WARNING
CAUTION
To reduce the risk associated with property damage due to water leakage:
• Read and follow Use Instructions before installation and use of this system.
• Installation and Use MUST comply with all state and local plumbing codes.
• Protect from freezing, remove fi lter cartridge when temperatures are expected to drop below 40°F (4.4°C).
• Do not install on hot water supply lines. The maximum operating water temperature of this fi lter system is 100˚F (37.8˚C).
• Do not install if water pressure exceeds 125 psi (862 kPa). If your water pressure exceeds 80 psi (552 kPa), you must
install a pressure limiting valve. Contact a plumbing professional if you are uncertain how to check your water pressure.
• Where a backfl ow prevention device is installed on a water system, a device for controlling pressure due to thermal
expansion must be installed.
• Do not install where water hammer conditions may occur. If water hammer conditions exist you must install a water
hammer arrester. Contact a plumbing professional if you are uncertain how to check for this condition.
• Do not use a torch or other high temperature sources near fi lter system, cartridges, plastic fi ttings or plastic plumbing.
• On plastic fi ttings, never use pipe sealant or pipe dope. Use PTFE thread tape only, pipe dope properties may deteriorate
plastic.
• Do not install in direct sunlight or outdoors.
• Do not install near water pipes which will be in path of a drilling tool when selecting the position to mount the bracket.
• Mount fi lter in such a position as to prevent it from being struck by other items used in the area of installation.
• Ensure that the location and fasteners will support the weight of the system.
• Ensure all tubing and fi ttings are secure and free of leaks.
• The disposable fi lter cartridge MUST be replaced every 6 months, at the rated capacity or sooner if a noticeable
reduction in fl ow rate occurs.
IMPORTANT NOTES
• Failure to follow instructions will void warranty.
• Install with the inlet and outlet ports as labeled. Make sure not to reverse connections.

Installing the APIL3R Replacement Water Filter
IMPORTANT NOTE
• Have a bucket and towel ready.
1) Disconnect the old filter at the INLET side first (this shuts off the water) by squeezing the valved fitting and pulling
away from the filter. Do the same for the outlet side.
2) Attach O-Ring fittings to new filter. Be sure to coat threads with PTFE thread tape.
3) With the OUTLET end over a bucket, attach INLET O-ring fitting (water will begin to flow through filter). Flush two
(2) gallons of water through the filter before use (approximately 2.5 minutes). Disconnect INLET fitting to stop water
flow.
4). Connect OUTLET fitting.
5) Connect INLET Fitting. Filter is now ready for use.
6) Write the date on the filter when installed, then mark your calendar with a reminder to replace the filter in 6 (six)
