Clearance Requirements
When installing, allow sufficient space for airflow clearance,
wiring, refrigerant piping, and service. Allow 30--in. clearance to
service end of unit and 48 in. above unit. For proper airflow, a
6--in. clearance on 1 side of unit and 12 in. on all remaining sides
must be maintained. Maintain a distance of 24 in. between units.
Position so water, snow, or ice from roof or eaves cannot fall
directly on unit.
On rooftop applications, locate unit at least 6 in. above roof
surface.

Operating Ambient
The minimum outdoor operating ambient in cooling mode is
55
_
F without low ambient cooling enabled, and the maximum
outdoor operating ambient in cooling mode is 125
_
F. On Infinity
communicating systems only, for both 24ANA1 and 24ANA7
models, low ambient cooling is available to 0
_
F.

Install TXV
NOTE
: Applies to non--TXV indoor units only. If installing a
rated and approved indoor coil without a factory installed Puron
TXV, remove and replace the fixed orifice or R--22 TXV
expansion device with a hard shutoff Puron balance port TXV.
The thermostatic expansion valve is specifically designed to
operate with Puron. Do not use an R--22 TXV. An existing R--22
TXV must be replaced with a factory--approved TXV specifically
designed for Puron.
Refer to Product Data Sheet for the
appropriate TXV kit number.
