XIV. Cleaning
Deposits (e.g. lime) build up during the distillation process on the interior parts of evaporator
(11). This gradually reduces the quality of the distillate.
When there are considerable deposits in the evaporator, or when the quality of the distillate no
longer meets the requirements for the intended application, the evaporator must be cleaned.
When there are heavy deposits in the cooling spiral, they must be cleaned up latter; these
deposits however do not affect the quality of the distillate.
Producer cannot accept any warranty claims if the heater is damaged as a result of overheating
because the apparatus has not been sufficiently cleaned.
The following items are required for cleaning:
−
protective clothing, gloves and goggles
−
a suitable funnel
−
a funnel stand, minimal length 70 cm
−
a graduated jug of minimal capacity 2 litters
−
a suitable vessel for the disposal of the acetic acid
