With all UV lamps, there comes a point where you will need to replace it. Here is a simple guide on how to do it yourself with regards to a Van Remmen UV unit.
First, you need to take out the old lamp. To do this you need to undo the black locking plug at the end of the chamber. I would advise that before you do so, just loosen of the cable gland at the top of it a touch. If it’s gripping then you will be twisting the cable round as well as undoing the locking plug which is much harder.
Once the locking plug is free, you will need to disconnect the end plug and the lamp. This is a push fit connection so a bit of pull and the most gentle of wiggles will do the job here. Once the lamp is free remove it in as straight a line as possible, these will come out easily if level and if you start to feel it gripping then you’re pulling it on an angle. Breaking the lamp here doesn’t matter, we’re just trying to not make a mess.
While the lamp is out we recommend that you have a peek down the inside of the quartz tube with a torch, any damage spotted here could save you time and money down the line.
When putting the new lamp in it’s important to not touch the glass part of it, some of the lamps can be quite long so if it’s going to be a bit tricky then wear gloves. Where the lamps run really hot, the oil from your skin that is left after you touch it creates an area that gets much hotter than the rest of it, this area will be much weaker than normal after a while.
From here it’s just the reverse of taking a lamp out. Slide the lamp in most of the way, reconnect the end plug, screw up the locking plug, tighten the cable gland and you’re there. See, how easy was that!!! If you do run into any trouble along the way though, just give me a ring. Ryan’ll fix it.
