For horizontal applications, field-

Secure all

supplied 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 shall not exceed –.30 in. wg with EconoMi$er, or –.35 in. wg with Durablade Economizer, or –.45 in. wg without economizer.

These units are designed for a m inimum continuous returnair temperature of 50 F (dry bulb), or an intermittent operation down to 45 F (dry bulb) (in heating mode), such as when used with a night set-back thermostat.

Step 3 — Install External Trap for Condensate Drain —

located on the bottom and side of the unit. Unit discharge connections do not determine the use of drain connections; either drain connection can be used with ve rtical or horiz ontal applications.

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

To use the bottom drai n connection for a roof curb installation, relocate the factory-installed plug (Red) from the bottom connection to the side connection. 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 at least 4-in. deep and protect against fr eezeup. 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 (

Fig. 4 — Internal Trap Condensate Drain

POS ITION ING — Maintain cleara nce around and above unit to provide minimum distance from combustible materials, proper airflow, and service access. See Fig. 6. A properly positioned unit will have the following clearances between unit and roof curb:

/4-in. clearance between roof curb and ba se rails on each side and duct end of unit; 1/4-in. clearance between roof curb and condenser coil end of unit. (See Fig. 2, section C-C.)

Do not install unit in an indoor location. Do not locate unit air inlets within 10 ft of exhaust vents or other sources of contaminated air or as local codes require.

Be sure that unit is installed so that snow will not block the

combustion intake or flue outlet.

Unit may be installed directly on wood flooring or on Class

A, B, or C roof-covering material when roof curb is used.

Although unit is weatherproof, guard against water from

higher level runoff and overhangs.

Flue vent discharge must have a minimum horizontal clearance of 4 ft from electric and gas meters, gas regulators, and gas relief equipment.

Minimum distance between unit and other electrically live parts is 48 inches.

Flue gas can deteriorate building materials. Orient unit such that flue gas will not affect building materials.

Adequate combustion-air space must be provided for proper operation of this equipment. Be sure that installation complies with all local codes and Section 5.3, Air for Combustion and Ventilation, NFGC (National Fuel Gas Code), and ANSI (American National Standards Institute) Z223.1, and NFPA (National Fire Protection Association) 54 TIA-54-84-1. In Canada, installation must be in accordance with the CAN1- B149 installation codes for gas burning appliances.

After unit is in position, remove rigging skids and shipping materials.

Step 5 — Install Flue Hood —

Flue hood is shipped screwed to the burner compartment access panel. Remove from shipping location and using screws provided, install flue hood and screen in location shown in Fig. 7.

For units size 004-006 being installed in California Air Quality Management Districts, which require NOx emissions of 40 nanograms/joule or less, a field-installed low NOx kit must be used.

Step 6 — Install Gas Piping —

Unit is equipped for use with type of gas shown on nameplate. Refer to local building codes, or in the absence of local codes, to ANSI Z223.1 entitled National Fuel Gas Code. In Canada, installation must be in accordance with the CAN1.B149.1 and CAN1.B149.2 installation codes for gas burning appliances.

For natural gas applications, gas pressure at unit gas

connection must not be less than 4 in. wg or greater than

13.0 in. wg while unit is operating. On 48TJ005,006,007 high heat units, the gas pressure at unit gas connection must not be less than 5 in. wg or greater t han 13 in. wg while the unit is operating. For propane applications, the gas pressure must not be less than 5 in. wg or greater than 13 in. wg at the unit connection.

Size gas sully piping for 0.5 in. wg maximum pressure drop. Do not use supply pipe small than unit gas connection. Support gas piping as shown in the table in Fig. 8. For example, a

/4-in. gas pipe must have one field-fabricated support beam every 8 ft. Therefore, an 18-ft long gas pipe would have a minimum of 2 support beams, a 48-ft long pipe would have a minimum of 6 support beams.

See Fig. 8 for typical pipe guide and locations of external

manual main shutoff valve.

Voltage to compressor terminals during operation must be within voltage range indicated on unit nameplate (see Table 2). On 3-phase units, voltages between phases must be balanced within 2% and the current within 10%. Use the formula shown in the legend for Table 2, Note 2 to determine 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.

FIELD CONTR OL WIRING — Install a Carrier-approved accessory thermostat assembly according to installation instructions included with the accessory. Locate thermostat assembly on a solid wall in the conditioned space to sense average temperature in accordance with thermostat installation instructions. Connect thermostat wires to terminal board.

Route thermostat cable or equivalent single leads of colored wire from subbase terminals through connector on unit to lowvoltage connections (shown in Fig. 12).

Control Set Up — If a CO2 sensor is not being used,

proceed to the next section. If a CO

sensor is being used, per-

form the following:

1. Determine the value at which you want the minimum position of the dampers to begin opening to allow a greater amount of outdoor air to enter. The range is 800 to 1,400 ppm.

2. Locate the CO

SP (PPM) potentiometer and adjust to the

desired set point. See Fig. 38.

Mechanical Cooling Lockout

— Determine the outdoor-air temperature at which you want the mechanical cooling (compressors) to be disabled. Locate the mechanical cooling lockout (MECH CLG LOCKOUT) potentiometer. To disable this feature, turn the potentiometer counterclockwise (CCW) to the OFF position. Otherwise, set the value between 10 and 60 F. Mechanical cooling will not operate when the outdoor air temperature is below this value. See Fig. 38.

Dry Bulb Cha ngeover Set Up

— Determine the dry bulb changeover set point from Table 3. The settings are A, B, C and D. Locate the ECON SP potentiometer and set the dry bulb changeover set point. See Fig. 38. When the OAT is above this set point, the damper is limited to minimum position setting.

Ventilation Air (Minimum Position Set up)

— If ventilation air is not required, proceed to Step 5. If ventilation air is required, perform the following:

1. The indoor fan must be on to set the ventilation air. Either put the thermostat in the continuous fan mode or jump er the R and G terminals at the rooftop unit connection board.

2. Locate the minimum position (MIN PO S) potentiometer. Turn the potentiometer full CCW to fully close the outdoor air dampers. Turn the potentiometer gradually clockwise (CW) to the desired position. See Fig. 38.

3. Replace the filter access panel. See Fig. 26. Ensure the filter access panel slides along the tracks and is securely engaged.

4. Calculate the minimum airflow across the EconoMi$er. a. Calculate % of outside air using the following

formula. % Outdoor air through EconoMi$er

% Outdoor air =

Mixture Temp – Return Air Temp Outdoor T emp – Return Air Temp

b. Divide total CFM by percentage outdoor air, this

gives outdoor air vol ume in CFM.

5. Turn on base unit power. NOTE: The EconoMi$er begins operation three min-

utes after power up.

Personal Injury Hazard.

Avoid possible injury by keep-

ing fingers away from damper blades.

Step 9 — Adjust Evaporator-Fan Speed —

Adjust evaporator-fan rpm to meet jobsite conditions. Table 5 shows fan rpm at motor pulley settings. Table 6 shows motor performance. See Table 7 for Accessory/FIOP Static Pressure. Refer to Tables 8-29 to determine fan speed settings.

DIRECT-DRI VE MOTORS — The evaporator-fan motor factory speed setting is shown on label diagram affixed to base unit. If other than factory setting is desired, refer to label diagram for motor reconnection. See Fig. 40 for direct drive motor location.

BELT-DRIVE MOTORS — Fan motor pulleys are factory set for speed shown in Table 1. See Fig. 41 for belt drive location.

NOTE: Before adjusting fan speed, make sure the new fan speed will provide an air temperature rise range as shown in T able 1.

T o change fan speed:

1. Shut off unit power supply and tag disconnect.

2. Loosen belt by loosening fan motor mounting nuts. See Fig. 41.

3. Loosen movable pulley flange setscrew (see Fig. 42).

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.

START-UP

Unit Preparation —

stalled in accordance with these installation instructions and applicable codes.

Return-Air Filters —

stalled in filter tracks. See Table 1. Do not operate unit without return-air filters.

Compressor Mounting —

spring mounted. Do not loosen or remove compressor holddown bolts.

Internal Wiring —

unit control boxes. Tighten as required. Ensure electrical wires do not come in contact with refrigerant tubing or sharp edges.

Refrigerant Service Ports —

service ports, remove refrigerant service port access panel. See Fig. 43. Each unit system has 4 Schrader-type service gage ports: one on the suction line, one on the liquid line, and two on the compressor discharge line. Be sure that caps on the ports are tight. When a controls upgrade package is used, one Schrader-type valve is located under both the high-pressure switch and the low-pressure switch.

High Flow Valves —

and suction tubes are High Flow Valves. Large black plastic caps distinguish these valves with o-rings located inside the caps. These valves can not be acce ssed f or servic e in t he fiel d. Ensure the plastic caps are in place and tight or the possibility of refrigerant leakage could occur.

Make sure that unit has been in-

2. Turn off power to the unit and install lockout tag.

3. Reverse any two of the unit power leads.

4. Reapply power to unit and recheck pressures. The suction and discharge pressure levels should now move

to their normal start-up levels. NOTE: When the compressor is rotating in the wrong direc-

tion, the unit makes an elevated level of noise and does not provide cooling.

Cooling —

Set space thermostat of OF F position. To start unit, turn on main power supply. Set system selector switch at COOL position and fan switch at AUTO. position. Adjust thermostat to a setting below room temperature. Compressor starts on closure of contactor.

Check unit charge. Refer to Service, Refrigerant Charge section, page 41. Allow unit to operate a minimum of 10 mi nutes before checking charge.

Reset thermostat at a position above room temperature. Compressor will shut off. Evaporator fan will shut off after 30-second delay.

TO SHUT OFF UNIT — Set s y stem selector switch at OFF position. Resetting thermostat at a position above room temperature shuts unit off temporarily until space temperature exceeds thermostat setting.

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. After ensuring that the unit continues to heat the building, lower the thermostat setting below room temperature and verify that the burners and evaporator fan turn off. (Fan will turn off only if fan selector switch is in the AUTO. position and after a 45-second delay has elapsed.)

Refer to Table 30 for the correct orifice to use at high altitudes.

Fig. 43 — Service Panel Location

Compressor Rotation —

On 3-phase units with scroll compressors, it is important to be certain compressor is rotating in the proper direction. To determine whether or not compressor is rotating in the proper direction:

1. Connect service gages to suction and discharge pressure fittings.

2. Energize the unit.

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 pres-

sure does not rise to normal levels:

1. Note that the evaporat or fan is probably also rotating in the wrong direction.

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 i nduced-draf t motor w ill star t.

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.

ADJU ST G AS I NPUT — The gas input to the unit is determined by measuring the gas flow at the meter or by measuring the manifold pressure. Measuring the gas flow at the meter is recommended for natural gas units. The manifold pressure must be measured to determine the input of propane gas units.

Measure Gas Flow (Natural Gas Units) to the gas flow can be made by changing the manifold pressure. The manifold pressure must be maintained between 3.4 and

3.6 in. wg. If larger adjustments are required, change main burner orifices following the recommendations of national and local codes. Unit must be operating with both W1 and W2 energized (high-fire).

NOTE: All other appliances that use the same meter must be turned off when gas flow is measured at the meter.

Proceed as follows:

1. Turn off gas supply to unit. Turn off electric supply to unit and install lockout tag.

2. Remove pipe plug on manifold (see Fig. 44) then connect manometer at this point. Turn on gas to unit.

3. Turn on electrical power.

4. Energize W1, and/or W2 at thermostat. Ensure gas valve, if 2-stage style, is in “High Fire.”

Observe manifold pressure and proceed as follows to adjust

gas input:

1. Remove cover screw over regulator adjustment screw on gas valve.

2. Turn regulator adjustment screw clockwise to increase gas input, or turn regulator adjustment screw counterclockwise to decrease input. Manifold pressure must be

3.5 in. wg while in high fire.

Unsafe operation of the unit may result i f manifold pressure is outside this range. Personal injury or unit damage may result.

3. Replace cover screw cap on gas valve.

4. Turn off gas supply to unit. Remove manometer from pressure tap and replace pipe plug on gas valve. Turn on gas to unit and check for leaks.

Measure Manifold Pressure (Propane Units) burner orifices on a propane gas unit are sized for the unit rated input when the manifold pressure reading is 3.5 in. wg.

Ensure unit is operating in High-Fire operation mode (W1

and W2 energized) before adjusting manifold pressure.

Proceed as follows to adjust gas input on a propane gas unit:

1. Turn off gas to unit.

2. Remove pipe plug on manifold (see Fig. 44), then connect manometer at this point.

— Minor adjustment

— The main

3. Turn on gas to unit.

4. Remove cover screw over regulator adjustment screw on gas valve.

5. Adjust regulator adjustment screw to the correct manifold pressure, 3.5 in wg. Turn adjusting screw clockwise to increase manifold pressure, or turn adjusting screw counterclockwise to decrease manifold pressure.

6. Replace cover screw.

7. Turn off gas to unit. Remove manometer from pressure tap. Replace pipe plug on gas valve, then turn on gas to unit. Check for gas leaks.

8. The evaporator-fan m otor will turn on 45 seconds after the burners are ignited.

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

10. 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 operat ing 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 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 e lapsed 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. A maximum of 9 trips can occur, extending the evaporator-fan OFF delay to 180 seconds.

To restore the original defaul t value, reset the power t o the unit.

TO SHUT OFF UNIT — Set s y stem selector switch at OFF position. Resetting heating selector lever below room temperature will shut unit off until space temperature falls below thermostat setting.

Page 39

Safety Relief —

Schrader port provides pressure relief under abnormal temperature and pressure conditions (i.e., fire in building). Us e backup wrench when tightening flare cap.

High Flow Valves —

and suction tubes are High Flow Valves. Large black plastic caps distinguish these valves with O-rings located inside the caps. These valves cannot be accessed for servi ce in the field. Ensure the plastic caps are in place and tight or the possibility of refrigerant leakage could occur.

Ventilation (Continuous Fan) —

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

Operating Sequence

COOLING, UNITS WITHOUT ECONOMIZER — When thermostat calls for cooling, terminals G and Y1 are energized, and the indo or (evaporat or) fan mot or (IFM), c ompressor, and outdoor (conden ser ) fan m oto r (OFM start. The OFM runs continuously while the unit is in cooling. When the thermostat is satisfied, compressor contactor (C) is deenergized and the compressor and OFM shut off. After a 30-second delay, the IFM shuts off. If the thermostat fan selector s witch is the ON position, the evaporator motor will run continuously.

HEATING, UN ITS WI THOUT ECON OMIZ ER — When the thermost at calls for heating, ter minal W1 is en ergized. 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 i s satisfied a nd W1 is deenergized, the IFM stops after a 45-second time-off delay.

COOLING, UNITS WITH DURABLADE ECONOMIZER — When the outdoor-air temperature is above the outdoor-air thermostat (OAT) setting and the room thermostat calls for cooling, compressor contactor is energized to start compressor and the outdoor (condenser) fan motor (OFM). The indoor (evaporator) fan motor (IFM) is energized and the economizer damper moves to the minimum position. After the thermostat is satisfied, there is a 30-second delay before the evaporator fan turns off. The damper then moves to the fully closed position. When using continuous fan, the damper moves to the minimum position.

When the outdoor-air temperature is below the OAT setting and the thermostat calls for cooling, the economizer damper moves to the minimum position. If the supply-air temperature is above 57 F , the damper continues to open until it reaches the fully open position or until the supply-air temperature drops below 52 F .

When the supply-air temperature falls to between 57 F and 52 F, the damper w ill remai n at a n interm ediate open position. If the supply-air temperature falls below 52 F, the damper will modulate closed until it reaches the minimum position or until the supply-air temperature is above 52 F. When the thermostat is satisfied, the damper will move to the fully closed position when using AUTO. fan or to the minimum position when using a continuous fan.

If the outdoor air alone cannot satisfy the cooling require ments of the conditioned space, economizer cooling is integrated with mechanical cooling, providing two stages of cooling. Compressor and the condenser fan will be energized and the

position of the economizer damper will be determined by the supply-air temperature. When the second stage of cooling is satisfied, the compressor and OFM will be deenergized. The damper position will be determined by the supply-air temperature. When the first stage of cooling is satisfied, there is a 30-second delay before the evaporator fan shuts off. The damper then moves to the fully closed position. When using a continuous fan, the damper moves to the minimum position.

COOLING, UNITS WITH ECONOMI$ER — When the outdoor-air temperature (OA T) is above the ECON SP set point and the room thermostat calls for Stage 1 cooling (R to G + Y1), the indoor (evaporator) fan motor (IFM) is energized and the EconoMi$er damper modulates to minimum position. T he compressor contactor is energized to start the compressor and outdoor (condenser) fan motor (OFM). After the th ermostat is satisfied, the damper modulates to the fully closed position when the IF M i s dee ne r gi ze d.

When the OAT is below the ECON SP setting and the room thermostat calls for Stage 1 cooling (R to G + Y1), the EconoMi$er modulates to the minimum position when the IFM is energized. The EconoMi$er provides Stage 1 of cooling by modulating the return and outdoor air dampers to maintain a 55 F supply air set point. If the supply-air temperature (SAT) is greater than 57 F, the EconoMi$er modulates open, allowing a greater amount of outdoor air to enter the unit. If the SA T drops below 53 F, the outdoor air damper modulates closed to reduce the amount of outdoor air. When the SAT is between 53 and 57 F , the EconoMi$er maintains its position.

If outdoor air alone cannot satisfy the cooling requirements of the conditioned space, and the OAT is above the MECH CLG LOCKOUT set point, the EconoMi$er integrates free cooling with mechanical cooling. This is accomplished by the strategies below.

NOTE: Compressor has a 2-minute Minimum On, Minimum Off, and Interstage delay timer.

1. If Y1 is ene rgized, and the room therm ostat calls for Y 2 (2-stage thermostat), the compressor and OFM are energized. The EconoMi$er damper is maintained at its current position.

2. If Y1 is energized for more than 20 minutes, and Y2 is not energized (whether or not a 2-stage thermostat is used), the compressor and OFM are energized. The EconoMi$er damper is maintained at its current position.

3. If Y1 is energized, and the compressor is already energized (see Step 2) and the room thermostat calls for Y2, the compressor continues to operate.

4. If the compressor is energized and the thermostat is satisfied, the compressor, the OFM, and IFM are deenergized and the EconoMi$er modulates closed.

When the OAT is below the MECH CLG LOCKOUT set

point, the compressors remain off. HEATING, UNITS WITH E CON OMI $ER — When the ther-

mostat calls for heating, termina l 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 induceddraft motor is energized and the burner ignition sequence begins. The indoor (evaporator) fan motor (IFM) is energized 45 seconds after a flame is ignited and the damper moves to the minimum position. On units equipped for two stages of heat, when additional heat is needed, W2 is energized and t he highfire 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 . The economizer damper then moves to the fully closed position. When using continuous fan, the damper will remain in the minimum position.

2. Check diode D18. If diode is not functioning properly, replace control board.

3. Confirm that the economizer control board is grounded properly at

PL6-4 (brown wire) and at brown terminal of the economizer control board (brown wire). The economizer motor must also be grounded properly at the negative motor terminal (brown wire).

4. Verify SW1 and SW3 are working and wired properly (see unit label

diagram).

5. Check for 24 vac input at both PL6-1 (red wire) and PL6-3 (black wire). If 24 vac not present, check unit wiring (see unit label diagram). If 24 vac is found in both places, check for 24 vac at the yellow terminal of the economizer control board (yellow wire). If 24 vac power is not present, replace the economizer control board.

verify that there is a minimum of 18 vdc at the positive motor terminal. If the motor is not operating, replace the motor.

2. Check OAT or EC by setting above outdoor temperature or humidity

level. If the OAT or EC switches do not close, replace OAT or EC.

1. Perform the following tests when OAT or EC is closed, Y1 is called

for and damper is at minimum position. Confirm 24 vac on gray

terminal of the economizer control board (gray wire). If 24 vac is

not present, check wiring (see unit label diagram).

2. Verify that SW1 and SW3 are wired correctly and working properly

(see unit label diagram).

3. Check to ensure that 24 vac exists at PL6-2 (blue wire). If 24 vac is

not present, check wiring (see unit wiring label diagram).

4. Check 24 vac output at PL6-10 (white wire). If 24 vac is not

present, replace economizer control board.

2. Check diode D19. If diode is not functioning properly, replace control board.

1. After verifying that the wiring is correct, modulate the damper to the

minimum position. Remove the calls for G.

2. If the damper does not move, check for 24 vac at PL6-1 (red wire).

If 24 vac is not present, check wiring (see unit label diagram).

3. If damper still does not move, check for 24 vac at blue terminal of

economizer control board (blue wire). If 24 vac is not present, replace the economizer circuit board.

2. If supply-air temperature is less than 52 F, 24 vac should be found

at terminal T1 on the SAT (violet wire). If 24 vac not found, replace SAT.

that there is a minimum of 18 vdc at the positive motor terminal. If a minimum if 18 vdc is present and the motor is still not operating, replace the motor.

1. Check voltage potential across batteries. If lower than 14 vdc,

replace close-on-power-loss power supply (9-v alkaline batteries). It is recommended that you check this emergency power supply on a regular basis or whenever the filters are changed.

2. If the close-on-power-loss and economizer control board are

functioning properly, check for 14 vdc or higher at the blue terminal of the economizer control board (blue wire) when power is discon-

nected from unit. If 14 vdc is not present, replace the control board.
