R--410A QUICK REFERENCE GUIDE
•R--410A refrigerant operates at 50% -- 70% 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.
•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 when charging into suction line with compressor operating.
•Manifold sets should be 750 psig high--side and 200 psig low--side with 520 psig low--side retard.
•Use hoses with 750 psig service pressure rating.
•Leak detectors should be designed to detect HFC refrigerant.
•R--410A, as with other HFC refrigerants, 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 with 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 and replace all filter--driers. Evacuate
to 500 microns before recharging.
•Do not vent R--410A into the atmosphere.
•Do not use capillary tube indoor coils.
•Observe all WARNINGS,CAUTIONS, NOTES, and bold text.

MULTIPLYING FACTORS
(Refer to pages 7--13)
† Total capacities are net (I.D. blower heat subtracted) system capacities based on 25’ line set.
If additional tubing length and/or indoor unit is located above outdoor unit, a slight variation in capacity may occur.
†† At TVA rating indoor condition (75 °Fdb, 63 °Fwb), all other indoor air temperatures are at 80 °Fdb
If additional tubing length and/or indoor unit is located above outdoor unit, a slight variation in capacity may occur.
* System amps are total of indoor and outdoor amps. ‡ Chart data is for 80°F indoor dry bulb. For indoor db temperatures other than 80°F, measure Indoor db and Indoor CFM, and plug these into the
formula below. Measure outdoor db and indoor wet bulb, apply these to the chart above, find MBh and S/T, and plug these into the formula below. (Note: if indoor db is the only thing changing, total capacity, MBh, stays the same.)
Sensible Capacity at Indoor db LOWER than 80 °F=(MBhxS/T) -- ( 80 -- Indoor db ) x 835 x Indoor CFM

Sensible Capacity at Indoor db HIGHER than 80 °F=(MBhxS/T)+
