Installation Instructions
Additional Water Treatment Devices
It is preferable to install the FreshPoint™ ahead of softeners and carbon filters, as the removal of particulates
generally improves their performance. The FreshPoint™ should be installed after equipment such as iron filters,
sediment filters, or multimedia filters.
Installation downstream of a chlorinator runs the risk of oxidative attack of the membrane, shortening the membrane
life depending on chlorine level, time of contact and temperature. The FreshPoint™ can withstand a continuous
dose of up to 4.0 mg/L (or ppm) of free chlorine, but continuous exposure to higher level of free chlorine or other
oxidizing chemicals can shorten the life of the membrane.
When installed on a chlorinated water supply of less than 4.0 mg/L free chlorine, it is preferable to allow the chlorine
to pass through the FreshPoint™.
FreshPoint™ Installation Instructions
Tools and Supplies needed:
1.
Teflon
thread tape or paste for leak free assembly of the pipe thread connections.
®
CAUTION: Ensure that the paste is compatible with plastic fittings.
2.
Lubricant for seals (a packet of silicone is supplied)
NOTE: Silicone (supplied) should be applied sparingly to avoid fouling the membrane.
3.
Four ¼" bolts to mount the system to the wall.
4.
½" open end wrench to tighten saddle clamp.
5.
7/16" open end wrench to tighten ¼" wall mount bolts.
6.
Crescent wrench that can open to 1 ½" to grip flow control.
7.
Pipe wrench to grip the vessel's side port.
8.
Flat head screw driver and pliers to remove the vessel's vessel retaining ring.
Unpacking (Refer to Figure 4, FreshPoint™ Assembly)
1.
Open the box with the hardware and verify that all of the components pictured on the FreshPoint™ Assembly page
are present and undamaged.
2.
Open the Plumbing Kit bags, and verify that all of the components listed on the parts list (found in the Plumbing Kit
bags) are present and undamaged.
3.
The membrane is packed in a preservative solution, and should not be opened until it is to be installed in the
housing.
Hardware Assembly (Standard Assembly):
1.
Assembly is most easily done on a horizontal surface.
2.
Position a mounting bracket (Item 4), a saddle, and a saddle clamp (Items 5) about 10" from the top of the vessel
(Item 1). Leave the bolts loose. Note: The smaller diameter portion of the mounting bolt holes in the mounting
bracket must be positioned toward the top of the vessel.
3.
Position the bracket of the timer (Item 6) between the mounting bracket and the saddle clamp. Ensure timer is
oriented correctly.
4.
Rotate the vessel so that the side ports are oriented in the direction compatible with the site plumbing and tighten
the saddle clamp bolts with the ½" wrench.
5.
Install the remaining mounting bracket, saddle, and saddle clamp at a convenient location near the bottom of the
vessel, and tighten the saddle clamp bolts with a ½" wrench.
Vessel Head Removal
1.
Remove the top end closure, bottom end closure, and two square cross section seals from the vessel.
a. Remove the retaining rings by prying the tabbed end out of the stainless steel groove with the tip of the
screwdriver. Once the end of the retaining ring is clear of the groove, grasp the tab with the pliers and pull it toward
the end of the vessel until the end of the ring is resting in the end margin of the shell.
b. Remove the 4" retaining ring from the stainless steel groove in the shell by rotating your finger behind the ring as
it continues to exit the groove.
c. Once the retaining ring has been removed, examine the area for burrs or dings which could damage the head or
membrane. If necessary, use Scotch-Brite® or 600 grade sandpaper to smooth the area.
d. Grasp the adapter and pull the head straight out. A small amount of side-to-side movement may be necessary to
start the head moving.
