Arzel Zoning
Arzel's pneumatic pump powers all of our zone dampers. This video shows how to test the pump if you suspect there's an issue. For use with HeatPumPro, MPS, AirBoss, and GTPro panels that are in our polycarbonate enclosure. Here's how to test the pump in a metal enclosure. #hvaczoning #hvactroubleshooting #hvactechnology
Hello, and welcome to Arzel Zoning, where we want to show you how to test the pump in our new plastic enclosure. The pump has a couple of major differences. One, there’s a lot more service room so you can get to these ports now without having to remove the pump, and two, the ports in the front are now being plumbed into a muffler installed behind the control board which makes this one of the quietest Arzel panels we’ve ever heard.
Your back left port is pressure. We’re looking for positive 40 inches of water column or better there. Your back right port is vacuum. We’re looking for -35 in of water column or better there. Slide the airline off your back port, connect your manometer hose, and once your monometer hose is connected, turn our pump on with the MPS switch.
We’re seeing that we got more than 60 in of water column, which is a lot better than the 40 we’re looking for. The back left-hand port, we got plenty of pressure. We’ll go ahead and turn that off, reconnect our pressure line, and then we’re going to take the vacuum line off. Once that’s off, we’ll get our manometer connected up there and we will see what we have for vacuum. We see that we have negative 57 inches. That’s plenty of vacuum; we know that the pump is operating correctly. So we can move from there to test our solenoid and our dampers.
