We have an Isotherm
4201&4701 ASU Magnum units serving as refrigerator
and a separate freezer
unit, it came factory installed with one filter, after arriving in the USA from France
the filter was clogged so I cleaned it and thought not much of it......it came clogging so I installed two see through filters...all is well, not, every year there is a problem I have replaced three pumps, two voltage reducers and two electronic units. The mystery is why one of the pumps, brand new does not pump water
in but it does from a bucket ( so it works) and it is the lowest of the units so it gets its water
supply first.......any ideas.
the INdel Webasto guys in Fla are very helpful but they can't figure it out and the folks in the factory think its the double filter system, but this does not effect the other two. ..??????
