Hi, I’m Jay, and this is the Aprilaire 350 and 360 maintenance kit. It should be replaced every five years. Included in the kit is a water panel, scale control insert, water distribution tray, feed tube, feed nozzle, and a strainer screen.

Replacement is easy. Here’s how.
Be sure to turn the power off before performing any maintenance.
Before performing this service, it is necessary to shut off the water. Find the saddle valve, turn it clockwise until it stops.

Alright, let’s slide the water panel into the scale control insert. You’ll notice there are slots cut into it; they line up with the little tabs here. It snaps into place. Now we’re going to put the top on it, which also snaps into place. And the assembly is now ready to be installed inside of your humidifier.

Slide the brass nut onto the feed tube. Be sure to put it on the end containing the orifice. Now we’re going to slide on the furl. You’ll notice the furl has a pointy end and a dull end, the pointy end goes towards the orifice. The feed tube material is rather stiff. On some models, it may be necessary to warm it up with a hair dryer in order to bend it. Be careful not to overheat it.

We’re going to take a half-inch wrench and loosen the feed tube assembly. Now let’s connect the feed tube assembly to the solenoid valve. Insert the orifice end into the solenoid valve. Slide the furl and the nut forward. Hand tighten it. Now get out the wrench and snug it up.

So now we’re going to change the strainer screen. This is the incoming water line, the solenoid valve, and the feed tube. There’s an arrow here indicating which direction the water flows through the solenoid valve. Here’s the tools we’ll need:
- 7/16 inch wrench
- half-inch wrench
- pair of needle-nose pliers
- and a common paper clip.

Now, we’re going to disconnect the water line. Loosen this up, pull the water line out of the way. Now we’re going to take the paper clip and straighten it out. Alright, that’s straight enough. Now we’re going to bend a small hook on one end of it. There we are. The small hook is going to be used to catch the strainer screen. We’re going to slide it in like this to grab the old one. So, we’re going to reach into the valve, grab the old strainer screen, pull it out, and dispose of it.

Now we’re going to take the new strainer screen, insert it into the solenoid valve, take the straight end of the paper clip and use it to push the strainer screen into place. Now all we have to do is reconnect the water line, tighten it up, and there we have it. It’s all done. Now the only thing we need to do is turn the water back on.

Now let’s insert the feed tube into the nozzle. Simply push it in. It’s friction fit; no glue is required.
