SAFETY CONSIDERATIONS

Installation and servicing 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 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.

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

CAUTION: Ensure voltage listed on unit data plate agrees with electrical supply provided for the unit.

INSTALLATION

Unit is shipped in the vertical discharge configuration. To convert to horizontal configu rat ion, remov e scre ws from horizontal duct opening covers and remove covers. Using the same screws, install covers on duct openings in basepan of unit with the insulation-side down. Seals around duct openings must be tight. See Fig. 1.

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 access ory roof curb in accorda nce with instructions shipped with curb. See Fig. 2. Install insulation, cant strips, roofi ng fe lt, and counter flashing as shown. Duct- work must be attached to curb, not to unit. If electric control power is to be routed through the basepan, attach the accessory thru-the-bottom service connec tions to the roof curb in accordance with the accessory installa tion instructions. Connection must be installed before unit is set on roof curb.

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. 2. Improperly applied gasket can also result in air leaks and poor unit performance.

Curb should be level. This is necessar y for unit drain to function properly. Unit leveling tolerances are shown in Fig. 3. Refer to Accessory Roof Curb Installation Instructions for additional information as required.

B. Alternate Unit Support

When the curb or adapter cannot be used, support unit with sleeper rails using unit curb or adapter support area. If sleepers cannot be used, support long sides of unit with a minimum of three 4-in. x 4-in. pads, 2 at the unit’s corners and one at the center of gravity. If more than 3 are used, equally space out pads along unit side.

C. Slab Mount (Horizontal Units Only)

Provide a level concrete slab that ex te nds a m ini mum o f 6 i n. beyond unit cabinet. Install a 6-in. gravel apron in front of outdoor-coil air inlet to prevent grass and foliage from obstructing airflow.

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

II. STEP 2 — FIELD FABRICATE DUCTWORK

On vertical discharge un its, secure all ducts to ro of c urb and building structure. Do not connect ductwork to unit. For horizontal applications, field-supplied isolation flanges should b e attached to horizontal discharge openi ngs and all ductwork attached to the flanges. Insulate and weatherproof all e xternal ductwork, joints, and roof openings with counter flashing and mastic in accordance with applicable codes.

Fig. 1 — Horizontal Conversion Panels

Ducts passing through a n unc ondit i one d spa ce must be insulated and covered with a vapor barrier.

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

If electrical connections are to be routed thro ugh the bottom of the unit, atta ch ac cess ory th ru-t he- bottom s ervi ce con nect ions to the basepan in accordance with installation instructions.

A minimum clearance is not required around ductwork. Cabinet return-air static pressure (a negative condition) should not exceed 0.30 in. wg with economizer or 0.45 in. wg without economizer.

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, ensure the plug in the alternate bottom connection (in center of pan) is tight before installing the unit.

To use the bottom drain connection for a roof curb installation, relocate the factory-installed plug 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 freeze-up. If a dra in line is installe d 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 (

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

The center drain plug looks lik e a star conne ctio n, however it can be removed with a

/2 in. socket drive extensio n.

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 reference. See Tables 1A and 1B and Fig. 6 for additional inf ormat ion. Op era ting we ight is s hown in Tables 1A and 1B and Fig. 6.

Lifting holes are provided in base rails as shown in Fig. 6 and 7A and 7B. Refer to rigging instructions on unit.

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

A. Positioning

Maintain clearance around and above unit to provide proper airflow and service access. See Fig. 7A and 7B.

Position unit on roof curb so that the following clearances are maintained:

/4-in. clearance between roof curb and base rails on duct end, front and back of unit; 35/16-in. clearance between roof curb and condenser fan end of un it (see Fig. 2, sections A-A and C-C).

Do not install unit in an indoor l ocation. Do not locate unit air inlet near exhaust vents or other sources o f c ontam ina t ed air.

Although unit is weatherproof, guard against water from higher level runoff and overhangs.

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

V. STEP 5 — MAKE ELECTRICAL CONNECTIONS

WARNING: Unit cabinet must have an uninter-

rupted, unbroken electrical ground to minimize the possibility of personal injury if an electrical fault should occur. This ground may consist of elec tric al wire connected to unit ground lug in control compartment, or conduit approved for electrical ground when installed in accordance with NEC (Nati onal Electrical Code), ANSI/NFPA (American National Standards Institute/National Fire Protection Association), latest edition, and local electrical codes. Failure to follow this warning could result in the installer being liable for personal injury of others.

A. Field Power Supply

All units except 208/230-v units are factory wired for the voltage shown on the na meplate. If the 208/230-v un it is to be connected to a 208-v power supply, the transformer must be rewired by moving the black wire from the 230-v

/4-in. male spade terminal on the transformer and connecting it to the 200-v

/4-in. male spade terminal on the transformer.

Refer to unit label diagram for additional information . Pigtails are provided for field wire connecti ons.

When installing units, provide a disconnect per NEC. Use copper conductors only when splice connectors are used.

NOTE: When accessory thru-the-bottom connections are used, refer to the accessory installation instructions for information on power wiring. Refer to Fig. 7A and 7B for drilling locations.

All field wiring must comply with NEC and local requirements. In Canada, electr ical connections must be in accordance with CSA (Canadian Standards Association) C22.1 Canadian Electrical Code Part One.

Install field wiring as follows (see Fig. 8-10):

1. Instal l conduit th rough side p anel opening s between disconnect and single point box (see Fig. 9 and 10).

2. Install powe r w ire s to t erm ina l conn ect ions as sho wn in Fig. 8.

Voltage to compressor terminals during operation must be within voltage range indicated on unit nameplate (see Tables 2A-2D). 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 percentage 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 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.

Route thermostat ca ble or equivalent si ngle leads of col ored wire from subbase terminals to low-voltage connections on unit (shown in Fig. 11) as described in Steps 1-5 below.

NOTE: For wire runs up to 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 75 ft, use no. 14 AWG insulated wire (35 C minimum). All wire larger than no. 18 AWG cannot be directly c onn ected to the thermost at and wi ll requi re a junct ion box and splic e at the thermostat.

1. If unit is mounte d on roof curb and accessory thruthe-bottom connection is used, route wire through connector provided in accessory kit through the unit basepan.

2. Pass control wires thro ugh the hole prov ided on unit (see connection D, Connection Sizes Table, Fig. 7A and 7B).

3. Feed wire through the raceway built into the corner post to the 24-v barrier located on the left side of the control box. See Fig. 12. The raceway provides the UL-required (Underwriters’ Laboratories) clearance between the high-and low-voltage wiring.

4. Connect thermos tat wires to screw term inals of lowvoltage terminal board.

5. If unit is to be equipped with electric resistance heat, ensure thermostat on a call for heat “W” energizes “G” output. This allows fan operation on a call for heat.

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 558FPX091000 unit with MCA = 40.1 and MOCP = 45, with

CRPWREXH030A01 power exhaust. MCA New = 40.1 amps + 1.6 amps = 41.7 amps If the new MCA does not exceed the published MOCP, then MOCP would not change.

The MOCP in this example is 45 amps, the MCA New is below 45, 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.

3. For units with power exhaust: If a single power source is to be used, size wire to include power exhaust MCA and MOC P. Check MCA and MOCP whe n power exhaust is powered throu gh the unit (must be in accordance with NEC and/or local codes). Determine the new MCA including the power exhaust using the following form ula: MCA New = MCA unit only + MCA of Power Exhaust For example, using a 558FPX091000 unit with MCA = 40.1 and MOCP = 45, with CRPWREXH030A01 power exhaust. MCA New = 40.1 amps + 1.6 amps = 41.7 amps If the new MCA does not exceed the published MO CP, then MOCP would not change. The MOCP in this example is 45 amps, the MCA New is below 45, 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.

1. In compliance with NEC requirem ents for multimotor a nd combination lo ad equipment ( refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. Canadian units may be fuse or circuit breaker.

2. Unbalanced 3-Phase Supply Voltage

Never operate a motor where a ph ase imbalance in sup ply voltage is greater than 2%.

following formula to determine the percent of voltage imbalance. % Voltage Imbalance

= 100 x

Determine maximum deviation from average voltage.

(AB) 457 – 452 = 5 v (BC) 464 – 457 = 7 v

(AC) 457 – 455 = 2 v Maximum deviation is 7 v. Determine perc ent of voltage imbalance.

% Voltage Imbalance = 100 x

This amount of phas e imbalance is satisfacto ry as it is below the max imum allowable 2%.

MCA New = MCA unit only + MCA of Power Exhaust For example, using a 558FPX091000 unit with MCA = 40.1 and MOCP = 45, with CRPWREXH030A01 power exhaust. MCA New = 40.1 amps + 1.6 amps = 41.7 amps If the new MCA does not exceed the published MO CP, then MOCP would not change. The MOCP

in this example is 45 amps, the MCA New is below 45, 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.

2. Unbalanced 3-Phase Supply Voltage

Never operate a motor where a phase imbalance in supply voltage is greater than 2%.

the following formula to determine the percent of voltage imbalance. % Voltage Imbalance

= 100 x

Determine maximum deviation from average voltage.

(AB) 457 – 452 = 5 v (BC) 464 – 457 = 7 v

(AC) 457 – 455 = 2 v 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%.

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 temperatur e 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 positi on. If the outdoor-air temperature is below the set point, the position of t he 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. Th e changeover temperatu re set point is controlled by the free cooling set poi nt pote ntio meter located on the control. Se e Fig. 28. Th e s cale on the pote n tio me ter is A, B, C, and D . See Fig. 29 for the corresponding temperature changeover values.

In this mode of operation, the outdoor-air temperature is compared to the return-air temperature and the l ower temperature airstream is used for cooling. When using this mode of changeover control, turn the enthalpy set point potentiometer fully clockwise to the D setting. See Fig. 28.

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. 17. 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$er IV controller. The set points are A, B, C, and D. See Fig. 31. The factory-installed 620-ohm jumper must be in place across terminals SR and SR+ on the EconoMi$er IV controller. See Fig. 17 and 32.

Differential Ent halpy 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 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.

Replace the standard outside air d ry bulb temperatu re sensor with the accessory enthalpy sensor in the same mounting location. See Fig. 17. Mount the return air enthalpy sensor in the return air duct. See Fig. 30. Wiring is provided in the EconoMi$er IV wiring harness. See Fig. 23. The outdoor enthalpy changeover set point is set with the outdoor enthalpy set point potentiometer on the EconoMi$er IV controller. When using this mode of chan geover control, turn the enthalpy s et point 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 sp ace or

return air duct. Mount the accessory IAQ sensor according to manufacturer

specifica t io n s. The IAQ sen so r sh ould 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. 33.

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. 28. 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. 2 8. T h e m ini 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 betwee n 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 x

) = T

TO = Outdoor-Air Temperature 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 tha t 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. 23 and that t he mi nim um position potentiometer is turned fully clockwise.

4. Connect 24 vac across terminals TR and TR1.

5. Carefully adjust the mi nimum po sition po tentiome ter until the measured mixed air temperature matches the calculated va lue.

6. Reconnect the su pply air sensor to terminals T and T1.

Remote control of the EconoMi$er IV damper is desirable when requiring additional temporary ventilation. If a fieldsupplied remote potentiometer (Honeywell part number S963B1128) is wired to the EconoMi$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-insta lled jumper on the P and P1 terminals on the EconoMi$er IV controller. Wire the field-supplied potentiometer to the P and P1 terminals on the EconoMi$er IV controller. See Fig. 32.

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

versa) takes 21/2 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 does not support space temperature sensors. Connections are made at the thermostat terminal connection board located in the main control box.

Occupancy Control The factory d efa ul t c on fi guration for th e E con oMi $e r IV co n-

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 the jumper between TR and N. See Fig. 23. When the timeclock contacts are clos ed, the EconoMi$e r IV control will be in occupied mode. When the timeclock contacts are open (r emoving the 24-v si gnal from terminal N) , the EconoMi$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 required ventilation rate at design con diti ons. Exceedin g the req uir ed ventilation rate means the equipment can co ndition air a t a maximum ventilation rate that is greater than the required ventilation rate for maximum occupancy. A proportionalanticipatory strategy will cause the fresh air supplied to increase as the room CO CO

set point has not been reached. By the time the CO

level increases even though the

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 ventilation. Base ve ntilation is t he 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

= Outdoor-Air Temperature

)+ (TR x

100 100

) = 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 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 t he act uat o r pro vid es a ba se v e ntil at io n 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. 33 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. 33 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 sho uld

be 1800 ppm. The EconoMi$er IV controller will output the

6.7 volts from the CO

sensor to the actuator when the C O

concentration in the spa ce i s at 110 0 ppm. The DCV se t point may be left at 2 volts since the CO

sensor voltag e will be

ignored by the EconoMi$e r IV cont roller unt il 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 maxim um 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 humid-

ity load on any zone is the fresh air introduced. For some applications, a device such as an 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 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 considered.

PRE-START-UP

WARNING: Failure to observe the following warn-

ings could result in serious personal injury:

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

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

3. Do not remove compressor termin al cover until all electrical sou rc e s are disco nnected.

4. Relieve all pressure from system before touching or disturbing anything inside terminal box if refrigerant leak is su spe cte d arou nd c ompre ssor terminals. Use accepted meth ods to reco ver refrigerant.

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

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

a. Shut off electrical power to unit. b. Recover refrigerant to relieve all pressure

from system using both high-pressure and low-pressure ports.

c. Cut component-connecting tubing with

tubing cutter and remove component from unit.

d. Carefully unsweat 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, unit.

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

as broken lines, loose parts, 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 a nd factory-wiring connec-

tions. Be sure that connections are completed and tight. Ensure electrical wires do not come in contact with refrigerant lines or sharp edges.

d. Inspect coil fins. If damaged during shipping and

handling, care full y str ai ght en fins w ith a f in comb.

4. Verify the following conditions:

a. Make sure that condenser-fan blade is positioned

correctly in fan orifice. Blades should clear fan motor and fan orifice ring.

b. Make sure that air filters are in place. (See

Tables 1A and 1B.) Do not operat e unit without return-air filters.

c. Make sure that the condensate drain pan and

trap are filled with water to ensure proper drainage.

d. Make sure that all tools and miscellaneous loose

parts have been removed.

e. Make sure outdoor-air inlet screens are in place.

5. Compressors are internally s pring mounted. Do not loosen or remove co mpressor holddown bolt s.

6. Each unit system has 3 Schrader-type service ports: one on the su ction line, one on the liquid line and one on the compressor discha rge line. Be sure that caps on the ports are tight.

7. Ensure electrical wires do not make contact with refrigerant lines.

START-UP

I. UNIT PREPARATION

Make sure that unit has b een installed in accordance with these installation instructions and applicable codes. Ensure Start-Up Checklist on back page of booklet is completely filled out.

II. RETURN-AIR FILTERS

Make sure correct air filters are installed in unit (see Tables 1A and 1B). Do not operate unit without return-air filters.

III. OUTDOOR-AIR INLET SCREENS

Outdoor-air inlet screen(s) must be in place before oper ating unit.

IV. COMPRESSOR MOUNTING

Compressors are internally spring mounted. Do not loosen or remove compressor holddown bolts. Remove the tiedown bands that hold the compressors together on 558F103,121,150,151 units.

V. INTERNAL WIRING

Check all electrical conne c tion s in unit c o ntrol b oxe s; tig hte n as required. Verify and correct if necessary. Ensure that electrical component wiring does not come in contact with refrigerant tubin g or sharp edges.

VI. REFRIGERANT SERVICE PORTS

To service refrigerant service ports, remove compressor access panel. Each unit system has 3 Schrader-type service gage ports: one on the suction line, one on the liquid line, and one on the compressor discharg e line. Be sure that caps on the ports are tight. The Schrader-type valve on the discharge line is located under th e low-pressu re switch. Anoth er valve is located on the discharge line underneath the highpressure switch. It is screwed on a Schrader fitting but there is no Schrader core.

A. 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-ri ng s in side wh ich sc rew the ca p on to a brass body to prev e n t l ea ks. 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 o f refrigerant leakage could occur.

VII. COMPRESSOR ROTATION

On 3-phase scroll compressor un its (103,121,150,1 51), it is important to be certain compres sor is rotating in the prope r direction. To determine whether or not compres sor is rotating in the proper direction:

1. Connect service g ages to suction and discharge pres sure fittings.

—54—

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, tag disconnect.

3. Reverse any two of the unit power leads.

4. Turn on power to the unit.

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 an elevated level of noise and does not provide cooling.

VIII. COOLING

To start unit, turn on m ain power supply. Set system selector switch at CO OL positi on and fan switch at AUT O. position. Adjust thermostat to a setting below room temperature. Compressor starts on closure of contactor.

Check unit charge. Refer to Refrigerant Charge section on page 57. Unit must operate a minimum of 10 minutes before adjusting charge.

Reset thermostat at a position above room temperature. Compressor will shut off.

A. To Shut Off Unit

Set system selector switch at OFF position. Resetting t hermostat at a position above room temperature shuts unit off t emporarily until space temperature exceeds thermostat sett ing.

IX. HEATING (If Accessory Electric Heater is Installed)

To start unit, turn on main power supply. Set thermostat at HEAT position and a setting above room

temperature, and set fan at AUTO. position. First stage of thermostat energizes the first-stage electric

heater; second stage energizes second-stage electric heater elements, if installed. Check air supply grille(s) to ensure proper heat supply.

If unit does not energize, reset limit switch (located on evaporator-fan scroll) by pressing button located between terminals on the switch.

A. To Shut Off Unit

Set system selector sw itch at OFF p osition. Re setting h eating selector lever below room temperature will shut unit off temporarily until space temperature falls below thermostat setting.

X. SAFETY RELIEF

A soft solder joint in the suction line at the low-pressure service port provides pressure relief under abnormal temperature and pressure conditions.

XI. VENTILATION (Continuous Fan)

Set fan and system selector switches at ON and OFF positions, respectively. Evaporator fan operates continuous ly to provide air circulation.

XII. OPERATING SEQUENCE A. Cooling, Units Without EconoMi$er IV

When thermostat calls for cooling, terminals G and Y1 are energized. The indoor (evaporator) fan contactor (IFC) and compressor contactor no. 1 (C1) are energized, and evaporator-fan motors, compressor no. 1, and condenser fans start. The condenser-fan motor runs continuously while unit

is cooling. For units with 2 stages of cooling, if the thermostat calls for a second stage of cooling by energizing Y2, compressor contactor no. 2 (C2) is energized and compressor no. 2 starts.

When the thermostat is satisfied, C1 and C2 are deenergized and the compressors and outdoor (condenser) fan motors (OFM) shut off. After a 30-second d elay, the indoor (evaporator) fan motor (IFM) shuts off. If the thermostat fan selector switch is in the ON positio n, the evaporator motor will run continuously.

B. Heating, Units Without EconoMi$er IV (If Optional or Accessory Heater is Installed)

Upon a call for heating through terminal W1, IFC and heater contactor no. 1 (HC1) are energized. On units equipped for 2 stage s of h eat, w hen addi t ion al he at i s ne ede d HC2 is energized thro ugh W2.

C. Cooling, Units With EconoMi$er IV

When free cool ing is not available, the com pressors will be controlled b y th e zo ne th ermost at. When f re e cool ing i s a vailable, 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 5 0 F, the dampers will be modulated (open or close) to bring the supply-air temperature back within set points limits.

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% open to the minimum open position. 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 come back open to the minimum open position 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 opera te. As the CO increases abo ve the CO

set point, the minimum position of

the damper will be increased proportionally. As the CO

level in the zone

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.

Damper movement from full closed to full open (or vice versa) will take between 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 below the set point range of 50 to 55 F, t he 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 EconoMi$er IV section. When the thermostat is satisfied, the economizer damper moves to the minimum position.

V. MANUAL OUTDOOR-AIR DAMPER

If outdoor-air damper blade adjustment is required, see Manual Outdoor-Air Damper section on page 22.

VI. ECONOMIZER ADJUSTMENT

Refer to Optional EconoMi$er IV section on page 23.

VII. REFRIGERANT CHARGE

A. Checking and Adjusting Refrigerant Charge

The refrigerant system is fully charged with R-22 refrigerant, tested, and factory-sealed. Unit must operate in Cooling mode a minimum of 10 minutes before checking charge.

NOTE: Adjustment of the refrigerant charge is not required unless the unit is suspected of not having the proper R-22 charge.

A superheat charging chart is attached to the outside of the service access panel. The chart includes the re qui red suction line temperature at given suction line pressures and outdoor ambient te mp eratures .

An accurate superheat, thermocouple-type or thermistortype thermometer, and a gage manifold are required when using the superheat charging method for evaluating the unit charge. Do not use mercury or sm all dial-type thermometers

because they are not adequate for this type of m easurement.

CAUTION: When evaluating the refrigerant charge, an indicated adjustment to the specified factory charge must alw ay s be very minima l. If a substa ntial adjustment is indicated, an abnormal condition exists somewhere in the cool ing system , such as in sufficient airflow across either coil or both coils.

Proceed as follows:

1. Remove caps from low-pressure and high-pressure service fittings.

2. Using hoses with valve core depressors, attach lowpressure and high-pressure gage hoses to lowpressure and high-pressure service fittings, respectively.

3. Start unit in Cooling Mode and let unit run until system pressures stabilize.

4. Measure and record the following: a. Outdoor ambient-air temperature (F db). b. Evaporator inlet-air temperature (F wb). c. Suction-tube temperature (F) at low-side service

fitting.

d. Suction (low-side) pressure (psig).

5. Using “Cooling Charging Charts” compare outdoorair temperature (F db) with the suction line pressure (psig) to determine desired system operating suction line temperature. Se e Fi g. 41-48.

6. Compare actual suction-tube temperature with desired suction-tube temperature. Using a tolerance of ± 3° F, add refrigerant if actual temperature is more than 3° F higher than proper suction-tube temperature, or remove refrigerant if actual temperature is more than 3° F lower than required suction- tube temperature.

B. To Use Cooling Charging Charts

This method is to be use d in Co olin g m ode on ly. Take the o utdoor ambient temperature and read the suction pressure gage. Refer to appropriate chart to determin e what suction temperature should be. If suction temperature is high, add refrigerant. If suction temp erature is low, careful ly recover some of the charge. Recheck the suction pressure as charge is adjusted.
