I was talked into the Vario 3 because they were out of the basic version. I understood that it could somehow dose 3 seperate lines at 3 seperate rates... <duh>
It doses three sperate lines at the EXACT same rate. That is why I have the credit, I returned it.
anyhow, I had it turned all the way down and running 24hrs a day for two days. It was too hot to touch the case. I thought the plastic was ready to melt. I wrote a note to J.sprung. He advised against that:
Dear Carl,
Thanks for writing. The Vario3 dosing pump is not intended for continuous operation. The heating is also made worse by
running it at a slower speed! Faster is better for long running times. If you need to run it over the course of a whole day, you
can use an interval timer (the kind used for powerhead wavemakers) to turn it on for about 10 seconds and then off for 10
seconds or more, which would prevent it from heating up too hot. The Vario3 comes with a sophisticated programmable timer
for dosing at intervals as short as 2 seconds, but this timer cannot be used for the 10 on 10 off idea I just described due to the
number of programmed events that would be required.
Sincerely,

Hello.
I just recently purchased a Vario 3 dosing pump. Yesterday while I was tinkering with it, it ran all day at a very slow setting. I
found the body of the pump was VERY hot to the touch. Is it OK to run this pump at a slow setting for long legnths of time?
Thanks
Carl Shelton
