10.4.1 Opening the Cleaning Windows
The coil is accessible for cleaning through the innovative
cleaning window design (A), allowing you to clean the coil
without removing the fans from the unit.
1. Disconnect the power supply before working on the unit.
2. Remove the cover panels to free the cleaning windows.
3. Loose the mounting screws to open the cleaning windows.
10.4.2 Cleaning
What to use
Plain water Vertiv™ highly recommends to use plain water to clean the coils.
Water pressure from a garden hose and sprayer usually works well.
If the coil has been maintained and cleaned at regular intervals, water is sucient to remove dirt and debris
from the ns.
Brush You may use a brush to remove heavy build up on the exterior of the ns.
