REFRIGERANT TO ADD AT LINE TYPE SPECIFIED ADDITIONAL Note: The nameplate charge value represents LENGTH the amount of refrigerant shipped in the outdoor Suction Liquid Tonnage 20 ft 30 ft 40 ft 50 ft 60 ft unit and is compatible with 15 feet of AHRI rated Line Line refrigerant lines and the smallest AHRI rated 1.5 Ton 5/8" 3/8" 3 oz 8 oz 14 oz 20 oz 25 oz coil. 2 Ton 5/8" 3/8" 3 oz 8 oz 14 oz 20 oz 25 oz Using Table 14.3, find the charge associated with the additional length of tubing above 15 ft. 2.5 - 3.5 Ton 3/4" 3/8" 3 oz 9 oz 15 oz 21 oz 27 oz and record it below. 4 Ton 7/8" 3/8" 3 oz 9 oz 16 oz 22 oz 28 oz Namplate charge = ____________ Oz. 5 Ton 1-1/8" 3/8" 4 oz 11 oz 18 oz 25 oz 32 oz Charge adder = ______________ Oz. (from Table 14.2) 11-BC26D1-9-EN 21 STEP 2 - Stabilize the system by operating for a minimum of 20 minutes. At startup, or whenever charge is removed or added, the system must be operated for a mini- 20 MIN. mum of 20 minutes to stabilize before accurate measurements can be made. STEP 3 - Check the liquid line temperature and liquid gage pressure to obtain a minimum of 10º subcooling in heating mode. Measured Liquid Line Temp = __________ º F Liquid Gage Pressure = __________ PSIG STEP 4 - Add charge if a minimum of 10º sub- cooling is not obtained with the namplate charge plus additional charge previously added. STEP 5 - Return to site for adjustment. Important: Return in the spring or summer to accurately charge the system in the cooling mode with outdoor ambient above 55º F. Section 15. Checkout Procedures and Troubleshooting 15.1 Operational And Checkout Procedures Final phases of this installation are the unit Operational and Checkout Procedures.
