Replacing Monitoring System Components; Replacing A Polymer T/H Sensor - Huawei FusionModule 1000B Maintenance Manual

FusionModule1000B Air-Cooled IT Solution
Maintenance Guide
Skill requirement: cooling engineer
Procedure
Step 1 (Optional) Use the ESD floor suction plate to open the aisle floor where a condensate
drainpipe needs to be replaced.
Step 2 Remove the water inside the cylinder using a sucker and water container.
Step 3 Remove all fasteners and the thermal insulation foam from the condensate drainpipe.
Step 4 Remove the condensate drainpipe from the precision air conditioner, and block the condensate
drainage port using a rubber plug.
Step 5 Remove the other end of the condensate drainpipe.
Step 6 Take out the rubber plug and install a new condensate drainpipe.
Step 7 Check that the new condensate drainpipe is working properly.
Step 8 After verifying that the condensate drain pipe is working properly, dry the drainpipe using the
dry rag, reinstall condensate pipe fasteners, and wrap the thermal insulation foam.
Step 9 (Optional) Reinstall the aisle floor.

For the diagram, see the quick installation guide for the solution in use.
Wipe off the water with a dry cloth if there is not much water.
Hold the removed drainpipe properly to prevent residual water from flowing out into the container.
If there is no water in the condensate water pan, the condensate drainpipe is working properly.
A Polymer T/H sensor needs to be replaced.
A spare Polymer T/H sensor of the same model is available and functional.
