*The 1μm filter might require a minimum of 762 mm (30 inches) clearance under the floor for installation. If a filter cannot be installed under the roof because of space constraints, it may be installed further upstream in the pipe system.

Typical plumbing installation guidelines

CAUTION: The water supply system feeding the HP Modular Cooling System 200/100 must be capable of withstanding operation with rapid and frequent changes in flow requirements.

•Installation service for this MCS-200/100 is order number UE005E.

•Contractors must install all valves, strainers, and other piping components to the specifications provided in “Piping approaches (on page 51).” All components must be readily accessible.

•Contractor must flush all lines of debris and cap prior to MCS-200/100 installation.

•Contractors must furnish and install Armacell AP/Armaflex closed-cell elastomeric thermal insulation with minimum 25-mm (1-inch) wall thickness on all customer piping and fittings. Contractors shall furnish and install similar insulation type with minimum 6.4-mm (0.25-inch) wall thickness for MCS-200/100 chilled water hoses and fittings. The MCS-200/100 hoses have a 45-mm (1.75-inch) OD and a bolt clamp that is 76 mm (3 inches) wide, 57 mm (2.25 inches) high, and 51 mm (2 inches) deep on the side that must be connected to the infrastructure pipe. All insulation joints must be taped with AP/Armaflex® Insulation Tape, 3 mm (0.125 inch) thick x 50 mm (2 inches) wide x 9.1 m (30 ft) long. Mitered fittings must be cemented with Armaflex® 520 Adhesive.

•MCS-200/100 condensate and overflow hoses do not require insulation.

•Filters might require a minimum of a 762-mm (30-inches) clearance under the floor for installation. If the filters cannot be installed under the floor due to space constraints, they can be placed upstream of the piping system.

HP recommends that the MCS-200/100 Hook Up Kit (BW971A) be ordered for each MCS-200/100 installed.

The water supply system feeding the MCS-200/100 must capable of withstanding the following situations:

•Deadheading—operating with a closed line

•Operation with rapid and frequent changes in flow requirements

•Operation over long periods with zero water flow
