Note:

The flow should flow in the direction of the red arrows.

Built-in flow meter valve should be set in open position.

Procedure

  1. Switch off the valves on plumbing assembly (handle of valve should be perpendicular to hose pipe. Put the water container under the pipe connector since there will be residual cooling water in it.
  2. Loose hose clamp and remove hose pipe from hose nipple of defect flow meter.
  3. Use wrench A to fix hex connector from tee joint side, and use wrench B to fix hex connector of flow meter. Keep wrench A in original place, then rotate wrench B to remove defect flow meter by anti-clockwise direction turn.
  4. Apply the seal tape on screw thread of tee joint with clockwise direction turn, and then install new flow meter with tee joint together.
  5. Install hose pipe on hose nipple of new flow meter, then tighten pipe by two hose clamps---one clams was tighten by position turn & another clamps was tighten with inversion turn.
  6. After new flow meter replacement, reassemble the plumbing connection and switch on the valves to check whether there is water leak.
  7. Remove the power lock- out tag-out from the System cabinet and restore power. If water leakage observed, re-perform installation from Step 2step 2
