1 Hints on the manual This handbook contains instructions for the installation and operation of door or side-mounted, bolt-on Cooling Units provided by Pfannenberg. In this manual, safety recommendations and other information are structured as follows. If the measures described in the following are not strictly observed there is danger to life and health.
(Also refer to warranty 16 Any damage must be reported immediately to the forwarding agent Moreover, the latest edition of the "Pfannenberg After Sales Service Declaration" shall apply. •Before disposing of packing material ensure that it does not contain any loose components.
6 Safety Cooling units produced by Pfannenberg are designed for use in dissipating heat from switch cabinets (IP 55). The cooling unit is only suitable for installing on the stationary operation. Only the authorized specialist can work on the cooling system and electrical components.
12. IP55 protection class Please refer to technical data for the detailed function of the cooling unit. (See section 8) 7.2 Operating principles The compressor (1) compresses the refrigerant until high pressure is achieved. During this process temperature increases. In the condenser (2) heat is dissipated to ambient air, the coolant becoming liquid. The condenser fan (5) takes ambient air in through the condenser, and then it releases the air.In the expansion valve (3) the pressure of the coolant drops.

impede air circulation in the internal cabinet. • The power supply must be switched off when installing the cooling unit. • site of installation must be protected against contamination. If the cooling unit is mounted on an switch cabinet door, it must be confirmed that hinges can support the additional weight or that the switch cabinet will not topple over when the door is opened.
9.3 Electrical connection • The cooling unit must be connected to the mains by means of a disconnecting device with a contact gap of at least 3mm when switch off. • No temperature regulator allowed to be series-connected to the cooling unit up-stream feed. •...
Communication Connection: The unit supports standard Modbus protocol and RTU mode. The factory default communication address: "1", Bau: "9.6Kbps". RS485 allows 32 units to be connected together as a network. In order to link cooling units, following methods shall be taken: •...
generate an alarm when there is a failture during power-on self-test. ’ switched on without the front cover mounted, otherwise it will be damaged by poor heat dissipation. 11.2 Operation display The cooling unit is provided with an operation display,after the power supply is switched on, then cabinet internal temperature is shown,This indicates the unit works properly.
11.5 Human perception low noise mode When the human body sensing device senses movement of speed between 1.0 ~ 1.5 m/s near the cooling unit, internal fan goes into low noise mode. Low noise mode runs with time relay to avoid frequent on and off. Unit exits from low noise mode when no further movement is detected.
