When to call the Dealer
If problems are experienced with the installation or operation of the FreshPoint™, refer to the troubleshooting
guide in this service manual, or contact your FreshPoint™ Distributor for assistance.
Monitoring
If changes to the flow rate or pressure are noticed, contact the installer to get recommendations on changing
flushing settings, and/or have the system evaluated by the installer. Many factors can cause a change in pressure.
As water temperature decreases, the flow available from the FreshPoint™ system will also decrease for the
same inlet pressure. The flow rate will drop or rise approximately 3% for a corresponding 1° (1.8°F) drop or rise
in water temperature. Prefilter plugging will cause a decrease in available pressure. Additionally, if a noticeable
loss of pressure is detected over time, the current flushing schedule may not be sufficient to prevent fouling, and
additional flushing will be required. Refer to the Troubleshooting section in this service manual to address this and
other issues.
Prefilter Changes
The prefilter should be changed as recommended by the manufacturer. Generally, change the cartridge when a
decrease in pressure is noted, or after 6 months installed.
Membrane Maintenance
The FreshPoint™ membrane must be kept in a wetted condition. Once installed or during service and
maintenance activities, do not allow the FreshPoint™ membrane to sit completely drained for extended periods
(greater than 12 hours). Failure to do so may damage the system. If the FreshPoint™ is drained or out of
service for an extended period of time, the installer/dealer should put a preservative into the system to keep
the membrane wetted and prevent microbial growth. A 0.1% sodium bisulfite solution is recommended. A 0.1%
sodium bisulfite solution would be 1 gram of sodium bisulfite added to one liter of water (approximately ten liters
are required).
Prior to putting the FreshPoint™ back into service, the system should be flushed and sanitized per the
instructions in the Installation section of this service manual.
Membrane Cleaning
Membrane cleaning is required when the surface of the membrane and membrane pores become fouled. This
is most often detected by a loss of flow rate. The FreshPoint™ membranes should be maintained in a clean
condition, unfouled by particulate matter, precipitates or biological growth. Contact your FreshPoint™ Distributor
for cleaning.
