[Histonet] calcium buildup

[Amos Brooks]

Hi,
    We have the same instrument. I love the thing to death! The water
reservoirs can be removed by pulling them out like the other ones. The
water input remains in place while the rubber gasket slides off. By the
way, do this with the instrument off so it doesn't spill all over the
place. Wash out the reservoir well then you can remove the water input by
holding the large stainless steel nut at the back and twisting counter
clockwise. If the calcium buildup is bad some channel lock pliers may come
in handy. Don't loose the rubber gasket that is behind the stainless steel
nut. The majority of the crud will come of with a scrub in detergent, but
if it is really bad a soak in dilute HCl should help. You could leave it
soaking overnight in hot water too. This would also be a good time to
remove the stainless steel trays the reservoirs set on and clean out the
drain. Fungal growths can build up there and can actually clog the drain if
left unchecked. Actually this should all be part of a periodic maintenance
plan. We have a service take care of it for us (Belair in New Jersey comes
out for us) and I also take it down and clean it out before our Christmas
break.
