Whole House Installation
(
1/2 inch or 3/4-inch main cold water line)
Materials Required:
(2) 3/4-inch or 1/2-inch NPT compression fittings
Teflon
®
tape
Reducing adapters (if necessary)
NOTE:
• Reducing adapters can be used to adapt the filter to different pipe sizes. See your local
hardware store or plumbing store for help in selecting the necessary adapters and com-
pression fittings for your installation needs.
• Galvanized fittings must be used with installation on galvanized pipe.
• Filter must be installed after water meter or pressure tank.
1. Turn off cold water supply and open nearest faucet to drain pipes before starting instal-
lation. Wrap about 6 inches of Teflon
®
tape in clockwise direction around pipe threads
of each compression fitting.
2. If mounting bracket (not supplied) is to be used, first use bracket as a template to mark
screw locations. Then place bracket over cap and align with inlet and outlet ports. Allow
1-
1
/
2
inch clearance below housing to enable cartridge changes.
NOTE: Mounting bracket for heavy-duty filter does not fit over inlet/outlet connec-
tions. Heavy-duty bracket should be screwed directly into cap or filter.
3. Start compression fittings into cap by hand and use a wrench to tighten firmly. DO NOT
OVERTIGHTEN. About one thread should remain visible. Remove compression nuts from
fittings.
4. Measure length (shown as X on Figure 4) across assembled fittings and subtract 1 inch
if you are installing on 3/4-inch pipe or 1
1
/
2
inches if you are installing on 1/2-inch pipe.
Mark section of pipe to be removed.
5. Use a pipe cutter or hacksaw, cut pipe and remove marked section of pipe. File or sand
sharp edges on remaining pipe.
6. Slip compression nut and ferrule onto each end of pipe.
7. Align filter assembly with ends of pipe, making certain cap opening marked “IN” is fac-
ing your incoming water supply. It will be necessary to spread ends of pipe apart to
install filter assembly. Using two adjustable wrenches, hold incoming adapter securely
with one wrench and tighten nut with second wrench. Repeat process for outgoing
adapter.
8. Slowly turn on the water supply to allow filter to fill with water, then press the red pres-
sure-relief button on top of filter to release trapped air. Open nearest faucet and flush
water through cartridge for 5 minutes. Check for leaks before leaving installation.
9. CAUTION: If water pipes are used to ground electrical systems, appliances, or
phones, be certain to install a jumper wire. Contact a qualified electrician with any
questions about your home’s electrical system.
