Configure an external pipeline and an automatic exhaust valve
the pipeline. Set a Y-type filter
3 in front of or behind the Y-type filter to set up a branch circuit. When the filter needs cleaning or maintenance, close the ball valve to
let the chilled water go to the cooling unit via the branch to avoid shut-off loss. Install a pressure meter
filter and determine if there is a blockage according to the pressure difference.
Configure a multi-function balance valve
Pipeline flushing
To guarantee cooling efficiency, you must flush the pipeline to filter out impurities and chemical substances. For pipeline flushing, use a
hose to create a short circuit so the chilled water goes directly from the inlet end to the return end without passing through the cooling
unit. Use a fine-meshed filter (20-mesh suggested) in the Y-type filter to filter out the fine impurities. After 12 to 24 hours of water
circulation in the pipeline, change to a larger-meshed filter (3-mesh suggested).
When using a glycol additive, refer to Appendix 3: Glycol Correction Table for information about cooling capacity and water-side
pressure drop.
