Catec Dry***a Dry Cabinet Instruction Manual

CATEC DRY***A Dry Cabinet

General Statement

• On the display panel, the figure in RED means temperature, and the Green refers to humidity. The inside temperature will be 1-3 degrees higher than the ambient temperature.
• The equipment is clarified as per different humidity demand, with model spec as DRY+size+function:
  • DRY***A, 20-60%RH;
  • DRY***B, 10-20%RH;
  • DRY***C, 1-10%RH;
  • DRY***U, 1-5%RH;
  • DRY***D, 1-60%RH (working with N2 or compressed air).
• Additional “E” before ‘A’B’C’U’ D’ means anti-ESD painted.
• Other special functions:
  • H, with heating system for up to 40℃ or 60℃;
  • L, with light tower for temperature / humidity limitation alarm;
  • S, cabinet in stainless steel.

Installation Instruction

1. Place the dry cabinet on a level and strong surface. Turn the adjuster to be balanced.
2. Adjust the height of the shelf as per your storage goods, and the shelf clasp should be put as the following figure.
   • The clasp holes are at regular distance on the slat, to support the shelf on the level surface and to be adjusted up or down by 2.5cm.
3. Leave a space of at least 5cm behind the dry cabinet from the wall for ventilation.
4. Don’t put cabinet in areas where there is direct air flow, such as in front of air conditioner or hot area.
5. Don’t place the cabinet in direct sunlight.
6. Don’t place cabinet in area where there is smoke or stream.
7. Connect the signal cable in series as the number on the plug, then switch on the power supply.
8. The humidity can be set by pressing the ‘up’ and ‘down’ button as per your need.
9. For first application or usage after long-time non-working, you need to run the empty dry cabinet for over 12 hours until the inside humidity moves down to a reasonable lower level as per the model type.
10. The dry cabinet has the memory function to keep the last setting, so don’t need to reset the humidity target again even after power off.
11. Don’t store the materials like fibre board, paper or wood etc., that contains high moisture, in the dry cabinet. This will delay the humidity elimination process.
12. Don’t open the windows too frequently. The opening times shall be well controlled and each opening better to be finished in 15 seconds.
13. If you have a short circuit, you can replace the fuse to restart the dry cabinet. The fuse case is on back of the drying module, as below figure. There are two fuses inside the little case, of which the inside fuse is the working fuse and the out fuse is for spare.

Operation on Control Panel

1. Options of the Control Panel
   1. 2 LED lights for temperature T(℃) in RED and humidity RH(%) in GREEN, 5 buttons for operations；
   2. Button of RUN indicates normal working, ERROR for malfunction. Besides, the ERROR will light up once when connecting USB successfully.

Application Notice

1. Each time of door opening is suggested be as fast as possible, better controlled in 15 seconds, to minimize the humidity rising.
2. Keep power on if possible, to keep the cabinet in good working status.
3. When goods stored inside the cabinet, the cabinet humidity will rise due to the moisture contained in the goods. It may take 1 to 2 days for dehumidifying. For the goods like package paper or cloth that contains heavy humidity, it might take more than 2 days to dehumidify to normal humidity status.
4. The dry cabinet has the memory function, so don’t need to set the humidity again after the last setting, even after power off.
5. The error of humidity value is ±3%RH and the temperature error is about ±2℃.
6. Don’t cover the exhaust vent on the back of the dry cabinet.
7. If been power off over 24 hours, we suggest to move your goods out of the dry cabinet.
8. Please keep the electric lines well connected for static grounding.
9. It’s normal that the surface temperature of the dry cabinet will rise a little when the dry units under moisture exhausting process.
10. If the humidity does not drop down, please switch off the power and restart it again for over 12 hours until the dry cabinet works normal.

SPECIAL INSTRUCTION FOR N2 CABINET (D type)

• Please make sure of the adaptability of power supply before your usage. Normally the power supply is 110V/50Hz, but some areas are different.
• Plugging into the N2 pipe at the inlet of flow-meter and the inlet pressure should be controlled within 0.2~0.7Mpa. The rate of flux can be adjusted within 0~25L/M or 0~60L/M or 0~300L/M, depended on the flow-meter type. The suitable flow rate is about 10-25L/M, if not customized.
• Setting the target humidity during the running period, and better shut off the flow-meter before open the door, then open up the flow-meter again after close the door and adjust the flux for saving N2。
• When the humidity is 0.5%RH higher than the setting humidity (when set within 1~3%RH), the electromagnetic vale will open automatically to restart the air injection. And the valve will open automatically when humidity is 1.5%RH higher than the set target (within 3~10%RH), and 2%RH higher to open if the set value is over 10%RH. You can see the float ball rising up and the cabinet to be filled with N2. If you find the float ball not moving, please check whether any gas leakage happens at the connectors.
• The automatic active time of electromagnetic valve is about half minute.
• The N2 should be clean and does not contain too much impurity such as oil or granulated solid that will damage the electromagnetic valve.
• If you find the cabinet running wrong, please switch the power off firstly. Then restart again after half minute and adjust the setting humidity once again.

Notice points for maintenance

1. Is it plugged in properly? Is the power switched off? Is the fuse broken?
2. Is the humidity setting correct?
3. When operating the dry cabinet for first time or having kept it non-used for long time, did you switch it on and leave it working for at least 12 hours with the empty cabinet?
4. If you want to store materials with high moisture, like paper piles, it may take several days for the dehumidifying process.
5. In the case the dry cabinet fails to work after above checking, please contact us without hesitation.
