Specifications
Watts Pure Water Series PWM Micro Z™ filter system shall
be installed on the building’s main water line just after it enters
the building. The installation point shall be after any backflow
prevention or pressure regulating valves. Other installation
options are to install a system just before the plumbing equip-
ment needing the protection of filtered water. In installations
where the dedicated cold water make up to a water heater is
the installation point, a backflow preventer and a thermal expan-
sion tank must be installed as well. The system shall be installed
with a bypass valve to allow for the shut down and removal of
the unit without interrupting the water supply to the building.
The filter system shall be a backwashing granular media bed
type with digital programmable time clock initiated backwash,
high-capacity alumino-silicate filter media rated for 3-5 nominal
particle size removal, and all components necessary for proper
operation. Electrical requirements are 120 volt 60 hertz. A local
drain is required to accept drain water from the system. The
feed water pressure must not fall below 30psi (207 kPa) or
exceed 125psi (8.7 bar). Water temperature must not fall below
34°F or exceed 110°F (1 - 43°C).
The system shall provide water that has been filtered to a nomi-
nal micron rating of 3-5 micron.
