  • Page 3: Safety

    This cooling unit contains fluorinated greenhouse gas covered by the Kyoto protocol. In this STULZ unit the R410A refrigerant is used. Refrigerants are volatile, or highly volatile fluorinated hydrocarbons which are liquefied under pressure. They are incombustible and not hazardous to health when used as intended.

  • Page 4: Safety And Environmental Requirements

    Splashes of fluorinated hydrocarbons in the eyes can be blown out or fanned out by an assistant. Then rinse with water. Independent conversion and manufacture of replacement parts The system may only be converted or modified after consultation with STULZ. Original replacement parts and re- placement parts/accessories authorised by STULZ are an aid to safety. Unacceptable operating methods The operating safety of the system is only guaranteed when it is used as intended.

For a higher energy efficiency of open loop applications, please consider the following recommendations: • Minimize mixing of hot and cold air between the aisles at the end of the server rows and on their top. The air di- scharge from CyberRow units is already designed to reduce this mixing.
  • Page 31 The number of racks served by one CyberRow unit, as well as the distribution of the units in the rows, must be de- cided from time to time according to the heat load per rack and the desired redundancy in case of failure.

    6.4 Water connection (GS, GES, CW units) CyberRow CW air conditioners must be connected to a circuit with chilled water, including either a chiller or a dry cooler or a cooling tower. For chilled water circulation, pumps have to be provided. These pumps must be selected according to total pressure losses in the hydraulic circuit.
  • Page 50 On new or renovated condenser water systems, ensure that the external pipework is thoroughly flushed, to remove construction debris and other particulate matter, before connecting to the new Stulz cooling units. A strainer should be fitted at the unit inlet, to protect the heat exchangers from fouling and possible blockage.

    6.5 Condensate drain connection Condensate drain connector is placed on the rear side of the drain pan, under the evaporator (or CW) coil. Connection diameter is 16 mm for all models. If condensate pump is not present, a PVC pipe with 2 m length is provided. This pipe has to be routed outside the unit through the opening on its base used also for pipes and electric cables.

  • Page 52: Electric Connections

    6.6 Electric connections It is absolutely necessary, before making any connections, to check the supply voltage with a tester. The voltage that is measured must correspond with the voltage indicated on the unit label. The installer must install, upstream from the unit, an isolating switch with fuse and capacity as speci- fied on the label in order to permit maintenance on the machine with total absence of electricity.

    8.3 Refrigerant circuit Refrigerant charge - Quantity and Purity Quantity - Check the sight glass. An unsufficient charge causes the formation of bubbles in the sight glass. An operation with an unsufficient refrigerant quantity over a longer period leads to a reduction of cooling capacity and to high superheating temperatures, which have a disadvantageous effect on the compressor lifetime.
