BINDER MK 115 - Manual (Page 77)

MKF + MKFT (E3.1) 07/2014 page 77/114
The MKF / MKFT alternating climate 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 unit operate
for approx. 2 hours with closed door. Remove the access port plugs.
• Only then, shut down the unit at the main power switch (3) and close the water sup-
ply tap.
Having turned off the unit by the main power switch (3), always close the water supply tap.
If you operate the unit at high humidity and then immediately turn off the unit, the internal wastewater
collector may overflow due to the condensate. This may lead to the emergence of water at the unit.
CAUTION
Overflow of the internal wastewater tank due to condensate.
Emergence of water at the unit.
∅
Following high humidity operation, do NOT directly turn off the unit.
 Pump off the condensate before shut-down:
• Set the humidity to 0 % r.h. and turn on humidity switch (4). Operate the unit for at
least 2 hours.
• Only then, shut down the unit at the main power switch (3) and close the water sup-
ply 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 produced steam is main-
tained on a stable pressure level and is thus available 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 unit 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.
