Page 5: Safety
1 Safety Intended Use The nVent SCHROFF cooling modules described in this manual are intended to be installed into the 19" plane of electronics cabinets to provide heat dissipation. The cabinet with the cooling module forms a closed system and allows the cooling of electronic components mounted in its 19"... -
Page 6: Safety Symbols Used In This Manual
Safety symbols used in this manual In these original operating instructions, warning notices point out residual risks that cannot be avoided by constructive means when installing or operating the cooling module. The warning notices are classified according to the severity of the damage occurring and the probability of its occurrence. -
Page 7: Safety Information For The Operator
1.4.1 General notes The operator must comply with all relevant safety regulations for setting up and operating the nVent SCHROFF LHX+ cooling modules, e.g. accident prevention regulations for the operation of cooling equipment. Furthermore, the installation and connection conditions and the corresponding instructions in Chapter 3 Transport and installation must be observed. -
Page 8: Cooling Modules Overview
2 Cooling modules overview The nVent SCHROFF cooling modules 29714-0xx are intended to be installed at the bottom of the 19" plane in closed electronics cabinets. The following variants are available at the time of the compilation of this manual: Part-No. -
Page 9: Functional Description
Functional description The cooling system consists of an air loop and a water loop. The fans of the cooling unit draw warm air from the rear section of the cabinet and into an air/water heat exchanger. The air is cooled down and then blown into the front area of the cabinet. -
Page 10: Transport And Assembly
3 Transport and assembly Safety rules for transport and assembly ⚠ WARNING Risk of accidents due to insufficiently qualified personnel! The installation may only be carried out by qualified personnel who are authorized to do so according to the valid safety regulations, e.g. -
Page 11: Installation
Installation ATTENTION Use heavy-duty slide rails! The cooling unit must only be mounted on heavy-duty slide rails with a load capacity of 25 kg. If the cooling module is mounted only on the 19" rack mounting brackets, the cooling module will be damaged; water may leak out and damage the electronic components in the cabinet. -
Page 12: Connection To The Cooling Water Supply
3.3.2 Connection to the cooling water supply ATTENTION Outflow of cooling water can cause damage! Connection to the cooling water supply should be carried out by a refrigeration engineer or suitably trained plumber. It must be ensured that suitable structural measures (leak sensor, automatic shut- off valves) prevent damage to surrounding components in the event of a leak or defect. -
Page 13: Requirements For The Water Quality
3.3.3 Requirements for the water quality ATTENTION Risk of corrosion! If aluminum is used in the external water circuit, there is a risk of corrosion. To avoid electrochemical corrosion, the compatibility of the materials used in the cooling module with those of the external cooling circuit must be observed. ... -
Page 14: Water Connection
3.3.4 Water connection ATTENTION Damage due to condensation and spraying water! The cabinet doors must be closed for operation. If the cooling module is operated in an open cabinet, condensation water will be produced around the heat exchanger, which is distributed by the fans in the enclosure and can damage the electronics components. - Page 15 Installation must be carried out by a qualified plumber. Corresponding connection kits are available as accessories. The bottom of the cooling module is designed as a condensate tray with a 10 mm hose connection at the rear side. Especially at low water inlet temperatures it is recommended to realize the condensate drain on site via the hose connection.

Electrical rating (Example) Verify that your mains voltage corresponds with the product's electrical ratings label. Currently available are the following cooling modules: 29714-016 - Mains Voltage 200 – 240 VAC 29714-017 - Mains Voltage 200 – 240 VAC Date: 2021/04/13... -
Page 17: Mains Input
3.3.6 Mains input The cooling unit provides a fused mains/line input with IEC60320-C14 connector at the rear side. Fuse Ground Stud (M6) IEC60320-C14 connector Fuse rating (Example) Connector for fan control and monitoring 3.3.7 Fan control and monitoring The cooling module has no internal fan controller. For fan control and monitoring, an external controller is needed to set the fan speed on a fixed level or to adjust it depending on the differential pressure. -
Page 18: Fan Replacement
Fan replacement Fehler! Verweisquelle konnte nicht gefunden werden. The cooling module must be switched off before removing the fan. If this is not done automatically, e.g. by the door contact switch, please unplug the power plug. Steps Press down the lever (1) ... -
