NOTICE
- Where a backflow prevention device is installed on a water system, a device for controlling pressure due to thermal expansion must be installed. Contact a plumbing professional if you are uncertain how to select/install/maintain a thermal expansion device.
- Where a booster pump is installed on a water system, you must maintain and inspect the attached pressure switch regularly in accordance with the booster pump manufacturer’s instructions. Contact a plumbing professional if you are uncertain how to maintain your booster pump system.
- Where a booster pump is installed on a water system, you must install an appropriate pressure relief valve. Pressure relief valve must be maintained and inspected every 6 months. Contact a plumbing professional if you are uncertain how select/install/maintain a pressure relief valve.
- Where a booster pump is installed on a water system, you must install an appropriate pressure regulating valve and regulate water pressure to <80psi. Contact a plumbing professional if you are uncertain how select/install/maintain a pressure regulating valve.
To reduce the risk of water leakage of flooding, and to ensure optimal filter performance:
- Change the disposable filter cartridge every 6 months or sooner if you observe a noticeable reduction in water fl ow rate.
- Failure to replace the disposable filter cartridge at recommended intervals may lead to reduced filter performance and cracks in the filter housing, causing water leakage or flooding.
- For questions or concerns, please contact Customer Service at 1-800-222-7880.
IMPORTANT NOTES
- Failure to follow instructions will void warranty.
- Allow a minimum of 2” (5.1 cm) clear space under filter to facilitate cartridge change.

GETTING STARTED
Tools and Parts Required
(not included):
- One 3/4” Stop & Waste Valve (Compression Type)
- PTFE Tape
- Two 3/4” Male x 3/4” Street Adapters
- One 3/4” Compression Gate Valve 5) Pipe Cutter
Identify all parts as shown in diagram. Read all instructions carefully before attempting to start installation. The existing shut-off valve remains in place and still acts as the cold water shut-off.
This filter system has 3/4” connections. The AP430SS can be adapted to various pipe sizes by using reducing adapter on either end. Installation fittings can be sweated or threaded. Use galvanized fittings for installation on galvanized pipe.
IMPORTANT NOTES
- Allow a minimum of 2” (5.1 cm) clear space under filter to facilitate cartridge change.
IMPORTANT INSTALLATION INSTRUCTIONS
Before starting, shut off main water supply and drain pipes.
Shut off fuel or electric power supply to water heater after water is shut off.
-
Using PTFE tape, wrap the threaded ends of the adapters and screw into both ends of the cartridge head. Do not use pipe sealant/dope as they may contain solvents that may deteriorate fittings. (Figure 1)
Position the flow direction arrow on the filter head for proper orientation. The arrow on the filter head should be pointing toward the water heater. -
Loosely fit compression fittings onto the cartridge head with adapters. Holding the cartridge head with attached adapters up to the pipe, mark for length of pipe to be removed. Using a pipe cutter, cut pipe. (Figure 2)
-
Using the valve compression fitting, attach the stop and waste valve on pipe (before the system on the cold water side) to the water heater, with indicator arrow pointing towards the AP430SS assembly, so that drain nut can be accessed to release pressure when changing cartridge. Be sure the drain nut is firmly tightened. (Figure 3)
