Flushing Schedule & Installation Instructions
Flushing Schedule
The FreshPoint™ is ushed on a schedule dependent on the quality of water being treated.
Default Factory Settings
Flush Frequency: 100 gallons
Flush Duration: 0.5 minutes
Day Override: 1 Day
These settings may need to be adjusted based on the analysis for the water treated and practical experience
with fouling. The FreshPoint™ will automatically initiate a ush if 24 hours (for each 1 day of the Day Override
setting) has elapsed since the last ow initiated ush. This setting is adjusted in the day override setting in master
programming.
A post-ultralter pressure tank is recommended to ensure sufcient ow and pressure to the home during a ush
cycle. The backush surge tank (where installed) will perform the same function.
Refer to Table 1 below for initial set up.

In all cases, a disposable pre-lter cartridge is recommended to protect the FreshPoint™ from large particles,
plumbing debris, etc.

Some shallow wells may have serious contamination problems, hazy water, high TOC, color and high bacterial
loads. The backush kit is recommended to avoid fouling in these installations.
NOTE: It is important to understand the water quality and fouling potential to determine the type of
ushing required when installing the FreshPoint™.
Flow Capacity
Assess the household water use, especially peak water draw. The standard single-element FreshPoint™ is
•
sized for 10 gpm peak capacity ow. Water draw in the house that exceeds peak capacity will have the effect
of reduced pressure and volume delivery at the open taps.
Maximum recommended continuous ow for the FreshPoint™ system is 1.2 gpm for surface water, and 2.9
•
gpm for well water.
Page 6
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 efcient 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, ltrate or outlet, and drain) are 3/4” NPT
•
connections.
A 10 gpm ow control is included to be installed on the inlet of the FreshPoint™ to ensure the membrane
•
operates in an efcient manner.
A 7 gpm ow control is included to be installed on the drain line to maximize water efciency and ensure
•
proper ushing rates are achieved. Ensure the drain selected has the capacity for this ow rate.
Private wells often have higher levels of turbidity or suspended solids that can shorten membrane life without
•
adequate ushing. If fouling potential is high, a backush kit should be installed. The installation of a pressure
tank and solenoid valve switches the system from forward ushing to backushing, thereby extending the
membrane life in high fouling potential waters.
For standard installations, a post-ultralter pressure tank is recommended to maintain pressure during a ush
•
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 ush correctly (120 VAC).
Pretreatment
Pretreatment of the FreshPoint™ with a 200 µm lter is recommended. Some installations may require additional
pretreatment. Reference the Flushing Schedule (Table 1) or the FreshPoint™ Ultraltration 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™ sufciently off the wall to
•
accommodate installation of a pre/post lter 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 backush tank, in the backush kit, requires an additional 16” by 16” of level oor space.
•

Standard Installation (Forward Flush only)
A standard installation clears the membrane periodically by opening a drain port, and allowing the feed stream
ow in its normal direction, but at a faster rate. The ow goes in and out of the end of the ber instead of through
the membrane, and the foulant is cleaned off the membrane and out of the unit to drain.
Connect the FreshPoint™ to the household plumbing supply as shown in Figure 1. It is recommended that the
plumbing include a system bypass for future service. A 200 um sediment pre-lter is recommended. For ease of
membrane element replacement, unions are recommended as indicated on Figure 1.
NOTE: Installations without a pressure tank may experience drops in pressure/ow to the home during a
ush cycle.

Backush Kit Installation
Installations with high fouling potential will require plumbing in a pressurized surge tank and inlet solenoid
valve (See Flushing Schedule Table 1). In the backush mode, the ltered water from a pressure tank ows
backward through the membrane from the ltrate side during the ushing cycle. This removes the foulant from the
membrane surface as well as material that may have entered into the porous structure.
Connect the FreshPoint™ to the plumbing supply as shown in Figure 2. It is recommended that the plumbing
include a system bypass for future servicing, etc. A 200 um sediment pre-lter is recommended. For ease of
membrane element replacement, unions are recommended as indicated on Figure 2. The backush tank should
be installed on a tee before the ow meter. The backush tank precharge pressure should be set to 20 psig.
NOTE: Installation of the backush tank after the meter will cause reverse ow through the meter and
could have a detrimental effect on meter performance.
