Fig. 3--Connecting Tubing InstNtat{on
When outdoor unit is connected to factory-approved indoor unit,
outdoor unit contains systen>ref?igerant charge tbr operation with
indoor unit of the same size when connected by 15 ft of
field=supplied or fhctory=accessow- robing For proper unit opera=
tion, check refrigerant charge using charging information located
on control-box cover and/or in the (hock Charge section of this
Instruction.
--> iMPORTANT: Maximum liquid-line size is 3/%in. O.D. for all
residential applications including tong line applications.
---> IMPORTANT: Always install a liquid=line filter drier on any
system using an existing field service lineset and/or existing indoor
coil. Also, always use liquid line tilter driers on burnout compres=
sot replacments. Refer to Product Data Digest for appropriate part
number. Obtain filter &ier fi'om your distributor or branch.
BNSTALLATION
Step 1--Check Equipment and Job Site
[ NPACK LNI7
Move to final location, Remove cartom taking care not to damage
uniL
INSPECT EQUIPMENT
File claim with shipping company prior to installation if shipment
is damaged oi" incomplete, Locate unit=rating plate on unit=service
panel It contains information needed to properly install unit
Check rating plate to be sure unit matches job specifications,
Step 2--_nstaH on a Solid, Level Mounting Pad
If conditions or local codes require the unit be attached to pad,
tie=down bolts should be used and fastened through knockouts
provided in unit base pan. Refer to unit=mounting pattern in Fig 4
to detem_ine base=pan size and knockout=hole location.
On rooftop applications, mount on level plati:orm or fi'ame 6 in
above roof sur_ce. Place unit above a load=bearing wall and
isolate unit and robing set tiom structure Arrange supporting
members to adequately support unit and minimize transmission of
vibration to building. Consult local codes governing rooftop
applications.
Roof mounted units exposed to winds above 5 mph may require
wind baffles to achieve adequate defrost. Consult Low=Ambient
Guideline for wind=baffle construction.
NOTE: Unit must be level to within ÷2 ° (+3/8 inift) per
compressor manufacturer specifications.

Step 3--Clearance Requirements
When installing, allow sufficient space %r 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.
Step 4--Operating Ambients
The minin_mn outdoor-operating ambient in cooling mode is 55°F,
and the maximum outdoor=operating arnbient in cooling mode is
125°F The maxinmm outdoor-operating ambient in heating mode
is 66°F,
Step 5--Elevate Unit
& 0 TM
Accumulation of water and ice in base pan may cause
equipment damage.
In areas where prolonged freezing temperatures are encountered,
elevate unit per local climate and code requirements to provide
clearance above estimated snowfitll level and ensure adequate
drainage of unit
Step 6--Check indoor And Outdoor AccuRater® Piston
(heck indoor-coil piston to see if it matches the required piston
shown on outdoor unit=rating plate, If it does not match_ replace
indoor-coil piston with piston shipped with outdoor unit. The
piston shipped with outdoor unit is correct for any approved
indoor-coil combination,
