Vertiv SmartCabinet - 2.3.3. Connection of the Copper pipes

Vertiv | SmartCabinet | User Manual 32
System Installation
• Preparing a base to bear the weight of the outdoor unit is important where the base should be at least
50mm higher than the ground and 50mm wider than the outdoor unit base.
• The outdoor unit is around 43 kg; therefore, utmost care must be taken while removing it from the
cabinet and placing it at the top of the cabinet; any mishandling will result in severe injury and damage to
the equipment.
• The AC is an industry-grade device, used in the SmartCabinet system and is not sold separately meaning
it is inclusive with the SmartCabinet package. Its total rated power is higher than 1 kW, in compliance with
the IEC61000-3-2 standard.
2.3.3. Connection of the Copper pipes
In this section, the general principles of connecting copper pipes, installation information about the
connectors and the required pipe connections will be explained in detail.
General Principles
• Copper pipes with quick thread connectors must be used to connect the indoor and outdoor unit. If the
pipe length exceeds the standard pipe length and a straight copper pipe is used, in that case, piping joints
must be brazed.
Refer Table 2-7 shows the vertical distance between the indoor and the outdoor unit.
Table 2-7
Relative position Value
Outdoor unit installed higher than the indoor unit Maximum: 15m
Outdoor unit installed lower than the indoor unit Maximum: 5m
• Follow standard industry practices in selection and placement of pipes, system evacuation, and charging
with refrigerant (only when the pipeline is long). The standard refrigerant of the AC unit is R410A and the
charging amount is 1.2 Kg.
• Carefully, consider both the pressure drop in the pipeline and the oil returnd to the compressor to avoid oil
leakage and clogging in parts of the system. It also minimizes the noise and vibration signicantly.
• Consult Vertiv Co. if an extended piping kit is required or if the equivalent length exceeds 20m. Also,
consult Vertiv Co. if the vertical distance between the indoor unit and outdoor unit exceeds the values
mentioned in the Table 2-7.
• The equivalent length of each part is shown in the Table 2-8. It is necessary to consider factors such as
loss of resistance due to elbows and valves. The technician or engineer installing the unit must conrm if
the values are appropriate in accordance with the site conditions.
