Software updates appear on this website under the Support pulldown under Software. Click here to go to the Software page. Below are the steps and warnings for updating the ADH Netcom Waveguide Dehydrator and ASM-1 Smart Manifold. Instructions Navigate to our...
Can I connect more than two dehydrators?
Yes you can connect multiple dehydrators, but this would require the use of an ASM-1 Smart Manifold. In this case, the Manifold is set as the Master to monitor and control the NETCOM’s that are attached to it. This application is used for large systems and can be set...
What is the right dehydrator pressure setting?
The right pressure setting depends on the specification of your waveguide system. You should consult the waveguide manuals or manufacturer for pressure specifications. The waveguide should have both a bleed valve to allow air exchange and a pressure relief valve that...
I occasionally get a high pressure alarm
A high pressure alarm can sometimes occur due to solar gain which is where a portion of the waveguide is exposed to direct sunlight during the heat of the day. The air inside the waveguide expands as it gets hotter causing a rise in pressure. You can confirm this by...
I have a low pressure alarm what is the problem?
There are numerous possibilities for a low pressure alarm, to narrow the search consider your system as three parts: The waveguide, the dehydrator, and the interconnecting tubing. Isolating the dehydrator from the other two parts will determine if the problem is in...
Why do I keep getting the A12 dew point alarm?
The A12 dew point alarm means that the internal humidity sensor is detecting moisture in the canisters. Usually, an alarm may occur for a few seconds and reset itself before it is seen as the unit determines a need to regenerate a canister. At times with high outside...
I am running windows 7 and I cannot communicate with the dehydrator?

Can I regenerate desiccant and if so how do I do it?
Yes, you can regenerate desiccant start by emptying the desiccant into a clean baking dish. Bake desiccant at 350º for two hours, or until silica gel particles turn dark blue, in a conventional oven (do not use a microwave). After the silica gel particles have turned...
How to regenerate the desiccant Passive Dehydrators.
Both the RCD-1 and the RCD-2 passive dehydrators are bottles filled with desiccant, the RCD-1 with no moving parts, uses gas diffusion to dry the waveguide while the RCD-2 uses its one moving part (a check valve), temperature changes and barometric pressure to move...
How can I communicate with my ASM-1 Smart Manifold?
The ASM-1 Smart Manifold can communicate via Ethernet, RS422 and RS232. The Ethernet interface provides the best communications and control of the dehydrator by providing a web based interface. Through this interface, you can monitor the system, change the IP address,...
