3 Routine Maintenance
3.1 Pre-fab. Module Repainting
Prerequisites
● Before repainting, communicate with the customer and inform the customer
that the front, left, and right surfaces of the data center exterior are level A
surfaces, and rear, bottom, and top surfaces are level B surfaces.
– The color may be slightly
dierent when level A surfaces are repainted.
Reach an agreement with the customer before repainting.
– Acceptance criteria for repainting of level B surfaces: The repainted area
should have the same color as surrounding areas. The color
dierence ΔE
is not greater than 3. (Use a colorimeter to measure the color
dierence.
If a colorimeter is not available, check that no obvious edge exists
between the repainted area and its surrounding.) The paint should also
be free from bulges, scratches,
ake-o, or cracks.
● The outdoor area without shelters is not subject to bad weather conditions
such as raining, sandstorm, strong wind, or snowing during paint repair.
● You have prepared the required paint that matches the color palette delivered
with equipment.
