IceDry 30 2 Product design 2.1 Product description The desiccant dehumidifiers in the IceDry series have been developed to effectively dehumidify the air in cold stores in order to minimise frost and ice build-up The dehumidifier is equipped with an encapsulated rotor unit. The rotor casing is constructed of durable thermoset plastic and contains isolated sections that provide a precise balance for the dehumidification, reactivation and heat recovery airflows.

4. Remove all packaging material from the unit, check carefully to make sure that no damage has occurred during transportation. 5. Any visible damage must be reported in writing to Munters within 5 days and prior to installation of the unit.
IceDry 30 4 Installation 4.1 General IceDry dehumidifiers are intended for installation in cold stores with ambient air down to minus 25 °C. These conditions require that installation instructions are followed carefully as faulty installation can result in serious operational disturbances.
4.5.1 General recommendations NOTE! Vibration reduction. If there is a need to for reduction of vibrations from the dehumidifier, contact Munters for instructions. Refer to standard EN 1299+A1:2008. Due to the cold surroundings and risk of freezing, it is vital that all ducting are installed according to instructions.
IceDry 30 Ensure that access for operation and servicing is not restricted when designing and installing ducting. ■ For more information, see section 9.1, Dimensions and service space. To reduce noise and/or vibration being transmitted along rigid ductwork, good quality, airtight flexible ■...

IceDry 30 4.6 Installation examples — cold storage room (freezer) Munters recommends the following installations. If in doubt, contact Munters for advice. Note the service space requirements in section 9.1, Dimensions and service space. Figure 4.2 Position behind screen. 5 - 10 m Figure 4.3 Position far away from door / airlock.
IceDry 30 5 - 10 m Figure 4.4 Process air duct far away from door / air lock. CA UTION! UTION! UTION! Activate the main switch for the dehumidifier as soon as the unit has been installed. This allows the built-in heater to operate and prevents internal ice formation.
IceDry 30 4.8 Pre-start settings On delivery the operational parameters are set for use in a cold store. A number of alternatives, to minimise the risk of operational disturbance, can be set on initial start-up, see section 6, Control system.
IceDry 30 4.10 Airflow check and adjustment Contact Munters Service for dehumidifier installation and adjustment. The addresses to Munters can be found on the back page of this manual. CA UTION! UTION! UTION! If the process and reactivation airflows are not properly adjusted, the unit can malfunction. The airflow must be set to maximum 10% above the specified nominal value listed in section 9.2, Technical data.
IceDry 30 5 Operation 5.1 General The dehumidifier is equipped with an external electrical cabinet containing control panel, main power switch, mode switch, display and indicator lamps. The mode switch has two operating positions: Position 0: No dehumidification. The heater in the electrical cabinet and the reactivation heater is still in ■...
IceDry 30 5.4 External electrical cabinet Figure 5.1 External electrical cabinet Item Description Function Main Power Switch When the main power switch is in the ”0” position, the unit is not powered beyond the switch. When the main power switch is in the ”1” position, the dehumidifier can be started.
With high humidity values outside this will create a problem within a few hours. Contact Munters Service to discuss the best solution how to minimise the effects of a power supply failure. Operation...
CA UTION! UTION! UTION! Ask Munters Service for advice before switching off the defrosting function. 5.6.1 During operation Defrosting during operation (mode switch in position "1") means that the process fan stops for a short time, about twice a day, so that the rotor heats up. When the wet air temperature has increased to approximately 40 °C the process fan starts again.
IceDry 30 6 Control system 6.1 General The dehumidifier is provided with a programmable control system, which can be adapted to a certain extent. On delivery, the system is set to standard values for operation in a cold store. Figure 6.1 Control system panel 6.2 Structure...
