1 Certified in accordance with the Air-Source Unitary Air-conditioner Equipment certifi-
cation program, which is based on AHRI standard 210/240. In order to achieve AHRI
standard rating, the indoor fan time delay on the comfort control must be enabled.
2 Rated in accordance with AHRI standard 270.
3 Calculated in accordance with Natl. Elec. Codes. Use only HACR circuit breakers or
fuses.

6 Max. linear length 80 ft.; Max. lift - Suction 25 ft.; Max lift - Liquid 25 ft.
For greater length consult refrigerant piping software Pub. No. 32-3312-0*
(* denotes latest revision).
7 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.
8 NO means no start components. YES means quick start kit components. PTC means
positive temperature coefficient starter.
CAUTION
!
CONTAINS REFRIGERANT!
SYSTEM CONTAINS OIL AND REFRIGERANT UNDER
HIGH PRESSURE. RECOVER REFRIGERANT TO RELIEVE
PRESSURE BEFORE OPENING SYSTEM.
Failure to follow proper procedures can result in personal
illness or injury or severe equipment damage.
CAUTION
!
