Step 2 — Plan for Sequence of Unit Installation
The support method used for this unit will dictate different sequences for the steps of unit installation. For example, on curb--mounted units, some accessories must be installed on the unit before the unit is placed on the curb. Review the following for recommended sequences for installation steps.
Curb--mounted installation —
Install curb Install field--fabricated ductwork inside curb Install accessory thru--base service connection package
(affects curb and unit) (refer to accessory installation instructions for details)
Prepare bottom condensate drain connection to suit planned condensate line routing (refer to Step 9 for details)
Rig and place unit Install outdoor air hood Install condensate line trap and piping Make electrical connections Install other accessories
Pad--mounted installation —
Prepare pad and unit supports Check and tighten the bottom condensate drain
connection plug Rig and place unit Convert unit to side duct connection arrangement Install field--fabricated ductwork at unit duct openings Install outdoor air hood Install condensate line trap and piping Make electrical connections Install other accessories
Frame--mounted installation —
Frame--mounted applications generally follow the sequence for a curb installation. Adapt as required to suit specific installation plan.
Step 3 — Inspect unit
Inspect unit for transportation damage. File any claim with transportation agency.
Confirm before installation of unit that voltage, amperage and circuit protection requirements listed on unit data plate agree with power supply provided.
Step 4 — Provide Unit Support
Roof Curb Mount —
Accessory roof curb details and dimensions are shown in Fig. 4. Assemble and install accessory roof curb in accordance with instructions shipped with the curb.
NOTE: 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. 4. Improperly applied gasket can also result in air leaks and poor unit performance.
Curb should be level. This is necessary for unit drain to function properly. Unit leveling tolerances are show in Fig. 5. Refer to Accessory Roof Curb Installation Instructions for additional information as required.
Install insulation, cant strips, roofing felt, and counter flashing as shown. Ductwork must be attached to curb and
not to the unit. The accessory thru--the--base power package must be installed before the unit is set on the roof curb.
If electric and control wiring is to be routed through the basepan, attach the accessory thru--the--base service connections to the basepan in accordance with the accessory installation instructions.
Slab Mount (Horizontal Units Only) —
Provide a level concrete slab that extends a minimum of 6 in. (150 mm) beyond unit cabinet. Install a gravel apron in front of condenser coil air inlet to prevent grass and foliage from obstructing airflow.
NOTE: Horizontal units may be installed on a roof curb if required.
Alternate Unit Support (In Lieu of Curb or Slab Mount) —
A non--combustible sleeper 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. (102 mm x 102 mm) pads on each side.

Fig. 19 -- Weatherproof Cover Installation
Non--powered type: This type requires the field
installation of a general--purpose 125--volt 15--A circuit powered from a source elsewhere in the building. Observe national and local codes when selecting wire size, fuse or breaker requirements and disconnect switch size and location. Route 125--v power supply conductors into the bottom of the utility box containing the duplex receptacle.
Unit--powered type: A unit--mounted transformer is factory--installed to stepdown the main power supply voltage to the unit to 115--v at the duplex receptacle. This option also includes a manual switch with fuse, located in a utility box and mounted on a bracket behind the convenience outlet; access is through the unit’s control box access panel. See Fig. 18.
The primary leads to the convenience outlet transformer are not factory--connected. Selection of primary power source is a customer--option. If local codes permit, the transformer primary leads can be connected at the line--side terminals on the unit--mounted non--fused disconnect or HACR breaker switch; this will provide service power to the unit when the unit disconnect switch or HACR switch is open. Other connection methods will result in the convenience outlet circuit being de--energized when the unit disconnect or HACR switch is open. See Fig. 20.
Duty Cycle: the unit--powered convenience outlet has a duty cycle limitation. The transformer is intended to provide power on an intermittent basis for service tools, lamps, etc; it is not intended to provide 15--amps loading for continuous duty loads (such as electric heaters for overnight use). Observe a 50% limit on circuit loading above 8--amps (i.e., limit loads exceeding 8--amps to 30 minutes of operation every hour).

Voltage to compressor terminals during operation must be within voltage range indicated on unit nameplate. See Table 5. On 3--phase units, voltages between phases must be balanced within 2% and the current within 10%. Use the formula shown in the legend for Table 5, Note 2 (see page 39) to determine the percent of voltage imbalance. Operation on improper line voltage or excessive phase imbalance constitutes abuse and may cause damage to electrical components. Such operation would invalidate any applicable Bryant warranty.

Thermostat —
Install a Bryant--approved accessory thermostat according to installation instructions included with the accessory. For complete economizer function, select a two--stage cooling thermostat. Locate the thermostat accessory on a solid wall in the conditioned space to sense average temperature in accordance with the thermostat installation instructions.
If the thermostat contains a logic circuit requiring 24--v power, use a thermostat cable or equivalent single leads of different colors with minimum of seven leads. If the thermostat does not require a 24--v source (no “C” connection required), use a thermostat cable or equivalent with minimum of six leads. Check the thermostat installation instructions for additional features which might require additional conductors in the cable.
For wire runs up to 50 ft. (15 m), use no. 18 AWG (American Wire Gage) insulated wire (35_C minimum). For50to75ft.(15to23m),useno.16AWGinsulated wire (35_C minimum). For over 75 ft. (23 m), use no. 14 AWG insulated wire (35_C minimum). All wire sizes larger than no. 18 AWG cannot be directly connected to the thermostat and will require a junction box and splice at the thermostat.
Unit without thru--base connection kit —
Pass the thermostat control wires through the hole provided in the end panel (see item “D” in the view labeled “LEFT” in Fig. 1 & 2); then feed the wires through the raceway built into the corner post to the control box. Pull the wires over to the terminal strip on the upper--left corner of the Central Ternimal Board (CTB). See Fig. 22.

Single Point Boxes and Supplementary Fuses — When the unit MOCP device value exceeds 60--A, unit--mounted supplementary fuses are required for each heater circuit. These fuses are included in accessory Single Point Boxes, with power distribution and fuse blocks. The single point box will be installed directly under the unit control box, just to the left of the partition separating the indoor section (with electric heaters) from the outdoor section. The Single Point Box has a hinged access cover. See Fig. 27. The Single Point Box also includes a set of
558J***D
power taps and pigtails to complete the wiring between the Single Point Box and the unit’s main control box terminals. Refer to the accessory heater and Single Point Box installation instructions for details on tap connections.
All fuses on 558J***D units are 60--A. (Note that all heaters are qualified for use with a 60--A fuse, regardless of actual heater ampacity, so only 60--A fuses are necessary.)
Single Point Boxes without Fuses — Unit heater applications not requiring supplemental fuses require a special Single Point Box without any fuses. The accessory Single Point Boxes contain a set of power taps and pigtails to complete the wiring between the Single Point Box and the unit’s main control box terminals. Refer to accessory heater and Single Point Box installation instructions for details on tap connections.

RTU--MP control system
The RTU--MP controller, see Fig. 29, provides expanded stand--alone operation of the HVAC system plus connection and control through communication with several Building Automation Systems (BAS) through popular third--party network systems. The available network systems are BACnet MP/TP, Modbus and Johnson J2. Communication with LonWorks is also possible by adding an accessory interface card to the RTU--MP. Selection of the communication protocol and baud rate are made at on--board DIP switches.
The RTU--MP control is factory--mounted in the 558J***D unit’s main control box, to the left of the CTB. See Fig. 30. Factory wiring is completed through harnesses connected to the CTB. Field connections for RTU--MP sensors will be made at the Phoenix connectors on the RTU--MP board. The factory--installed RTU--MP control includes the supply--air temperature (SAT) sensor. The outdoor air temperature (OAT) sensor is included in the FIOP/accessory EconoMi$ert2 package.
Refer to Table 3, RTU--MP Controller Inputs and Outputs for locations of all connections to the RTU--MP board.

558J***D
The RTU--MP controller requires the use of a Bryant space sensor. A standard thermostat cannot be used with the RTU--MP system.
Supply Air Temperature (SAT) Sensor -- On FIOP--equipped 558J***D unit, the unit is supplied with a supply--air temperature (SAT) sensor (33ZCSENSAT). This sensor is a tubular probe type, approx 6--inches (12.7 mm) in length. It is a nominal 10--k ohm thermistor.
The SAT is factory--wired. The SAT probe is wire--tied to the supply--air opening (on the horizontal opening end) in its shipping position. Remove the sensor for installation. Re--position the sensor in the flange of the supply--air opening or in the supply air duct (as required by local codes). Drill or punch a 1/2--in. hole in the flange or duct. Use two field--supplied, self--drilling screws to secure the sensor probe in a horizontal orientation. See Fig. 32.

Outdoor Air Temperature (OAT) Sensor -- The OAT is factory--mounted in the EconoMi$er2 (FIOP or accessory). It is a nominal 10k ohm thermistor attached to an eyelet mounting ring.
EconoMi$er2 -- The RTU--MP control is used with EconoMi$er2 (option or accessory) for outdoor air management. The damper position is controlled directly by the RTU--MP control; EconoMi$er2 has no internal logic device.
Outdoor air management functions can be enhanced with field--installation of these accessory control devices:

Field Connections -- Field connections for accessory sensors and input devices are made the RTU--MP, at plugs J1, J2, J4, J5, J11 and J20. All field control wiring that connects to the RTU--MP must be routed through the
558J***D
raceway built into the corner post as shown in Fig. 23. The raceway provides the UL required clearance between high-- and low--voltage wiring. Pass the control wires through the hole provided in the corner post, then feed the wires thorough the raceway to the RTU--MP. Connect to the wires to the removable Phoenix connectors and then reconnect the connectors to the board.
Space Temperature (SPT) Sensors
A field--supplied Bryant space temperature sensor is required with the RTU--MP to monitor space temperature. There are 3 sensors available for this application:
S 33ZCT55SPT, space temperature sensor with override
button
S 33ZCT56SPT, space temperature sensor with override
button and setpoint adjustment
S 33ZCT59SPT, space temperature sensor with LCD
(liquid crystal display) screen, override button, and setpoint adjustment
Use 20 gauge wire to connect the sensor to the controller. The wire is suitable for distances of up to 500 ft. Use a three--conductor shielded cable for the sensor and setpoint adjustment connections. If the setpoint adjustment (slidebar) is not required, then an unshielded, 18 or 20 gauge, two--conductor, twisted pair cable may be used.

(33ZCSENCO2) -- Typical Wiring Diagram
To accurately monitor the quality of the air in the conditioned air space, locate the sensor near a return--air grille (if present) so it senses the concentration of CO leaving the space. The sensor should be mounted in a location to avoid direct breath contact.
Do not mount the IAQ sensor in drafty areas such as near supply ducts, open windows, fans, or over heat sources. Allow at least 3 ft (0.9 m) between the sensor and any corner. Avoid mounting the sensor where it is influenced by the supply air; the sensor gives inaccurate readings if the supply air is blown directly onto the sensor or if the supply air does not have a chance to mix with the room air before it is drawn into the return airstream.
Wiring the Indoor Air Quality Sensor —
For each sensor, use two 2--conductor 18 AWG (American Wire Gage) twisted--pair cables (unshielded) to connect the separate isolated 24 vac power source to the sensor and to connect the sensor to the RTU--MP control board terminals.

Communication Wiring -- Protocols
General
Protocols are the communication languages spoken by control devices. The main purpose of a protocol is to communicate information in the most efficient method possible. Different protocols exist to provide different kinds of information for different applications. In the BAS application, many different protocols are used, depending on manufacturer. Protocols do not change the function of a controller; just make the front end user different.
The RTU--MP can be set to communicate on four different protocols: BACnet, Modbus, N2, and LonWorks. Switch 3 (SW3) on the board is used to set protocol and baud rate. Switches 1 and 2 (SW1 and SW2) are used to set the board’s network address. See Fig. 45 for the switch setting per protocol. The 3rd party connection to the RTU--MP is through plug J19.
NOTE: Power must be cycled after changing the SW1--3 switch settings.
Contact your Bryant applications engineer for more detailed information on protocols, 3rd party wiring, and networking.

Controller
The controller (see Fig. 47) includes a controller housing,
SMOKE DETECTORS
a printed circuit board, and a clear plastic cover. The controller can be connected to one or two compatible duct
Smoke detectors are available as factory--installed options on 558J***D models. Smoke detectors may be specified for Supply Air only or for Return Air without or with economizer or in combination of Supply Air and Return Air. Return Air smoke detectors are arranged for vertical return configurations only. All components necessary for operation are factory--provided and mounted. The unit is factory--configured for immediate smoke detector shutdown operation; additional wiring or modifications to unit terminal board may be necessary to complete the unit and smoke detector configuration to meet project requirements.
Units equipped with factory--optional Return Air smoke detectors require a relocation of the sensor module at unit installation. See “Completing Installation of Return Air
Smoke Sensor:” on page 29 for details.
System
The smoke detector system consists of a four--wire controller and one or two sensors. Its primary function is
smoke sensors. The clear plastic cover is secured to the housing with a single captive screw for easy access to the wiring terminals. The controller has three LEDs (for Power, Trouble and Alarm) and a manual test/reset button (on the cover face).
Sensor
The sensor (see Fig. 48) includes a plastic housing, a printed circuit board, a clear plastic cover, a sampling tube inlet and an exhaust tube. The sampling tube (when used) and exhaust tube are attached during installation. The sampling tube varies in length depending on the size of the rooftop unit. The clear plastic cover permits visual inspections without having to disassemble the sensor. The cover attaches to the sensor housing using four captive screws and forms an airtight chamber around the sensing electronics. Each sensor includes a harness with an RJ45 terminal for connecting to the controller. Each sensor has four LEDs (for Power, Trouble, Alarm and Dirty) and a manual test/reset button (on the left--side of the housing).

Air is introduced to the duct smoke detector sensor’s sensing chamber through a sampling tube that extends into the HVAC duct and is directed back into the ventilation system through a (shorter) exhaust tube. The difference in air pressure between the two tubes pulls the sampled air through the sensing chamber. When a sufficient amount of smoke is detected in the sensing chamber, the sensor signals an alarm state and the controller automatically takes the appropriate action to shut down fans and blowers, change over air handling systems, notify the fire alarm control panel, etc.
The sensor uses a process called differential sensing to prevent gradual environmental changes from triggering false alarms. A rapid change in environmental conditions, such as smoke from a fire, causes the sensor to signal an alarm state but dust and debris accumulated over time does not.
For installations using two sensors, the duct smoke detector does not differentiate which sensor signals an alarm or trouble condition.

Supply Air — The Supply Air smoke detector sensor is located to the left of the unit’s indoor (supply) fan. See Fig. 49. Access is through the fan access panel. There is no sampling tube used at this location. The sampling tube inlet extends through the side plate of the fan housing (into a high pressure area). The controller is located on a bracket to the right of the return filter, accessed through the lift--off filter panel.

Return Air with Economizer — The sampling tube is inserted through the side plates of the economizer housing, placing it across the return air opening on the unit basepan. See Fig. 51. The holes in the sampling tube face downward, into the return air stream. The sampling tube is connected via tubing to the return air sensor that is mounted on a bracket high on the partition between return filter and controller location. (This sensor is shipped in a flat--mounting location. Installation requires that this sensor be relocated to its operating location and the tubing to the sampling tube be connected. See installation steps below.)
Completing Installation of Return Air Smoke Sensor:
1. Unscrew the two screws holding the Return Air Sensor detector plate. See Fig. 52. Save the screws.

Step 11 — Perfect Humidityt –
Dehumidification System —
The Perfect Humidity dehumidification system requires a field--supplied and --installed space relative humidity control device such as Bryant’s Edge Programmable Thermostat with isolated contact set for dehumidification control.
To connect the Edge Programmable Thermidistat (T6--PRH01--A):
1. Route the Edge Programmable Thermostat multi-­conductor cable (field--supplied) through the hole provided in the unit corner post.
2. Feed wires through the raceway build into the corner post (see Fig. 23) to the 24--v barrier located on the left side of the control box. The raceway provides the UL--required clearance between high--voltage and low--voltage wiring.
3. The Edge Programmable Thermostat has dry contacts
558J***D
at terminals D1 and D2 for dehumidification operation (see Fig. 55). The dry contacts must be wired between CTB terminal R and the PINK lead to the LTLO switch with field--supplied wire nuts. Refer to the installation instructions included with the Bryant Edge Programmable Thermidistat device for more information.

1. In compliance with NEC requirements for multimotor and combination load 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 phase imbalance in supply voltage is greater than 2%. Use the following formula to de­termine the percentage of voltage imbalance.
% Voltage Imbalance = 100 x
max voltage deviation from average voltage
average voltage
Example: Supply voltage is 230-3-60
AB = 224 v BC = 231 v AC = 226 v
Average Voltage =
(224 + 231 + 226)
= 227
3
=
681
3
Determine maximum deviation from average voltage. (AB) 227 – 224 = 3 v (BC) 231 – 227 = 4 v (AC) 227 – 226 = 1 v Maximum deviation is 4 v. Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x
= 1.76%

227
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.
