    Machine base (foot) – Outside view Figure 3: Machine base (foot) - mounting on the baseplate Figure 4: Figure 5: Seismic feets are used for seismic and high wind gust regions 3.8. Filter assembly group coolant circuit (accessories) The water filter protects the cold water circuit against dirt. The set, consisting of a filter, fitting and two shut off valves, is enclosed with the chiller in a separate pack and must be fitted onto the cold water inlet of the chiller from the outside when the chiller is installed.

  • Page 23: Remote Control Panel (Accessories)

    3.10. Remote control panel (accessories) In the event that the chiller shall be operated not from the machine itself but from a different operating location, the chiller can be delivered with a remote control panel. Thereby the same display that is already installed in the chiller is mounted together with a rail to the operating voltage supply in one miniature housing.

  • Page 26 : Definition of the safety symbols Table 8 Observe the instruction manual! Before opening the machine, disconnect the machine from the power supply. The machine may only be opened 5 minutes after it has been disconnected from the power supply. Beware of dangerous electrical voltage! If the machine is only turned off by means of the main switch, some of the terminals in the control cabinet will still be under dangerous voltage.
  • Page 27 The following hazard warnings apply in particular to the machine: : Hazard warnings Table 9 ATTENTION! Work on the chiller must be carried out by properly qualified, competent personnel! The surfaces of pipes and components of the refrigerant and cold water circuit and electrical equipment can be very hot during operation and even for a while after.

  • Page 29: Safety Devices, Guards And Safeguards

    4.4. Safety devices, guards and safeguards 4.4.1. High-pressure limiter The high-pressure limiter (PZH) is a pressure switch with manual reset. The PZH limits the condensing pressure and switches off all compressors via their load contactors when the maximum permitted system operating pressure is reached. It is part of the safety chain. The PZH is installed on the refrigerant collector for the chiller types cBoxX 60 –...

  • Page 30: High-Pressure Monitoring

    4.4.2. High-pressure monitoring If the high pressure in the refrigeration circuit of your machine increases to a maximum value, the compressors are switched off via the high-pressure limiter (see Chapter 4.4.1 High-pressure limiter). A manual reset is required. The high-pressure monitoring on the other hand reduces the compressor output before the PZH's switch-off value is reached.

  • Page 31: Personal Protective Equipment For Servicing Work

    4.5. Personal protective equipment for servicing work Servicing work on the machine includes all work for which the machine is opened and one or more cover panels are dismantled. In particular, this includes cleaning work in accordance with Chapter 9 Cleaning and maintenance work in accordance with Chapter 10 Service. Before work is carried out on the chiller the protective equipment described in Table 9: Definition of the safety symbols must be used.

  • Page 32: Airborne Sound Emissions

    4.6. Airborne sound emissions The airborne sound emissions data is given as the sound pressure level, measured at a distance of five metres without reflection. Its maximum value is shown in the technical data. This only occurs at the highest fan speed at the air intake side of the chiller (Figure 9, measuring point [1]). The emissions in [2] to [4] are generally around 10 % lower than [1].

  • Page 33: Vibration

    4.7.2. Vibration The chiller is designed so that the vibrations caused by the compressor are largely isolated by the chiller's frame. To minimise the effect of vibration still further it is possible to install the chiller with optionally available levelling feet (3.20 Levelling feet . These are fitted with damping elastomers. 4.8.

  • Page 42: Surface And Foundation

    6.2.6. Surface and foundation The surface on which the machine is installed must be flat and horizontal. All the machine's feet must have uniform contact with the ground. Ensure that the ground/subsoil has sufficient load bearing capacity. According to the installation instructions (Appendix III) a continuous concrete foundation with the given minimum size is recommended.

  • Page 43: Hydraulic Installation

    6.2.11. Hydraulic installation The system designer is responsible for choosing the material and the cross-section of the hydraulic connections between the chiller and the application. Other dependent factors include the accepted pressure loss in the connection lines and the available pump pressure. When designing the connections attention must also be paid to the minimum flow rate to be maintained and sufficient resistance to the maximum pump pressure.

  • Page 44: Filling

    6.2.14. Filling Once the hydraulic installation of the overall system has been completed, the chiller can be filled. All shut-off valves in the cold water circuit must be opened. In the standard version the machine does not have a filling connection. To fill the system, provide a filling connection in the process circuit.

  • Page 45: Electrical Installation

    6.2.16. Electrical installation ATTENTION! The electrical installation, testing and commissioning may only be carried out by qualified personnel. Note and follow the local regulations. ATTENTION! Do not switch on the chiller until the hydraulic installation is completed and the machine has been filled as specified in Chapter 6.2.15. Otherwise the machine could be damaged.

  • Page 46: Commissioning

    Once the electrical installation has been completed the phase sequence must be tested. This is done by checking the rotational direction of the pump. This has a rotational direction arrow on it. If the rotational direction does not match the arrow, the phase sequence can be corrected by swapping two phases at the main supply.

  • Page 48: Control

    8.4. Control The chiller's control consists of a control board and a control panel, which communicate with each other via a BUS connection. The control board operates autonomously so that if the control panel or communication fails, operation continues to be possible if no other fault prevents operation. The program, target / setpoint values, parameters and times are stored in an Eprom in the control and are therefore retained even in the event of a power failure.

    8.7.2. Cold water feed temperature control In the normal case the sensor in the tank (system with tank, with pump) is used to control the cold water feed temperature. If this sensor fails, the control switches internally to the sensor in the cold water return and the setpoint value is increased by a defined value.

  • Page 57: Compressor Control

    8.7.3. Compressor control The control is defined for a refrigeration circuit with a maximum of four compressors. The number of compressors is selected by means of coding resistance. The number of compressors is determined once when the control is restarted (switching on of the operating voltage) and is compared with the number of the last restart.
