Installation Instructions
Plumbing
The system and installation piping should be cleaned before the system is started so that no impurities,
abrasive materials, or oily materials are washed into the membranes. The piping must be purged of air to
prevent water hammer which can damage the system.
A bypass system is strongly to permit the most efficient service of the FreshPoint™ over its life. Additionally,
some local plumbing codes may require a bypass.
All three FreshPoint™ housing ports on the system (inlet, filtrate or outlet, and drain) are 3/4” NPT
connections.
A 10 gpm flow control is included to be installed on the inlet of the FreshPoint™ to ensure the membrane
operates in an efficient manner.
A 7 gpm flow control is included to be installed on the drain line to maximize water efficiency and ensure
proper flushing rates are achieved. Ensure the drain selected has the capacity for this flow rate.
Private wells often have higher levels of turbidity or suspended solids that can shorten membrane life without
adequate flushing. If fouling potential is high, a backflush kit should be installed. The installation of a pressure
tank and solenoid valve switches the system from forward flushing to backflushing, thereby extending the
membrane life in high fouling potential waters.
For standard installations, a post-ultrafilter pressure tank is recommended to maintain pressure during a flush
cycle.
The system must be protected from possible back contamination by the installation of an air gap between the
FreshPoint™ drain connection and the drain line.
Electrical Requirements
The FreshPoint™ controller requires a constant electrical supply to flush correctly (120 VAC).
Pretreatment
Pretreatment of the FreshPoint™ with a 200 µm filter is recommended. Some installations may require additional
pretreatment. Reference the Flushing Schedule (Table 1) or the FreshPoint™ Ultrafiltration Systems Applications
Guide for more information.
FreshPoint™ Location
Note the location of the water supply, drain and an electrical outlet when choosing a mounting location.
The FreshPoint™ is a point-of-entry (POE) device designed to treat water distributed throughout the entire
plumbing system. The installation should be located near the point of entry, but ahead of where plumbing
splits for distribution.
The system mounting bracket has been designed to mount the FreshPoint™ sufficiently off the wall to
accommodate installation of a pre/post filter inline with the water inlet and/or water outlet of the system.
Remember to allow for visual and physical access to the meter/programming controls.
Do not mount the FreshPoint™ above any electrical equipment, or above items that may become damaged if
they get wet.
Install the FreshPoint™ in a location that will allow for easy service access. Service and maintenance requires
access to the unit and removal and replacement of the membrane element.
Mount the FreshPoint™ to a wall in a vertical orientation using appropriate mounting hardware (not included)
capable of supporting 51 pounds (23.1 kilograms).
The FreshPoint™’s footprint is 12” x 12”, exclusive of plumbing connections. The FreshPoint™ requires 85”
of vertical room to allow for removal of the membrane, unless plumbing accommodations are made (e.g.:
unions). See Figure 3 for a typical installation with dimensions.
The backflush tank, in the backflush kit, requires an additional 16” by 16” of level floor space.
Plumbing Options
There are two options for plumbing in the FreshPoint™ system:
Standard Installation (Forward Flush only)
Backflush Kit Installation
