* 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.

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.
* TXV must be installed when indoor coil is not equipped with an R-410A approved TXV. TXV listed is for any approved coil
combination. All TXVs are R-410A specific hard shutoff.

* Permissible limits of the voltage range at which unit will operate satisfactorily. Operation outside these limits may result in unit failure.
† If other than uncoated (non-plated), 60° or 75°C(140° or 167°F) insulation, copper wire(solid wire for 10 AWG andsmaller, stranded wire for largerthan 10 AWG) is used,
consult applicable tables of the NEC (ANSI/NFPA 70).
If wire isapplied at ambient greater than 30°C (86°F), consult Table310-16 of the NEC (ANSI/NFPA 70). The ampacity ofnonmetallic-sheathed cable (NM), trade name
ROMEX, shall be that of 60°C (140°F) conductors, per the NEC (ANSI/NFPA 70) Article 336-30.
‡ Length shown is as measured 1 way along the wire path between the unit and the service panel for a voltage drop not to exceed 2 percent.
** Time-delay fuse or circuit breaker.
†† The factory refrigerant charge is for 15 ft of interconnecting tubing. For tubing lengths other 15 ft, refer to the Long-Line Application Guideline and Service Manual for
Residential Split-System Air Conditioners and Heat Pumps using R-410A.
‡‡ Use with low-ambient pressure switch.
*** Fan motor with ball bearings required.
TBD—To Be Determined
NOTE: Copper wire must be used from service disconnect to unit. All motors/compressors contain internal overload protection.

R-410A—QUICK REFERENCE GUIDE
• R-410A refrigerant operates at 50-70 percent higher pressures than R-22. Be sure that servicing equipment and replacement
components are designed to operate with R-410A.
• R-410A refrigerant cylinders are rose colored.
• R-410A refrigerant cylinders have a dip tube which allows liquid to flow out of cylinder in upright position.
• Recovery cylinder service pressure rating must be 400 psig, DOT 4BA400 or DOT BW400.
• R-410A systems should be charged with liquid refrigerant. Use a commercial type metering device in the manifold hose.
• Manifold sets should be 700 psig high side and 180 psig low side with 550 psig low-side retard.
• Use hoses with 700 psig service pressure rating.
• Leak detectors should be designed to detect HFC refrigerant.
• R-410A, as with other HFCs, is only compatible with POE oils.
• Vacuum pumps will not remove moisture from oil.
• Do not use liquid-line filter driers with rated working pressures less than 600 psig.
• Do not install a suction-line filter drier in liquid line.
• POE oils absorb moisture rapidly. Do not expose oil to atmosphere.
• POE oils may cause damage to certain plastics and roofing materials.
• Wrap all filter driers and service valves with wet cloth when brazing.
• A liquid-line filter drier is required on every unit.
• Do not use an R-22 TXV.
• If indoor unit is equipped with an R-22 TXV, it must be changed to an R-410A TXV.
• Never open system to atmosphere while it is under a vacuum.
• When system must be opened for service, break vacuum with dry nitrogen prior to opening to atmosphere.
• Always replace filter drier after opening system for service.
• Do not vent R-410A into the atmosphere.
• Do not use capillary tube coils.
• Observe all warnings, cautions, and bold text.

SYSTEM DESIGN
1. Intended for outdoor installation with free air inlet and outlet. Outdoor fan external static pressure available is less than 0.01-in. wc.
2. Minimum outdoor operating air temperature without low-ambient operation accessory is 55°F (12.8°C).
3. Maximum outdoor operating air temperature is 125°F (51.7°C)
4. For reliable operation, unit should be level in all horizontal planes.
5. Maximum elevation of indoor coil above or below base of outdoor unit is: indoor coil above = 30 ft; indoor coil below = 30 ft. (See items
6 and 7 following.)
6. For interconnecting tubing lengths greater than 50 ft, consult the Residential Split-System Application Guideline and Service Manual for
Air Conditioners and Heat Pumps using R-410A Refrigerant.
7. If ANY refrigerant tubing is buried, provide a minimum 6-in. vertical rise to the valve connections at the unit. Refrigerant tubing lengths
up to 36 in. may be buried without further considerations. For buried refrigerant tubing lengths greater than 36 in., consult the Residential
Split-System Buried-Line Application Guideline.
8. Use only copper wire for electric connection at unit. Aluminum and clad aluminum are not acceptable for the type of connector provided.
9. Mixmatches of indoor coil capacity of more than 2 sizes larger than outdoor unit capacity may result in inadequate indoor comfort.
10. Do not apply capillary tube indoor coils to these units.
11. Factory-supplied filter drier must be installed.
