95. How to activate the cooler? What issues should be noted?
Open the cold medium exhaust valve – open the cold medium inlet valve – (after exhausting) close the exhaust valve, open the cold medium outlet valve – open the hot medium outlet drain valve – open the hot medium inlet valve – (after exhausting) close the exhaust valve, open the hot medium outlet valve – check for leaks
So it should have been that the cooler passed the pressure test from the start: lol
So what counts as the standard?

First, start the cold flow by opening the cooling water inlet valve; at the same time, open the cooling water outlet drain valve to release air, then close the drain valve. Once the tank is filled with water, slowly open the cold flow outlet valve. 3. Re-apply heat flow: Open the heat inlet valve and the outlet drain valve to remove air from the equipment, then close the drain valve and open the outlet valve. Please check the following: 1. Check for leaks in the floating head, cover, flanges, etc. 2. Check for internal leakage in the tube and shell sides

However, maintenance (opening, cleaning, sealing leaks, removing tube bundles, etc.) is not carried out every time before restarting operation; it is also possible that other issues are addressed first, and then the system is brought back online. So pressure testing is not a necessary part of the answer to your question. The issues primarily relate to the contents of operating procedures (procedures), and do not involve the contents of maintenance procedures.
