* Outdoor section/indoor section combination tested in accordance with DOE test procedure for electric air conditioners.
† In most cases, only 1 method should be used to achieve TDR function. Using more than 1 method in a system may cause degradation in performance. Use either the
accessory Time-Delay Relay KAATD0101TDR or a furnace equipped with TDR. All Bryant furnaces are equipped with TDR except for the 394HAD.
‡ Based on computer simulation. TXV must be R-410A compatible and hard shutoff type.

TDR—Time-Delay Relay
TXV—Thermostatic Expansion Valve
NOTES: 1. Ratings are net values reflecting the effects of circulating fan heat. Supplemental electric heat is not included.
2. Determine actual CFM values obtainable for your system by referring to fan performance data in fan coil or furnace coil literature.
3. Do not apply with capillary tube coils as performance and reliability are significantly affected.

* Tube diameters are for lengths up to 50 ft. For tubing lengths greater than 50 ft, consult the Application Guideline and Service Manual for Residential Split-System Air
Conditioners and Heat Pumps Using R-410A Refrigerant.
NOTE: Refrigerant tubes and indoor coils must be evacuated to 500 microns to minimize contamination and moisture in the system.
