Certified in accordance with the Air-Source Unitary Air-conditioner Equipment certification program, which is based on ARI standard 210/240. In order to achieve ARI standard rating, the indoor fan time delay on the comfort control must be enabled. Rated in accordance with ARI standard 270. Calculated in accordance with Natl. Elec. Codes. Use only HACR circuit breakers or fuses. Standard Air - Dry Coil - Outdoor This value approximate. For more precise value see unit nameplate. Reference the outdoor unit ship-with literature for refrigerant piping length and lift guidelines. Reference the refrigerant piping software pub # 32-3312-xx or refrigerant piping application guide SSAPG006-xx for long line sets or specialty applications (xx denotes latest revision). The outdoor condensing units are factory charged with the system charge required for the outdoor condensing unit, ten (10) feet of tested connecting line, and the smallest rated indoor evaporative coil match. Always verify proper system charge via subcooling (TXV/EEV) or superheat (fixed orifice) per the unit nameplate. This value shown for compressor RLA on the unit nameplate and on this specification sheet is used to compute minimum branch circuit ampacity and max. fuse size. The value shown is the branch circuit selection current. No means no start components. Yes means quick start kit components. PTC means positive temperature coefficient starter. Optional kit shown. !

The following charging methods are therefore prescribed for systems with indoor TXVs. 1. Subcooling (in the cooling mode) is the only recommended method of charging above 55°F ambient temperatures. 60 195 198 201 204 208 211 215 65 211 215 218 222 225 229 232 70 229 232 236 240 243 247 251 75 247 251 255 259 263 267 271 80 267 271 275 279 283 287 291 85 287 291 296 300 304 309 313 90 309 313 318 322 327 331 336 2. For best results - the indoor temperature should be kept between 70°F to 80°F. Add system heat if needed. 3. At start-up, or whenever charge is removed or added, the system must be operated for a minimum twenty (20) minutes to stabilize before accurate measurements can be made. 4. Measure Liquid Line Temperature and Refrigerant Pressure at service valves. 95 331 336 341 346 351 355 360 100 355 360 365 370 376 381 386 105 381 386 391 396 402 407 413 110 407 413 418 424 429 435 441 115 435 441 446 452 458 464 470 120 464 470 476 482 488 495 501 125 495 501 507 514 520 527 533 5. Determine total refrigerant line length, and height (lift) if indoor section is above Refer to Service Facts or the condenser. Use the Subcool Charging Chart Corrections Table to Installer's Guide for charging method. calculate any additional subcooling required for your specific application. From Dwg. D154557P01 Rev. 3 6. Determine the Design Subcooling from the unit nameplate or Service Facts. Add any additional amount of subcooling calculated in Step 5 to the Design Subcooling to arrive at the final subcooling value. 7. Locate this value in the appropriate column of the R-410-A Refrigerant Charging Chart. Locate your liquid line temperature in the left column of the chart, and the intersecting liquid line pressure under your calculated subcooling value column. Add refrigerant to raise the pressure to match the chart, or remove refrigerant to lower the pressure. Again, wait twenty (20) minutes for the system c onditions to stabilize before adjusting charge again. 8. When system is correctly charged, you can refer to System Pressure Curves (in Service Facts) to verify typical performance. 4 4TTX8036A-SF-1K-EN REFRIGERATION CIRCUITS Cooling Refrigeration Cycle 4TTX8036A-SF-1K-EN Printed from D158948 5 Compressor fails to start Contactor check TROUBLESHOOTING Is contactor energized?
