  • Page 4 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 5 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 6 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 7 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.
