Datacolor CONDITIONER™ (MB2) 06/2017

Remarks on cabinet with lights:
Turning on the illumination modifies the operating range, and the humidity set-point at 20°C must not
be lower than 30 % RH, otherwise stable humidity control is not guaranteed
Outside the optimized operating range there is increased risk of condensation, which can trigger the
internal residual current operated device if the illumination is switched on and thus cause switching off
the unit. The residual current operated device permanently switches off-tension the unit as soon as
the residual current exceeds 30 mA.
Due to the construction of the cabinet with light, no icing occurs in the inner chamber during the de-
humidification. The cabinet can be operated permanently without manual defrosting.
Heat emission of electrical devices connected inside the cabinet may modify the temperature
and humidity range.
The cabinets are 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. The humidity system must be activated.
•
Set the temperature set point to 60 °C /
140 °F
for approx. 2 hours (Manual mode).
•
Only then, shut down the cabinet at the main power switch (1) and close the water
supply tap.
Having turned off the cabinet by the main power switch (1), always close the water supply tap.
If you operate the cabinet at high humidity and then immediately turn off the cabinet, the internal
wastewater collector may overflow due to the condensate. This may lead to the emergence of water at
the cabinet.
CAUTION
Overflow of the internal wastewater tank due to condensate.
Emergence of water at the cabinet.
∅
Following high humidity operation, do NOT directly turn off the cabinet.
Pump off the condensate before shut-down:
•
Set the humidity to 0 % r.H. The humidity system must be activated. Operate the
cabinet for at least 2 hours.
•
Only then, shut down the cabinet at the main power switch (1) and close the water
supply tap.
