North American 240VAC service). Earth ground must always be connected. The APD-D series dehydrators are designed for 120/230VAC use at 50/60Hz. The AC Mains configuration must be 1/N/PE, meaning 3 conductors: 1.) [1] Single phase Line power. (wire color: black or brown) 2.) [N] Neutral (phase return) tied to Earth ground at the local power panel. -

602400011500 Revision C 3 TERMS & DEFINITIONS Dew Point Reduction (Tdr) is the reduction of the dew point temperature Relative Humidity (RH) is the moisture that results from the dehumidification content of the air relative to the maximum process. The larger the Tdr, the more possible moisture content at the current efficient the dehumidification process is. -

It is only used to maintain the unit’s Real- Time Clock (RTC) when the unit is not energized. After replacement, the RTC date and time should be reset. Refer to Picture 6.2.
- Page 17 602400011500 Revision C NOTE: Once the “SetClock.txt” file has been created, it is important to follow the steps below as quickly as possible to ensure a minimum RTC time error exists. 6.3.5 Save the “SetClock.txt” file on the USB device, and then move the USB device to the dehydrator’s front panel USB port.

The unit’s POWER indicator will be illuminated throughout this process. - Page 19 602400011500 Revision C In all cases, the unit’s current operational log file will be written to the USB device. During this operation, the unit’s RUN TIME indicator will flash. If the version of the Operational Software (E_Image.s19) on the upgrade USB device is newer than the unit’s installed software, then it will be updated.
