Vertiv CoolChip CDU 600 - General

Commercial grade coolant fluid is generally less corrosive to the common metals of construction than water
itself. It will, however, assume the corrosivity of the coolant fluid from which it is prepared and may become
increasingly corrosive with use if not properly inhibited.
Vertiv recommends installing a monitored fluid-detection system that is wired to activate the automatic closure
of field installed coolant fluid supply and return shut off valves to reduce the amount of coolant fluid leakage and
consequential equipment and building damage. The shut off valves must be sized to close off against the
maximum coolant fluid system pressure in case of a catastrophic fluid leak.
NOTICE
Risk of a catastrophic water circuit rupture. Can cause expensive building and equipment damage.
The overflow drain pan should have a drain line connected to it that flows to a floor drain or maintenance sink in
case of a shutoff valve or leak detection system malfunction.
NOTICE
Risk of passageway interference. Can cause unit and/or structure damage. The unit may be too large to fit
through a passageway while on or off the skid. Measure the unit and passageway dimensions, and refer to the
installation plans prior to moving the unit to verify clearances.
NOTICE
Risk of damage from forklift. Can cause unit damage. Keep tines of the forklift level and at a height suitable to fit
below the skid and/or unit to prevent exterior and/or underside damage.
NOTICE
Risk of improper storage. Can cause unit damage.
Keep the unit upright, indoors and protected from dampness, freezing temperatures and contact damage.
NOTICE
Risk of improper control circuits. Can cause equipment damage.
When using jumpers for troubleshooting, always remove jumpers when maintenance is complete. Jumpers left
connected could override controls and cause equipment damage.
1.1 General
Mechanical and electrical equipment such as coolant distribution units (CDUs) present potential mechanical and electrical
hazards. Adhere to all safety, installation, operation, and maintenance instructions. Any work on or use of the equipment
should be carried out and/or supervised by personnel trained and qualified to work on this type of equipment by Vertiv. This
product is designed to minimize all potential hazards by restricting access through unit casings, doors and covers while
equipment is operational. Before performing any maintenance work, ensure the following:
1. Equipment is shut OFF.
2. Equipment and controls are disconnected from the electrical supply.
3. All rotating parts such as pumps and three-way valves have come to a rest.
If in doubt regarding safety, installation, operation or maintenance instructions, consult the manufacturer for clarification and
advice.
