Typical plumbing installation guidelines

• Installation service for this MCS 5042 is order number UE005E.

• Contractors shall install all valves, strainers, and other piping components to the specifications

provided in the Chapter 2 section “Piping approaches.” All components shall be readily accessible.

• Contractor shall flush all lines of debris and cap prior to MCS 5042 installation.

• Contractors shall furnish and install Armacell AP/Armaflex® closed-cell elastomeric thermal

insulation with minimum 25 mm (1 inch) minimum 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 5042 chilled water hoses and fittings. The MCS 5042 hoses have a 45 mm

(1.75 inch) outer diameter and a bolt clamp that is 76 mm (3 inches) wide, 57 mm (2.25inches)

high and 51 mm (2 inches) deep on the side that must be connected to the infrastructure pipe. All

insulation joints shall be taped with AP/Armaflex® Insulation Tape, 3 mm (1/8 inch) thick x 50 mm

(2 inches) wide x 9.1 m (30 feet) long. Mitered fittings must be cemented with Armaflex® 520

Adhesive.

• HP MCS 5042 condensate and overflow hoses do not require insulation.

• Filters might require a minimum of 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.

Caution:

The water supply system feeding the MCS 5042 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 of time with zero water flow.
