Check the unit rating plate to confirm specifications are as ordered. Location of Unit Refer to Figure 1 for installation clearances. General Read this entire instruction manual, as well as the instructions supplied in separate equipment, before starting the installation. Observe and follow all warnings, cautions, instructional labels, and tags. Failure to comply with these instructions could result in an unsafe condition and/or premature component failure. These instructions are intended as a general guide only for use by quali

If more than 50' line set is required, contact Technical Services at 1-800-448- 5872. Table 2 shows the diameters for line sets up to 100' although vertical lift applications and trapping requirements need to be reviewed with Technical Services for line sets over 50'. Installing Refrigerant Line During the installation of an air conditioning system, it is important to properly isolate the refrigerant line to prevent unnecessary vibration. Line set

Wrap a wet cloth around the valve body and copper tube stub to protect it from heat damage. 7. Braze the line set to the service valve. Quench the joints with water or a wet cloth to prevent heat damage to the valve core and opening port. The tube end must stay bottomed in the fitting during final assembly to ensure proper seating, sealing, and rigidity. Brazing Connection Procedure 1. Install a thermal expansion valve kit (sold separately) that is approved for use with R410A refrigerant in the liqu

Required Equipment The following equipment is needed to flush the existing line set and indoor coil (see Figure 8): Two clean R22 recovery bottles, an oil-less recovery machine with a “pump down” feature, and two sets of gauges (one for use with R22 and one for use with R410A). Flushing Procedure IMPORTANT: The line set and/or indoor coil must be flushed with at least the same amount of refrigerant that previously charged the system. Check the charge in the flushing cylinder before flush

Refer to the gauges after shutdown to confirm that the valves are not allowing refrigerant to flow back into the low side of the system. Disconnect the liquid and suction lines from the existing outdoor unit. 2. Remove the existing outdoor unit. Set the new R410A unit and follow the brazing connection procedure outlined previously on this page to make line set connections. Do not install the R410A thermal expansion valve at this time. 3. Make low voltage and line voltage connections to the new outdoor unit. Do not turn on po

A service port cap protects the Schrader valve from contamination and serves as the primary seal. Leak Testing After the line set has been connected to the indoor and outdoor units, the line set connections and indoor unit must be checked for leaks. Using an Electronic Leak Detector 1. Connect the high pressure hose of the manifold gauge set to the suction valve service port. (Normally the high pressure hose is connected to the liquid line port; however, connecting it to the suction ports helps to protect the mani

Open the manifold gauge valves to release the nitrogen from the line set and indoor unit. 8. Reconnect the manifold gauge to the vacuum pump, turn the pump on, and continue to evacuate the line set and indoor unit until 500 microns is maintained within a 20-minute period after shutting off the vacuum pump and closing the manifold gauge valves. 9. When the requirements above have been met, disconnect the manifold hose from the vacuum pump. Open the service valves to break the vacuum in the line set and indoor unit.

If the system is void of refrigerant, clean the system using the procedure described below. 1. Use dry nitrogen to pressurize the system and check for leaks. Repair leaks, if possible. 2. Evacuate the system to remove as much of the moisture as possible. 3. Use dry nitrogen to break the vacuum. 4. Evacuate the system again. 5. Weigh the appropriate amount of R410A refrigerant (listed on unit nameplate) into the system. 6. Monitor the system to determine the amount of moisture remaining in the oil. Use a test kit to verify that

When the thermostat blower switch is moved to the ON position, the indoor blower operates continuously. Maintenance and service must be performed by a qualified installer or service agency. At the beginning of each cooling season, the system should be checked as follows: 1. Clean and inspect condenser coil. Coil may be flushed with a water hose. Be sure the power is off before using water to clean the coil. 2. Outdoor fan motor is pre-lubricated and sealed. No further lubrication is needed. 3. Visually inspect connecting lines and coils for evidence
