Refer to the NFPA 54/ANSI Z223.1 NFGC latest edition (in Canada, CAN/CSA B149.1). In the ab- sence of local building codes, adhere to the following pertinent recommendations: • Avoid low spots in long runs of pipe. Grade all pipe 1/4-in. per every 15 ft (7 mm per every 5 m) to prevent traps. Grade all horizontal runs downward to risers. Use risers to connect to heating section and to meter. • Protect all segments of piping system against physical and thermal damage. Support all piping with appropriate straps, hangers, etc. Use a minimum of one hanger every 6 ft (1.8 m). For pipe sizes larger than 1/2-in., follow recommendations of national codes. • Apply joint compound (pipe dope) sparingly and only to male threads of joint when making pipe connections. Use only pipe dope that is resistant to action of liquefied petro- leum gases as specified by local and/or national codes. If using PTFE (Teflon') tape, ensure the material is Double Density type and is labeled for use on gas lines. Apply tape per manufacturer's instructions. • Pressure -test all gas piping in accordance with local and national plumbing and gas codes before connecting piping to unit. NOTE: Pressure test the gas supply system after the gas supply piping is connected to the gas valve. The supply piping must be disconnected from the gas valve during the testing of the piping systems when test pressure is in excess of 0.5 psig (3450 Pa). Pres- sure test the gas supply piping system at pressures equal to or less than 0.5 psig (3450 Pa). The unit heating section must be isolated from the gas piping system by closing the external main manual shutoff valve and slightly opening the ground joint union. Check for gas leaks at the field -installed and factory -installed gas lines after all piping connections have been completed. Use soap -and -water solution (or method specified by local codes and/or regulations). 0 WARNING Failure to follow this warning could result in personal injury, death and/or property damage. • Connect gas pipe to unit using a backup wrench to avoid damaging gas controls. • Never purge a gas line into a combustion chamber. • Never test for gas leaks with an open flame. Use a commercially available soap solution made specifically for the detection of leaks to check all connections. • Use proper length of pipe to avoid stress on gas control manifold. NOTE: If orifice hole appears damaged or it is suspected to have been redrilled, check orifice hole with a numbered drill bit of cor- rect size. Never redrill an orifice. A burr -free and squarely aligned orifice hole is essential for proper flame characteristics. See Fig. 23. Fig. 23 — Orifice Hole Step 12 — Install External Condensate Trap and Line The unit has one 3/4-in. condensate drain connection on the end of the condensate pan and an alternate connection on the bottom. See Fig. 24. Unit airflow configuration does not determine which drain connection to use. Either drain connection can be used with vertical or horizontal applications. When using the standard side drain connection, ensure the red plug in the alternate bottom connection is tight. Do this before set- ting the unit in place. The red drain pan can be tightened with a 1/2- in. square socket drive extension. To use the alternate bottom drain connection, remove the red drain plug from the bottom connection (use a 1/2-in. square socket drive extension) and install it in the side drain connection. The piping for the condensate drain and external trap can be com- pleted after the unit is in place. See Fig. 25. 1.

Disconnect sizing data is provided on the unit informative plate. Locate on unit cabinet or within sight of the unit per national or local codes. Do not cover unit informative plate if mounting the disconnect on the unit cabinet. ALL UNITS All field wiring must comply with NEC and all local codes. Size wire based on MCA (Minimum Circuit Amps) on the unit infor- mative plate. See Fig. 26 and the unit label diagram for power wir- ing connections to the unit power terminal blocks and equipment ground. Maximum wire size is #2ga AWG (copper only) per pole on contactors. See Fig. 26 and unit label diagram for field power wiring connections. Provide a ground fault and short circuit over -current protection de- vice (fuse or breaker) per NEC Article 440 (or local codes). Refer to unit informative data plate for MOCP (Maximum Over -Current Protection) device size. All units except 208/230v units are factory wired for the voltage shown on the nameplate. If the 2081230v unit is to be connected to a 208v power supply, the control transformer must be rewired by moving the black wire with the 1/4-in. female spade connector from the 230v connection and moving it to the 200v 1/4-in. male termi- nal on the primary side of the transformer. Refer to unit label dia- gram for additional information. Field power wires will be 18 RECEIVED Jun 10 2921 connected at line -side prrg, ors on the power terminal block or at factory -installed 8,Vf1Wed disconnect. Voltage to compressor terminals during operation must be within voltage range indicated on unit nameplate. On 3-phase units, volt- ages between phases must be balanced within 2% and the current within 10%. Use the formula shown in the example below to de- termine the percent of voltage imbalance. Operation on improper line voltage or excessive phase imbalance constitutes abuse and may cause damage to electrical components. Such operation would invalidate any applicable Carrier warranty. % Voltage = 100 x max voltage deviation from average voltage Imbalance average voltage Example: Supply voltage is 230-3-60 A R c AB=224v BC=231v MOTOR AC = 226 v Average Voltage = (224 + 231 + 226) _ 681 _ 227 Determine maximum deviation from average voltage. (AB) 227-224 = 3 v (BC) 231-227 = 4 v (AC) 227-226 = 1 v Maximum deviation is 4 v. Determine percent of voltage imbalance. % Voltage Imbalance = 100x 227 = 1.78% This amount of phase imbalance is satisfactory as it is below the maxi- mum allowable 2%. IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.

Check for full closing and latching. COVER - WHILE -IN -USE WEATHERPROOF GFCI RECEPTACLE -� NOT INCLUDED m i a m J� GASKET BASEPL/ATE FOR GFCI RECEPTACLE Fig. 33 — Weatherproof Cover Installation Non -Powered Convenience Outlet This type requires the field installation of a general-purpose 125-v 15A circuit powered from a source elsewhere in the building. Ob- serve national and local codes when selecting wire size, fuse or breaker requirements, and disconnect switch size and location. Route 125v power supply conductors into the bottom of the utility box containing the duplex receptacle. Unit -Powered Convenience Outlet A unit -mounted transformer is factory -installed to step down the main power supply voltage to the unit to 115v at the duplex recep- tacle. This option also includes a manual switch with fuse, located in a utility box and mounted on a bracket behind the convenience outlet; access is through the unit's control box access panel. See Fig. 30. The primary leads to the convenience outlet transformer are not factory -connected. Selection of primary power source is a custom- er option. If local codes permit, the transformer primary leads can be connected at the line -side terminals on the unit -mounted non - fused disconnect switch; this will provide service power to the unit when the unit disconnect switch is open. Other connection meth- ods will result in the convenience outlet circuit being de -energized when the unit disconnect switch is open. See Fig. 34.

Test the GFCI receptacle by pressing the TEST button on the face of the receptacle to trip and open the receptacle. Check for proper grounding wires and power line phasing if the GFCI receptacle does not trip as required. Press the RESET button to clear the tripped condition. Using Unit -Mounted Convenience Outlets Units with unit -mounted convenience outlet circuits will often re- quire that two disconnects be opened to de -energize all power to the unit. Treat all units as electrically energized until the conve- nience outlet power is also checked and de-energization is con- firmed. Observe National Electrical Code Article 210, Branch Cir- cuits, for use of convenience outlets. 20 1. Bussman and Fusetron are trademarks of Cooper Technologies Company. RECEIVED FACTORY -OPTION T u�- �E CONNECTIONS (ELEC- TRICAL CONNECT fi�TMENTVICE9 This service connection kit consists of a 1/2-in. NPT gas adapt- er fitting (brass), a 1/2-in. electrical bulkhead connector, and a 3/4-in. electrical bulkhead connector, all factory -installed in the embossed (raised) section of the unit basepan in the condenser section. The 3/4-in. bulkhead connector enables the low -voltage control wires to pass through the basepan. The 1/2-in. electrical bulkhead connector allows the high -voltage power wires to pass through the basepan. See Fig. 18 on page 15. NOTE: If electrical connections are not going to occur at this time, tape or otherwise cover the fittings so that moisture does not get into the building or conduit in the interim. Check tightness of connector lock nuts before connecting electri- cal conduits. Field -supplied and field -installed liquid tight conduit connectors and conduit may be attached to the connectors on the basepan. Pull correctly rated high voltage and low voltage through appro- priate conduits. Connect the power conduit to the internal discon- nect (if unit is so equipped) or to the external disconnect (through unit side panel). A hole must be field cut in the main control box bottom on the left side so the 24-v control connections can be made. Connect the control power conduit to the unit control box at this hole. UNITS WITHOUT THRU-BASE CONNECTIONS (ELECTRICAL CONNECTIONS) I. Install power wiring conduit through side panel openings. Install conduit between disconnect and control box. 2. Install power lines to terminal connections as shown in Fig. 26 on page 17. FIELD CONTROL WIRING The 48FC unit requires an external temperature control device. This device can be a thermostat (field -supplied) or a SystemVuTM controller (available as factory -installed option for use on a Carrier Comfort Network® or as a stand alone control) or the RTU Open Controller for Building Management Systems using non-CCN protocols (RTU Open controller is available as a factory -installed option only). THERMOSTAT Install a Carrier -approved accessory thermostat according to in- stallation instructions included with the accessory. For complete economizer function, select a two -stage cooling thermostat. Lo- cate the thermostat accessory on a solid wall in the conditioned space to sense average temperature in accordance with the ther- mostat installation instructions. Typical low -voltage connections are shown in Fig. 35. If the thermostat contains a logic circuit requiring 24-v power, use a thermostat cable or equivalent single leads of different colors with minimum of seven leads. If the thermostat does not require a 24-v source (no "C" connection required), use a thermostat cable or equivalent with minimum of six leads. Check the thermostat in- stallation instructions for additional features which might require additional conductors in the cable. For wire runs up to 50 ft (15 m), use no. 18 AWG (American Wire Gage) insulated wire [95°F (35°C) minimum]. For 50 to 75 ft (15 to 23 m), use no. 16 AWG insulated wire [95°F (35°C) minimum]. For over 75 ft (23 m), use no. 14 AWG insulated wire [95°F (35°C) minimum]. Wire sizes larger than no. 18 AWG cannot be directly connected to the thermostat and will require a junction box and splice at the thermostat.

The IGC control board uses a flue gas pressure switch that senses pres- sure drop in the heat exchanger due to the combustion inducer. See Fig. 44. FLUE GAS PRESSURE SWITCH FLUE GAS PRESSURE SENSETUBE VI Fig. 44 — Flue Gas Pressure Switch and Pressure Sense Tube (Typical Location) LOCKING TAB CONNEC' When the thermostat calls for heating, power is sent to W on the Integrated Gas Controller (IGC) board. An LED (light emitting di- ode) on the IGC board turns on and remains on during normal op- eration. A check is made to ensure that the rollout switch and limit switch are closed, and that the pressure switch is open. If the check was successful, the induced draft motor is energized. When the pressure in the heat exchanger is low enough to close the pressure switch, the ignition activation period begins. Once ignition occurs, the IGC board will continue to monitor the condition of the rollout switch, the limit switches, the pressure switch, and the flame sen- sor. Assuming the unit is controlled through a room thermostat set for "fan auto," 45 seconds after ignition occurs, the indoor fan mo- tor will energize, and the outdoor air dampers will open to their minimum position. If the "over temperature limit" opens prior to the start of the indoor fan blower, the IGC will shut down the burners, and the control will shorten the 45 second delay to 5 seconds less than the time to trip the limit. For example, if the limit trips at 37 seconds, the control will change the "fan on delay" from 45 seconds to 32 seconds. Once the "fan on delay" has been modified, it will not change back to 45 seconds unless power is re- set to the control. On units with 2 stages of heat, W2 closes and initiates power to the second stage of the main gas valve when ad- ditional heat is required. When the thermostat is satisfied, W 1 and W2 open and the gas valve closes, interrupting the flow of gas to the main burners.

The W7220 can be config- ured with optional sensors. Fig. 47 — W7220 Economizer Module The W7220 economizer module can be used as a stand-alone economizer module wired directly to a commercial set -back space thermostat and sensors to provide outside air dry-bulb economizer control. The W7220 economizer module can be connected to optional sensors for single or differential enthalpy control. The W7220 economizer module provides power and communications for the sensors. The W7220 economizer module automatically detects sensors by polling to determine which sensors are present. If a sensor loses communications after it has been detected, the W7220 economizer controller indicates a device fail error on its LCD. SYSTEM COMPONENTS The EconoMi$er X system includes an economizer module, 20k mixed air sensor, damper actuator, and either a 20k outdoor air temperature sensor or S-Bus enthalpy sensors. Economizer Module The module is the core of the EconoMi$er X system. The module is mounted in the unit's control box, and includes the user inter- face for the system. The W7220 economizer module provides the basic inputs and outputs to provide simple economizer control. When used with the optional sensors, the economizer module pro- vides more advanced economizer functionality. S-Bus Enthalpy Control Sensors The sensor is a combination temperature and humidity sensor which is powered by and communicates on the S-Bus. Up to three sensors may be configured with the W7220 economizer module. CO2 Sensor (optional) The sensor can be added for Demand Controlled Ventilation (DCV). SPECIFICATIONS W7220 Economizer Module The module is designed for use with 2 to 10 Vdc or bus communi- cating actuator. The module includes terminals for CO2 sensor, Mixed Air sensor, and an Outdoor Dry Bulb sensor. Enthalpy and other options are available with bus sensors. User Interface Provides status for normal operation, setup parameters, checkout tests, and alarm and error conditions with a 2-line 16 character LCD display and four button keypad.

The W7220 controller has the capability to work with a system us- ing a 2-speed supply fan. The W7220 does not control the supply directly but uses the following input status to determine the speed of the supply fan and controls the OA damper to the required posi- tion, see Table 15. Table 15 — Fan Speed STATE FAN SPEED OCC Low Y1 Low Y2 High W High The W (heating mode) is not controlled by the W7220 but it re- quires the status to know where to position the OA damper for minimum position for the fan speed. The 2 speed fan delay is available when the system is programmed for 2 speed fan (in the System Setup menu item). The 2 speed fan delay is defaulted to 5 minutes and can be changed in the Ad- vanced Setup menu item. When the unit has a call for Y1 In and in the free cooling mode and there is a call for Y2 In, the 2-speed fan delay starts and the OA damper will modulate 100% open, the supply fan should be set to high speed by the unit controller. After the delay, one of two actions will happen: • The Y2 In call will be satisfied with the damper 100% open and fan on high speed and the call will turn off OR If the call for additional cooling in the space has not been satisfied then the first stage of mechanical cooling will be enabled through Y1 Out or Y2 Out.

On single phase units, the unit control board (UCB) will reduce the fan speed during heating when the configured fan speed is set outside the optimized heating speed window. If the job site application forces this reduction in fan speed during heat, the economizer FAN TYPE must be set to keep the appropriate outside air intake. On single phase 48FC 3 to 5 ton units, if reduced the heating fan speed is lower than the cooling speed and the economizer FAN TYPE needs to be set to 2SP H/C (2 speed Heat/Cool). This indi- cates that the heating and vent mode fan speed is less than then cooling mode fan speed in the unit.
