MKF+ MKFT (E3.2) 07/2017 page 69/115
The chamber is equipped with a door heating system to prevent condensation in the door area.
CAUTION
Condensation by excess humidity.
Danger of corrosion on the housing after operating at humidity values > 70 % r.h. for
a long period.

Dry the appliance completely before shut-down:
•
Set the humidity to 0 % r.h. or turn off the humidifying system at humidity switch (4).
•
Set the temperature set point to 60 °C / 140°F (Manual mode). Let the chamber op-
erate for approx. 2 hours with closed door. Remove the access port plugs.
•
Only then, shut down the chamber at the main power switch (3) and close the water
supply tap.
Having turned off the chamber by the main power switch (3), always close the water supply
tap.
If you operate the chamber at high humidity and then immediately turn off the chamber, the internal
wastewater collector may overflow due to the condensate. This may lead to the emergence of water at
the chamber.
CAUTION
Overflow of the internal wastewater tank due to condensate.
Emergence of water at the chamber.
∅
Following high humidity operation, do NOT directly turn off the chamber.

Pump off the condensate before shut-down:
•
Set the humidity to 0 % r.h. and turn on humidity switch (4). Operate the chamber
for at least 2 hours.
•
Only then, shut down the chamber at the main power switch (3) and close the water
supply tap.
14.1 Function of the humidifying and dehumidifying system
Humidifying system
The humidifying system is located in the humidity generation module. In a cylindrical container with a
volume of approx. 2 liters an electrical resistance heating evaporates water. The water content is kept
exactly at the boiling point, and thus steam can be immediately generated in sufficient quantity for rapid
humidity increases or for compensation of humidity losses, e.g. by door openings. Condensation forming
on the outer walls of the useable volume is led through a water drain in the outer chamber into the
wastewater can which is pumped off automatically to the wastewater pipe when required.
Freshwater
You can supply the chamber with freshwater via a water pipe or by manually filling the internal freshwater
can. It is not necessary to switch between both possibilities. When connecting to a water pipe, the water
can automatically fills up. The can is located behind the right door of the humidity generation module.
