PACKAGED GAS HEATING/
ELECTRIC COOLING UNITS
fnmi IP
Models 585A/YAC, 585A/YACR, and 586A/YACX^are siiitle-
packaged gas heating/electric cooling horizontal-discharge
units.
The 585A/YAC is the standard natural-gas model with a
standing pilot and glow-coil ignition. The 585A/YACR is the
natural or propane model supplied with the RELITE-t 3 T)e
pilot that saves gas by operating only when the wall ther¬
mostat calls for heating. The 586A/YACX is the deluxe
model with RELITE-type pilot and many value added
features for reliability and performance.
These units are designed for outdoor installation either on a
rooftop or at ground level on a slab. The cooling section is
factory-charged and sealed, minimizing installation time.
Installation is easy—connect gas supply, air ducts, conden¬
sate drain, high- and low-voltage wiring, and install the air
filter.
A full line of rooftop system accessories are available for
field installation. These accessories include plenums with
factory-supplied high-capacity filter and outside air intake
hood, unitized curbs, economizers (both plenum-installed
and horizontal), barometric relief dampers, concentric
diffuser box assemblies, flexible duct packages, and high-ca¬
pacity filter racks with filters. When installing these ac¬
cessories, see installation instruction packaged with them.
Important—Read Before Installing
1. Check all local or other applicable codes for information
concerning proximity to property lines, height above
roof, obstructions, etc.
2. Make certain power supply available (volts, hertz, and
phase) corresponds to that specified on unit rating plate.
3. Check electrical supply provided by utility to be sure
that service capacity is sufiicient to handle load imposed
by this unit.
4. Locate the unit where the vent cap is a minimum of 4
feet from openable windows or doors,
5. The installation must conform with local building codes
or, in the absence of local codes, with the National Fuel
Gas Code ANSI Z223.1.
GENERAL
The condensing section has been designed and tested in ac¬
cordance with ARI 210. The appliance design is certified by
American Gas Association for use with natural or propane
gases with appropriate controls and orifices.

I. MOVING AND SETTING UNIT IN PLACE
Extreme caution should be used to prevent damage when
moving the unit. The unit should remain in an upright posi¬
tion during all rigging and moving operations. Ib facilitate
lifting and moving, place the unit in an adequate rope or
cable sling.
CAUTION: Be sure to protect the top and sides of the unit
when rigging the unit to be lifted. See Figure 4.
A. Rooftop Installation
Place the unit on a level base that is at least 6 inches above
the roof to prevent flooding. Consult local codes for installa¬
tion requirements. Be sure the roof will support the addi¬
tional weight.
NOTE: See the installation instructions packaged with the
accessory plenum and imitized curb when these system ac¬
cessories are being installed.
B. Ground Level Installation
Place the unit on a level concrete slab with a minimum of 4
inches thickness.
CAUTION: Unit must be moimted level for proper conden¬
sate drainage.
C. Clearances
The minimum clearance is 6 inches from the duct side, 24 in¬
ches from the condenser coil side, and 30 inches from the re¬
maining two sides of the imit to allow for adequate service
space. Minimum clearance from the top is 24 inches.
