GENERAL
This installation instruction contains base unit installation, start-up, and service instructions only. For complete information on PIC (Product Integrated Controls) controls and troubleshooting, refer to separate Controls and Troubleshooting literature also enclosed in this literature packet.
IMPORTANT:
1.Tune all loops immediately after starting units. Refer to Control Loop Checkout section on page 40 for more information on tuning loops.
2.The Data Reset function should be performed any time one or more of the unit factory con®guration values are changed.
3.The HSIO (human sensor input/output) keypad and display module is required for initial start-up of unit. All units are shipped in STANDBY mode. The HSIO must be used to change the unit to RUN mode. The HSIO is not required for normal operation, however, at any time the unit needs to be transferred back into STANDYBY mode, such as when servicing a unit, it must be done with the HSIO.
SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can be hazardous due to system pressure and electrical components. Only trained and quali®ed service personnel should install, repair, or service air-conditioning equipment.
Untrained personnel can perform basic maintenance functions of cleaning coils and ®lters and replacing ®lters. 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 ®re 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 injury.
Do not store or use gasoline or other ¯ammable vapors and liquids in the vicinity of this or any other appliance.
Improper installation, adjustment, alteration, service, or maintenance can cause injury or property damage. Refer to this manual. For assistance or additional information, consult a quali®ed installer or service agency.
This unit uses a microprocessor-based electronic control system. Do not use jumpers or other tools to short out components, or to bypass or otherwise depart from recommended procedures. Any short-to-ground of the control board or accompanying wiring may destroy the electronic modules or electrical components.
Disconnect gas piping from 48 Series 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 ®eld-supplied 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
Jobsite Survey Ð Complete the following checks before installation.
1.Consult local building codes and the NEC (National Electrical Code) (ANSI/NFPA [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 which may interfere with unit lifting or rigging.
Do not lift unit with forklift truck. Move unit with overhead rigging only.
Unit Placement Ð Inspect unit for transportation damage. File claim with transportation agency.
Provide clearance around and above unit for air¯ow, 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.
Check unit dimensional drawings for unit arrangement and minimum 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.
Level by using unit frame as a reference. Physical data is shown in Tables 1-4.
Roof Mount Ð Check building codes for weight distribution requirements. Unit weight is shown in Table 1. Unit may be mounted on class A, B, or C roo®ng material.
ROOF CURB Ð Assemble and install as described in instructions shipped with the accessory. Accessory roof curb and information required to ®eld fabricate a roof curb is shown in Fig. 1 and 2. Install insulation, cant strips, roo®ng, and counter ¯ashing as required. For unit condensate drain to function properly, curb must be level or within tolerances shown in Fig. 1 and 2.
STEEL BEAMS Ð 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 Ð 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 in front of condenser coil air inlet to prevent grass and foliage from obstructing air¯ow. Ensure that slab is of sufficient height to allow for 7-in. condensate trap.
Field-Fabricated Ductwork Ð Units are designed for vertical supply/return only. Field-fabricated ductwork should be attached to the roof curb. Supply and return duct dimensions are shown in Fig. 1-6.
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 of the duct.
Secure all ducts to the building structure, using ¯exible duct connectors between roof curb 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 unit is equipped with power exhaust.
Design supply duct strong enough to handle expected static pressures.
For vertical supply and return units, tools or parts could drop into ductwork and cause an injury. Install 90 degree turns in the supply and return ductwork between the unit and the conditioned space. If a 90 degree elbow cannot be installed, then grilles of sufficient strength and density should be installed to prevent objects from falling into the conditioned space.
Rigging Ð Do not drop unit; keep upright. Use spreader bars over unit to prevent sling or cable damage. Leave condenser coil shipping protection in place while rigging to prevent coil damage. All lifting lugs MUST be used when lifting unit.
Level by using unit frame as a reference. See Fig. 7 for information. Unit and accessory weights are shown in Tables 1-4. Weight distribution and center of gravity can be found in Fig. 8.
Condensate Drains Ð The condensate drain connection is a 1 1¤2-in. NPT pipe connection located on the right hand side of the unit. See Fig. 9.
NOTE: Use a trap of at least 7-in. deep.
Condenser Coil Shipping Covers Ð Remove and discard.
Install Outdoor Hoods
1.Outdoor-air hoods are shipped bolted to the unit in a shipping position. To open hoods, remove the 3 holddown bars holding the air hood in shipping position. See Fig. 10.
2.Lift up the highest hood top and swing out hood sides to form the outside frame of the air hood. Fasten hood top to hood sides at middle and top holes only, using two screws on each side. See Fig. 11.
3.Remove the bottom hood block-off plate and set aside.
4.Swing up second hood (from the top of unit) into place and fasten to hood sides with screws provided using upper hole only.
5.Swing up third hood (from the top of unit) into place and fasten to hood sides with screws provided using upper hole only.
6.Swing up fourth hood (bottom hood) into place. Before fastening hood to hood sides, swing down bottom ®lter rack. Fasten hood to hood sides with screws provided using upper hole only.
7.Attach block off plate removed from Step 3.
8.Clip wire tie holding ®lter track. Swing ®lter track into position and fasten to hood sides using screws provided. Repeat until all 4 ®lter racks have been installed.
9.Apply a bead of RTV or similar sealant to corner of each hood at pivot point to prevent water leaks.

POWER SUPPLY Ð Electrical characteristics of available power supply must agree with unit nameplate rating. Supply voltage must be within the limits shown in Table 5.
Field Wire Routing Ð Field wiring is brought into the unit through the bottom of the control box.
A 35¤8-in. hole for ®eld power wiring and a 7¤8-in. hole for 24-v control wiring are provided in the bottom of the control box. Field-supplied couplings must be used when routing wiring into the control box.
Field Electrical Connections
IMPORTANT: The 48/50MP units generate, use, and can radiate radio frequency energy. If units are not installed and used in accordance with these instructions, they may cause radio interference. They have been tested and found to comply with limits of a Class A computing device as de®ned by FCC (Federal Communications Commission) regulations, Subpart J of Part 15, which are designed to provide reasonable protection against such interference when operated in a commercial environment.
POWER WIRING Ð Units are factory wired for 460-v as shown on the unit nameplate. The main terminal block is suitable for use with aluminum or copper wires. Maximum wire size is 500 MCM.
Branch circuit for power supply to unit must be protected against ground fault or short circuit. Provide an overcurrent protection device in the branch circuit. The MOCP (Maximum Overcurrent Protection) value for this device is shown on unit informative data plate.
When installing units, provide and install a unit safety disconnect per NEC of adequate size. Refer to Electrical Data tables for disconnect sizing. Disconnect may incorporate branch circuit fusing (if local or national codes permit) but combination disconnect fuse is not required. Disconnect must be able to be locked OFF.

All ®eld wiring must comply with NEC and all local codes. Size wire based on MCA (Minimum Circuit Amps) value shown on the unit informative plate. See Fig. 12 for power wiring connections to the unit power terminal block and equipment ground.
Operating voltage to the compressor must be within the voltage range indicated on the unit nameplate. Voltages between phases must be balanced within 2%, and the current must be balanced within 10%. See Table 5 for unit electrical data.
Use the following formula to determine the percent voltage imbalance.
% Voltage Imbalance
max voltage deviation from average voltage
= 100 x
average voltage
EXAMPLE: Supply voltage is 460-3-60.
AB = 452 v BC = 464 v AC = 455 v
452 + 464 + 455
Average Voltage =
3
1371
=
3 = 457
Determine maximum deviation from average voltage: (AB) 457 − 452 = 5 v
(BC) 464 − 457 = 7 v (AC) 457 − 455 = 2 v
Maximum deviation is 7 v.
Determine percent voltage imbalance:
7
% Voltage Imbalance = 100 x
457
= 1.53%
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact local utility immediately.
Unit failure as a result of operation on improper line voltage or excessive phase imbalance constitutes abuse and may cause damage to electrical components.

SENSORS Ð Sensors should be wired using single twisted pairs of 20 AWG (American Wire Gage) conductor cable rated for the application, except for the T56 accessory sensor which requires 3-conductor cable.
NOTE: Humidity and CO2 sensors must be powered from isolated 24-v power supplies.
HUMIDITY CONTROL AND HOT WATER AND STEAM VALVES Ð These devices require 20 AWG twisted pair conductor cables rated for the application for the 4 to 20 mA signal.
SPACE TEMPERATURE SENSOR (T55) Ð The space temperature sensor (P/N CEC0121448-01) is shipped standard with every unit, and is located in the main control box. Space temperature sensor wires are to be connected to terminals in the unit main control box. The space temperature sensor includes a terminal block (TB1), a jumper between pins E2 and E3, and an RJ11 female connector. The RJ11 connector is used to tap into the Carrier Comfort Network (CCN) at the sensor. See RJ11 Plug Wiring section on page 24 to connect the RJ11 connector to the CCN. A 3-lead cable must run from the RJ11 connector to the unit for communication through the sensor.
Jumper MUST be in place between pins E2 and E3 or inaccurate readings could result.
To connect the space temperature sensor (Fig. 13):
1.Connect 1 wire of the twisted pair to terminal T1 (T55) and connect the other wire to terminal T2 on terminal block 1 (TB1) located on the cover of the space temperature sensor using a 20 AWG twisted pair conductor cable rated for the application.
2.Connect the other ends of the wires to terminals 1 and 2 on TB3 located in the unit main control box.
NOTE: This sensor should be installed for all applications. For VAV (variable air volume) applications, it is used to control heating and cooling during unoccupied periods. For DAV (digital air volume) applications, it is used to maintain control of the space during linkage failures with the TSM (terminal system manager).
NOTE: Either the T55 or T56 sensor must be connected for CV (constant volume) applications to function properly.
SPACE TEMPERATURE SENSOR (T56) (CV Applications Only) Ð The space temperature sensor (P/N CEC0121503-01) wires are to be connected to terminals in the unit main control box. The space temperature sensor includes a terminal block (TB1), a jumper between
pins E2 and E3, and an RJ11 female connector. The RJ11 connector is used to tap into the CCN at the sensor. See RJ11 Plug Wiring section on page 24 to connect the RJ11 connector to the CCN.
Jumper MUST be in place between pins E2 and E3 or inaccurate readings could result.
To connect the space temperature sensor (Fig. 13):
1.Connect one wire of the 3-conductor cable to terminal TH, one wire to terminal COM, and the other wire to terminal SW on terminal block 1 (TB1) located on the cover of the space temperature sensor using a 20 AWG twisted 3-conductor cable rated for the application.
2.Connect the other ends of the wires to terminals 1, 2, and 3 on TB3 located in the unit main control box. The wire from terminal SW MUST be connected to terminal 3.
NOTE: Either the T55 or the T56 sensor must be connected for CV applications to function properly.
SPACE TEMPERATURE AVERAGING Ð Applications that require averaging using multiple space temperature sensors can be satis®ed using either 4 or 9 sensors as shown in Fig. 14.
NOTE: Only Carrier sensors may be used for standard T55 space averaging. Sensors must be used in multiples of 1, 4, and 9 only, with total sensors wiring not to exceed 1000 ft. However, space temperature reset can be accomplished with only one sensor.
NOTE: Do not use T56 sensors for space temperature averaging because the 5 degree offset function will not work in a multiple sensor application.
HEAT INTERLOCK RELAY (VAV Units Only Ð Not Necessary For Digital Air Volume Applications) Ð Variable air volume (VAV) units using optimal start (morning warm-up) and/or occupied heating require that room terminals be controlled to the fully open position when the unit goes into heating mode. The HIR (Heat Interlock Relay) function is provided for this control on DSIO no. 2, channel 60. When the unit goes into heating mode, the HIR is energized to provide switch closure or opening (depending on how the ®eldsupplied power source is set up) to open the room terminals. The ®eld connections for the HIR are: Normally Closed, terminals 8 and 10 on TB3; and Normally Open, terminals 8 and 9 on TB3. See Fig. 15.
OPTION AND ACCESSORY CONTROL WIRING Ð The 48/50MP units may be used in applications with additional control features, options, or accessories. Refer to the Controls and Troubleshooting manual for more information concerning installation and con®guration of options and accessories. Figures 15 to 29 contain wiring information on the following features:
·heat interlock relay (Fig. 15)
·differential enthalpy sensor (Fig. 16)
