The Intelligent Microfilter
TIPS AND TRICKS
With the following tips and tricks you can prevent damages to your Vario
microfilter and help to prolong its lifespan.
1) Water leaks or sprays from around the pistons when pumping:
Check the o-rings on the pistons (2 o-rings per piston). Clean o-
rings and pistons with a soft cloth. The o-rings should not be brittle
or damaged and need to be kept lubricated at all times. Apply
additional silicone grease generously, as needed. Replace any o-
rings that are damaged or worn, making sure you lubricate the
new o-rings before putting them on the pistons. Be careful that the
o-rings do not get pinched when you reassemble the filter.
2) Vario filter does not draw water:
Unscrew your Vario, remove the ceramic prefilter disc from the fil-
ter housing and clean the prefilter with the cleaning pad that was
packaged with your filter. Put the cleaned ceramic prefilter disc
back onto the filter housing in LONGER LIFE or FASTER FLOW set-
ting. Holding the pumphead in your hand, immerse the input hose
in water and pump the unit (still without the filter housing) a cou-
ple of times until it draws water. If it does not draw water, turn the
pumphead upside down, fill the inside partially with water, and
pump a few times to “prime” the pump, making sure that the input
hose is still immersed in the water. As soon as your Vario draws
water again, reassemble it and continue pumping normally.
If it still does not draw water, check the o-rings on both pistons (2
o-rings per piston). The o-rings should not be brittle or damaged
and need to be lubricated at all times (see point 1).
3) Pumping becomes increasingly difficult and water output
decreases:
Unscrew your Vario and remove the ceramic prefilter disc from
the filter housing. Scrub off any dirt particles from the prefilter
with the cleaning pad that was packaged with the Vario. Put the
cleaned ceramic prefilter disc back onto the filter housing in
LONGER LIFE mode and reassemble the filter. If the pumping is
not easier, turn to FASTER FLOW and reassemble. If pumping is
easier, the ceramic prefilter disc needs to be srubbed deeper or it
should be replaced. If the pumping is not easier in FASTER FLOW,
the pleated filter is clogged and needs to be replaced.
