Introduction
This manual contains the installation and operating instructions for your packaged rooftop system. There are a few precautions that should be taken to derive maximum satisfaction
from it. Improper installation can result in unsatisfactory operation or dangerous conditions.
Read this manual and any instructions packaged with separate
equipment required to make up the system prior to installation.
Give this manual to the owner and explain its provisions. The
owner should retain this manual for future reference.
Checking Product Received
Upon receiving the unit, inspect it for any damage from shipment. Claims for damage, either shipping or concealed, should
be filed immediately with the shipping company. Check the
unit model number, heating size, electrical characteristics, and
accessories to determine if they are correct.
Equipment Protection From The
Environment
The metal parts of this unit may be subject to rust or deterioration in adverse environmental conditions. This oxidation could
shorten the equipment’s useful life. Salt spray, fog or mist in
seacoast areas, sulphur or chlorine from lawn watering systems, and various chemical contaminants from industries such
as paper mills and petroleum refineries are especially corrosive.
If the unit is to be installed in an area where contaminants
are likely to be a problem, special attention should be
given to the equipment location and exposure.
1 Avoid having lawn sprinkler heads spray directly on the
unit cabinet.
2 In coastal areas, locate the unit on the side of the building
away from the waterfront.
3 Shielding provided by a fence or shrubs may give some
protection.
Regular maintenance will reduce the buildup of contaminants and help to protect the unit’s finish.
1 Frequent washing of the cabinet, fan blade and coil with
fresh water will remove most of the salt or other contaminants that build up on the unit.
2 Regular cleaning and waxing of the cabinet with a good
automobile polish will provide some protection.
3 A good liquid cleaner may be used several times a year to
remove matter that will not wash off with water.
Several different types of protective coatings are offered in
some areas. These coatings may provide some benefit, but the
effectiveness of such coating materials cannot be verified by
the equipment manufacturer.
The best protection is frequent cleaning, maintenance and
minimal exposure to contaminants.
Recognize this symbol as an indication of

Installation
General
1 PRE-INSTALLATION CHECK-POINTS
Before attempting any installation, the following points
should be carefully considered:
a Structural strength of supporting members.
(rooftop installation)
b Clearances and provision for servicing.
c Power supply and wiring.
d Air duct connections.
e Drain facilities and connections.
f Location for minimum noise.
2 LOCATION
These units are designed for outdoor installations. They
can be mounted on a slab or rooftop. They are not to be
installed within any part of a structure such as an attic,
crawl space, closet, or any other place where condenser
air flow is restricted or other than outdoor ambient conditions prevail. Since the application of the units is of the
outdoor type, it is important to consult your local code
authorities at the time the first installation is made.
Outside Slab Installation
(Typical outdoor slab installations are shown in Figures 7 and 8.)
1 Select a location where external water drainage cannot
collect around the unit.
2 Provide a level concrete slab extending 3" [76.2 mm]
beyond all four sides of the unit. The slab should be sufficient above grade to prevent ground water from entering
the unit. IMPORTANT: To prevent transmission of noise or
vibration, slab should not be connected to building structure.
3 The location of the unit should be such as to provide
proper access for inspection and servicing.
4 Locate unit where operating sounds will not disturb
owner or neighbors.
5 Locate unit so roof runoff water does not pour directly on
the unit. Provide gutter or other shielding at roof level.
Do not locate unit in an area where excessive snow drifting may occur or accumulate.
Clearances
The following minimum clearances must be observed for
proper unit performance and serviceability.
1 Provide 48" [1219.2 mm] minimum clearance at the front
of the unit. Provide 18" [457.2 mm] minimum clearance
at all other sides of the unit.
2 Provide 60" [1524 mm] minimum clearance between top
of unit and maximum 3 foot [.91 m] overhang.
3 Unit is design certified for application on combustible
flooring with 0" [0 mm] minimum clearance.

Rooftop Installation
1 Before locating the unit on the roof, make sure that the
strength of the roof and beams is adequate at that point to
support the weight involved. This is very important and
user’s responsibility.
2 For rigging and roofcurb details, see Figures 9 and 10.
Use field-furnished spreaders.
3 For roofcurb assembly, see Roofcurb Installation Instruc-
tions.
4 If the roofcurb is not used, provisions for disposing of
condensate water runoff must be provided.
5 The unit should be placed on a solid and level roofcurb or
platform of adequate strength. See Figure 11.
6 The location of the unit on the roof should be such as to
provide proper access for inspection and servicing.

Ductwork
Ductwork should be fabricated by the installing contractor in
accordance with local codes and NFPA90A. Industry manuals
may be used as a guide when sizing and designing the duct
system - contact Air Conditioning Contractors of America,
1513 16th St. N.W., Washington, D.C. 20036.
The unit should be placed as close to the space to be air conditioned as possible allowing clearance dimensions as indicated.
Ducts should be run as directly as possible to supply and
return outlets. Use of non-flammable waterproof flexible connectors on both supply and return connections at the unit to
reduce noise transmission is recommended.
It is preferable to install the unit on the roof of the structure if
the registers or diffusers are located on the wall or in the ceiling. A slab installation could be considered when the registers
are low on a wall or in the floor.
On ductwork exposed to outside air conditions of temperature
and humidity, use a minimum of 2" [50.8 mm] of insulation
and a vapor barrier. Distribution system in attic, furred space
or crawl space should be insulated with at least 2" [50.8 mm]
of insulation with vapor barrier. One-half to 1" [25.4 mm]
thickness of insulation is usually sufficient for ductwork inside
the air conditioned space.
Balancing dampers should be provided for each branch duct in
the supply system. Ductwork should be properly supported
from the structure.
When installing ductwork, consider the following items:
1 Noncombustible flexible connectors should be used
between ductwork and unit to reduce noise and vibration
transmission into the ductwork.
2 When auxiliary heaters are installed, use noncombustible
flexible connectors and clearance to combustible material
of 0" [0 mm] for the first 3 feet [.91 m] of discharge duct.
Clearance to unit top and side is 0" [0 mm].
Filters
This unit is provided with 6 - 2" x 18" x 18" [51mm x 457 mm
x 457 mm] disposable filters. When replacing filters, ensure
they are inserted fully to the back to prevent bypass.
Conversion Procedure
Downflow To Horizontal
1 Remove the screws and covers from the outside of the
supply and return sections.
2 Install the covers over the bottom supply and return open-
ings, painted side up inserting the leading flange under the
bracket provided. Place the back flange to the top of the
front bracket provided. See Figure 12.
3 Secure the return and supply cover to the front bracket
with one (1) screw.
Condensate Drain
The condensate drain connection of the evaporator is
1" [25.4 mm] nominal female pipe thread. IMPORTANT:
Install a condensate trap to ensure proper condensate drainage.
See Figure 13.

Indoor Air Flow Data
Belt-drive blower models have motor sheaves set for proper
CFM at a typical external static. See Tables C through G for
blower performance.
Crankcase Heat (Optional)
Crankcase heat is not required on scroll type compressors, but
may be desirable under certain conditions.
Pre-Start Check
1 Is unit properly located and slightly slanted toward indoor
condensate drain?
2 Is ductwork insulated, weatherproofed, with proper spac-
ing to combustible materials?
3 Is air free to travel to and from outdoor coil? (See Figure
5.)
4 Is the wiring correct, tight, and according to unit wiring
diagram?
5 Is unit grounded?
6 Are field supplied air filters in place and clean?
7 Do the outdoor fan and indoor blower turn freely without
rubbing, and are they tight on the motor shafts?
Startup
1 Turn thermostat to “OFF,” turn “on” power supply at
disconnect switch.
2 Turn temperature setting as high as it will go.
3 Turn fan switch to “ON.”
4 Indoor blower should run. Be sure it is running in the
right direction.
5 Turn fan switch to “AUTO.” Turn system switch to
“COOL” and turn temperature setting below room temperature. Unit should run in cooling mode.
6 Is outdoor fan operating correctly in the right direction?
7 Is compressor running correctly.
Record the following after the unit has run some time.

8 Turn thermostat system switch to “HEAT.” Unit com-
pressors should stop. Raise temperature setting to above
room temperature. Unit should run in heating mode and
auxiliary heaters, if installed, should come on.
9 Check the refrigerant charge using the instructions
located on unit charging chart. Replace service port
caps. Service port cores are for system access only and
will leak if not tightly capped.
10 Adjust discharge air grilles and balance system.
11 Check ducts for condensation and air leaks.
12 Check unit for tubing and sheet metal rattles.
13 Instruct the owner on operation and maintenance.
14 Leave “INSTALLATION” and ”USE AND CARE“
instructions with owner
Operation
Cooling Mode
With thermostat in the cool mode, fan auto and the room temperature higher than the thermostat setting:
1 Indoor blower contactor is energized through thermostat
contact (G).
2 Compressor contactors are energized through thermostat
contacts (Y1) & (Y2) and high pressure controls.
3 Economizer enthalpy control (if installed) controls opera-
tion of first-stage cooling and positions fresh air damper
to maintain mixed air temperature. Second-stage cooling
operates normally as required by second stage of thermostats.
4 The system will continue in cooling operation as long as
all safety controls are closed, until the thermostat is satisfied.
Heating Mode
With the thermostat in heat mode, fan on auto, and the room
temperature lower than the thermostat setting, the Indoor
blower contactor is energized through thermostat contact (G).
In the heating mode, the thermostat will energize one or more
supplementary heaters.
