construction market require the outdoor unit, indoor unit, refrig-
erant tubing sets, metering device, and filter &ier listed in presale
literature. There can be no deviation. Consult the Application
Guideline and Service Manual Air Conditioners and Heat Pumps
Using Puron:R; Refi'igerant 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
is damaged or incomplete. Locate unit rating plate on unit corner
panel. It contains information needed to properly install unit.

It"conditions o1"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. 3
to detemline 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
and minimize transmission of vibration to building. Consult local
codes governing rooftop applications.

Do not allow POE lubricant to come into contact with roofing
material. 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 Air Conditioners and Heat Pumps Using Puron'K Refrig-
erant 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
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 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.
Step 5--Elevate Unit
F':![,_rii[,]_l
Accumulation of water and ice in base pan may cause
equipment damage.
Elevate unit per local climate and code requirements to provide
clearance above estimated snowfall level and ensure adequate
drainage of the unit. Fig. 4 shows unit with accesso W support feet
