Troubleshooting

Screws on the indoor fan and

exhaust fan are not loose or

distorted.

Tighten the screws using a 10#

socket wrench.

Water

pump

The water pump is not

rusted.

Remove the rust.

No water leaks from the

water pump spindle seal.

If water leaks, replace the water

pump or water pump spindle seal.

Water

sampling

During the first half year of

operation, take a sample

from each route of supplied

water and from circulating

water for one of units for

each computer room every

month.

NOTICE

Spray water can be circulated

for six times by default, which

can be changed depending on

the local climate and water

source conditions.

If the test result does not the

water quality requirements,

perform a test again and increase

the test frequency (it is

recommended that sampling be

conducted half a month). If the

results of three consecutive tests

do not the requirements, find out

the cause in water supply and take

corresponding measures to ensure

normal operation of the spray

system.
