GENERAL INFORMATION

Air Conditioning System
This Bard air conditioning system is comprised of MEGA-TEC wall-mounted air conditioners matched with an LC6000 supervisory controller or Bard PGD/ PGDx stand-alone display. If only one wall-mounted air conditioner is being used, it can be matched with either the LC6000 supervisory controller or stand-alone controller (see Single Unit Operation on page 4 for information on the PGD and PGDx). If more than one wall mount is installed, the LC6000 controller must be matched with the air conditioning units. The wallmount units are specifically engineered for telecom/ motor control center rooms.

NOTE: The LC6000 supervisory controller or standalone display and MEGA-TEC wall-mount units are designed specifically to work together. The controller or stand-alone display cannot run other brands of systems, nor can other controllers run the MEGA-TEC wall-mount units. They are a complete system, and must be used together.

Wall-Mount Air Conditioner Units
MEGA-TEC units operate on VAC power. If equipped with an economizer, the units will supply 100% of rated cooling airflow in free cooling mode with ability to exhaust the same amount through the unit itself without any additional relief openings in the shelter.
MEGA-TEC units are fully charged with refrigerant and are available with optional electric heat and/or electric reheat dehumidification.
NOTE: 575V models take incoming field power and stepdown secondary to 460V which supplies most components except compressors and electric heat which remain 575V. Reference wiring diagrams for more information.
NOTE: 400V models have only two stages of capacity rather than three and are identical in size. Take note of this when reading this manual.
Single Unit Operation
A PGD or PGDx stand-alone display can be used in place of the LC6000 controller when only one MEGATEC wall-mount air conditioner is being installed. If using a PGD or PGDx stand-alone display instead of the LC6000 controller, the alarm logging and remote communication capabilities of the LC6000 controller will not be available. See PGD manual 2100-734 or PGDx manual 2100-740 for information on installing and setting up a stand-alone display for single unit operation.
General
The equipment covered in this manual is to be installed by trained, experienced service and installation technicians.
The refrigerant system is completely assembled and charged. All internal wiring is complete.
The unit is designed for use with or without duct work. Flanges are provided for attaching the supply and return ducts.
These instructions explain the recommended method to install the air cooled self-contained unit and the electrical wiring connections to the unit.
These instructions and any instructions packaged with any separate equipment required to make up the entire air conditioning system should be carefully read before beginning the installation. Note particularly any tags and/or labels attached to the equipment.
While these instructions are intended as a general recommended guide, they do not supersede any national and/or local codes in any way. Authorities having jurisdiction should be consulted before the installation is made. See Additional Publications for information on codes and standards.

Sizing of systems for proposed installation should be based on heat loss and heat gain calculations made according to methods of Air Conditioning Contractors of America (ACCA). The supply flange should be installed in accordance with the Standards of the National Fire Protection Association for the Installation of Air Conditioning and Ventilating Systems of Other Than Residence Type, NFPA No. 90A, and Residence Type Warm Air Heating and Air Conditioning Systems, NFPA No. 90B. Where local regulations are at a variance with instructions, installer should adhere to local codes.
Shipping Damage
Upon receipt of equipment, the cartons should be checked for external signs of shipping damage. If damage is found, the receiving party must contact the last carrier immediately, preferably in writing, requesting inspection by the carrier's agent.
These units must remain in upright position at all times; do not lay on side. Do not stack units.

SITE PREPARATION

Model Identification
Identify the specific model using the model nomenclature information found in Figure 1 and the model/serial tag found on the unit. See Figure 3 on page 8 for dimensions and critical installation requirements.
New Shelter Installation vs. Retrofit Installation
These installation instructions cover both new shelter installations and retrofit installations. Each installation is unique and may require special accommodations and modifications. Although Bard Manufacturing follows a long-established tradition of manufacturing equipment using industry standard dimensions for building penetration, it is occasionally necessary to move or enlarge supply and return openings when replacing non-standardized equipment in a retrofit application.

Minimum Clearance
To maintain full service access and adequate condenser airflow, side-by-side installations require 28" of clearance between units for access to the economizer (20" of clearance between units without economizers) and proper airflow of the outdoor coil (see Figure 2). Additional clearance may be required to meet local or national codes.
Care should be taken to ensure that the recirculation and obstruction of condenser discharge air does not occur. Recirculation of condenser discharge air can be from either a single unit or multiple units. Any object such as shrubbery, a building or a large object can cause obstructions to the condenser discharge air. Recirculation or reduced airflow caused by obstructions will result in reduced capacity, possible unit pressure safety lockouts and reduced unit service life.
For units with blow through condensers, such as these wall-mount units, it is recommended there be a minimum distance of 10' between the front of the unit and any barrier or 20' between the fronts of two opposing (facing) units.

WALL-MOUNT UNIT MOUNTING

Mounting the Units
! WARNI NG
Unit falling hazard. Use only sufficiently rated mechanical lifting means with proper rigging to raise the unit for mounting. Failure to follow this warning could result in injury or death.

NOTE: It may be best to spot some electrical knockouts (such as those located on the side and rear of the wall-mount unit) before units are mounted and access is unavailable or limited (see Figure 3 to locate pre-punched knockouts).
Heavy duty lifting lug plates are installed on each side of the unit to allow the unit to be lifted and installed on a structure. The plates must be removed and reinstalled in upright position (see Figure 4) for use and can be removed after installation.
The filter access panel handle is shipped with the unit. Attach handle to front of filter access panel using the screws included with the handle as shown in Figure 4.

Two holes for the supply and return air openings must be cut through the wall as shown in Figure 5 on page 10. On wood frame walls, the wall construction must be strong and rigid enough to carry the weight of the unit without transmitting any unit vibration. All walls must be thoroughly inspected to ensure that they are capable of carrying the weight of the installed unit.
In retrofit (unit replacement) installations, the openings cut for the original equipment may not line up exactly with needs of this installation. Modifications may need to be made, such as increasing or decreasing the size of the wall cutouts. The existing bolt placement may not line up in which case the original bolts would need to be removed or cut away.
1. These units are secured by full-length mounting flanges built into the cabinet on each side which secure the unit to the outside wall surface.
2. The unit itself is suitable for 0" clearance, but the supply air duct flange and the first 3' of supply air duct require a minimum of 1/4" clearance to combustible material. See Figure 5 for details on opening sizes.
3. Locate and mark lag bolt locations and location for optional bottom mounting bracket, if desired (see Figure 5).
4. If desired, hook top rain flashing (attached to frontright of supply flange for shipping) under back bend of top.
5. Position unit in opening and secure with fasteners sufficient for the application such as 5/16" lag/ anchor/carriage bolts; use 7/8" diameter flat washers on the lag bolts. It is recommended that a bead of silicone caulking be placed behind the side mounting flanges.
NOTE: For economizer models, mount hoods after unit is installed so as to not block unit flange holes.
6. Secure optional rain flashing to wall and caulk across entire length of top (see Figure 5).
7. For additional mounting rigidity, the return air and supply air frames or collars can be drilled and screwed or welded to the structural wall itself (depending upon wall construction). Be sure to observe required clearance if combustible wall.
8. A plastic drain hose extends from each drain pan at the top of the unit down to the unit base. There are openings in the unit base for the drain hoses to pass through.
NOTE: Ensure hose doesn't kink inside of unit when pulling hose through holes in base. This could prevent proper drainage.

WALL-MOUNT UNIT WIRING
! WARNI NG
Electrical shock hazard. Have a properly trained individual perform these tasks. Failure to do so could result in electric shock or death.

FIGURE 10 VAC Supply Wiring Landing Points

Main Power Wiring
Refer to the unit rating plate or Tables 2A or 2B for wire sizing information and maximum fuse or circuit breaker size. Each outdoor unit is marked with a "Minimum Circuit Ampacity". The field wiring used must be sized to carry that amount of current. Depending on the installed KW of electric heat, there may be two field power circuits required. If this is the case, the unit rating plate will so indicate. All models are suitable only for connection with copper wire. Each unit and/or wiring diagram will be marked "Use Copper Conductors Only". These instructions must be adhered to. Refer to the National Electrical Code (NEC) for complete current carrying capacity data on the various insulation grades of wiring material. All wiring must conform to NEC and all local codes.
The unit rating plate and Tables 2A and 2B list fuse and wire sizes (75°C copper) for all models including the most commonly used heater sizes. Also shown are the number of field power circuits required for the various models with heaters.
The unit rating plate lists a maximum circuit breaker or fuse that is to be used with the equipment. The correct size must be used for proper circuit protection and also to assure that there will be no nuisance tripping due to the momentary high starting current of the compressor motor.
The main unit circuit breaker disconnect access is located on the front panel of the unit.
Route all field power wires in channel under the control panel. See Figure 10 to reference VAC landing points.
Route wires into unit through recommended side entrances (see Figure 11 on page 17). Optional rear entry points are also available (see Figure 12 on page 17).
NOTE: Field wires enter at bottom for line side connection.
When running wires to unit from shelter, be careful to not place wiring and conduit where it will interfere with opening filter access doors.

Unit Control Voltage Wiring

NOTE:

The voltage should be measured at the field power connection point in the unit and while the unit is operating at full load (maximum amperage operating condition.

230/208V Wiring

230/208V 3 phase equipment use dual primary voltage transformers. All equipment leaves the factory wired on 240V tap. It is very important that the correct voltage tap is used. For 208V operation, reconnect from 240V to 208V tap. The acceptable operating voltage range for the 240 and 208V taps are: 240V tap (253 216) and 208 tap (220 197).

460V Wiring

460V 3 phase equipment use triple primary voltage transformers. All equipment leaves the factory wired on 480V tap. It is very important that the correct voltage tap is used. The acceptable operating voltage range for the 480V, 415V and 380V taps are: 480V tap (429 and above), 415 Tap (395 428) and 380 tap (below 395). For 400V N models, use the 415V tap.

NOTE: 575V models take incoming field power and stepdown secondary to 460V which supplies most components except compressors and electric heat which remain 575V. Reference wiring diagrams for more information.

For communication wiring, a 2-wire, 18 gauge colorcoded shielded cable with drain is recommended.

Crankcase Heater Start Up
All units covered in this manual are provided with compressor crankcase heat. This crankcase heater is a band-type heater located around the bottom of the compressor. This heater is controlled by the crankcase heater relay. The heater is only energized when the compressor is not running. Crankcase heat is essential to prevent liquid refrigerant from migrating to the compressor, preventing oil pump out on compressor start up and possible bearing or scroll vane failure due to compressing a liquid. IMPORTANT: The following procedure must be followed at initial start-up and at any time power has been removed for 12 hours or longer. To prevent compressor damage which may result from the presence of liquid refrigerant in the compressor crankcase: 1. Make certain the room thermostat is in the "off"
position (the compressor is not to operate). 2. Apply power by closing the system disconnect
switch. This energizes the compressor heater which evaporates the liquid refrigerant in the crankcase. 3. Allow 4 hours or 60 minutes per pound of refrigerant in the system as noted on the unit rating plate, whichever is greater. 4. After properly elapsed time, the thermostat may be set to operate the compressor. 5. Do not open system disconnect switch except as required for safety while servicing.
Manual 2100-705E Page 18 of 46

PRELIMINARY START UP

Running in Orphan Mode
With the AC breakers turned on, each MEGA-TEC wallmount unit has the capability to run without the LC6000 controller connected--this feature is called orphan mode. This keeps the shelter between 60°F and 77°F (factory default settings) by the use of the factory-installed return air sensor in each wall-mount unit. In orphan mode, the wall unit uses a continuous blower setting to circulate room air into the return air inlet and uses the return air temperature sensor to control room temperature.
The wall-mount unit can be turned on and off with the TEC-EYE hand-held diagnostic tool. When ON is chosen, the wall-mount unit will heat or cool. When set to OFF using the TEC-EYE, the wall-mount unit will not heat, cool or ventilate.
To turn the unit on or off with TEC-EYE:
1. Connect the TEC-EYE diagnostic tool to the control board located in the unit.
2. Press MENU key to go to the Main Menu screen.
3. Press UP or DOWN keys and ENTER key to enter USER password 2000.
4. Press UP or DOWN keys to scroll to On/Off; press ENTER key.
5. Press UP or DOWN keys to change value from ON to OFF or from OFF to ON.
6. Press ESCAPE key several times to return to Main Menu screen.
To verify or change the wall-mount unit cooling and heating setpoints in orphan mode:
1. Connect the TEC-EYE diagnostic tool to the control board located in the unit.
2. From the Status screen, press UP or DOWN key until Quick Menu displays Setpoints (SET) icon. Press ENTER key.
3. Press ENTER key to scroll to the selected choice (see Figure 13).
4. Press UP or DOWN key on desired value until value displays correctly.
5. Press ENTER key to save and scroll to next parameter.
6. Press ESCAPE key until Main Menu screen is displayed.

FIGURE 13 Cooling and Heating Setpoints
During installation, the ability to run in orphan mode allows deactivation of one of the existing, older wallmount units, while keeping the shelter cool with the other unit still operating. Once the first of the Bard MEGA-TEC wall-mount units is installed, orphan mode can be enabled early in the installation--keeping the climate inside the shelter stable and the installers comfortable while the remainder of the older equipment is removed and the remaining Bard MEGA-TEC wallmount units and LC6000 controller are installed. Additionally, should any or all of the MEGA-TEC wallmount units lose communication with the LC6000 controller (such as during maintenance), they will continue to serve the shelter's needs until a repair can be made.

Electrical shock hazard. Disconnect VAC power supplies before servicing. Failure to do so could result in electric shock or death.
IMPORTANT: When working with circuit board components, Bard recommends the use of an anti-static wrist strap to prevent static electricity shorts to electronic controls.
LC6000 Controller
The LC6000 controller is part of this air conditioning system. It is used to control up to fourteen (14) wall-mount air conditioners from one controller. The microprocessor control provides an easy-to-read interface with large LCD graphical display. It provides control for redundancy for the structure and equal wear on all units.
Conduit is recommended for all wiring. Route communication wiring and power supply wiring in their own separate conduits.
The LC6000 controller is not weatherproof and is intended for use in a weathertight structure.

Mounting the LC6000 Controller
The dimensions of the LC controller are 16" x 12" x 6".
Because the LC6000 controller utilizes a remote temperature sensor as opposed to one located in the controller box, the controller itself can be installed in any indoor location that is suitable, preferably at eye level. Four (4) mounting holes are provided for mounting to the wall and holes for conduit connections are provided in the base, sides and top of the controller.
The LC6000 controller includes four fused power supply terminals in the terminal block. Before connecting wires to the terminal block, confirm that the fuse in each of the four fuse holders is in the proper position (active) as shown in Figure 15.

Installing Remote Indoor Temperature/Humidity Sensor(s)
One remote indoor temperature/humidity sensor and 35' of 18 gauge 5-conductor shielded cable is included with the controller. This sensor must be installed for proper operation. Mount the temperature/humidity sensor in a location least likely to be affected by open doors, rack-mounted fans, radiant heat sources, etc. Locating the sensor between both return grilles is often the best location, but every installation is unique. Location height should be approximately 60" above the floor. The sensor is best mounted on a 2" x 4" junction box and it is recommended that the cable be in conduit. Use shielded cable to connect to controller. The maximum cable length to connect the temperature/humidity sensor to the LC6000 is 98'.

For proper operation, the remote indoor temperature/humidity sensor (and any additional sensors) must be configured properly with the controller as shown in Step 2 on page 22. An additional remote indoor temperatureonly sensor can be purchased and installed in Zone 1. If the site in which the LC6000 controller will be used has more than one zone (maximum three zones per LC6000), additional remote temperature/humidity sensors (one per zone) will need to be purchased and installed in the additional zones. All installed sensors must be enabled in the controller menu (see Configure Sensors beginning on page 36).
FIGURE 17 Additional Remote Indoor Temperature and Temperature/Humidity Sensor Installation
One additional temperature sensor can be added to Zone 1 and additional temperature/humidity sensors may be added to Zones 2 and 3 (one per zone).

Communication Wiring
Connect the field-supplied communication wiring from the wall-mount units to the controller in the manner shown in Figures 20, 21 or 22. The daisy chain does not need to follow the addressing order. The communication wire should be 2-wire, 18 gauge shielded cable with drain. Any color can be used. Be sure to match "+" and "-" symbols on controller terminal blocks to prewired unit control terminal block (see Figures 24 and 25 on pages 29 and 30). Attach communication wire filters as shown in Figures 20, 21 or 22. Do not run communication wiring in same conduit as supply wiring. Route communication wiring and power supply wiring in their own separate conduits.

Setpoints
The LC6000 setpoints will determine the cooling and heating setpoints when communicating with the wallmount units. The unit cooling and heating setpoints will determine the cooling and heating setpoints when in orphan mode. It is important to note that once the wall-mount unit establishes communication with the LC6000, the setpoints from the LC will override the wall-mount unit setpoints. If a unit returns to orphan mode after communicating with LC, it will operate with last communicated setpoints from the LC.
If at any time the unit(s) loses communication with the LC6000 controller, the unit(s) will go into orphan mode.

TABLE 8 LC6000 Status Messages

Message

Description

The LC6000 is ready and functioning properly.

The LC6000 is being turned off by the Off by BMS Building Management System through
Modbus TCP/IP.

Off by Keyboard

The LC6000 is turned off using the (D. On/Off) Menu on the PGD. All communicating units will be inactive.

Comfort Mode

The LC6000 is set to Comfort Mode. This mode is used to temporarily override heating/cooling setpoints and maintain a default temperature of 72°F for 60 minutes.

Emergency Cooling

A high temperature has been sensed in one or more zones. All available units in that zone are sent a command for emergency cooling. (Refer to unit manual for emergency cooling sequence.)

Emergency Vent

Input signal from an external device at terminal DI2 (e.g., hydrogen detector). Units that are equipped with a ventilation option and configured will open the dampers at 100% with the blower at full speed.

A/C Circuit Information
MEGA-TEC Series wall-mounted air conditioners have two separate refrigeration circuits: Circuit 1 is the two stage system located on the left side of the unit and circuit 2 is the single stage system on the right side (see Figure 49).
NOTE: 400V models have only two stages of capacity rather than three and are identical in size. Take note of this when reading this manual.
For more information on the MEGA-TEC dual A/C circuits, see the latest version of Service Instructions 2100-671.

Remote Indoor Temperature/Humidity Sensor Orientation
Current versions of the remote indoor temperature/ humidity sensor need to be installed with the shielded cable wires entering the bottom of the back of the sensor to connect to the sensor terminals (see Figure 50). Earlier versions of this sensor were installed so that the sensor wires entered through the top of the back of the sensor (see Figure 51). The orientation of the sensor affects the position of the DP1/DP2 jumpers. Depending on how the sensor is installed, be sure to confirm that the jumpers are in the proper position for the 0-1 V setting as shown in the figures below.
This applies to all indoor temperature/humidity sensors connected to the LC controller. See illustration mounted inside of sensor cover for further detail on jumper position.
