Payne PA13NR036 - User Manual

Installation Instructions
SAFETY CONSIDERATIONS
Improper installation, acljustment, alteration, service, maintenance,
or use can cause explosion, fire, electrical shock, or other
conditions which may cause death, personal iniury, or property
damage. Consult a qualified installer, service agency, or your
distributor or branch for information or assistance. The qualified
installer or agency must use factory-authorized kits or accessories
when modifying this product. Refer to the individual instructions
packaged with the kits or accessories when installing.
Follow all safety codes. Wear safety glasses, protective clothing,
and work gloves. Use quenching cloth for brazing operations.
Have fire extinguisher available. Read these instructions
thoroughly and follow all warnings or cautions included in
literature and attached to the unit. Consult local building codes and
current editions of the National Electrical Code ( NEC ) NFPA 70.
In Canada, refer to current editions of the Canadian electrical code
CSA 22.1.
Recognize safety information. This is the safety-alert symbol/k
When you see this symbol on the unit and in instructions or
manuals, be alert to the potential for personal injury. Understand
these signal words; DANGER, WARNING, and CAUTION.
These words are used with the safety-alert symbol. DANGER
identifies the most serious hazards which will result in severe
personal injury or death. WARNING signifies hazards which could
result in personal injury or death. CAUTION is used to identify
unsafe practices which would result in minor personal injury or
product and property damage. NOTE is used to highlight
suggestions which will result in enhanced installation, reliability,
or operation.
ELECTRICALSHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
Before installing, modifying, or servicing system, main
electrical disconnect switch must be in the OFF position.
There may be more than 1 disconnect switch. Lock out and
tag switch with a suitable warning label.
INSPECT NEW UNIT
After un-crating unit, inspect thoroughly for hidden damage. If
damage is found, notify the transportation company immediately
and file a concealed damage claim.
LOCATION
Check local codes for regulations concerning zoning, noise,
platforms, and other issues.
Locate unit away from fresh air intakes, vents, or bedroom
windows. Noise may carry into the openings and disturb people
inside.
Locate unit in a well drained area, or support unit high enough so
that water runoff will not enter the unit.
Locate unit away from areas where heat, lint, or exhaust fumes will
be discharged onto unit (as from dryer vents).
Locate unit away from recessed or confined areas where
recirculation of discharge air may occur (refer to CLEARANCE
REQUIREMENT section of this document).
Roof-top installation is acceptable providing the roof will support
the unit and provisions are made for water drainage and
noise/vibration dampening.
NOTE: Roof mounted units exposed to wind may require wind
baffles. Consult the manufacturer for additional information.
CLEARANCE REQUIREMENTS
Nominal minimum clearances are 48 inches (1.2m) above unit for
discharge air and 18 inches (457 mm) on each side of the coil for
intake air. Clearance on any one side of the coil (normally between
unit and structure) may be reduced to 6 inches (152 mm). Nominal
minimum clearances are based on a solid parallel object such as a
wall or roof overhang.
The clearance may be reduced for a single object with small surface
area, such as the end of a wall, outside corner of a wall, fence
section, post, etc. As a general rule, the minimum clearance from
the unit should equal the width of the object. For example, a 6 inch
(152 mm) fence post should be a minimum of 6 inches (152 mm)
from the unit.
Do not install unit under roof overhangs unless gutters are present.
A minimum vertical clearance of 48 inches (1.2m) is required to
the overhang.
Inside corner locations on single story structures require
evaluation. Large overhanging soffit may cause air recirculation in
a corner area even though recommended minimum clearances are
maintained. As a guide, locate the unit far enough out so that half
of the discharge grille is out from under the soffit.
When placing two or more units side-by-side, provide a minimum
of 18 inches (457 mm) between units.
Provide minimum service clearance of 24 inches (610 mm) from
control box corner and side service panel. See Fig. 1.
