ComDry M190Y Dehumidifier WARNING • The unit must not be splashed with or immersed in water. • All electrical installations must be done by an authorized electrician in accordance with local regulations. An incorrect installation can cause electrical shock hazards and damage to the unit.
The rotor is divided in two zones. ComDry M190Y uses the same inlet airflow for process air and for reactivation of the rotor. The airflow to be dehumidified, process air, passes through the largest zone of the rotor and then leaves the rotor as dry air.
• Any damage to the unit must be documented with photos. • Any visible damage must be reported in writing to Munters within 3 days and prior to installation of the unit. • Discard the packaging material according to local regulations.
ComDry M190Y Dehumidifier 5. Installation 5.1. Safety WARNING All electrical installations must be done by an authorized electrician in accordance with local regulations. An incorrect installation can cause electrical shock hazards and dam- age to the unit. The unit must never be connected to another voltage or frequency than what is speci- fied on the identification plate.
ComDry M190Y Dehumidifier 1. Process / Reactivation air 2. Dry air 3. Wet air 5.3. Open system The dehumidifier is placed outside the space to be dehumidified. The installation is used to solve the following problems: • When moisture damaged objects are to be dehumidified.
The dehumidifier is only intended for indoor installation. Avoid installing the dehumidifier in a damp environment where there is a risk of water entering the unit or in a very dusty environment. If in doubt, contact Munters. NOTE It is important that the intended installation site meets the location and space require- ments for the equipment in order to achieve the best possible performance and trou- ble-free operation.
ComDry M190Y Dehumidifier NOTE Horizontal ducts must be installed with a slight decline away from the dehumidifier to drain possible condensation. The decline must be at least 2 cm/m of duct. Drainage holes (5 mm) should be made at low points of the duct to prevent water accumulation.
ComDry M190Y Dehumidifier 5.6. Electrical connections The dehumidifier is delivered with a 2.7 m long power cable, with a plug for connection to an earthed outlet. WARNING All electrical installations must be done by an authorized electrician in accordance with local regulations.
ComDry M190Y Dehumidifier Remove the cover. CAN bus ports with empty termination plugs. 5.8. Accessories Wall bracket For mounting the unit on a wall. Stub pipe kit Used when there is a need to connect an inlet duct or hose to the dehumidifier.

ComDry M190Y Dehumidifier Remote control Makes it possible to control the unit from a distance, delivered with a 10 m cable. External signal box Used when there is a need to connect to an external control system. Remote RH/T sensor For external measuring of humidity and temperature.
ComDry M190Y Dehumidifier 6. Operation 6.1. Safety WARNING The unit must not be splashed with or immersed in water. The unit can restart automatically without warning following a power cut. Do not operate the unit if the power cable or plug is damaged, risk of electrical shock.
ComDry M190Y Dehumidifier 6.3. Humidity control The ComDry dehumidifier is equipped with a sophisticated microprocessor based control system. This, in combination with the built-in humidity/temperature sensor in the process air inlet, makes it possible to set both the control and presentation of the humidity to either relative humidity (RH%), dew point (Dp °C) or absolute humidity (X gr/kg).

ComDry M190Y Dehumidifier Press the On/Off button (C) once to start the dehumidifier. If the measured humidity is lower than the Set Value, the green operating indicator (B) will start to flash in a long on/short off sequence. Depending on fan mode setting, the process fan will run or not. The unit is now in stand-by mode.
It is recommended to contact Munters for service or repair. Operating faults can occur if the unit is maintained insufficiently or incorrectly. Munters Service can offer a service plan adapted to suit the conditions of a specific installation. See contact details at the back of this manual.
