Construction, description and function
1.2 Description
The steam generator in MEMMERT appliances with humidity control is supplied with
demineralised water from tanks that must be regularly refilled with commercially avail-
able demineralised water. Using demineralised water is imperative, as otherwise pumps
and pipes could become calcified.
With a central water supply, up to three MEMMERT appliances with humidity control
can be supplied with demineralised water. The tanks, and therefore refilling, are then no
longer necessary.
1.3 Function
Via the supply tube (Fig. 1, No. 4), tap water is fed through the filter cartridges (10) and
this way demineralised. The demineralised water is channelled, float controlled, to a wa-
ter supply tank (8) connected (6) with three tube connectors to the front of the appliance
(1). Up to three MEMMERT appliances with humidity control can be connected here.
The conductivity of the demineralised water – and thus the correct function of the filter
cartridges – is measured continuously by a monitoring unit (5), supplied via the connec-
tion on the front of the appliance (2) with 12 V direct current by the included plug-in
power supply unit. If the conductivity exceeds a certain value, the LED at the front will
flash (3, see also page 10) and a warning signal will sound. Then, the filter cartridges
must be replaced (see page 10).

1.5 Intended use and improper use
The central water supply must only be used to supply MEMMERT appliances with humid-
ity control with demineralised water. Any other use is improper, and may result in dam-
age. In particular,
► connecting other appliances to the central water supply is not permissible
► filling the central water tank with fluids other than drinking water with a pressure of
maximum 2.5 bar and a maximum temperature of 40 °C
► operation with other filter inserts than those provided by the manufacturer
► attaching and fitting parts not approved by the manufacturer
