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 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.

Recognize safety information. This is the safety--alert symbol

. When you see this symbol on the furnace and in instructions or manuals, be alert to the potential for personal injury.

Understand the signal words DANGER, WARNING, and CAUTION. These words are used with the safety--alert symbol. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies a hazard which could result in personal injury or death. CAUTION is used to identify unsafe practices which may result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation.

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could cause personal injury or death.

Before performing service or maintenance operations on unit, turn off main power switch to unit and install lockout tag. Ensure electrical service to rooftop unit agrees with voltage and amperage listed on the unit rating plate.

WARNING

Page 2

FIRE, EXPLOSION HAZARD

Failure to follow this warning could death and/or property damage.

Disc onnect gas piping from unit when leak testing at pressure greater than psig will cause gas valve damage resulting in hazardous condition. If gas va lve is subjecte d to pressure greater than

/2psig, it must be replaced before use. When pressure testing field-supplied gas piping at pressures of less, a uni t connected to such piping must be i solated by manual l y closing the gas valve(s).

INSTALLATION

Unit is shipped in the vertical discharge configuration. To convert to horizontal discharge application, remove duct opening covers. Using the same screws, install covers on duct openings in

48HE,HJ

basepan of unit with insulation-side down. Seals around openings must be tight. (See Fig. 1.)

Fig. 1 --- Horizontal Conversion Panels

Step 1 —Provide Unit Support

CURB

ROOF

Assemble and install accessory roof curb in accordance with instructions shipped with curb. (See Fig. 2.) Install insulation, cant strips, roofing felt, and counter flashing as shown. Ductwork must be attached to curb, not to the unit. If electric control power or gas service is to be routed through the basepan, attach the accessory thru-the-bottom service connections to the basepan in accordance with the accessory installation instructions. Connections must be installed before unit is set on roof curb.

IMPORTANT: The gasketing of the unit t o the roof curb is critical for a watertight seal. Install gasket supplied with the roof curb as shown in Fig. 2. Improperl y applied gasket can result in air leaks and poor unit performanc e.

Curb should be level. Unit leveling tolerances are shown in Fig.

3. This is necessary for unit drain to function properly. Refer to Accessory Roof Curb Installation Instructions for additional information as required.

SLAB MOUNT (Horizontal Units Only)

Provide a level concrete slab that extends a minimum of 6 in. beyond unit cabinet. Install a gravel apron in front of

C06108

condenser-coil air inlet to prevent grass and foliage from obstructing airflow.

NOTE: Horizontal units may be installed on a roof curb if required.

ALTERNATE UNIT SUPPORT

When the curb or adapter cannot be used, support unit with sleeper rails using unit curb or adapter support area. If sleeper rails cannot be used, support the long sides of the unit with a minimum of 3 equally spaced 4-in. x 4-in. pads on each side.

Step 2 —Field Fabricate Ductwork

Secure all ducts to roof curb and building structure on vertical discharge units. Do not connect ductwork to unit. For horizontal applications, field-supplied isolation flanges should be attached to horizontal discharge openings and all ductwork should be secured to the flanges. Insulate and weatherproof all external ductwork, joints, and roof openings with counter flashing and mastic in accordance with applicable codes.

Ducts passing through an unconditioned space must be insulated and covered with a vapor barrier.

If a plenum return is used on a vertical unit, the return should be ducted through the roof deck to comply with applicable fire codes.

A minimum clearance is not required around ductwork. Cabinet return-air static pressure (a negative condition) shall not exceed

0.35 in. wg with economizer or 0.45 in. wg without economizer. These units are designed for a minimum continuous return-air

temperature in heating of 50_F (dry bulb), or an intermittent operation down to 45_F (dry bulb), such as when used with a night setback thermostat.

To operate at lower return-air temperatures, a field-supplied outdoor air temperature control must be used to initiate both stages of heat when the temperature is below 45_F. Indoor comfort may be compromised when these lower air temperatures are used with insufficient heating temperature rise.

Step 3 —Install External Trap for Condensate Drain

The unit’s bottom and side of the unit. Unit discharge connections do not determine the use of drain connections; either drain connection can be used with vertical or horizontal applications.

When using the standard side drain connection, ensure the plug (Red) in the alternate bottom connection is tight before installing the unit.

To use the bottom drain connection for a roof curb installation, relocate the factory-installed plug (Red) from the bottom connection to the side connection. The center drain plug looks like a star connection, however it can be removed with a socket drive extension. (See Fig. 4.) The piping for the condensate drain and external trap can be completed after the unit is in place.

All units must have an external trap for condensate drainage. Install a trap 4-in. deep and protect against freeze-up. If drain line is installed downstream from the external trap, pitch the line away from the unit at 1 in. per 10 ft of run. Do not use a pipe size smaller than the unit connection (

Step 4 —Rig a nd Place Unit

Inspect unit for transportation damage, and file any claim with transportation agency. Keep unit upright and do not drop. Spreader bars are not required if top crating is left on unit, and rollers may be used to move unit across a roof. Level by using unit frame as a reference. See Table 1 and 2 and Fig. 6 for additional information. Operating weight is shown in Table 1 and 2 and Fig. 6.

premierlink

 control

The PremierLink controller is compatible with Carrier Comfort NetworkR (CCN) devices. This control is designed to allow users the access and ability to change factory--defined settings, thus expanding the function of the standard unit control board. Carrier’s diagnostic standard tier display tools such as Navigatort or Scrolling Marquee can be used with the PremierLink controller.

The PremierLink controller (see Fig. 24 and 25) requires the use of a Carrier electronic thermostat or a CCN connection for time broadcast to initiate its internal timeclock. This is necessary for broadcast of time of day functions (occupied/unoccupied). No sensors are supplied with the field-- mounted PremierLink control. The factory--installed PremierLink control includes only the supply-- air temperature (SAT) sensor and the outdoor air temperature (OAT) sensor as standard. An indoor air quality (CO2) sensor can be added as an option. Refer to Table 5 for sensor usage. Refer to Fig. 26 for PremierLink controller wiring. The PremierLink control may be mounted in the control panel or an area below the control panel.

NOTE: PremierLink controller versions 1.3 and later are shipped in Sensor mode. If used with a thermostat, the PremierLink controller must be configured to Thermostat mode.

Install the Supply Air Temperature (SAT) Sensor

When the unit is supplied with a factory--mounted PremierLink control, the supply--air temperature (SAT) sensor (33ZCSENSAT) is factory-- supplied and wired. The wiring is routed from the PremierLink control over the control box, through a grommet, into the fan section, down along the back side of the fan, and along the fan deck over to the supply--air opening.

The SAT probe is wire--tied to the supply--air opening (on the horizontal opening end) in its shipping position. Remove the sensor for installation. Re-- position the sensor in the flange of the supply-- air opening or in the supply air duct (as required by local codes). Drill or punch a 1/2--in. hole in the flange or duct. Use two field--supplied, self--drilling screws to secure the sensor probe in a horizontal orientation.

NOTE: The sensor must be mounted in the discharge airstream downstream of the cooling coil and any heating devices. Be sure the probe tip does not come in contact with any of the unit or heat surfaces.

Outdoor Air Temperature Sensor (OAT)

When the unit is supplied with a factory-mounted PremierLink control and economizer, the outdoor-air temperature sensor (OAT) is factory-supplied and wired.

Install the Indoor Air Quality (CO

Mount the optional indoor air quality (CO

)Sensor

) sensor according to

manufacturer specifications. A separate field-supplied transformer must be used to power the

sensor.

Wire the CO

sensor to the COM and IAQI terminals of J5 on the

PremierLink controller. Refer to the PremierLink Installation, Start-up, and Configuration Instructions for detailed wiring and configuration information.

Enthalpy Sensors and Control

The enthalpy control (HH57AC077) is supplied as a field-installed accessory to be used with the EconoMi$er2 damper control option. The outdoor air enthalpy sensor is part of the enthalpy control. The separate field-installed accessory return air enthalpy sensor (HH57AC078) is required for differential enthalpy control.

NOTE: The enthalpy control must be set to the “D” setting for differential enthalpy control to work properly.

The enthalpy control receives the indoor and return enthalpy from the outdoor and return air enthalpy sensors and provides a dry contact switch input to the PremierLink controller. Locate the controller in place of an existing economizer controller or near the actuator. The mounting plate may not be needed if existing bracket is used.

A closed contact indicates that outside air is preferred to the return air. An open contact indicates that the economizer should remain at minimum position.

Outdoor Air Enthalphy Sensor/Enthalpy Controller (HH57AC077)

T o wire the out door air enthalpy sensor, perform the following (See Fig. 27 and 28):

NOTE: The outdoor air sensor can be removed from the back of the enthalpy controller and mounted remotely.

Outdoor Dry Bulb Changeover

The standard controller is shipped from the factory configured for outdoor dry bulb changeover control. The outdoor--air and supply-- air temperature sensors are included as standard. For this control mode, the outdoor temperature is compared to an adjustable set point selected on the control. If the outdoor-air temperature is above the set point, the EconoMi$er IV will adjust the outdoor-air dampers to minimum position. If the outdoor air temperature is below the set point, the position of the outdoor air dampers will be controlled to provide free cooling using outdoor air. When in this mode, the LED next to the free cooling set point potentiometer will be on. The changeover temperature set point is controlled by the free cooling set point potentiometer located on the control. (See Fig. 42.) The scale on the potentiometer is A, B, C, and D. See Fig. 43 for the corresponding temperature changeover values.

Differential Dry Bulb Control

For differential dry bulb control the standard outdoor dry bulb sensor is used in conjunction with an additional accessory dry bulb sensor (part number CRTEMPSN002A00). The accessory sensor must be mounted in the return airstream. (See Fig. 44.) Wiring is provided in the EconoMi$er IV wiring harness. (See Fig. 36.)

In this mode of operation, the outdoor-air temperature is compared to the return-air temperature and the lower temperature airstream is used for cooling. When using this mode of changeover control, turn the enthalpy setpoint potentiometer fully clockwise to the D setting. (See Fig. 42.)

Outdoor Enthalpy Changeover

For enthalpy control, accessory enthalpy sensor (part number HH57AC078) is required. Replace the standard outdoor dry bulb temperature sensor with the accessory enthalpy sensor in the same mounting location. (See Fig. 29.) When the outdoor air enthalpy rises above the outdoor enthalpy changeover set point, the outdoor-air damper moves to its minimum position. The outdoor

enthalpy changeover set point is set with the outdoor enthalpy set point potentiometer on the EconoMi$er IV controller. The set points are A, B, C, and D. (See Fig. 45.) The factory-installed 620-ohm jumper must be in place across terminals SR and SR+ on the EconoMi$er IV controller. (See Fig. 29 and 46.)

Page 26

Differential Enthalphy Control

For differential enthalpy control, the EconoMi$er IV controller uses two enthalpy sensors (HH57AC078 and CRENTDIF004A00), one in the outside air and one in the return air duct. The EconoMi$er IV controller compares the outdoor air enthalpy to the return air enthalpy to determine EconoMi$er IV use. The controller selects the lower enthalpy air (return or outdoor) for cooling. For example, when the outdoor air has a lower enthalpy than the return air, the EconoMi$er IV opens to bring in outdoor air for free cooling.

set point is set with the outdoor enthalpy set point potentiometer on the EconoMi$er IV controller. When using this mode of changeover control, turn the enthalpy setpoint potentiometer fully clockwise to the D setting.

Indoor Air Quality (IAQ) Sensor Input

The IAQ input can be used for demand control ventilation control based on the level of CO

measured in the space or return air

duct. Mount the accessory IAQ sensor according to manufacturer

specifications. The IAQ sensor should be wired to the AQ and AQ1 terminals of the controller. Adjust the DCV potentiometers to correspond to the DCV voltage output of the indoor air quality sensor at the user-determined set point. (See Fig. 47.)

If a separate field-supplied transformer is used to power the IAQ sensor, the sensor must not be grounded or the EconoMi$er IV control board will be damaged.

Exhaust Set Point Adjustment

The exhaust set point will determine when the exhaust fan runs based on damper position (if accessory power exhaust is installed). The set point is modified with the Exhaust Fan Set Point (EXH SET) potentiometer. (See Fig. 42.) The set point represents the damper position above which the exhaust fans will be turned on. When there is a call for exhaust, the EconoMi$er IV controller provides a 45  15 second delay before exhaust fan

Page 27

activation to allow the dampers to open. This delay allows the damper to reach the appropriate position to avoid unnecessary fan overload.

Minimum Position Control

There is a minimum damper position potentiometer on the EconoMi$er IV controller. (See Fig. 42.) The minimum damper position maintains the minimum airflow into the building during the occupied period.

When using demand ventilation, the minimum damper position represents the minimum ventilation position for VOC (volatile organic compound) ventilation requirements. The maximum demand ventilation position is used for fully occupied ventilation.

When demand ventilation control is not being used, the minimum position potentiometer should be used to set the occupied ventilation position. The maximum demand ventilation position should be turned fully clockwise.

Adjust the minimum position potentiometer to allow the minimum amount of outdoor air, as required by local codes, to enter the building. Make minimum position adjustments with at least 10_F temperature difference between the outdoor and return-air temperatures.

To determine the minimum position setting, perform the following procedure:

1. Calculate the appropriate mixed air temperature using the following formula:

100 100

+(TR

Thermostats

The EconoMi$er IV control works with conventional thermostats that have a Y1 (cool stage 1), Y2 (cool stage 2), W1 (heat stage

1), W2 (heat stage 2), and G (fan). The EconoMi$er IV control does not support space temperature sensors. Connections are made at the thermostat terminal connection board located in the main control box.

As an example, if local codes require 10% outdoor air during occupied conditions, outdoor-air temperature is 60_F, an d return-air temperature is 75_F.

(60 x .10) + (75 x .90) = 73.5_F

2. Disconnect the supply air sensor from terminals T and T1.

3. Ensure that the factory-installed jumper is in place across terminals P and P1. If remote damper positioning is being used, make sure that the terminals are wired according to Fig. 36 and that the minimum position potentiometer is turned fully clockwise.

4. Connect 24 vac across terminals TR and TR1.

5. Carefully adjust the minimum position potentiometer until the measured supply air temperature matches the calculated value.

6. Reconnect the mixed air sensor to terminals T and T1.

Remote control of the EconoMi$er IV damper is desirable when requiring additional temporary ventilation. If a field-supplied remote potentiometer (Honeywell part number S963B1128) is wired to the EconoMi$er IV controller, the minimum position of the damper can be controlled from a remote location.

To control the minimum damper position remotely, remove the factory-installed jumper on the P and P1 terminals on the EconoMi$er IV controller. Wire the field-supplied potentiometer to the P and P1 terminals on the EconoMi$er IV controller. (See Fig. 46.)

Occupancy Control

The factory default configuration for the EconoMi$er IV control is occupied mode. Occupied mode is provided by the black jumper from terminal TR to terminal N. When unoccupied mode is desired, install a field-supplied timeclock function in place of the jumper between TR and N. (See Fig. 36.) When the timeclock contacts are closed, the EconoMi$er IV control will be in occupied mode. When the timeclock contacts are open (removing the 24-v signal from terminal N), the EconoMi$er IV will be in unoccupied mode.

Typically the maximum ventilation rate will be about 5 to 10% more than the typical cfm required per person, using normal outside air design criteria.

Demand Controlled Ventilation (DCV)

When using the EconoMi$er IV for demand controlled ventilation, there are some equipment selection criteria which should be considered. When selecting the heat capacity and cool capacity of the equipment, the maximum ventilation rate must be evaluated for design conditions. The maximum damper position must be calculated to provide the desired fresh air.

A proportional anticipatory strategy should be taken with the following conditions: a zone with a large area, varied occupancy, and equipment that cannot exceed the required ventilation rate at design conditions. Exceeding the required ventilation rate means the equipment can condition air at a maximum ventilation rate that is greater than the required ventilation rate for maximum occupancy. A proportional-anticipatory strategy will cause the fresh air supplied to increase as the room CO even though the CO the CO

level reaches the set point, the damper will be at

set point has not been reached. By the time

level increases

maximum ventilation and should maintain the set point. In order to have the CO

sensor control the economizer damper in

this manner, first determine the damper voltage output for minimum or base ventilation. Base ventilation is the ventilation required to remove contaminants during unoccupied periods. The following equation may be used to determine the percent of outside-air entering the building for a given damper position. For best results there should be at least a 10 degree difference in outside and return-air temperatures.

Once base ventilation has been determined, set the minimum damper position potentiometer to the correct position.

The same equation can be used to determine the occupied or maximum ventilation rate to the building. For example, an output of 3.6 volts to the actuator provides a base ventilation rate of 5% and an output of 6.7 volts provides the maximum ventilation rate of 20% (or base plus 15 cfm per person). Use Fig. 44 to determine the maximum setting of the CO

sensor. For example,

a 1100 ppm set point relates to a 15 cfm per person design. Use the 1100 ppm curve on Fig. 47 to find the point when the CO sensor output will be 6.7 volts. Line up the point on the graph with the left side of the chart to determine that the range configuration for the CO

sensor should be 1800 ppm. The

EconoMi$er IV controller will output the 6.7 volts from the CO sensor to the actuator when the CO2concentration in the space is at 1100 ppm. The DCV set point may be left at 2 volts since the

sensor voltage will be ignored by the EconoMi$er IV

controller until it rises above the 3.6 volt setting of the minimum position potentiometer.

Once the fully occupied damper position has been determined, set the maximum damper demand control ventilation potentiometer to this position. Do not set to the maximum position as this can result in over-ventilation to the space and potential high-humidity levels.

Dehumidification of Fresh Air with DCV Control

Information from ASHRAE indicates that the largest humidity load on any zone is the fresh air introduced. For some applications, a device such as a 62AQ energy recovery unit is added to reduce the moisture content of the fresh air being brought into the building when the enthalpy is high. In most cases, the normal heating and cooling processes are more than adequate to remove the humidity loads for most commercial applications.

If normal rooftop heating and cooling operation is not adequate for the outdoor humidity level, an energy recovery unit and/or a dehumidification option should be considered.

Step 9 —Adjust Evaporator--Fan Speed

Adjust evaporator-fan speed to meet jobsite conditions. Tables 9 and 10 show fan rpm at motor pulley settings. Tables 11

and 15 show maximum amp draw of belt-drive motor. Table 14 shows sound data. Refer to Tables 16-35 for performance data. See Table 36 for accessory static pressure drop. See Fig. 48 for the Humidi-MiZer system static pressure drops.

Belt drive

motors

Fan motor pulleys are factory set for speed shown in Table 1 or 2. Check pulley alignment and belt tension prior to start-up.

To change fan speed:

1. Shut off the unit power supply and tag disconnect.

2. Loosen the belt by loosening the fan motor mounting nuts. (See Fig. 49.)

3. Loosen movable pulley flange setscrew. (See Fig. 50.)

4. Screw movable flange toward fixed flange to increase speed and away from fixed flange to decrease speed. Increasing fan speed increases load on motor. Do not exceed maximum speed specified in Table 1 or 2.

5. Set movable flange at nearest keyway of pulley hub and tighten setscrew. (See Table 1 or 2 for speed change for each full turn of pulley flange.)

6. Adjust belt tension and align gan and motor pulleys per guidance below.

To align fan and motor pulleys, loosen fan pulley setscrews and slide fan pulley along fan shaft. Make angular alignment by loosening motor from mounting.

Additional motor and fan alignment, as well as angular alignment can be made by loosening the four motor mounting bolts from the mounting plate.

To adjust belt tension:

1. Loosen the two motor mounting nuts as shown in Fig. 49. Some models may have a third mounting nut located on the opposite side of the fan motor mounting plate.

2. Slide motor mounting plate away from fan scroll for proper belt tension (

/2-in.deflectionwith8to10lbof

force) and tighten mounting nuts.

3. Adjust lock bolt and nut on mounting plate to secure motor in fixed position.

PRE-START-UP

FIRE, EXPLOSION, ELECTRICAL SHOCK HAZARD

Failur e to follow this warning could result in personal injury, death and/or propert y damage:

1. Follow recogniz ed s a fety practices and wear protec tive goggles when checking or servi cing a refri gerant system.

2. Do not ope rate the compressor or provide any electric power to the unit unless the compressor terminal cover is in place and secured.

3. Do not remove the compressor t ermina l cover until all electrical sources are disconnect ed and t agged with lockout tags.

4. Relie ve all pressure from the s ystem before touching or disturbing anything inside the termi nal box if a refrigerant leak is suspec ted around the compressor terminals. Use accepted methods to rec over the refrigerant.

5. Never attempt to repair a soldered connection while the refrigerant system is under press ur e.

6. Do not use a torch to remove any component . The system contains oil and refriger ant under pressure. To remove a component, wear protecti ve goggles and proceed as follows:

a. Shut off electrical power to the unit and tag

b. Recover refrigerant to relieve all pressure

c. Cut component connection tubing with a

d. Carefully unsweat the remaining tubing

Proceed as follows to inspect and prepare the unit for initial start-up:

1. Remove all access panels.

2. Read and follow instructions on all WARNING, CAUTION, and INFORMATION labels attached to, or shipped with, unit.

3. Make the following inspections:

a. Inspect for shipping and handling damages such as

broken lines, loose parts, or disconnected wires, etc.

b. Inspect for oil at all refrigerant tubing connections and on

unit base. Detecting oil generally indicates a refrigerant leak. Leak-test all refrigerant tubing connections using electronic leak detector, halide torch, or liquid-soap solution.

c. Inspect all field-wiring and factory-wiring connections.

Be sure that connections arecompleted and tight. Be sure that wires are not in contact with refrigerant tubing or sharp edges.

d. Inspect coil fins. If damaged during shipping and

handling, carefully straighten fins with a fin comb.

4. Verify the following conditions:

a. Make sure that condenser-fan blade are correctly

positioned in fan orifice. See Condenser-Fan Adjustment section for more details.

d. Make sure that all tools and miscellaneous loose parts

have been removed.

START-UP

Step 1 —Unit Preparation

Make sure that the unit has been installed in accordance with installation instructions and applicable codes.

Step 2 —Gas Piping

Check gas piping for leaks.

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could cause personal injury or death.

Disc onnect gas piping from unit when leak testing at pressure greater than psig will cause gas valve damage resulting in hazardous condition. If gas va lve is subjecte d to pressure greater than

/2psig, it must be replaced before use. When pressure testing field- supplied gas piping at pressures of or less , a unit connecte d to such piping must be isolated by manual l y closing the gas valve.

Step 3 —Return--Air Filters

Make sure the correct filters are installed in the unit (See Table 1 or 2). Do not operate the unit without return-air filters.

Step 4 —Outdoor--Air Inlet Screens

Outdoor-air inlet screen(s) must be in place before operating the unit.

Step 5 —Compressor Mounting

Compressors are internally spring mounted. Do not loosen or remove the compressor holddown bolts.

Step 6 —Internal Wiring

Check all electrical connections in unit control boxes; tighten them as required.

Step 7 —Refrigerant Service Ports

Each unit system has 4 Schrader--type service ports: one on the suction line, one on the liquid line, and 2 on the compressor discharge line. Be sure that caps on the ports are tight. Two additional Schrader valves are located under the high--pressure and low--pressure switches, respectively.

Step 8 —High Flow Refrigerant Valves

Two high flow valves are located on the hot gas tube coming out of the compressor and the suction tube going into the compressor. Large black plastic caps identify these valves. These valves have O--rings inside which screw the cap onto a brass body to prevent leaks. No field access to these valves is available at this time. Ensure the plastic caps remain on the valves and are tight or the possibility of refrigerant leakage could occur.

Step 9 —Compressor Rotation

On 3-phase units be certain that the compressor is rotating in the proper direction. To determine whether or not compressor is rotating in the proper direction:

1. Connect the service gauges to suction and discharge pressure fittings.

2. Energize the compressor.

3. The suction pressure should drop and the discharge pressure should rise, as is normal on any start-up.

If the suction pressure does not drop and the discharge pressure does not rise to normal levels:

1. Note that the indoor fan (006 and 007 three-phase units only) is probably also rotating in the wrong direction.

WARNING

/2psig. Pressures greater than1/

/2psig

48HE,HJ

Page 46

2. Turn off power to the unit and tag disconnect.

3. Reverse any two of the unit power leads.

4. Turn on power to the unit and energize the compressor.

The suction and discharge pressure levels should now move to their normal start-up levels.

NOTE: When the compressor is rotating in the wrong direction, the unit makes more noise and does not provide cooling.

Step 10 —Cooling

Set the space thermostat to the OFF position. Set the system selector switch at COOL position and the fan switch at AUTO position. Adjust the thermostat to a setting below room temperature. The compressor starts when contactor closes.

Check the unit charge. Refer to Refrigerant Charge section. Reset the thermostat at a position above room temperature. The

compressor will shut off. Evaporator fan will shut off after a 30--second delay.

To Shut Off Unit -- Set the system selector switch at OFF position. Resetting the thermostat at a position above room temperature shuts off the unit temporarily until the space

48HE,HJ

temperature exceeds the thermostat setting. Units are equipped with a Cycle-LOC protection device. The unit shuts down on any safety trip and remains off; an indicator light on the thermostat comes on. Check the reason for the safety trip.

Step 11 —Main Burners

Main burners are factory set and should require no adjustment. TO CHECK ignition of main burners and heating controls, move

thermostat set point above room temperature and verify that the burners light and evaporator fan is energized. Check heating effect, then lower the thermostat setting below the room temperature and verify that the burners and evaporator fan turn off.

Refer to Tables 37 and 38 for the correct orifice to use at high altitudes.

Step 12 —Heating

1. Purge gas supply line of air by opening union ahead of the gas valve. If gas odor is detected, tighten union and wait 5 minutes before proceeding.

2. Turn on electrical supply and manual gas valve.

3. Set system switch selector at HEAT position and fan switch at AUTO or ON position. Set heating temperature lever above room temperature.

4. The induced-draft motor will start.

5. After a call for heating, the main burners should light within 5 seconds. If the burner does not light, then there is a 22-second delay before another 5-second try. If the burner still does not light, the time delay is repeated. If the burner does not light within 15 minutes, there is a lockout. To reset the control, break the 24 v power to W1.

6. The evaporator-fan motor will turn on 45 seconds after burner ignition.

7. The evaporator-fan motor will turn off in 45 seconds after the thermostat temperature is satisfied.

8. Adjust airflow to obtain a temperature rise within the range specified on the unit nameplate.

NOTE: The default value for the evaporator-fan motor on/off delay is 45 seconds. The Integrated Gas Unit Controller (IGC) modifies this value when abnormal limit switch cycles occur. Based upon unit operating conditions, the on delay can be reduced to 0 seconds and the off delay can be extended to 180 seconds. When one flash of the LED (light-emitting diode) is observed, the evaporator-fan on/off delay has been modified.

If the limit switch trips at the start of the heating cycle during the evaporator on delay, the time period of the on delay for the next cycle will be 5 seconds less than the time at which the switch tripped. (Example: If the limit switch trips at 30 seconds, the evaporator-fan on delay for the next cycle will occur at 25 seconds.) To prevent short-cycling, a 5-second reduction will only occur if a minimum of 10 minutes has elapsed since the last call for heating.

The evaporator-fan off delay can also be modified. Once the call for heating has ended, there is a 10-minute period during which the modification can occur. If the limit switch trips during this period, the evaporator-fan off delay will increase by 15 seconds.

Page 47

A maximum of 9 trips can occur, extending the evaporator-fan off delay to 180 seconds.

To restore the original default value, reset the power to the unit. To Shut Off Unit —Set system selector switch at off position.

Resetting heating selector lever below room temperature will temporarily shut unit off until space temperature falls below thermostat setting.

Step 13 —Safety Relief

A soft solder joint at the suction line fitting provides pressure relief under abnormal temperature and pressure conditions.

Step 14 —Ventilation (Continuous Fan)

Set fan and system selector switches at ON and OFF positions, respectively. Evaporator fan operates continuously to provide constant air circulation. When the evaporator--fan selector switch is turned to the OFF position, there is a 30--second delay before the fan turns off.

Step 15 —Operating Sequence

cooling -- units without

When thermostat calls for cooling, terminals G and Y1 are energized. The indoor-fan contactor (IFC), reversing valve solenoid (RVS) and compressor contactor are energized and indoor-fan motor, compressor, and outdoor fan starts. The outdoor fan motor runs continuously while unit is cooling.

heating -- units without

When the thermostat calls for heating, terminal W1 is energized. To prevent thermostat short--cycling, the unit is locked into the Heating mode for at least 1 minute when W1 is energized. The induced--draft motor is energized and the burner ignition sequence begins. The indoor (evaporator) fan motor (IFM) is energized 45 seconds after a flame is ignited. On units equipped for two stages of heat, when additional heat is needed, W2 is energized and the high--fire solenoid on the main gas valve (MGV) is energized. When the thermostat is satisfied and W1 is deenergized, the IFM stops after a 45--second time--off delay.

Cooling -- units with economi$er

When free cooling is not available, the compressors will be controlled by the zone thermostat. When free cooling is available, the outdoor-air damper is modulated by the EconoMi$er IV control to provide a 50_ to 55_F supply-air temperature into the zone. As the supply-air temperature fluctuates above 55_ or below 50_F, the dampers will be modulated (open or close) to bring the supply-air temperature back within the set point limits.

Integrated EconoMi$er IV operation on single-stage units requires a 2-stage thermostat (Y1 and Y2).

For EconoMi$er IV operation, there must be a thermostat call for the fan (G). This will move the damper to its minimum position during the occupied mode.

If the increase in cooling capacity causes the supply--air temperature to drop below 45_F, then the outdoor--air damper position will be fully closed. If the supply --air temperature continues to fall, the outdoor--air damper will close. Control returns to normal once the supply--air temperature rises above 48_F.

If optional power exhaust is installed, as the outdoor--air damper opens and closes, the power exhaust fans will be energized and deenergized.

If field--installed accessory CO EconoMi$er IV control, a demand controlled ventilation strategy will begin to operate. As the CO above the CO will be increased proportionally. As the CO because of the increase in fresh air, the outdoor--air damper will be proportionally closed. Damper position will follow the higher demand condition from DCV mode or free cooling mode.

Damper movement from full closed to full open (or vice versa) will take between 1--1/2 and 2--1/2 minutes.

If free cooling can be used as determined from the appropriate changeover command (switch, dry bulb, enthalpy curve, differential dry bulb, or differential enthalpy), a call for cooling (Y1 closes at the thermostat) will cause the control to modulate the dampers open to maintain the supply air temperature set point at 50_ to 55_ F.

As the supply air temperature drops below the set point range of 50_ to 55_ F, the control will modulate the outdoor--air dampers closed to maintain the proper supply--air temperature.

heating -- units with economi$er

When the room temperature calls for heat, the heating controls are energized as described in the Heating, Units Without Economizer section. When the thermostat is satisfied, the economizer damper moves to the minimum position.

cooling -- units with economi$er2, premierlink AND A THERMOSTA

When free cooling is not available, the compressors will be controlled by the PremierLink control in response to the Y1 and Y2 inputs from the thermostat.

The PremierLink control will use the following information to determine if free cooling is available:

t CONTROL

S Indoor fan has been on for at least 30 seconds. S The SPT, SAT, and OAT inputs must have valid

readings.

S OAT must be less than 75_F. S OAT must be less than SPT. S Enthalpy must be LOW (may be jumpered if an

enthalpy sensor not available).

S Economizer position is NOT forced.

Pre-cooling occurs when there is no call from the thermostat except G. Pre-cooling is defined as the economizer modulates to provide 70_F supply air.

When free cooling is available the PremierLink control will control the compressors and economizer to provide a supply-air temperature determined to meet the Y1 and Y2 calls from the thermostat using the following three routines. The three control routines are based on OAT.

The 3 routines are based on OAT where: SASP = Supply Air Set Point DXCTLO = Direct Expansion Cooling Lockout Set Point PID = Proportional Integral Routine 1 (OAT < DXCTLO)

S Y1 energized – economizer maintains a SASP =

(SATLO1 + 3).

S Y2 energized – economizer maintains a SASP =

Routine 2 (DXCTLO<OAT<68_F)

S If only Y1 energized, the economizer maintains a

SASP = (SATLO1 + 3).

S If SAT > SASP + 5 and economizer position > 80%,

economizer will go to minimum position for 3 minutes or until SAT > 68_F.

S First stage of mechanical cooling will be energized. S Integrator resets. S Economizer opens again and controls to current SASP

HEATING -- UNITS WITH ECONOMI$ER2, LINK CONTROL AND A THERMOSTA

When the thermostat calls for heating, terminal W1 is energized. The PremierLink control will move the economizer damper to the minimum position if there is a call for G and closed if there is a call for W1 without G. In order to prevent thermostat from short cycling, the unit is locked into the heating mode for at least 10 minutes when W1 is energized. The induced--draft motor is then energized and the burner ignition sequence begins.

On units equipped for two stages of heat, when additional heat is needed, W2 is energized and the high--fire solenoid on the main gas valve (MGV) is energized. When the thermostat is satisfied and W1 is deenergized, the IFM stops after a 45--second time--off delay unless G is still maintained.

When free cooling is not available, the compressors will be controlled by the PremierLink controller using a PID Error reduction calculation as indicated by Fig 51.

The PremierLink controller will use the following information to determine if free cooling is available:

Fig. 52 --- Economizer Temperature

Control Example

When free cooling is available, the outdoor-air damper is positioned through the use of a Proportional Integral (PID) control process to provide a calculated supply-air temperature into the zone. The supply air will maintain the space temperature between the heating and cooling set points as indicated in Fig. 52.

The PremierLink control will integrate the compressor stages with the economizer based on similar logic as the three routines listed in the previous section. The SASP will float up and down based on the error reduction calculations that compare space temperature and space set point.

When outside-air temperature conditions require the economizer to close for a compressor stage-up sequence, the economizer control integrator is reset to zero after the stage-up sequence is completed. This prevents the supply-air temperature from dropping too quickly and creating a freeze condition that would make the compressor turn off prematurely.

The high space set point is used for DX (direct expansion) cooling control, while the economizer space set point is a calculated value between the heating and cooling set points. The economizer set point will always be at least one degree below the cooling set point, allowing for a smooth transition from mechanical cooling with economizer assist, back to economizer cooling as the cooling set point is achieved. The compressors may be used for initial cooling then the PremierLink controller will modulate the economizer using an error reduction calculation to hold the space temperature between the heating and cooling set points. (See Fig. 52.)

The controller uses the following conditions to determine economizer cooling:

S Enthalpy is Low S SA T reading is available S OA T reading is available

Page 49

S SPT reading is available S OAT ± SPT S Economizer Position is NOT forced

If any of the above conditions are not met, the economizer submaster reference (ECSR) is set to maximum limit and the damper moves to minimum position. The operating sequence is complete. The ECSR is recalculated every 30 seconds.

If an optional power exhaust is installed, as the outdoor-air damper opens and closes, the power exhaust fans will be energized and deenergized.

If field-installed accessory CO PremierLink control, a PID-controlled demand ventilation strategy will begin to operate. As the CO increases above the CO damper will be increased proportionally. As the CO decreases because of the increase in fresh air, the outdoor-air damper will be proportionally closed.

HEATING -- UNIT WITH ECONOMI$ER2, LINK CONTROL AND A ROOM

S Indoor fan has been on for at least 30 seconds. S COOL mode is not active. S OCCUPIED, TEMP. COMPENSATED START or

HEAT mode is active.

S SA T reading is available. S Fire shutdown mode is not active.

If all of the above conditions are met, the number of heat stages is calculated; otherwise the required number of heat stages will be set to 0.

If the PremierLink controller determines that heat stages are required, the economizer damper will be moved to minimum position if occupied and closed if unoccupied.

Staging should be as follows: If Heating PID STAGES=2

S HEAT STAGES=1 (50% capacity) will energize HS1 S HEAT STAGES=2 (100% capacity) will energize HS2

If Heating PID STAGES=3 and AUXOUT = HS3

S HEAT STAGES=1 (33% capacity) will energize HS1 S HEAT STAGES=2 (66% capacity) will energize HS2 S HEAT STAGES=3 (100% capacity) will energize HS3

In order to prevent short cycling, the unit is locked into the Heating mode for at least 10 minutes when HS1 is deenergized. When HS1 is energized the induced-draft motor is then energized and the burner ignition sequence begins. On units equipped for two stages of heat, when additional heat is needed, HS2 is energized and the high-fire solenoid on the main gas valve (MGV) is energized. When the space condition is satisfied and HS1 is deenergized the IFM stops after a 45-second time-off delay unless in the occupied mode. The fan will run continuously in the occupied mode as required by national energy and fresh air standards.

UNITS WITH HUMIDI-MIZER DEHUMIDIFICATION

Normal Design Operation

When the rooftop operates under the normal sequence of operation, the compressors will cycle to maintain indoor conditions. (See Fig. 53.)

The Humidi-MiZer adaptive dehumidification system includes a factory-installed Motormaster low ambient control to keep the

SYSTEM

 ADAPTIVE

head and suction pressure high, allowing normal design cooling mode operation down to 0 F.

Subcooling Mode

When subcooling mode is initiated, this will energize (close) the liquid line solenoid valve (LLSV) forcing the hot liquid refrigerant to enter into the subcooling coil. (See Fig. 54.)

As the hot liquid refrigerant passes through the subcooling/ reheat dehumidification coil, it is exposed to the cold supply airflow coming through the evaporator coil. The liquid is further subcooled to a temperature approaching the evaporator leaving-air temperature. The liquid then enters a thermostatic expansion valve (TXV) where the liquid drops to a lower pressure. The TXV does not have a pressure drop great enough to change the liquid to a 2-phase fluid, so the liquid then enters the Acutrol device at the evaporator coil.

The liquid enters the evaporator coil at a temperature lower than in standard cooling operation. This lower temperature increases the latent capacity of the rooftop unit. The refrigerant passes through the evaporator and is turned into a vapor. The air passing over the evaporator coil will become colder than during normal operation. However, as this same air passes over the subcooling coil, it will be slightly warmed, partially reheating the air.

Subcooling mode operates only when the outside air temperature is warmer than 40_F. A factory-installed temperature switch located in the condenser section will lock out subcooling mode when the outside temperature is cooler than 40_F.

The scroll compressors are equipped with crankcase heaters to provide protection for the compressors due to the additional refrigerant charge required by the subcooling/reheat coil.

When in subcooling mode, there is a slight decrease in system total gross capacity (5% less), a lower gross sensible capacity (20% less), and a greatly increased latent capacity (up to 40% more).

Reheat Mode Operation

Hot Gas Reheat Mode

When the humidity levels in the space require humidity control, a hot gas solenoid valve (specific to hot gas reheat mode only) will open to bypass a portion of hot gas refrigerant around the condenser coil. (See Fig. 55.)

This hot gas will mix with liquid refrigerant leaving the condenser coil and flow to the subcooling/reheat dehumidification coil. Now the conditioned air coming off the evaporator will be cooled and dehumidified, but will be warmed to neutral conditions (72_Fto75_F) by the subcooling/reheat dehumidification coil.

The net effect of the rooftop when in hot gas reheat mode is to provide nearly all latent capacity removal from the space when sensible loads diminish (when outdoor temperature conditions are moderate). When in hot gas reheat mode, the unit will operate to provide mostly latent capacity and extremely low sensible heat ratio capability.

Similar to the subcooling mode of operation, hot gas reheat mode operates only when the outside air temperature is warmer than 40_F. Below this temperature, a factory installed outside air temperature switch will lockout this mode of operation.

See Table 39 for the Humidi-Mizer adaptive dehumidification system sequence of operation.

Using Cooling Charging Charts, Fig. 60--63, vary refrigerant until the conditions of the charts are met. Note the charging charts are different from type normally used. Charts are based on charging the units to the correct superheat for the various operating conditions. Accurate pressure gage and temperature sensing device are required. Connect the pressure gauge to the service port on the suction line. Mount the temperature sensing device on the suction line and insulate it so that outdoor ambient temperature does not affect the reading. Indoor-air cfm must be within the normal operating range of the unit.
