3 Safety notes 3 Safety notes The following general safety notes must be observed for the assembly, installation and operation of the cooling unit: – The assembly, installation and servicing of the cooling unit may only be performed by properly trained specialists. – The mains connector of the cooling unit must only be connected and disconnected with the system de-energised. The device must be protected with a pre-fuse. – No changes may be made to the cooling unit.
4 How it works 4 The Rittal Thermoelectric Cooler uses the Peltier effect for cooling. This effect is based on the principle that an electric direct-current flowing through a circuit consisting of two different metals causes the cooling of one contact point and the heating of the other contact points. An appropriate layout for the cooling production is designated as Peltier element. When the Peltier effect is used for enclosure climate control, an air flow is fed over the upper and lower connection point.
5 Control 5 Control Fan speed in the external air circuit The Rittal Thermoelectric Cooler controls the cooling capacity of the Peltier elements and the air throughput of the integrated fans so that the required internal temperature of the enclosure or the operating housing is set with high accuracy. For this purpose, the device permanently monitors the air entry temperature at the warm air entry (internal circulation).

7 Device mounting 7 Device mounting The following principles must be observed for determining the mounting position on the enclosure or operating housing: The direct incidence of cold air on temperature-sensitive components must be avoided! Components with integrated fans determine the cooling air routing in the enclosure or operating housing. The mounting position of the cooling unit must be chosen so that the cooling air flow supports the heat dissipation of these components.

8 Filter mounting 8 Filter mounting The Rittal Thermoelectric Cooler can be equipped with a device filter (supplied). An appropriate filter unit is recommended when the cooling unit is used in ambient air subject to dust. 9 Mounting the condensate discharge GB The Rittal Thermoelectric Cooler is equipped with a condensate discharge. Note: When a filter unit is used, it must be cleaned regularly or, if necessary, replaced.
10 Electrical connection 10 Electrical connection GB Danger! Warning of a dangerous electrical voltage. Danger to life and health in case of non-observance! The Rittal Thermoelectric Cooler is available as version with integrated multi-range power pack (100 – 240 V) and as 24 V variant (without integrated power pack). Mains PE Alarm L1 N PE X1 10.1 Connection data – The mains voltage and frequency must correspond to the values stated on the rating plate.

Maintenance and cleaning 16 Maintenance and cleaning GB Danger! Prior to any cleaning or maintenance work, the power to the cooling unit must be disconnected! 16.1 Maintenance The Rittal Thermoelectric Cooler is low-maintenance. Note: When the filter is replaced, use only filter materials approved for the Rittal Thermoelectric Cooler.
Fault correction 17 Fault correction GB Fault description Possible cause Correction The unit does not switch on. No power supply. Check the mains connection and the pre-fuse. The unit does not cool adequately. The air circulation in the enclosure is impaired. Check the air circulation inside the enclosure. Check, in particular, those components equipped with a fan. Check the free spaces above and below the main heat dissipation sources. Ambient temperature too high.
Disposal GB 18 Disposal 19 Guarantee To ensure the material reuse of the recyclable packaging materials, they must be delivered to the local collection sites. The cooling unit must be delivered to a waste management service provider that ensures the correct reuse of the recyclable parts and the proper disposal of the rest.
