AIR CONDITIONER INSTALLATION
General Information
The P5RD packaged air conditioner is designed only
for outdoor ground level installations and can be readily
connected to the high static duct system of a home.
This unit has been tested for capacity and effi ciency in
accordance with A.R.I. Standards and will provide many
years of safe and dependable comfort, providing it is
properly installed and maintained. Abuse, improper use,
and/or improper maintenance can shorten the life of the
appliance and create unsafe hazards.
To achieve optimum performance and minimize equipment
failure, it is recommended that periodic maintenance be
performed on this unit. The ability to properly perform
maintenance on this equipment requires certain
mechanical skills and tools.
Before You Install this Unit
The cooling load of the area to be conditioned must be
calculated and a system of the proper capacity selected.
It is recommended that the area to be conditioned be
completely insulated and vapor sealed.
Check the electrical supply and verify the power supply
is adequate for unit operation. The system must be wired
and provided with circuit protection in accordance with
local building codes. If there is any question concerning
the power supply, contact the local power company.
Survey the job site to determine the best location for
mounting the unit. If possible, select a site that is as
close as possible to the proposed return grille location.
The unit is securely packed at the time of shipment and
upon arrival should be carefully inspected for damage
prior to installing the equipment at the job site. Verify
coil fi ns are straight. If necessary, comb fi ns to remove
fl attened or bent fi ns. Claims for damage (apparent or
concealed) should be fi led immediately with the carrier.
Please consult your dealer for maintenance information
and availability of maintenance contracts. READ ALL
INSTRUCTIONS BEFORE INSTALLING THE UNIT.
Locating the Air Conditioner
• Select a solid, level position, preferably on a concrete
slab, slightly above the grade level, and parallel to the
home. DO NOT PLACE UNIT UNDER THE HOME.
• The hot condenser air must be discharged up and away
from the home, and if possible, in a direction with the
prevailing wind.
• If practical, place the air conditioner and its ducts in
an area where they will be shaded from the afternoon
sun, when the heat load is greatest.
• The length of the supply and return ducts should be
kept to a minimum with no sharp radius bends.
• Overhead obstructions, poorly ventilated areas, and
areas subject to accumulation of debris should be
avoided. Do not place the unit in a confi ned space or
recessed area that will allow discharge air from the unit
to re-circulate into the condenser air inlet, through the
coil.
• Consideration should be given to availability of electric
power, service access, noise, and shade.
Unpacking the Unit
It is recommended that the unit be unpacked at the
installation site to minimize damage due to handling.
CAUTION:
Do not tip the unit on its side. Oil may enter
the compressor cylinders and cause starting
trouble. If unit has been set on its side, restore
to upright position and do not run for several
hours. Then run unit for a few seconds. Do this
three or four times with fi ve minutes between
runs.
1. Remove the bands from around the unit.
2. Unfold the top and bottom cap fl anges.
3. Carefully remove the top cap and tube.
Minimum Clearance Requirements
Suffi cient clearance for unobstructed airfl ow through the
outdoor coil must be maintained in order to provide room
for proper servicing and achieve rated performance. See
Figure 2 for minimum clearances to obstructions.
