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 servic e air-conditioning equipment.

Untrained personnel can perform basic maintenance functions of cleaning coils and filters and replacing filters. All other operations sh o uld be perfor me d by trai ne d se rvi ce personnel. When working on air-conditioning equipment, observe precautions in the literature, tags and labels attached to the unit, and other safety precautions that apply.

Follow all safety codes. Wear safety glasses and work gloves. Use quenching cloth for unbrazing operations. Have fire extinguishers available for all brazing opera tions.

WARNING: Disconnect gas piping from unit when leak testing at pressure greater than 1/2 psig. Pressures greater tha n resulting in hazardous condition. If gas valve is subjected to pressure greater than replaced before use. When pressure testing fieldsupplied gas piping at pressures of unit connected to such piping must be isolated by manually closing the gas valve.

WARNING: Before performing service or maintenance operations on unit, turn off main power switch to unit and install a lockout tag. Electrical shock could cause personal injury.

CAUTION: Ensure voltage listed on unit data plate agrees with electrical supply p r ov ided fo r t he unit .

Unit is ship ped in t he ve rti cal d uc t con figu rat ion . To convert t o horizontal configuration, remove screws from side duct opening covers and remove covers. Using the same screws, install covers on vertical duct openings with the insulation-side down. Seals around duct openings must be tight. See Fig. 2.

Confirm before installation of unit that voltage, amperage and circuit protection requirements listed on unit data plate agree with power supply provided.

I. STEP 1 — PROVIDE UNIT SUPPORT

A. Roof Curb

Assemble and install accessory roof curb in accordance with instructions shipped with curb. See Fig. 3. Install insulation, cant strips, roofing felt, and counter flashing as shown. Duct-

work must be attached to curb, not to the unit. The accessory thru-the-bottom power and gas connection package must be installed before the unit is set on the roof curb. If field-

installed (thru-the-roof curb) gas connections are desired, use factory-supplied to mount the thru-the-roof curb connection to the roof curb. Gas connections and power connections to the unit must be field installed after the unit is installed on the roo f curb.

If electric and control wiring 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.

IMPORTANT: The gasketing of the unit to the roof curb is critical for a watertight seal. Install gasket supplied with the roof curb as shown in Fig. 3. Improperly applied gasket can result in air leaks and poor unit performance.

Curb should be level. Unit leveling tolerances are shown in Fig. 4. This is necessary for unit drain to function properly. Refer to Accessory Roof Curb Installation Instructions for additional information as required.

B. Slab Mount (Horizontal Units Only)

Provide a level concrete slab tha t extends a minimum of 6 in. beyond unit cabi ne t. I nsta ll a grav el apr on in f ron t of con dens er coil air inlet to prevent grass and foliage from obstructing airflow.

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

C. Alternate Unit Support

A non-combustible sleepe r rail can be used in the unit curb 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.

II. STEP 2 — FIELD FABRICATE DUCTWORK

Secure all ducts to roof curb and building s tructure on verti cal ducted units. Do not connect ductwork to unit. For h or izontal applications, fiel d-supplie d flanges sh ould b e attach ed to horizontal duct openings and all ductwork should be secured to the flanges. Insulate and weatherproof all external ductwork, joints , and roo f openings with counter flashing and mastic in accordance with applicable codes.

Ducts passing through a n unc ondit i one d spa ce 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) should not exceed 0.35 in. wg with economizer or 0.45 in. wg without economizer.

These units are designed for a minimum continuous heating return-air temperature of 50 F (dry bulb), or an intermittent operation down to 45 F (dry bulb), such as when used with a night set-back 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.

III. STEP 3 — INSTALL EXTERNAL TRAP FOR CONDENSATE DRAIN

The unit’s

/4-in. condensate drain connections are 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 vertical or horizontal 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 drain connection for a roof curb installation, relocate the factory-i nstalle d plug (Re d) from t he bott om connection to the side connection. The center dr ain plug l ooks like a star connection, however it can be removed with a

/2-in. socket drive. See Fig. 5A. 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 freeze-up. If drain line is installed downstream from the external trap, pitch the line away fr om the unit at 1 in. per 10 ft of r un. Do not use a pipe size smaller than the unit connection (

/4 in.). See Fig. 5B.

IV. STEP 4 — RIG AND PLACE UNIT

Inspect unit for transportation damage. 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. Rollers may be used to move unit across a roof. Level by using unit frame as a ref erence. See Table 1 and Fi g. 6 for additional information.

Lifting holes are provided in base rails as shown in Fig. 1A and 1B. Refer to rigging instructions on unit.

CAUTION: All panels must be in place when rigging. Unit is not designed for handling by a fork truck. Damage to unit may result.

A. Positioning

Maintain cleara nce around and abov e unit to provide mini mum distance from combustible materials, proper airflow, and service access. See Fi g. 1A and 1B. A properly positioned unit will have the fol lo wing c l ea ranc es be twe en uni t and r o of

curb:

/4-in. clearance between roof curb and base rails on each side and duct end of unit; 1/4-in. clearance between roof curb and condenser coil end of unit . (See Fig. 3, section C-C.)

Do not install unit in an indoor location. Do not locate unit air inlets near exhaust vents or other sources of contaminated air.

Be sure that unit is installed such 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 . Orie nt unit suc h 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 Protectio n As so ci atio n) 5 4 TI A -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.

V. STEP 5 — INSTALL FLUE HOOD

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

VI. STEP 6 — INSTALL GAS PIPING

Unit is equipped for use wi th 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 oper atin g. On 580F04 8,0 60,072 high heat units, the gas pressure at unit gas connection must not be less than 5 in. wg or greater than 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 supply piping for 0.5 in. wg maximum pressure drop. Do not use supply pipe smaller than unit gas connection. Support gas pipi ng as shown in the ta ble 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.

CAUTION: When connecting the gas line to the unit gas valve, the installer MUST use a backup wrench to prevent valve damage.

/4-in. male terminal on the primary side of the

transformer. Refer to unit label diagram for additional information.

Pigtails are provided for fie ld wire connectio ns. Use factorysupplied splices or UL (Underwriters’ Laboratories) approved copper/aluminum connector.

When installing units, provide a disconnect per the NEC. All field wiring must comply with NEC and local require-

ments. Install field wiring as foll ows:

1. Install conduit through side panel openings. Install conduit between disconnect and control box.

2. Install power lines to terminal connections as shown in Fig. 9.

Voltage to compressor terminals during operation must be within voltage range indicated on unit nameplate (see Tables 2A and 2B). 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 Tables 2A and 2B, Note 2 to determine the percent of voltage imbalance. Operation on impr op er lin e volta ge or excess ive phase imbalance constitutes abuse and may cause damage to electrical components. Such operation would invalidate any applicable Bryant warranty.

B. Field Control Wiring

Install a Bryant-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 low-voltage connections (shown in Fig. 10).

NOTE: For wire runs up 50 ft, use no. 18 AWG (American Wire Gage) insulated wire (35 C minimum). For 50 to 75 ft, use no. 16 AWG insulated wire (35 C minimum). For over

Maximum deviation is 7 v. Determine percent of voltage imbalance.

% Voltage Imbalance = 100 x

This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%. IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric

utility company immediately.

3. For units with power exhaust: If a single power source is to be used, size wire to include power exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered through the unit (must be in accordance with NEC and/or local codes). Determine the new MCA including the power exhaust using the following formula:

MCA New = MCA unit only + MCA of Power Exhaust For example, using a 580F060 unit with MCA = 28.9 and MOCP = 35, with

CRPWREXH030A01 power exhaust. MCA New = 28.9 amps + 1.6 amps = 30.5 amps If the new MCA does not exceed the published MOCP, then MOCP would not change. The

MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next larger size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.

C. EconoMi$er IV Standard Sensors

Outdoor Air Temperature (OAT) Sensor The outdoor air temperature sensor (HH57AC074) is a 10 to

20 mA device used to measure the outdoo r-air temperature. The outdoor-air temperature is used to determine when the EconoMi$ er IV ca n be used for free cooling. The sensor is factory-installed on the EconoMi$er IV in the outdoor airstream. See Fig. 16. The ope rating range of temperatu re measurement is 40 to 100 F.

Supply Air Temperature (SAT) Sensor The supply air temperature sensor is a 3 K thermistor

located at the inlet of the indoor fan. See Fig. 26. This sensor is factory installed. The operating range of temperature measurement is 0° to 158 F. See Table 3 for sensor temperature/resistance values.

The temperature sensor l ooks like an eyelet terminal with wires running to it. The sensor is located in the “crimp end” and is sealed from moisture.

D. EconoMi$er IV Control Modes

Determine the EconoMi$er IV control mode before set up of the control. Some modes of operation may require different sensors. Refer to Table 4. The EconoMi$er IV is supplied fr om the f actory with a supply air temperature sensor and an outdoor air temperature sensor. This allows for operation of the EconoMi$er IV with outdoor air dry bulb changeover control. Additional accessories can be added to allow for different types of changeover con tro l and op era ti on of the Econ oMi $e r IV and unit.

Outdoor Dry Bulb Changeover The standard controller is shippe d from the factory config-

ured 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 pr ovide fr ee cooli ng using o utdoor ai r. When in this mode, the LED next to the free cooling set point potentiometer will be on. T he changeover temperat ure set point is controlled by the free cooling set poi nt pote ntiometer locat ed on the control. Se e Fig. 27. Th e s cale on the pote n tio me ter is A, B, C, and D . See Fig. 28 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 senso r must be mounted in the return airstream. See Fig. 29. Wiring is provided in th e EconoMi$e r IV wiring harness. See Fig. 22.

—17—

Page 18

In this mode of operation, the outdoor air temperature is compared to the return air temperature and the lower temperature air stream is used for cooling. When using this mode of changeover control, turn the enthalpy setpoint potentiometer fully clockwise to the D setting. See Fig. 27.

Outdoor Enthalpy Changeover For enthalpy control, accessory enthalpy sensor (part num-

ber HH57AC078) is required. Replace the standard outdoor dry bulb temperature sensor with the accessory enthalpy sensor in the same mou nt ing lo ca tio n . Se e Fig. 16. 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 outdoo r enthalpy set point potentiometer on the EconoMi$er IV controller. The set points are A, B, C, and D. See Fig. 30. The factory-installed 620-ohm jumper must be in place across terminals SR and SR+ on the EconoMi$er IV controller. See Fig. 16 and 31.

Differential Enthalpy Control For differential enthalpy control, the EconoMi$er IV con-

troller 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 contro ll er selects the lowe r en thalpy 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 b r ing in outdoor air for free cooling.

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 spa ce 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. 32.

HIGH LIMIT CURVE

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 d am p er p o sit i on ( if ac ce ss or y pow e r ex ha ust i s installed). The set point is modified with the Exhaust Fan Set Point (EXH SET) potentiometer. See Fig. 27. 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 activation to allow the dampers to open. This delay allows the damper to reach the appropriate position to avoid unnecessary fan overload.

Minimum Position C o ntrol There is a minimum damper position potentiometer on the

EconoMi$er IV c o nt ro ll er. See Fig. 27. The mini mum 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 clock wi se.

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 proced ur e :

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

)+ (TR x

100 100

= Outdoor-Air Temperature

) = T

OA = Percent of Outdoor Air TR = Return-Air Temperature RA = Percent of Return Air TM = Mixed-Air Temperature As an example, if local codes require 10% outdoor air

during occupied conditions, outdoor-air temperature is 60 F, and 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 accor din g to Fig. 22 and that t he mi nimu m position potentiometer is turned fully clockwise.

4. Connect 24 vac across terminals TR and TR1.

5. Carefully adjust th e minim um positi on potent iomet er until the measured mixed-air temperature matches the calculated va lue.

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

Remote control of the EconoMi$er IV damper is desirable when requiring additional temporary ventilation. If a field-supplied remote potentiometer (Honeywell part number S963B1128) is wired to the E co no Mi$er IV controller, th e minimum position of the damper can be controlled from a remote location.

To control the minimum damper position remotely, remove the factory-insta lled jumper on the P and P1 terminals on the EconoMi$er IV controller. Wire the field-supplied potentiometer to the P and P1 termina ls on the EconoMi$er IV controller. See Fig. 31.

Damper Movement Damper movement from full open to full closed (or vice

versa) takes 2

/2 minutes. Thermostats The EconoMi$er IV control works with conventional thermo-

stats 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 do es not support space temperature sensors. Connections are made at the thermostat terminal connection board located in the main control box.

Occupancy Control The factory default configuration for the Econo Mi$er IV con -

trol is occupied mode. Occupied status 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 th e jumper between TR an d N. See Fig. 22. When the timeclock contacts are closed, the EconoMi$er I V control will be in occupied mode. When the timeclock contacts are open (removin g the 24-v signal from terminal N), the EconoMi$er IV will be in unoccupied mode.

Demand Controlled V enti lation (DCV) When using the EconoMi$er IV for demand controlled venti-

lation, 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 conditio ns. The maximum damper position must be calculated to provide the desired fresh air.

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

A proportional anticipatory strategy should be taken with the following conditions: a zone with a large area, varied occupancy, and equipm ent that cannot exceed the req uired ventilation rate at design con dition s. Exceeding th e requ ired ventilation rate means the equipment can co ndition air a t a maximum ventilation rate that is gre ater than the requ ired ventilation rate for maximum occupancy. A proportionalanticipatory strategy will cause the fresh air supplied to increase as the room CO

level increases even though the

CO2 set point has not been reached. By the time the CO level reaches the set point, the damper will be at 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 ventilat ion. Base v entilatio n 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.

(TO x T

)+ (TR x

100 100

= Outdoor-Air Temperature

) = T

OA = Percent of Outdoor Air TR = Return-Air Temperature RA = Percent of Return Air TM = Mixed-Air Temperature Once base ventilation has been determined, set the mini-

mum 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

—20—

Page 21

output of 3.6 volts t o the ac tuat o r pro vide s a ba se ve ntil at io n rate of 5% and an output of 6.7 volts provides the maximum ventilation rate of 20% (or bas e plu s 15 cfm pe r pers on). Use Fig. 32 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. 32 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 f rom th e CO

sensor to the actuator when the CO

concentration in the spac e is a t 1100 ppm . The D CV set point may be left at 2 volts since the CO

sensor voltage will be

ignored by the Econ oMi$er IV co ntroller u ntil it rises above the 3.6 volt setting of the minimum position potentiometer.

Once the fully occupied damper position has been determined, set the maximu m da mpe r de ma nd con t ro l ve nt il atio n 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.

Sensor Configuration

The CO2 sensor has preset standard voltage settings that can be selected anytime afte r the sensor is powere d up. See Table 5.

Use setting 1 or 2 f or Bryant equipment. See Table 5.

1. Press Clear and Mode buttons. Hold at least 5 seconds until the sensor enters the Edit mode.

2. Press Mode twice. The STDSET Menu will appear.

3. Use the Up/Down button to select the preset number. See Table 5.

4. Press Enter to lock in the selection.

5. Press Mode to exit and resume normal operation.

The custom settings of the CO

sensor can be changed any-

time after the s ensor is energiz ed. Follow the s teps belo w to change the non-standard settings:

1. Press Clear and Mode buttons. Hold at least 5 seconds until the sensor enters the Edit mode.

2. Press Mode twice. The STDSET Menu will appear.

3. Use the Up/Down button to toggle to the NONSTD menu and press Enter.

4. Use the Up/Down button to toggle through each of the nine variables, starting with Altitude, until the desired setting is reached.

5. Press Mode to move through the variables.

6. Press Enter to lock in the selection, then press Mode to continue to the next variable.

Dehumidification of Fresh Air with DCV Control Information from ASHRAE indicates that the largest humid-

ity load on any zone is the fresh air introduced. For some applications, an energy recove ry unit is added t o reduce the moisture content of the fresh air being brought into the building when the enthalpy is hi gh. In most cases, the no rmal heating and co oling proc esse s are m ore tha n ade quate to remove the humidity loads for most commercial applications.

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

PRE-START-UP

WARNING: Failure to observe the following warnings

could result in serious personal injury .

1. Follow recognized safety practices and wear protective goggles when checking or the servicing refrigerant system.

2. Do not o perate the compr essor or provi de any electric power to the unit unless the compres sor termina l cover is in place and secured.

3. Do not remo ve the com pre ssor termi nal cove r unti l all electrical sources are disconn ected.

4. Relieve all pressure from the system before touching or disturbing anything in side the c omp ress or term ina l box if refrigerant leak is suspected around the compressor terminals.

5. Never attempt to repair a soldered connection while the refrigerant system is under pressure.

6. Do not use to rch to remove any component. The sys tem contains oil and refrigerant under pressure. To remove a component, wear protective goggles and proceed as follows: a. Shut off gas and then electrical power to the unit.

Install lockout tag.

b. Relieve all pressure from the system using both

high-pressure and low-pressure ports.

c. Cut the component connection tubing with a tubing

cutter, and remove the component from the unit.

d. Carefully unsweat the remaining tubing stubs when

necessary. Oil can ignite when exposed to torch flame.

Proceed as follows to ins pect and prep are the unit f or 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, the unit.

3. Make the following inspections: a. Inspect for shipping and handling damages such

as broken lines, loose p arts, or discon nec ted 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 an electronic leak detector, halide torch, or liquid-soap solution.

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

Be sure that connections are completed and tight.

d. Inspect coil fins. If damaged during shipping and

handling, carefully straighten the fins with a fin comb.

4. Verify the following conditions: a. Make sure that condenser fan blade is correctly

positioned in the fan orifice. See Condenser-Fan

Adjustment section on page 39 for more details. b. Make sure that air filter(s) is in place. c. Make sure that condensate drain trap is filled

with water to ensure proper drainage. d. Make sure that all tools and miscellaneous loose

parts have been removed.

START-UP

I. UNIT PREPARATION

Make sure that unit has bee n installed in accordance with these installation instructions and applicable codes. Make

sure Start-Up Checklist on back page is filled out and completed.

II. RETURN-AIR FILTERS

Make sure correct filters are installed in filter tracks. See Table 1. Do not operate unit without return-air filters.

III. COMPRESSOR MOUNTING

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

IV INTERNAL WIRING

Check all electrical connections in unit control boxes. Tighten as required. Ensure wiring does not come in contact with refrigerant tubing.

V. GAS PIPING

Check gas piping for leaks.

WARNING: Disconnect gas piping from unit when

leak testing at pressure greater than

sures greater tha n

/2 psig will cause g as valve damage

/2 psig. Pres-

resulting in hazardous condition. If gas valve is subjected to pressure greater than

/2 psig, it must be replaced before use. When pressure testing fieldsupplied gas piping at pressures of

/2 psig or less, a unit connected to such piping must be isolated by manually closing the gas valve.

VI. REFRIGERANT SERVICE PORTS

To service refrigerant service ports, remove compressor access panel. 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. One of the Schrader-type valves on the compressor discharge line is located under the low-pressure switch.

The Schrader valve on the compr essor di scharge li ne that is located under the high pressure switch does not contain a Schrader core in the valve.

VII. HIGH FLOW VALVES

Located on the compressor hot gas and suction tubes are high flow valves. Large black plastic caps distinguis h these valves with o- r in gs located inside the ca ps. These valv es ca nnot be accessed for service in the field. Ensure the plastic caps are in place and tight or the possibility of refrigerant leakage could occur.

VIII. COMPRESSOR ROTATION

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

1. Connect service gage s 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 evaporator fan is probably also rotating in the wrong direction.

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

3. Reverse any two of the unit power leads.

4. Reapply power to the unit.

—35—

Page 36

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

NOTE: When the compres sor is rotating in th e wrong direction, the unit makes an elevated level of noise and does not provide cooling.

IX. COOLING

Set space thermostat to OFF 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, outdoor fan and evaporator motor start on closure of contactor.

Check unit charge. Refer to Refrigerant Charge section, page 39.

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 system selector switch at OFF position. Resetting thermostat at a position ab ove room temperature shu ts unit off temporarily until space temperature exceeds thermostat setting.

X. MAIN BURNERS

Main burners are factory set and should require no adjustment.

TO CHECK ignition of main burners and heating controls, move thermostat set p oint abov e room tem perature a nd 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.)

Refer to Table 33A and 33B for the correct orifice to use at high altitudes.

XI. HEATING

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

2. Turn on electrical supply and manual gas val ve .

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 wil l turn on 45 seconds after the burners are ignited.

7. The evaporator-fan motor will turn off 45 seconds after thermo st a t te m p e r at u r e i s sa t isfied.

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 is observed, t he evaporator-fan ON/OFF delay has been modified.

If the limit switch trips at the start of the heating cycle during the evap or ator ON delay, t he ti me period of the ON de lay for the next cycle will be 5 seconds less than the time at which the swit ch trip ped. (Exa mple: If th e l imit switch trip s at 30 seconds, t he ev aporator-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. 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 bel ow room temperature will temporar ily shut unit off until space temperature falls be low therm ostat setting.

XII. SAFETY RELIEF

A soft solder joint at the suction service Schrader port provides pressure relief under abnormal temperature and pressure conditions (i.e., fire in building).

XIII. VENTILATION (CONTINUOUS FAN)

Set fan and system selector switches at ON and OFF positions, respectively. Evaporator fan operates continuous ly to provide constant air circulation. When the evaporator-fan selector switch is turned to the OFF position, there is a 30-second del a y be f or e th e f an tur ns off.

XIV. OPERATING SEQUENCE

A. Cooling, Units without EconoMi$er IV

When thermostat calls for cooling, terminals G and Y1 and the compressor contactor (C) are energized. The indoor (evaporator) fan motor (IFM), compressor, and outdoor (condenser) fan motor (OFM) start. The OFM runs continuously while the unit is in cooling. When the thermostat is satisfied, C is deenergized and the compressor and OFM shut off. After a 30-second delay, the (IFM) shuts off. If the thermostat fan selector switch is in the ON position, the evaporator motor will run continuously.

B. Heating, Units without EconoMi$er IV

When the thermostat call s for heatin g, terminal W1 is energized. The induced-draft motor is energized and the burner ignition seque nce begins. The indoor (evaporator) f an motor (IFM) is energized 45 seconds after a flame is ignited. When additional he at is n eeded, W 2 is en ergized and t he high- fire solenoid on the main gas valve (MGV) is energized. When the thermostat is satis fied and W1 is deenergized, the IFM stops after a 45-second time-off delay.

C. Cooling, Units with EconoMi$er IV

When free cooling is not avail able, the compressors will be controlled b y th e zone ther mosta t. Wh en f ree co oling is a vai lable, 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 be lo w 50 F, the dampers will be modulated (open or close) to bring the supply-air temperature back within 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.

Above 50 F supply-air temperature, the dampers will modulate from 100% o pen to the minimum open po sition. From 50 F to 45 F supply-air temperature, the dampers will maintain at the minimum open position. Below 45 F the dampers will be completely shut. As the supply-air temperature rises, the dampers will com e ba ck ope n to the mini mu m ope n posi tion once the supply-air temperature rises to 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

sensors are connected to the

EconoMi$er IV control, a demand controlled ventilation

strategy will begin to o perate. As the CO

level in the zone

increases above the CO2 set point, the minimum position of the damper wi ll be i ncr eased pro port ional ly. As the CO

level

decreases 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.

On the initial power to the EconoMi$er IV control, it will take the damper up to 2

/2 minutes before it begins to position itself. Any change in damper position will take up to 30 seconds to initiate. Damper movement from full closed to full open (or vice versa) will take bet we en 1

/2 and 21/2 minutes.

If free cooling can be used as determined from the appropriate changeover com mand (switch, dr y 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 a ir temperature set point at 50 to 55 F.

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

D. Heating, Units with EconoMi$er IV

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.

VII. REFRIGERANT CHARGE

Amount of refrigerant charge is listed on unit nameplate (also refer to Table 1). Compressor must run a minimum of 10 minutes before adjus ting or checki ng charge.

Unit panels must be in place when unit is operating during charging procedure.

A. No Charge

Use standard evacuating techniques. After evacuating system, to 500 microns, weigh in the specified amount of refrigerant. (Refer to Table 1.)

B. Low-Charge Cooling

Using Cooling Charging Charts, Fig. 40-43, vary refrigerant until the conditions of the appropriate chart are met. Note the charging charts a re different from type normall y used. Charts are based on charging the units t o the correct superheat for the var ious op erating c onditio ns. Accurate pr essure gage and temperature sensing device are required. Do not use pocket type thermometers for measuring surface temperatures as they are not designed for this type of measurement. Connect the pressure gage to the service port on the suction line. Mount the temperature sensing device on the suction line and insula te it so that ou tdoor am bient temper ature does not affect the reading. Indoor-air cfm must be within the normal operating range of the unit.

C. To Use Cooling Charging Chart

Take the outdoor ambient temperature and read the suction pressure gage. Refer to chart to determine what suction temperature should be. If suction temperature is high, add refrigerant. If suction temp erature is low, carefully recover some of the charge. Recheck the suction pressure as charge is adjusted .
