MCS300 2 Function overview The desiccant rotor is the adsorption dehumidifying component in the unit. The rotor structure is comprised of a large number of small air channels. The desiccant rotor is made of a composite material that is highly effective in attracting and retaining water vapour.
3.1 General The MCS300 is intended for indoor installation. The unit shall be placed in an upright position on a level surface. If the unit is stored prior to installation, place it in a roofed area, on a level surface where it is protected from impact, dust, frost, rain or aggressive contaminants.
4. Remove all packaging material from the unit, and 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. 6. Dispose of the packaging material according to local regulations.
The dehumidifier is only intended for indoor installation. Avoid installing the dehumidifier where there is a risk of water entering the unit, or in a very dusty environment. Refer to Munters for advice if in doubt. For unit and service dimensions, see section 10, Technical specification.
MCS300 3.8 Connection of ducts and hoses 3.8.1 General Follow the instructions below when attaching ducts or flexible hoses to the unit's air connections. Duct length should be kept as short as possible to minimise static pressure loss. ■ All duct and hose connections must be air tight and vapour tight to ensure full performance.
MCS300 Open airflow system The dehumidifier is placed outside the area to be dehumidified. Dry air is transported with ducting to the space to be dehumidified and the wet air is discharged in the vicinity of the unit or moved outdoors, see Figure 3.3 .
MCS300 3.10 Connecting the humidistat 3.10.1 General The connection socket for the humidistat is located in the storage compartment for the power cable, see Figure 3.4 . The appropriate plug for the humidistat is delivered with the unit, see section 3.10.2, Humidistat connection kit.
MCS300 3.10.2 Humidistat connection kit Follow the instructions below to assemble and connect the humidistat connection kit. 1. Connect the leads to pins 1 and 2, and the screen to the earth pin. Figure 3.5 Connection of leads A. Lead connections B.
MCS300 4 Operation 4.1 General The dehumidifier has three operating modes, see Figure 4.1 . Man: The dehumidifier’s fans, rotor and reactivation heater operate continuously. Auto1: The dehumidifier’s fans, rotor and reactivation heater are started/stopped by the humidistat. Auto 2: The dehumidifier’s fans and rotor operate continuously. The reactivation heater is started and stopped by the humidistat only.
