Repair work at the humidifying and dehumidifying system
Function of the humidifying and dehumidifying system
Freshwater
You can supply the unit with freshwater via a water pipe or by manually filling a freshwater can. You can fix
the can (optionally available) on the unit rear or place it next to the unit
In order to guarantee perfect humidifying, observe the following points with regard to the
freshwater supply:
- Supply pressure 1 to 10 bar when connecting to a water pipe
- Type of water: deionized (demineralized) water.
- To guarantee humidification during 24 hours even at high humidity set-points with manual
water supply, we recommend filling the freshwater can (option) daily at the end of the day.
- Water intake temperature NOT below +5°C /
41°F
and not exceeding 40°C /
104°F
.
BINDER GmbH is NOT responsible for the water quality at the customer.
Any problems and malfunctions that might arise following use of water of deviating quality is
excluded from liability by BINDER GmbH.
Automatic fresh water supply via water pipe
With this type of supply, the humidification module is continuously functional without any precautionary
measures.
Manual fresh water supply via freshwater can (option)
With this type of supply, the humidification module is functional only if the water can is sufficiently filled.
Check the filling level daily. The water reserve in the water can is sufficient for one up to several days,
depending on the humidity demand (set humidity set-point, number of door openings).
Dehumidifying system
After switching on the humidity switch (located on the lateral control panel), the KBF humidifies or dehumidi-
fies appropriately to reach the selected humidity set-point at the set temperature.
Appropriate dehumidification takes place via concerted dew point underflow of different evaporators in the
cooling system. The condensate forming is drained off as waste-water.
With decreasing temperature courses and the humidity system switched off, cooling system operation may
cause dehumidification of the loading material.
