BINDER KBF 115 - Manual (Page 69)

KBF / KBF P (E5.3) 09/2014 page 69/110
Range A: Control range of temperature and relative humidity
Range B: Discontinuous range (no continuous operation)
Range C: In this range, deviations of the technical data are possible
Heat emission of electrical devices connected inside the chamber may modify the temperature
and humidity range.
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 constant climate chamber KBF / KBF P 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.

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 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 the “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.
