Operating instructions
Decalcification takes about 2.5 hours.
If, during installation, it is difficult to install
the filter cartridge or circulation adapter,
use a small amount of soap on the O-rings.
Never use grease because the O-rings are not
resistant to grease.
You will find more information about the
access door in the operating instructions
for the AquaGo instant water heater.
Decalcification frequency
Lime scale occurs especially as a result of pre-
cipitation from “hard” water. The AquaGo must
be decalcified regularly depending on water
hardness and hot water consumption.
