construction market require using the outdoor unit, indoor unit,
refrigerant robing sets, metering device, and filter &ier listed in
presale literature. There can be no deviation. Consult the Appli-
cation Guideline and Service Manual for Residential Split-System
Air Conditioners and Heat Pumps using Puron:R; Refrigerant to
obtain required unit changes for specific applications and for R-22
retrofit.
Step 1--Check Equipment and Job Site
UNPACK UNIT
Move to final location. Remove carton taking care not to damage
unit.
INSPECT EQUIPMENT
File claim with shipping company prior to installation if shipment

down bolts should be used and fastened through knockouts
provided in unit base pan. Refer to unit mounting patteru in Fig. 3
to determine base pan size and knockout hole location.
On rooftop applications, mount on level platform or frame. Place
unit above a load-bearing wall and isolate unit and tubing set fi'om
structure. Arrange supporting members to adequately support unit

materiah POE may deteriorate certain types of synthetic
roofing.
Roof mounted units exposed to winds above 5 mph may require
wind baffles. Consult the Application Guideline and Service
Manual for Residential Split-System Air Conditioners and Heat
Pumps using Puron'K Refrigerant for wind baffle construction.
NOTE: Unit must be level to within ± 2 ° (± 3/8 in.ift) per
compressor manufacturer specifications.
Step a--Clearance Requirements
When installing, allow sufficient space for airflow clearance,
wiring, refrigerant piping, and service. Allow 30-in. clearance to
smwice 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 l'rom roof or eaves cannot fall
directly on unit.
On rooftop applications, locate unit at least 6 in. above roof
surface.
Step 4--Operating Ambient
The mininmm outdoor operating ambient in cooling mode without
additional accessories is 55°F, and the maximum outdoor operat-
ing ambient in cooling mode is 125°F. The maxinmm outdoor
operating ambient in heating mode is 66°F.
