wax stick woes & nozzle sealing hacks for Duplo PFi BIND 2100 PUR

[gummib34r]

Just recently got my hands on a Duplo PFi BIND 2100 PUR Binder, and man, this machine is sweet!
It's been running like a dream, no issues at all... except I'm already running low on those little wax sticks that came with it.
You know, the ones you use to seal up the nozzle after you clean it.

So I wonder, can I just grab a regular old wax candlestick and use that to seal the nozzle after a clean out?
Or is it some kind of super special adhesive glue stick that I absolutely have to get from Duplo?
I'm trying not to buy something crazy expensive if there's a common alternative.

Also, for those of you with PUR binders, how often do you typically clean and seal your nozzles? Just trying to get a feel for best practices!
Any advice would be a huge help!

I'd strongly advise against using a generic wax candle to seal the nozzle. The risk of contaminating the PUR glue system with unknown oils or additives from the candle is very high. A contaminated glue pot can lead to a very expensive service call and extensive downtime. The cost of the correct sealing sticks is small compared to the potential for a major repair bill.
Regarding the cleaning schedule, that's entirely dependent on your production volume. How many hours a day or week is the machine typically in operation?
