Page 15: Leak Detection
Doc #: 10000036989 Ver A If the purge is left to the dehydrator's normal operation, the process may take days, weeks, or longer depending on the dehydrator's installed options, system size, moisture levels, and other variables. Humidity alarms may occur until the moisture is purged from the system. Use the following steps to purge the system.
Page 16: Alarm Indicator
Doc #: 10000036989 Ver A To control the cylinder regeneration, the dehydrator employs a micro-processor. First, the drying cylinder is heated to convert the moisture absorbed by the desiccant into steam. After heating for 1.5 hours, the dehydrator purges for 5 minutes to release the vapor. This evaporation and purging process is repeated once more.
Page 17 Doc #: 10000036989 Ver A 4.3 Control Buttons On the front panel, you will find four control buttons: +Add/P, -Dec/Q, Set, and Leak Detection. 4.3.1 +Add/P Button The "+Add/P" button is utilized to increase the value in the pressure (H XX and L XX) and unit ID (IXXX) setting interface, or switch the value in the Push Button Tone (on/off) setting interface.

Page 19 Doc #: 10000036989 Ver A 4.4.5 Excess-Run Alarm The dehydrator will show an alarm if it runs continuously for 30 minutes without reaching the high-pressure limit. A leak is the main cause of this alarm. In this situation, the dehydrator will not stop until it reaches the high-pressure limit or runs continuously for 60 minutes.
Page 20 Doc #: 10000036989 Ver A 4.5.3 Number of Inflating: cXXX At the “P XX” interface, press the “-Ded/Q” button four times. The display window shows “c XXX” where “XXX” represents the total number of inflations by the dehydrator. The maximum value is 255 and the counter resets after 255.
Page 21: Maintenance And Troubleshooting
Doc #: 10000036989 Ver A 4.5.6 Regenerating State: C XX At the “P XX” interface, press the “-Ded/Q” button seven times. The dehydrator’s regenerating state code will be displayed as “C XX”. You can find the description of the dehydrator regenerating state to each code in the table below.
Page 22 Doc #: 10000036989 Ver A Attention: Make sure the power is turned off before starting this cleaning process. Gently open the panel. Be careful not to harm the cable connection when opening the dehydrator for inspection or cleaning. Step 1: Open the top panel of the dehydrator. Locate the white air inlet. Step 2: While pressing the blue ring backward, gently pull the white air inlet filter out of the fitting.
Page 23 Doc #: 10000036989 Ver A Step 4: Ensure that the filter is securely inserted into the fitting until it firmly locks into the position. Reinstall the panel. 5.1.2 8,000 Hours Maintenance To ensure the continuous and efficient operation of the dehydrator and to prevent dust from blocking the solenoid valve, it is recommended to perform the maintenance of the solenoid valves after every 8,000 hours of service time.
Page 24: Troubleshooting
Doc #: 10000036989 Ver A Step 4: Remove the dust from the plunger and the valve body with high-pressure air. If there is rust, wipe it with alcohol. Clear all 3 valves. Step 5: Install the solenoid valve back in place. Connect the tube according to the signage stickers. Step 6: Check the installation position of the tubes again, do not misconnect.
