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 the 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. Wear safety glasses and work gloves. Use quenching cloth for unbrazing operations. Have fire extinguishers 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 injury.
1.Improper installation, adjustment, alteration, service, or maintenance can cause property damage, personal injury, or loss of life. Refer to the User’s Information Manual provided with this unit for more details.
2.Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance.
What to do if you smell gas:
1.DO NOT try to light any appliance.
2.DO NOT touch any electrical switch, or use any phone in your building.
3.IMMEDIATELY call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.
4.If you cannot reach your gas supplier, call the fire department.
Disconnect gas piping from unit when pressure testing at pressure greater than 0.5 psig. Pressures greater than 0.5 psig will cause gas valve damage resulting in hazardous condition. If gas valve is subjected to pressure greater than 0.5 psig, it must be replaced before use. When pressure testing field-supplied gas piping at pressures of 0.5 psig or less, a unit connected to such piping must be isolated by closing the manual gas valve(s).
INSTALLATION
Step 1 — Provide Unit Support
1.All panels must be in place when rigging.
2.Unit is not designed for handling by fork truck.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

ROOF CURB — For vertical discharge units, assemble or install accessory roof curb in accordance with instructions shipped with this accessory. See Fig. 1-4. Install insulation, cant strips, roofing, and counter flashing as shown. Ductwork can be installed to roof curb before unit is set in place. Curb should be level. This is necessary to permit unit drain to function properly. Unit leveling tolerance is shown in Fig. 1-3. Refer to Accessory Roof Curb Installation Instructions for additional information as required. When accessory roof curb is used, unit may be installed on class A, B, or C roof covering material.
IMPORTANT: The gasketing of the unit to the roof curb is critical for a watertight seal. Install gasket with the roof curb as shown in Fig. 1-3. Improperly applied gasket can also result in air leaks and poor unit performance.
ALTERNATE UNIT SUPPORT — When the preferred curb or slab mount cannot be used, support unit with sleepers on perimeter, using unit curb support area. If sleepers cannot be used, support long sides of unit (refer to Fig. 5-16) with a minimum number of 4-in. x 4-in. pads spaced as follows: 48AJ,AK,AW,AY020-030 and 48EJ,EK,EW,EY024-034 units require 3 pads on each side; 48AJ,AK,AW,AY035-050 and 48EJ,EK,EW,EY038-048 units require 4 pads on each side; 48AJ,AK,AW,AY060 and 48EJ,EK,EW,EY054-068 units require 6 pads on each side. Unit may sag if supported by corners only.
Step 2 — Rig and Place Unit — Inspect unit for transportation damage. See Tables 1A and 1B for physical data. File any claim with transportation agency.
Do not drop unit; keep upright. Use spreader bars over unit to prevent sling or cable damage. Level by using unit frame as a reference; leveling tolerance is shown in Fig. 1-3. See Fig. 17 for additional information. Unit operating weight is shown in Table 2.
NOTE: On retrofit jobs, ductwork may be attached to old unit instead of roof curb. Be careful not to damage ductwork when removing old unit. Attach existing ductwork to roof curb instead of unit.
Four lifting lugs are provided on the unit base rails as shown in Fig. 5-16. Refer to rigging instructions on unit.
POSITIONING — Maintain clearance, per Fig. 5-16, around and above unit to provide minimum distance from combustible materials, proper airflow, and service access.
Do not install unit in an indoor location. Do not locate unit air inlets near exhaust vents or other sources of contaminated air. For proper unit operation, adequate combustion and ventilation air must be provided in accordance with Section 5.3 (Air for Combustion and Ventilation) of the National Fuel Gas Code, ANSI Z223.1 (American National Standards Institute).
Although unit is weatherproof, guard against water from higher level runoff and overhangs.
Locate mechanical draft system flue assembly at least 4 ft from any opening through which combustion products could enter the building, and at least 4 ft from any adjacent building.
When unit is located adjacent to public walkways, flue assembly must be at least 7 ft above grade.
ROOF MOUNT — Check building codes for weight distribution requirements. See Fig. 17. Unit operating weight is shown in Table 2.
Step 3 — Field Fabricate Ductwork — Secure all ducts to building structure. Use flexible duct connectors between unit and ducts as required. Insulate and weatherproof all external ductwork, joints, and roof openings with counter flashing and mastic in accordance with applicable codes.
NOTE: Due to width of the horizontal supply/return ductwork, provisions should be made for servicing of the outdoor air filters (i.e., catwalk over ductwork).
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.
To attach ductwork to roof curb, insert duct approximately 10 to 11 in. up into roof curb. Connect ductwork to 14-gage roof curb material with sheet metal screws driven from inside the duct.
For vertical supply and return units, tools or parts could drop into ductwork and cause an injury. Install a 90-degree elbow 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.
Step 4 — Make Unit Duct Connections
48AJ,AK,EJ,EK UNITS — Unit is shipped for through-the- bottom duct connections. Field-fabricated ductwork should be attached to the roof curb. Supply and return duct dimensions are shown in Fig. 5-7 and 11-13. Air distribution is shown in Fig. 18 and 19. Refer to installation instructions shipped with roof curb for more information.
48AW,AY,EW,EY UNITS — Remove shipping covers from supply and return air openings. Attach field-supplied ductwork to unit. Connect to the unit with a single duct for all supply openings and with a single duct for all return openings. Splitting of the airflow into branch ducts should not be done at the unit. Sufficient duct length should be used prior to branching to ensure the air temperatures are well mixed within the ductwork. See Fig. 8-10 and 14-16 for duct opening dimensions. Secure all ducts to building structure. Air distribution is shown in Fig. 8-10 and 14-16.
Install accessory barometric relief or power exhaust in the field-fabricated return ductwork. Refer to Step 11 — Position Power Exhaust/Barometric Relief Damper Hood section on page 52 for more information.

OPTIONAL STAGED GAS UNITS — The staging pattern is selected based on Heat Stage Type (HTSTGTYP). Max Capacity per changes default value is selected based on Capacity Maximum Stage (CAPMXSTG). See Table 4.
For complete information and service instructions for Staged Gas Control Units, see Control Operation and Troubleshooting literature.
Step 8 — Controls Options — The control options that the units can provide are based on the following parameters: CV (constant volume) or VAV (variable air volume) operation; stand-alone unit with field-supplied sensors installed (CV or VAV); as a system via Carrier Comfort System (TEMP or VVT® [Variable Volume and Temperature]); optional electronic expansion board installed (CV or VAV); linked to the Carrier Comfort Network; availability of a computer and software (ComfortWORKS® Building Supervisor, and Service Tool) or remote enhanced display accessory installed to access the base control board; and optional factory-installed staged gas control. See Table 5.
NOTE: Access to the base control board allows unit occupancy schedules, unit timeclock, and various set points to be changed from their factory-defined default settings.

STAGED GAS UNIT APPLICATIONS — The rooftop units may be ordered with an optional factory-installed staged gas control system that monitors heating operation of the rooftop unit.
IMPORTANT: An accessory field-supplied Navigator display module is required for all staged gas control units.
Install Supply-Air Thermistors (Staged Gas Units Only) — Supply-air thermistors are a field-installed factory-provided component. Three supply-air thermistors are shipped with staged gas units and are inside the heating section. Thermistor wires must be connected to SGC (staged gas controller) in the heating section. See Table 6 and Fig 24. The supply-air thermistors should be located in the supply duct with the following criteria:
•downstream of the heat exchanger cells
•equally spaced as far as possible from the heat exchanger cells
•a duct location where none of the supply air thermistors are within sight of the heat exchanger cells
•a duct location with good mixed supply air portion of the unit.
THERMISTORS — All units are equipped with a supply air thermistor (SAT) located in the supply fan discharge and an outdoor air thermistor (OAT) located in the outdoor air hood. Variable air volume (VAV) units are supplied with a return air thermistor (RAT) located on the return air damper support.
CONSTANT VOLUME APPLICATIONS — The units, as shipped, are operable as stand-alone units, using either a standard (mechanical or electronic) 2-stage heat, 2-stage cool thermostat, or with an electronic room sensor and a timeclock to establish unit start and stop times.
With a standard thermostat (programmable is optional), heating and cooling operation is set by space temperature.
With a space sensor and timeclock, the machine will operate at default values unless they are changed using appropriate input devices. The space sensor senses space temperature and may be equipped with a timed override feature, which allows unit operation during unoccupied periods.
The space sensors may be used in multiples of 4 or 9 to achieve space temperature averaging. The use of a space sensor also allows the unit to be turned on and off from a remote signal.
