• Figure 1-2 shows the serial number labels to determine system 1 and 2. There will be stickers with
serial numbers pasted on LVC condensers to identify each system.
• There is a height dierence of the condenser unit due to the dierent heights of individual fan
model.

Note*: - Indicates the condenser is above the indoor unit if the value is positive otherwise the value is negative.
• When the equivalent distance between the indoor unit and the condenser exceeds 30m, refer to Sec-
tion 5.4.2- Refrigerant pipe equivalent length in “Liebert PEX Series Air Conditioner Technical Manu-
al” for the requirement of the equivalent length.
• If the spray cooling module is installed in the condenser, it is advisable to drain-out water before
winter to avoid the frost cracking of spray cooling equipment.
