550.38-N1Y ® GENERAL Installer should pay particular attention to the words: NOTE, CAUTION and WARNING. This instruction covers the installation of the following Stellar air conditioning units. NOTES are intended to clarify or make the installation easier. NOMENCLATURE CAUTIONS are given to prevent equipment damage. H 4 DB 030 S 06 Product Category WARNINGS are given to alert the installer that personal injury and/or equipment damage may result if installation procedures are not handled properly.

After holding charge is completely discharged, loosen and remove the liquid line fitting from the orifice distributor assembly. Note that the fitting has right hand threads. Remove the orifice from the distributor body using a small diameter wire or paper clip. Orifice is not used when the TXV assembly is installed.

550.38-N1Y 4. ® The vapor line must be insulated with a minimum of 1/2" foam rubber insulation (Arm-A-Flex or equivalent). Liquid lines that will be exposed to direct sunlight and/or high temperatures must also be insulated. Dry nitrogen should always be supplied through the tubing while it is being brazed, because the temperature required is high enough to cause oxidation of the copper unless an inert atmosphere is provided. The flow of dry nitrogen should continue until the joint has cooled.

550.38-N1Y ® 7. Replace the schrader cores in the liquid and vapor valves. 8. Evacuate the vapor line, evaporator and the liquid line, to 500 microns or less. 9. Leak test all refrigerant piping connections including the service port flare caps to be sure they are leak tight. DO NOT OVERTIGHTEN (between 40 and 60 inch - lbs. maximum). NOTE: Do not use the system refrigerant in the outdoor unit to purge or leak test. 10. Replace caps on service ports.

550.38-N1Y ® The “TOTAL SYSTEM CHARGE” must be permanently stamped on the unit data plate. Total system charge is determined as follows: 1. Determine outdoor unit charge from tabular data sheet. 2. Determine indoor coil adjustment from tabular data sheet. 3. Calculate the line charge using the Tabular Data Sheet. a. Calculate total length of pre-charged lines for quick connect units. b. Calculate over 15 feet of sweat lines for sweat connect units.
