page 69/106
Entry of the humidity set-point 0 % in defined program sections permits completely turning off
humidity in Program Mode and thus attaining faster temperature changes.
The climatic chamber KBF-LQC is equipped with a door heating system to prevent condensation
in the door area.
If the set points for temperature or humidity are outside the optimum range, condensation can arise 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.
¾
Dry the appliance completely before shut-down:
•
Set the humidity to 0 % r.H. and turn on humidity switch (4).
•
Set the temperature set point to 60 °C /
140°F
for approx. 2 hours (Manual mode).
•
Only then, shut down the unit at the main power switch (3) and close the tap of the
water supply.
Having turned off the unit by the main power switch (3), always close the tap of the water sup-
ply.
If you operate the unit at high humidity and then directly turn off the unit, the internal waste-water collector
may overflow due to the condensate. This may lead to emergence of water at the unit.
CAUTION
Overflow of the internal waste-water tank due to condensate.
Emergence of water
at the unit.
∅
Following high humidity operation, do NOT directly turn off the unit.
¾
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 tap of the
water supply.
13.1 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 about 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 waste water 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 a freshwater can (option,
chap. 17.9) You can fix the can on the unit rear or place it next to the unit.
