NOTICE
Risk of clogged or leaking drain lines. Can cause equipment and building damage.
This unit requires a water drain connection. Drain lines must be inspected regularly and
maintenance must be performed to ensure that drain water runs freely through the drain
system and that lines are clear and free of obstructions and in good condition with no visible
sign of damage or leaks. This unit may also require an external water supply to operate.
Improper installation, application and service practices can result in water leakage from the
unit. Water leakage can result in severe property damage and loss of critical data center
equipment.
Do not locate unit directly above any equipment that could sustain water damage.
Vertiv recommends installing monitored leak detection equipment for the unit and the supply
and return lines.
