Page 4 General Information The User's Application Guide covers a wide range of heating and cooling products manufactured by Bard Manufacturing Company. It is intended to be a general guide for care and operation of typical systems and covers the most important features you should be aware of and are responsible for as the user of the equipment.
Page 5 Heat Pumps and Heat Pumps and Heat Pumps The User's Application Guide and Technical Product Overview covers the following topics: • Documentation provided by Bard for proper use of your new product. • Unit installation guidelines. • Routine unit maintenance.
Page 6 Unit Literature Assembly – Documentation Provided with Your Unit Bard products are shipped with documentation that when used by a technician with cooling and heating knowledge, can ensure that your product is installed safely, performs optimally and achieves the longest life cycle possible.
Page 7 Unit Installation Installation plays a key part in unit functionality, performance and safety. Product securing and placement, duct design and supply/return location, electrical routing and condensate and defrost drainage all play key roles in making sure a unit will perform per the design specifications. WALL MOUNT Products –...
Page 8 WALL MOUNT Products – Clearances for Indoor Supply and Return Airflow The Bard unit should be placed in an area where the supply (leaving conditioned air) and return (unit air intake) air paths will be unrestricted. Avoid placing objects in the structure within 24" of the return (unit air intake) grille.

Page 10 It is recommended to allow 15' (457.2 cm) in front of unit louver for proper condenser airflow. Always use common sense when installing products, follow unit clearances given in the installation instructions and contact local Bard distributors when additional knowledge is needed regarding unit clearances for proper unit functionality.
Page 11 I-TEC and Q-TEC Products – Clearances for Indoor Supply and Return Airflow The Bard unit should be placed in an area where the supply (leaving conditioned air) and return (unit air intake) air paths will be unrestricted. Avoid placing objects inside the room within 24" of the return (unit air intake) louvers or grille.
Page 12 This is collected in an evaporator pan and needs to be drained to an external drainage system. Your new Bard product includes provisions to allow condensate water to exit the unit and fittings will need to be field supplied to connect the unit drain to the building.
Page 13 Failure to do so may result in death, injury or product damage. A proper power supply to your new Bard unit is very important. Be sure to verify the following with a multi-meter or other power measuring device before applying power to your Bard product.
Page 14 Outdoor Unit Wall Mount Room Air Filters Wall mount filters are normally accessed from the outside of the building. Bard does offer a return air grille with a filter frame built-in for indoor filter access. The return air filter grille is not acceptable as the only source of filtration if vent options are installed in the wall mount unit.
Page 15 WALL MOUNT Products – Filters and Filter Servicing The built-in filter tray and room air filters in the wall mount are located in the middle of the cabinet below the indoor blowers. Units with vent options will have a washable screen behind the vent intake panel. Filter Door: The unit room air filter is located behind Vent Intake...
Page 16 The washable filters are used to remove dirt and dust from outdoor air that is entering the vent area. If at any time these filters are damaged, they must be replaced with Bard-approved filters. I-TEC Filter Locations:...
Page 17 Q-TEC Indoor Products – Filters and Filter Servicing The Q-TEC indoor air conditioners and heat pumps have two room air filters that must be replaced when servicing the unit. Filters play an important part in proper unit operation and prevent dirt and dust buildup inside the Q-TEC and the room the unit is installed in.
Page 18 Coils should be ordered with a corrosion protective coating. Contact Bard for coating options. 3. Frequent cleaning and waxing of the cabinet using a good automobile polish will help extend its original appearance and protect painted surfaces.
Page 19 All Products – Condenser Airflow W**A, W**H, T**H, T**S, W*RV Wall Mount Units: These units are called “blow through condenser airflow” units because they draw cool outdoor air from the sides and blow the warm condenser air exiting the coil through the front grille. C**H Wall Mount Units: These units are called “draw through condenser airflow”...
Page 20 Unit Operation Air-to-Air Cooling Products (Air Conditioners) The cooling mode operates similar to a refrigerator, removing heat from inside the conditioned space and rejecting it outside of the space being controlled. There are three main parts of the system: 1. The evaporator (indoor) coil where cold refrigerant absorbs heat from the air, which circulates from the conditioned space through the machine and is returned to the space at a lower temperature and with some of the humidity (moisture) removed.
Page 21 terminates, the reversing valve will shift back to heating mode and the outdoor fan will restart. There is typically a large puff of steam emitted as the fan restarts. When the heat pump shifts from cool to heating mode, from heating to cooling mode and especially during defrost cycles, there will be a pressure transfer sound heard as the reversing valve redirects the flow of refrigerant.
Page 22 Ventilation Options (Air-to-Air or Water-to-Air Systems) All Bard systems are available with factory-installed vent options. Most units can have ventilation field installed after unit installation.
Page 23 Helpful Hints and Good Operating Practices The following information will help you enjoy the full comfort and benefits of your Bard cooling and heating system, maximize the performance and efficiency and help extend the life of your system.

Page 114 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.
Page 115 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 temperature- only 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.
Page 116 Installing Optional Outdoor Temperature/Humidity Sensor One optional outdoor temperature/humidity sensor (8301-090) can be installed. Follow the manufacturer's mounting instructions. Use 18 gauge 5-conductor shielded cable to connect to controller. The maximum cable length to connect the temperature/humidity sensor to the LC6000 is 98'. FIGURE 16 Remote Outdoor Temperature/Humidity Sensor Installation Connect wires from the 18 gauge shielded cable to terminals #65, #66, #67, #70 and #71.

There are factory-installed jumpers across terminals #6 and #7 (emergency off), #8 and #9 (emergency ventilation) and #10 and #11 (generator run). Remove the factory-installed jumpers before making the connections. FIGURE 17 LC6000-200 Series Connection for Emergency Off, Emergency Ventilation and Generator Run (If Applicable) Generator Run*...
Page 118 Communication Wiring Connect the communication wiring from the wall-mount units to the controller in the manner shown in Figures 18, 19 or 20. The daisy chain does not need to follow the addressing order. The communication wire should be 2-wire, 18 gauge shielded cable with drain.

Page 123 Supply Wiring The LC6000 controller is powered by 120, 208 or 240 volts from the shelter. Field-supplied supply wiring should be minimum 16 gauge, maximum 14 gauge (see Figure 24). A reliable earth ground must be connected in addition to any grounding from conduit. Grounding bolts and nuts are included with the controller for this purpose; a 2 hole grounding lug must be field supplied.
