GSS/GSSM Dispensers – Installation Guide

 Something to note – these dispensers should always be installed as close to the dispense point as possible. You also want to make sure their air and fluid lines don’t have any kinks or obstructions.  When it comes to grease dispensers, they can be mounted in any orientation, but when it comes to oil, you want to make sure the inlet port is positioned at the bottom and the lead plug is at the top for both. It’s best to place the regulator and the pressure gauge near the air and fluid inlet points. That way you can see them and adjust them if you have to.

To begin the process, install your air and material fittings. Make sure you use thread sealant when installing those pipe thread fittings. Something to consider when connecting your air supply is that GSS units will connect directly to their air supply, while GSM units will receive air via manifold. Some manifolds will have one air inlet for all mounted GSM units, while others will have separate air for each individually firing dispenser. You can install the dispenser however your team prefers using the mounting holes on the dispenser or on the manifold. But whatever you do, do not drill your own holes into the dispenser.

• Next, you want to determine the size and length of your supply lines. You want to make sure the material is going to flow freely, so give yourself a little bit of slack to ensure there’s flexibility in the lines. Connect the supply and dispense line to their designated ports. At this point, it’s a good time to make sure that material is flowing freely.
• Next, you want to bleed the air from your supply lines. The worst thing you can do for your dispensing process is to use material with air in it. So we want to make sure that you don’t do that. So, you’re going to take 2 to 3 inches of translucent tubing (quarter inch), and you’re going to install that onto the bleed plug screw. Okay.
• Next you’re going to take a 5/16 wrench. Slowly loosen it. If it’s not loosening independent of the bleed plug screw, you can take a second seven 16th wrench. And you can just hold it steady right there. After material begins flowing into the tube, you can tighten it right back up, and using a set of pliers or your muscly fingers, you can take the tubing off of the bleed plug screw, and then you can run a few to spend cycles. Make sure everything is flowing nice and easy.
• You can double check this by weighing or measuring the dispense volume. If any adjustment is necessary, we can teach you how to fix that. That’s what the video is for. To alter your dispense volume, you need to change your adjustment assembly. We have two types of assemblies. We have our standard adjustment assembly and our micro dial. Click to the next section for your specific type.

If you have a standard adjustment assembly you’re going to pull up on it to unlock it. You can use the volume knob to adjust how much comes out clockwise for more, counterclockwise for less. You’ll feel clicks as you turn. Each click equates to 1/40 of your total dispense volume range. Then you can test the output. You might have to run it a few times after you adjust everything.

Once you get the volume you want. You can push the adjustment assembly back down, and then you can skip this next step about micro dial.

If you have a micro dial, you’re going to want to slide the lock on the side of the dial to unlock it. Then you can use the volume knob to adjust how much comes out clockwise for more, counterclockwise for less. The micro dial features labeled graduations, meaning you can check what volume level you’re at, the exact volume of each number will vary between dispenser sizes. You can test the output. You might have to run it a few times after you adjust it. And then once you have got what you need, you can lock it back in place. Run the dispenser a few times to make sure the stroke sensor is working properly.

• If your stroke sensor is still being weird, don’t worry, we have an entire video on how to fix it. I’ll put it right here.
• Let’s talk PSI. Verify that your air pressure is somewhere between 60 and 100 psi. Your material supply shouldn’t be more than 200 for grease or more than 50 for oil. It’s important not to over pressurize. Don’t do it. You don’t want to put too much pressure on the situation. Okay. It’s like a first date. The proper amount of pressure for that situation is good. If you’re still having issues, we have a troubleshooting video that you can watch. It will be here.
