Filter
A 1-micrometer filter is recommended for optimal long-term performance of the
HP MCS G2. A cartridge or bag filter could be used in a full-flow or side-stream
flow configuration, with Watts FM4X1-1 stainless steel housing with 1-inch male
connections or equivalent. Provide dielectric unions on both connections. Provide
pleated cartridge rated for 1 micrometer. Depending on the water quality, multiple
units in parallel may be required.

Typical plumbing installation guidelines
The installation service for the HP MCS G2 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 installation.
Contractors shall furnish and install Armacell AP/Armaflex closed-cell elastomeric thermal insulation
with minimum 25 mm (1 in.) wall thickness on all customer piping and fittings. Contractors shall
furnish and install similar insulation type with minimum 6.4 mm (¼ in.) wall thickness for HP MCS
G2 chilled water hoses and fittings. The HP MCS G2 hoses have a 38 mm (1½ in.) outer diameter
and a bolt clamp that is 70 mm (2¾ in.) wide, 51 mm (2 in.), and 45 mm (1¾ in.) deep on the
side that should be connected to the infrastructure pipe. All insulation joints shall be taped with
AP/Armaflex Insulation Tape, 3 mm (1/8 in.) thick x 50 mm (2 in.) wide x 9.1 m (30 ft) long.
Mitered fittings should be cemented with Armaflex 520 Adhesive.
HP MCS G2 condensate and overflow hoses do not require insulation.
Filters may require a minimum of 762 mm (30 in.) clearance under the floor for installation. If the
filters cannot be installed under the floor due to space constraints, they may be placed upstream of
the piping system.
Caution:
It is important that the water supply system feeding the HP MCS G2 is
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
