the table then ADD refrigerant. For TXV systems: • If your measured subcooling at the liquid valve is LESS THAN the recommended subcooling value in the table then ADD refrigerant. • If your measured subcooling at the liquid valve is GREATER THAN the recommended subcooling value in the table then REMOVE refrigerant. c.) The charging tables in the Supplemental Charging Information, can be found online in the literature library. The tables can also be accessed by scanning the QR code on the unit’s electrical panel. The pressures listed in these tables are for reference only and are to be used in troubleshooting a system. The system should be charged to match the superheat or subcooling targets as previously noted and not to match the system pressures. Follow the same procedure described in 4b above. If the outdoor temperature is between 35 degrees F and 65 degrees F: After completing the refrigerant line connections, leak checking the system, and evacuating the indoor section and all line connections (using proper methods), perform the following steps: 1. Determine the recommended charge addition (if applicable) for the system being installed. This information is in the unit’s QRD (Quick Reference Data sheet). 2. Calculate the amount of additional refrigerant needed for the line set length of the actual installation. This information 9 superheat/subcooling are within 1 degree F of the target listed in the table. For fixed orifice systems: • If your measured superheat at the suction valve is LESS THAN the recommended superheat value in the table then REMOVE refrigerant. • If your measured superheat at the suction valve is GREATER THAN the recommended superheat value in the table then ADD refrigerant. For TXV systems: NOTE: One half of the unit should be covered corner to corner. Figure 8. Blocked Off Outdoor Fan Discharge is on the first page of the unit’s QRD (Quick Reference Data sheet). 3. Weigh in the additional charge amounts determined by step 1 and 2 above. 4. Block off the discharge of the outdoor fan. NOTE: One half of the unit should be covered corner to corner as shown in Figure 8 (page 10). 5. With the unit in cooling mode, Adjust the charge to match the superheat (for fixed orifice systems) or subcooling (for TXV systems). There are two different resources for doing this: a.) The chargecalculator.com website. This will walk you through the charging process step by step. b.) The low ambient charging tables on the inside of the outdoor unit’s electrical box cover panel. These tables provide superheat targets for fixed orifice systems and subcooling targets for TXV systems. The system should be charged so that the measured 10 • If your measured subcooling at the liquid valve is LESS THAN the recommended subcooling value in the table then ADD refrigerant. • If your measured subcooling at the liquid valve is GREATER THAN the recommended subcooling value in the table then REMOVE refrigerant If the outdoor temperature is below 35 degrees F: After completing the refrigerant line connections, leak checking the system, and evacuating the indoor section and all line connections (using proper methods), perform the following steps: 1.
