Symptom
Water accumulates on the floor near air conditioners.
Possible Cause
Air conditioners are not leveled.
Condensate pipes of the air conditioners are blocked.
The drainpipes leak.
The thermal insulation layers on the pipes are damaged.
The thickness of the thermal insulation layers does not meet the minimum requirement.
The charging pipe of the humidifier leaks.
The condensate pump is faulty.
Air conditioners blow moist air or condensation.
Procedure
Step 1 Check whether the air conditioners are leveled.
If yes, go to Step 2.
If no, level the air conditioners by following the air conditioner installation guide and
check whether the fault persists.
− If the fault is rectified, no further action is required.
− If the fault persists, go to Step 2.
Step 2 Check whether the thermal insulation layers on the pipes are intact.
If yes, go to Step 3.
If no, wrap the thermal insulation cotton again and check whether the fault persists.
− If the fault is rectified, no further action is required.
− If the fault persists, go to Step 3.
Step 3 Check whether the charging pipe of the humidifier leaks.
If yes, replace it and check whether the fault persists.
− If the fault is rectified, no further action is required.
− If the fault persists, go to Step 4.
If no, go to Step 4.
Step 4 Check whether the condensate water pipes are blocked.
If yes, clean them and check whether the fault persists.
− If the fault is rectified, no further action is required.
− If the fault persists, go to Step 5.
If no, go to Step 5.
Step 5 Check whether the drainage loop leaks.
If yes, replace the drainpipe and check whether the fault persists.
− If the fault is rectified, no further action is required.
− If the fault persists, go to Step 6.
If no, go to Step 6.
Step 6 Check whether the condensate water pump is damaged.
If yes, replace it and check whether the fault persists.
− If the fault is rectified, no further action is required.
− If the fault persists, go to Step 7.
If no, go to Step 7.
Step 7 Check whether the air conditioners blow moist air and whether condensate remains on the air
exhaust vents.
