Allowed Value
Water pipe diameter
DN25
a: If σ
20
is less than 300 μS/cm, it takes a longer time for the humidifier to generate
vapor for the first time. If σ
20
is greater than 1250 μS/cm, the humidifier service life is
affected.
b: If the water hardness exceeds 100 mg/L (CaCO
3
), a water softener should be
installed.
Step 6
Check the pipe connections of the air-cooled precision smart cooling products. Verify that the
secondary refrigerant circulation pipeline, secondary refrigerant water refill pipeline,
humidifier water refill pipeline, and condensate drainpipe are installed as required, and that
the thermal insulation layer is intact.
Step 7
Verify that the required amount of refrigerant is injected into the cooling system.
Step 8
Check the auxiliary water refill devices, and verify that water refill to the humidifier is
normal.
Step 9
Verify that the condensate drainpipe is not blocked.
Step 10
Check the FusionModule1000 aisle containment, and verify that the doors, floors, and ceilings
are properly sealed.
