SAFETY
CONSIDERATIONS
Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should
install, repair, or service air-conditioning
equipment.
Untrained personnel can perform basic maintenance functions of cleaning coils and filters and replacing filters. All
other operations should be performed by trained service personnel. When working on air-conditioning equipment, observe
precautions in the literature, tags and labels attached to the unit,
and other safety precautions that may apply.
Follow all safety codes, including ANSI (American National Standards Institute) Z223.1. Wear safety glasses and work
gloves. Use quenching cloth for unbrazing operations. Have
fire extinguisher available for all brazing operations.
Before performing service or maintenance operations on
unit, turn off main power switch to unit. Electrical shock
could cause personal iniury.

Curb Gasketing
Disconnect gas piping from units when leak testing at pressures greater than 0.5 psig. Pressures greater than 0.5 psig
will cause gas valve damage resulting in a hazardous
condition. If gas valve is subjected to pressure greater than
0.5 psig, it must be replaced. When pressure testing fieldsupplied gas piping at pressures of 0.5 psig or less, the unit
connected to such piping must be isolated by manually
closing the gas valve.
INSTALLATION
SIZE 030-050 UNITS -- After ductwork has been connected
to the roof curb, attach adhesive-backed
gasketmg on all end
rails, cross rails, and duct rails. Be sure all joints and corners of
gasket are square and flush to prevent possible water leaks.
Follow all applicable building codes.
SIZE 055-105 UNITS -- After ductwork has been connected
to the roof curb, apply gasket material (1/:-in. thick x ll/:-in.
wide neoprene) where indicated.
Single-Thickness
Gasketing (See Fig 6-8 for Item Numbersl -- Apply gasketing in the following places:
1. Along both side rails (1) -- 2 places,

1. Consult local building codes and the NEC (National
Electrical Code) (ANSI!NFPA [American National Standards Institute/National Fire Protection Association] 70)
for special installation requirements.
2. Determine unit location (from project plans) or select unit
location.
3.
Check for possible overhead obstructions
terfere with unit lifting or rigging.
which may in-
Do not lift unit with forklift truck. Move unit with overhead rigging only.
Unit Placement
E Inspect unit for transportation
age. File claim with transportation agency.
Check unit dimensional drawings for unit arrangement and
lnmimum performance and service clearances.
Do not install unit in an indoor location. Do not locate air inlets near exhaust vents or other sources of contaminated air.
On units equipped with power exhaust option, high velocity
air is exhausted out the hood. Unit should be positioned with at
least 10 ft clearance between the exhaust hood and any obstruction. Although unit is weatherproof,
guard against water from
higher level runoff and overhangs.
Physical data is
Roof Mount
_ Check building codes for weight distribution requirements. Unit weight is shown in Tables 1A-1C and
2. Unit may be mounted on class A, B, or C roofing material.
ROOF CURB -- Assemble and install roof curb as described
in instructions shipped with the accessory. Accessory roof curb
and information required to field fabricate a roof curb is shown
in Fig. 1-5. Install insulation, cant strips, roofing and counter
flashing as required. For unit condensate dram to function
properly, curb must be level or within tolerances shown m
Fig. 1-5.
STEEL BEAMS -- If roof curb is not used, support unit with
steel beams along its entire length and then support steel as required. As a minimum, unit must be supported across its width
at each lifting lug location.
Slab Mount
Double-Thickness
Gasketing (See Fig 6 and 8 and Detail
A-A! -- Locate a line 93/4-in. from the supply air end of the
accessory curb. Apply a double-thickness
of gasket material
along with line per detail A-A.
NOTE: Do not apply gasket material along the outside edge of
the curb (area "X"). This pan area of the curb extends out
beneath the end of the unit's air handler section; applying gasket here develops a potential water trap area on top of the curb.

Provide clearance around and above unit for airflow, safety,
and service access. Do not restrict top (area above condenser
fans) in any way. Allow at least 6 ft on all sides for rated performance, code compliance, and service.
Level by using unit frame as a reference.
shown in Tables 1A-6.
1 place
_ Provide a level concrete slab that extends
beyond unit cabinet at least 6 inches. Make a slab 8 in. thick
with 4 in. above grade. Use gravel apron m front of condenser
coil air inlet to prevent grass and foliage from obstructing
airflow. Ensure that slab is of sufficient height to allow for condensate trap of 4 in. on sizes 030-070 or 7 m. on sizes 075-105.
For vertical supply and return units, tools or parts could
drop into ductwork and cause an injury. Install a 90-degree
turn in the supply and return ductwork between the unit
and the conditioned space. If a 90-degree elbow cannot be
installed, then a grille of sufficient strength and density
should be installed to prevent objects from falling into the
conditioned space. Failure to follow these instructions
could result in personal injury or property damage due to
falling objects.
The 48ZG, ZN, ZT, ZW, Z6,Z8 units are designed for vertical
supply/return only. Field-fabricated ductwork must be attached
to the roof curb, on to the support steel, prior to the final rigging
and installation of the unit. Supply and return duct dhnensions
are shown in Fig. 1-3.
To attach ductwork to roof curb, insert duct approximately 10
to 11 m. up into roof curb. Connect ductwork to 14-gage roof
curb material with sheet metal screws driven from inside the duct.
Secure all ducts to the building structure, using flexible duct
connectors between roof curbs and ducts as required. Ducts
passing through an unconditioned space must be insulated and
covered with a vapor barrier. Outlet grilles must not lie directly
below unit discharge. The return duct must have a 90-degree
elbow before opening into the building space if the unit is
equipped with power exhaust.
Design supply duct strong enough to handle expected static
pressures.
Rigging
_ Do not drop unit; keep upright. Use spreader
bars over unit to prevent sling or cable damage. Sheets of plywood placed along the condenser coils will provide additional
protection. All lifting lugs MUST be used when lifting unit.
Level by using unit frame as a reference. See Fig. 9-13 for mformation. Unit and accessory weights are shown in Tables 1A1C and 2. Weight distribution and center of gravity can be
found in Fig. 14.

Condensate
Drain Connections
-- There are a total of five dram connections required on each unit: one primary
dram (on right-hand side of the unit) and four secondary drains
(two on each side of unit).
Fill the U-traps at the secondary drain locations prior to unit
start-up. Also check the U-traps before each cooling season to
ensure the traps are filled and functioning properly.
SECONDARY
DRAINS (Units Installed on Steel Beam or
Slab) -- There are two secondary dram connections required
on each side of the unit. See Fig. 26. There are secondary
drams on each side of the unit in the filter section and one on
each side of the unit m the supply fan section. There are labels
marking each location on the unit base rail. See Fig. 15-23. Prior to final positioning of the unit, apply a bead of RTV or similar sealant around each secondary drain hole in the bottom of
the unit base rail. Then position the unit into final location.
PRIMARY DRAIN -- The primary drain is a 2-in. NPT pipe
connection located on the right-hand side of the unit looking at
the unit from the return air end. See Fig. 15-24.
With field-supplied fittings and pipe sections, plumb the primary condensate drain to the 2-in. FPT connector on the base
rail. Use a trap height of at least 4-in. for size 030-070 units
and 7-m. for size 075-105 units. See Fig. 24 and 25. Install with
a height dimension of at least 2-in. from the top of the exit pipe
from the trap section to the bottom of the connector. Apply a
bead of RTV or sfinilar sealant around the pipe joint at the connector in the base rail.
Locate the four 11/4-m. drain coupling assemblies
and
mounting screws (shipped in a bag taped to the basepan in the
supply fan section, located behind the access panel marked
FAN SECTION). The drain couplings are a 10-gage plate with
a 11/4 m. half coupling welded to the plate.
SECONDARY
DRAINS
(Units
Installed
on
Curb) -- There are two secondary dram connections on each
side of the unit. See Fig. 26. There are secondary drains on
each side of the unit in the filter section and one on each side of
the unit in the supply fan section. There are labels marking
each location on the unit base rail. See Fig. 15-23.
After final positioning
procedure:
of the unit, perform
the following
1. At each of the four secondary drain locations (marked
with labels on the unit base rail), position the drain coupling assembly in the side of the base rail. Mark the
screw holes and the drain hole locations on the base rail.
Locate the four P/4-m. drain coupling assemblies
and
mounting screws (shipped in a bag taped to the basepan in the
supply fan section, located behind the access panel marked
FAN SECTION). The drain couplings are a 10-gage plate with
a 11/4in. half coupling welded to the plate.
At each secondary drain hole location, there is a 13/s-in.
hole pre-drilled in the bottom of the base rail, surrounded by
four 0.20-in. engagement holes. Install a drain coupling assembly using screws provided at each secondary drain hole location. See Fig. 27. Do not attach any dram coupling assemblies
in the condenser section base rail.
Using field-supplied fittings and pipe sections, assemble Utraps at each secondary drain fitting. See Fig. 28. Provide a
mmilnum size of ½-in. pipe for secondary drams. Use a trap at
least 4-m. deep for size 030-070 units and 7-in. deep for size
075-105 units. Apply a bead of RTV or similar sealant around
the dram assemblies.
2.
Drill holes for drain outlet (use 13/s-in. hole saw) and for
the mounting screws (use 3/j6-in. drill bit).
