  • Page 5 This manual is generic in nature and 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 6 Depending on the specific equipment involved, the surface that can accumulate debris can be on the opposite side that is exposed to view when standing in front of the machine. Closely review the machine when operating to see which direction or path that the airflow moves through the machine, and if the air inlet side of the coil is hidden, try to observe the back (hidden) side by looking into the side grilles, using flashlight if necessary.
  • Page 7 stream in the process. It may take several hours to pull down a hot, moist building or structure on initial startup, or anytime the system has been turned off for a long period of time. It is generally best to set the thermostat at a comfortable temperature and let it control the system as needed, rather than turning it on and off.
  • Page 8 The length of the defrost cycle will vary depending upon actual outdoor temperature, humidity levels and amount of accumulated frost. It could range from 1-2 minutes up to but not exceeding 10 minutes. When the defrost cycle terminates, the reversing valve will shift back to heating mode and the outdoor fan will restart.

INSUFFICIENT COOLING OR HEATING In extremely hot or cold weather your system will continue to deliver its normal supply of conditioned air.
  • Page 11 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: 1. Always keep the equipment in peak operating condition with routine scheduled maintenance, especially for the air filters and to assure clean outdoor coil.

  • Page 85: Installing Remote Indoor Temperature/Humidity Sensor(S)

    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 86: Sensor

    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 87 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'.

    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.
