FEATURES All Series 20 J**DJ models are available with a wide variety of factory-mounted options such as stainless steel heat exchangers, phase monitor, dirty filter switch, and coil guard to make them suitable for almost every application. All units are self-contained and assembled on full perimeter base rails with holes in the four corners for overhead rigging. Every unit is completely piped, wired, charged and tested at the factory to simplify the field installation and to provide years of dependable operation. All models (including those with an economizer) are suitable for either bottom or horizontal duct connections. Models with factory installed power exhaust are suitable for bottom duct connections only. For bottom duct, you remove the sheet metal panels from the supply and return air openings through the base of the unit. For horizontal duct, you replace the supply and return air panels on the rear of the unit with a side duct flange accessory. All models are available with these “factory mounted” outdoor air damper options: • Single enthalpy economizer with or without power exhaust • BAS-ready economizer with or without power exhaust • Motorized outdoor air damper • Barometric Relief Damper A fixed outdoor air intake assembly will be shipped in the return air compartment of all units ordered without an econo- mizer or motorized outdoor air damper option. The assembly includes a rain hood with a damper that can be set for 10, 15 or 25% outdoor air. With bottom duct connections, the intake damper assembly should be mounted over the opening in the return air panel. With horizontal ductwork, it should be mounted on the return air duct. All supply air blowers are equipped with a belt drive that can be adjusted to meet the exact requirements of the job. A high static drive option is available for applications with a higher CFM and/or static pressure requirement. A variable air vol- ume (VAV) option using a variable frequency drive is available for applications requiring a constant supply duct pressure. A differential pressure transducer is used to monitor supply duct static pressure and return a speed reference signal to the VFD to control the output of the indoor blower motor. All compressors include scroll compressors and internal pres- sure relief. Every refrigerant circuit includes an expansion valve, a liquid line filter-drier, a discharge line high pressure switch and a suction line with a freezestat and low pressure/ loss of charge switch to protect all system components. A hot gas bypass option, consisting of an adjustable compressor discharge bypass valve, is available for low cooling load applications. • Advanced Controls - Unit control boards have stan- dardized a number of features previously available only as options or by utilizing additional controls. • Low Ambient - An integrated low-ambient control allows all units to operate in the cooling mode down to 0ºF outdoor ambient without additional assis- tance. Optionally, the control board can be pro- grammed to lockout the compressors when the outdoor air temperature is low or when free cooling is available. • Anti-Short Cycle Protection - To aid compressor life, an anti-short cycle delay is incorporated into the standard controls. Compressor reliability is further ensured by programmable minimum run times. For testing, the anti short cycle delay can be temporarily overridden with the push of a button. • Lead-Lag - An integrated Lead-Lag option allows equal run time hours on all compressors, thereby extending the life of all compressors. This option is selectable on the unit control board. • Fan Delays - Fan on and fan off delays are fully pro- grammable. Furthermore, the heating and cooling fan delay times are independent of one another. All units are programmed with default values based upon their configuration of cooling and heat. • Safety Monitoring - The control board monitors the high and low-pressure switches, the freezestats, the gas valve, if applicable, and the temperature limit switch on gas and electric heat units. The unit con- trol board will alarm on ignition failures, compressor lockouts and repeated limit switch trips. • Nuisance Trip Protection and Strikes - To prevent nuisance trouble calls, the control board uses a “three times, you’re out” philosophy. The high and low-pressure switches and the freezestats must trip three times within two hours before the unit control board will lock out the associated compressor. • On Board Diagnostics - Each alarm will energize a trouble light on the thermostat, if so equipped, and flash an alarm code on the control board LED. Each high and low-pressure switch alarm as well as each freezestat alarm has its own flash code. The control board saves the five most recent alarms in memory, and these alarms can be reviewed at any time. Alarms and programmed values are retained through the loss of power. All units have long lasting powder paint cabinets with 750 hour salt spray test approval under ASTM-B117 procedures. All models are CSA approved. • Warranty - All models include a one-year limited parts warranty on the complete unit. Compressors and electric heater elements carry a five-year warranty. Gas heat exchangers carry a 10-year parts warranty. • Gas Heat Operation - All gas heat units are built with two heating sections for two equal stages of capacity control. Each section includes a durable heat exchanger

5 with aluminized steel or optional stainless steel tubes, a redundant gas valve, spark ignition, power venting, an ignition module for 100% shut-off and all of the safety controls required to meet the latest ANSI standards. The gas supply piping can be routed into the heating compartment through a hole in the base pan of the unit or through a knockout in the piping panel on the front of the unit. • Electric Heat Operation - All electric heat models (fac- tory installed only) are wired for a single power source and include a bank of nickel chromium elements mounted at the discharge of the supply air blower to pro- vide a high velocity and uniform distribution of air across the heating elements. Every element is fully protected against excessive current and temperature by fuses and two thermal limit switches. The power supply wiring can be routed into the control box through a threaded pipe connection in the base pan of the unit or through a knockout in the wiring panel on the front of the unit. FACTORY-INSTALLED OPTIONS • SINGLE INPUT ELECTRONIC ENTHALPY ECONO- MIZERS - Includes a slide-in / plug-in damper assembly with fully modulating spring-return motor actuator capa- ble of introducing up to 100% outdoor air with nominal 1% leakage type dampers. The enthalpy system contains one sensor that monitors the outdoor air and determines when the air is cool enough and dry enough to provide free cooling. The rainhood is painted to match the basic unit and must be field-assembled before installing. • BAS-READY ECONOMIZER - Includes a slide-in / plug- in damper assembly with fully modulating spring-return motor actuator with zero to 95-degree rotation capable of introducing up to 100% outdoor air with nominal 1% leak- age type dampers. Actuator requires 2-10 VDC input from an external source, such as a field-installed or factory-installed BAS controller. BAS-ready actuators have an adjustable auxil- iary end-switch for optional power exhaust control. For units with optional VAV control, a factory-installed, dry bulb sensor determines if outdoor air temperature is low enough to provide free-cooling operation. (Field- installed humidity sensors for either outdoor air or out- door & return air streams are available for single enthalpy and differential enthalpy configurations, respec- tively). The rainhood is painted to match the basic unit and must be field-assembled before installing. FIGURE 1 - UNIT CUTAWAY UNIT

• POWER EXHAUST - Our economizer options are avail- able with power exhaust. Whenever the outdoor air intake dampers are opened for free cooling, the exhaust fan will be energized to prevent the conditioned space from being over-pressurized during economizer opera- tion. BAS-ready economizer actuators have an adjust- able auxiliary end-switch to provide a range of damper positions available to energize power exhaust. The exhaust fan, motor and controls are installed and wired at the factory. The rain hood must be assembled and installed in the field. The power exhaust option can only be used on bot- tom duct configurations. • MOTORIZED OUTDOOR AIR INTAKE DAMPER - Includes a slide-in / plug-in damper assembly with a 2- position, spring return motor actuator which opens to a pre-set position whenever the supply air blower is oper- ating and will drive fully closed when the blower unit shuts down. The rain hood is painted to match the basic unit and must be field assembled before installing. • BAROMETRIC RELIEF DAMPER - This damper option can be used to relieve internal building air pressure on units with an economizer without power exhaust. This accessory includes a rain hood, a bird screen and a fully assembled damper. With bottom duct connections, the damper should be mounted over the opening in the return air panel. With horizontal ductwork, the accessory should be mounted on the return air duct. • PHENOLIC COATED EVAPORATOR AND CON- DENSER COILS - Special coating process that utilizes Technicoat 10-1" processes. Coating is applied by total immersion of the complete coil for maximum protection. • ELECTRIC HEATERS wired for single point power sup- ply. These nickel chromium heater elements are pro- vided with limit and automatic reset capability to prevent operation at excessive temperatures. • VARIABLE AIR VOLUME (VAV) - A factory-installed variable frequency drive (VFD), mounted in the Blower Access compartment, is used to control the speed of the indoor blower motor in order to maintain a constant static pressure in the supply duct. A pressure transducer and VAV control board are mounted inside the control box. The drive comes completely wired and pre-programmed from the factory. An optional, factory-installed manual bypass switch available with factory-installed VFD can be found in the Blower Motor Access compartment. The switch can be used to either route power to the VFD for modulating control of the blower motor, to bypass the drive and oper- ate the motor at full speed, or to power the drive (and not the motor) for diagnostic purposes. Due to space limitations, VAV is not available with any of the factory-installed BAS options described below, but is available with ‘BAS-ready’ models. Terminal blocks are provided in the control box for field wiring of the cus- tomer-installed BAS. A ‘VFD-ready’ option provides the provisions for a cus- tomer-installed drive. The unit comes with a mounting bracket installed in the Blower Access compartment which may accommodate other vendor’s drives depend- ing on their size. In order to utilize the unit’s mounting bracket, the maximum recommended drive dimensions are as follows: For 5-hp motor applications ........................13” H x 6” W x 7” D For 7.5 thru 15-hp motor applications.........13” H x 8” W x 8” D If the drive will not fit in the allotted space, then it will have to be mounted elsewhere; either within the building on a perpendicular wall which is not subjected to exces- sive temperature, vibration, humidity, dust, corrosive gas, explosive gas, etc., or within an appropriate enclo- sure rated for outside installation to safeguard against moisture, dust and excessive heat. A terminal block located in the control box is provided for field connection of the VFD controls. • HOT GAS BYPASS - To allow for low cooling load oper- ation, a direct-acting pressure-modulating bypass control valve installed on the system #1 discharge line is used to divert high temperature, high pressure refrigerant around the TXV in order to maintain a desired minimum evapo- rator pressure. HGBP is standard on all units with VAV and optional with CV units. • FILTER OPTIONS - Standard units are shipped with 2” throw-away filters installed. 2” pleated and 4” pleated fil- ters are offered as a factory installed option. • CONVENIENCE OUTLET - This 110 volt outlet can be “powered” by the unit with a stepdown transformer or you may order the unit with a “non-powered” conve- nience outlet that can be wired in the field. • DISCONNECT SWITCH - For gas heat units and cooling units with electric heat, a HACR breaker sized to the unit is provided. For cooling only units, a switch sized to the largest electric heat available for the particular unit is provided. Factory installed option only. • DOUBLE WALL CONSTRUCTION - Optional double wall construction is available to provide smooth inner surfaces for easy and effective cleaning to reduce risk of dirt and bacterial accumulation. Fiberglass insulation is sandwiched between heavy gauge steel sheets to form a durable, rigid casing to withstand higher working pres- sures and impact forces. The heavy-duty construction provides excellent acoustic and thermal insulation and eliminates erosion of insulation material and contamina- tion of the air stream.

7 • SMOKE DETECTORS - (supply air & return air) The smoke detectors stop operation of the unit by interrupting power to the control board if smoke is detected within the air compartment. • COIL GUARD - Customers can purchase a coil guard kit to protect the condenser coil from damage.

The capacities are gross ratings. For net capacity, deduct air blower motor, MBh = 3.415 x kW. Refer to the appropriate Blower Performance table for the kW of the supply air blower motor. 2. These ratings include the condenser fan motors (total 1 kW) and the compressor motors but not the supply air blower motor.

CFM, STATIC PRESSURE, AND POWER - ALTI- TUDE AND TEMPERATURE CORRECTIONS The information below should be used to assist in application of product when being applied at altitudes at or exceeding 1000 feet above sea level. The air flow rates listed in the standard blower performance tables are based on standard air at sea level. As the altitude or temperature increases, the density of air decreases. In order to use the indoor blower tables for high altitude applica- tions, certain corrections are necessary. A centrifugal fan is a "constant volume" device. This means that, if the rpm remains constant, the CFM delivered is the same regardless of the density of the air. However, since the air at high altitude is less dense, less static pressure will be generated and less power will be required than a similar application at sea level. Air density correction factors are shown in Table 8 and Figure 2. The examples below will assist in determining the airflow per- formance of the product at altitude. Example 1: What are the corrected CFM, static pressure, and BHP at an elevation of 5,000 ft. if the blower performance data is 6,000 CFM, 1.5 IWC and 4.0 BHP? Solution: At an elevation of 5,000 ft the indoor blower will still deliver 6,000 CFM if the rpm is unchanged. However, Table 8 must be used to determine the static pressure and BHP. Since no temperature data is given, we will assume an air temperature of 70°F. Table 8 shows the correction factor to be 0.832. Corrected static pressure = 1.5 x 0.832 = 1.248 IWC Corrected BHP = 4.0 x 0.832 = 3.328 Example 2: A system, located at 5,000 feet of elevation, is to deliver 6,000 CFM at a static pressure of 1.5". Use the unit blower tables to select the blower speed and the BHP requirement. Solution: As in the example above, no temperature informa- tion is given so 70°F is assumed. The 1.5" static pressure given is at an elevation of 5,000 ft. The first step is to convert this static pressure to equivalent sea level conditions. Sea level static pressure = 1.5 / .832 = 1.80" Enter the blower table at 6000 sCFM and static pressure of 1.8". The rpm listed will be the same rpm needed at 5,000 ft. Suppose that the corresponding BHP listed in the table is 3.2. This value must be corrected for elevation. BHP at 5,000 ft = 3.2 x .832 = 2.66 TABLE 8: ALTITUDE CORRECTION FACTORS AIR TEMP ALTITUDE (FEET) 0 1000 2000 3000 4000 5000 6000 7000 8000 9000 10000 40 1.060 1.022 0.986 0.950 0.916 0.882 0.849 0.818 0.788 0.758 0.729 50 1.039 1.002 0.966 0.931 0.898 0.864 0.832 0.802 0.772 0.743 0.715 60 1.019 0.982 0.948 0.913 0.880 0.848 0.816 0.787 0.757 0.729 0.701 70 1.000 0.964 0.930 0.896 0.864 0.832 0.801 0.772 0.743 0.715 0.688 80 0.982 0.947 0.913 0.880 0.848 0.817 0.787 0.758 0.730 0.702 0.676 90 0.964 0.929 0.897 0.864 0.833 0.802 0.772 0.744 0.716 0.689 0.663 100 0.946 0.912 0.880 0.848 0.817 0.787 0.758 0.730 0.703 0.676 0.651
