  • Page 2: Safety Instructions

    Introduction The H300P is a simple to use, versatile temperature / humidity chamber. Its super compact design allows it to be placed on any table top. Its solid state design means low noise and low power operation. The solid state design also removes the need for user maintenance other that refilling water and desiccant.

  • Page 3: Operation Safety Notices

    Improper modifications to these setup values can result in erratic performance and unreliable operation. Do not attempt to modify the setup values, unless you thoroughly understand what you are doing. If there is any doubt, please contact the Folyon Technologies before proceeding.

  • Page 4: Installation Location

    Make sure the unplug the chamber before filling or emptying water. Setup Before the H300P can be used, it needs to have sufficient water and desiccant for proper operation. The chamber comes from the factory with the desiccant preloaded, but without any water.

  • Page 5: Desiccant Filling And Replacement

    The desiccant is the drying agent of the H300P chamber. The recommended desiccant is the Regular Drierite 8 mesh desiccant. The H300P comes preloaded with fresh desiccant. When the desiccant is fresh, it is blue. As the desiccant gets used up, it turns red. When the desiccant is all red, it should be replaced.
  • Page 6 Figure 2: Desiccant Reservoir Pulled From H300P • Unscrew the reservoir plug and remove the spring, dust filter and metal mesh. • Remove the used desiccant. The used desiccant can be regenerated by heating it above 395°F (200°C) for one to two hours.

  • Page 7: Principles Of Operation

    Principles of Operation The H300P temperature humidity chamber controls the humidity by circulating the air inside the chamber through the desiccant to decrease humidity, or through a water vapor chamber to increase humidity. Air entering the chamber from the desiccant is very close to 0%RH. Air entering the chamber from the vapor chamber is close to 100%RH.

    However, when trying to achieve high humidity (above 75%RH) at high temperatures (above 90°F, 32°C), you may have to wait for the water in the reservoir to heat up. Note that the water in the reservoir will warm up whenever the H300P is ON, even if the CONT switch is turned to OFF.
  • Page 9 Watlow PM PLUS Controllers The H300P unit uses the Watlow PM PLUS controllers. The controller User’s Manual has been provided with the H300P chamber. In general you should not need to reference this manual, unless you are setting up a profile.
