SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should install, repair, or service air-conditioning equipment.

Untrained personnel can perform basic maintenance functions of cleaning coils and filters and replacing filters. All other operations 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 shall not exceed –.20 in. wg with economizer or –.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; eit her 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 li ne away fr om th e unit a t 1 i n. per 10 ft of run . 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.

A. Positioning

Maintain clearan ce around and above un it to provide minimum distance from combustible materials, proper airflow, and service access. See Fig. 1A a nd 1B. A properly positioned unit will have the follo wing c l ea ranc es betw een unit a nd r oof

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. (S ee 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 dire ctly on wood flooring or on Class A, B, or C roof-covering material when roo f 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 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.

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

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

CRPWREXH030A00 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+ Control Mode

Determine the EconoMi$er+ control mode before installing sensors and accessories. Different sensors are required for different control modes, and a number of accessories are available. R efer to Tables 3 and 4.

Outdoor Dry Bulb Changeover The standard control mode for the EconoMi$er+ is Outdoor

Dry Bulb Changeover. The outdoor air an d supply air temperature sensors are also included as standard. EconoMi$er+ control is based on the outdoor temperature relative to a set point in the software. If the outdoor air

temperature is above the set point then the EconoMi$er should be in minim um position. If the outdoor air tem perature is below the set point, the position should be controlled to maintain the leaving air temperature set point. The set point range is 45 to 70 F.

Differential D r y Bulb Changeover The control supports differential dry bulb changeover con-

trol. This requires an accessory return air temperature sensor CRTEMPSN001A00 installed in the return airstream. Refer to the Start-up section for details on how to configure and enable the control mode. The user can check the operation of the s ensor using the Read function.

Outdoor Air Enthalpy Changeover The control supports outside air enthalpy changeover con-

trol. This mode requires a factory-supplied outdoor air temperature sensor (OAT) and an accessory outdoor air humidity sensor (ORH) (part no. CRHUMDSN001B00). Refer to the Start-Up section for details on how to configure and enable the contro l mode. The user can check the o peration of the sensors using the Read function.

Differential Ent halpy Changeover The control supports differential enthalpy changeover con-

trol. This requir es the factory -supplied ou tside air tempera ture sensor, an accessory outdoor air humidity sensor, an accessory return air temperature sensor, and an accessory indoor air humidi ty sensor. Refer to the Start-Up section fo r details on how to configure and enable the control mode. The user can check the o peration of the sens ors using the Read function.

D. Damper Movement

When the EconoMi$e r+ board receives initia l power, it will take the damper up to 2

/2 minutes before it begins to position itself. After the initial positioning, subsequent changes to damper position will take up to 30 seconds to initiate. Damper movement from full open to full closed (or vice versa) takes 2

/2 minutes.

If the damper is in the process of changing positions (for example it is trying to open to 100%) and the fan signal is turned off, the damper will con tinue to its 100% open position before closing.

NOTE: Occupied minimum position can not be set lower than +1% higher than the value of IAQ minimum economizer position. Refer to the setup examples on page 42.

E. EconoMi$er+ Controller Wiring

The EconoMi$er+ is sup plied fr om the factory with a supply air temperature sensor and an outside air temperature sensor. This allows for op eration of the EconoMi$e r+ with outside air dry bulb changeover control. Additional accessories can be added to allow for different types of change over control and operation of the EconoMi$er+ and unit.

F. T hermostats

The EconoMi$er+ co ntrol works with conventional t hermostats that have a Y1 (cool stage 1), Y2 (cool stage 2), W1 (heat stage 1), W2 (heat stage 2), and G (fan). The EconoMi$er+ control does not support sensor thermostats like the T56 and T57. Connections are made at the thermostat terminal connection board located in the main control box.

I. Indoor Air Quality (IAQ) Sensor

Any indoor air quality or CO 20 mA output can be used as the IAQ sensor. The controller will modulate the o utdoor-air damper to pr ovide ventilati on based on the sensor output and the IAQ setting of the controller . The CO from the minimum po sition ( IAQ minimum damper po sition set point) to the maximum position (occupied minimum damper positi on). When th ere i s no CO go to the unoccupied minimum position. When there is a CO call, the damper will be between the IAQ minimum economizer set point position and the occupied minimum damper position.

Mount the sensor according to manufacturer specifications. In order to wire this sensor, an accessory 5-pin plug (part number CRE+PLUG001A00) is required. See Fig. 22.

The IAQ sensor is wired to the g round a nd IAQ w ires in the harness. The a ccesso r y 5-pin wi ring plug is c onnec ted to pi ns 13-17 of J3 on the EconoMi$er+ controller. Push the plug

G. Outdoor Air Temperature (OAT) Sensor (Provided)

The outdoor air tem peratur e sens or is a 10K therm isto r used to measure the o ut door-air temp erat ure. T he se nso r c on tro ls EconoMi$er+ changeover and compressor lockout. The sensor is factory-installed on the EconoMi$er+ in the outdoor airstream. The operating range of temperature measurement is 0° to 158 F. See Tables 5 and 6 for thermistor resistance and resolution 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.

The user can read the value of the sensor using the Read mode, described in the Start-Up section.

H. Supply Air Temperature (SAT) Sensor (Provided)

The supply air temperature sensor is a 10K thermistor located at the inlet to the indoor fan. This sensor must be field installed . Th e o per ating range of temperature me as ur ement is 0° to 158 F. See Tables 5 and 6 for thermistor resistance and resolution 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.

The user can read the value of the sensor using the Read mode, described in the EconoMi$er+ Controller section.

Pins 13 and 14 are used for the IAQ sensor. Pins 15-17 are used for the field-installed remote potentiometer. Connect the IAQ sensor to the BRN and WHT wires o f the accessor y 5-pin plug.

NOTE: Pin numbers are not shown on the controller. They are provided only as reference for the installer. On the EconoMi$er+ board, they numbered 1-17 from left to right, but only the 1 and the 17 are printed on the board.

Sensor wiring should be extended with wire and wire nuts and routed to the IAQ sensor location. Adjust the IAQ setting at the controller to correspond to the IAQ voltage output of the sensor at the user-determined set point. See Fig. 26. Power the sensor with a field-supplied transformer.

J. Return Air Temperature (RAT) Sensor

The EconoMi$er+ controller will accept input from the accessory 10K return air temperature sensor (CRTEMPSN001A00) in addition to the outdoor air temperature sensor shipped with the EconoMi$er+. By using both sensors, the outdoor air and the return air temp eratures are compared (differential dry bulb) for optimal energy savings. See Tables 5 and 6 for thermistor resistance and resolution values.

The user can read the value of the sensor using the Read mode, described in the EconoMi$er+ Controller section.

Mount the return air temperature sensor on the EconoMi$er+, through pre-punched holes. See Fig. 27.

The return air temperature (RAT) sensor is provided with a 2-wire, 42-in. long wiring harness with a 2-pin connector. The plug is installed on pins 5 and 6 on J3 of the EconoMi$er+ controller. The pins are labeled with a ground symbol and RAT on the EconoMi$er+ controller . See Fig. 22. The red wire of the harness is connected to pin 5 (ground). The black wire of the harness is connected to pin 6 (RAT). The wiring harness should be routed from the EconoMi$er+ controller to the sensor. The controller compares the temperatures of the two airstreams, chooses the best one, and modulates the EconoMi$er+ actuator accordingly.

This 10K thermistor is used to measure the return air temperature vs. resistance cu rve, per Table 5. The range of temperature measurement is between 0° and 158 F. See Table 6 for resolution.

K. Outdoor Air Humidity Sensor

The EconoMi $er+ con tro ller accep ts inpu t fro m the acc ess ory outdoor air humidity sensor in addition to the outdoor air temperature s en sor s hip pe d w ith th e Eco no M i$ er + . By us ing both sensors, the total enthalpy of the outside air is calculated.

Mount the outdoor-air humidity sensor in to the EconoMi$er+, through the pre-punched holes. See Fig. 28. The outdoor-air humidity senso r is provided with a 2-wire, 42-in. wiring harness with a 2-pin connector. The plug is installed on pins 11 and 12 on J3 of the EconoMi$er+ controller. The pins are labeled ORH and VREF on the EconoMi$er+ controller. See Fig. 22. The orange wire of the harness is connected to pin 11 (ORH). The blue wire of the harness is connected to pin 12 (VREF). The wiring harness should be rout ed fr om the Eco no Mi$er + con tro ller to t he sensor location.

The outdoor enthalpy changeover curve is set at the EconoMi$er+ controller. The factory default is curve “A.” See Fig. 29. See Fig. 30 for Sensor Curve vs. Humidity.
