Water Leakage Detector; Water Balance - Tripp-Lite SRCOOL60KCW El Manual Del Propietario

4. Initial Startup

4.5 Water Leakage Detector

This cooling unit contains a connection for the SRCOOL60KDR water leakage detector (sold separately) at the bottom of the cabinet.
When installed, the water leakage detector will be triggered to issue an alarm when in contact with water or liquid, alerting you to
take proper measures. You must manually set the detector for leakage detection on-site and in a low-lying place. If the lower piping
configuration is adopted, it is suggested to set it close to the pipeline below the raised floor.
Pass one end of the water leakage detector through the small hole at the lower part of the cabinet and set the detector at the above-
mentioned place.

4.6 Water Balance

The program adopts a compensation method and adjusts the flow rate with the first (most remote) cooling unit as a reference point. The
process involves at least three assistants. Maintaining communication via handheld communication devices is suggested. The number of
cooling units in a circuit varies. For the following steps, a six-unit configuration is used as an example.
1
Set a balance valve at the return water end of the main pipe to adjust the total flow rate of the circuit.
2
Use the control panel to set all cooling units in installation mode (see 4.4 Operating Temperature and Humidity). The three-way
ball valves will automatically open completely (100%).
3
Fully open the balance valve of the return water end and the branch balance valves at all branches. Record the flow rate of each
unit.
4
Adjust the balance valve of the return water end to 110% of the rated total flow rate. If the balance valve cannot reach this value
when fully opened, keep it at full opening and adjust the flow rate of each branch proportionally.
5
Fully open the branch balance valve of Unit 1. Then adjust the balance valve of the return water end of the main pipe circuit to
enable Unit 1 to reach its rated flow rate (±5%). Make sure once again its branch balance valve is kept fully open.
