Tools and Parts Required
(not included):
1) One 3/4" Stop & Waste Valve (Compression Type)
2) PTFE Tape
3) Two 3/4" Male x 3/4" Street Adapters
4) 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
fi lter 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.
1. 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.
2. 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)
3. 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 indica-
tor 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)
To reduce the risk associated with property damage due to water leakage or
fl ooding:
• Do not install on hot water supply lines. The maximum operating water
temperature of this fi lter system is 100°F (37.8°C).
• Installation and Use MUST comply with all state and local plumbing codes.
• On plastic fi ttings, never use pipe sealant or pipe dope. Use PTFE thread tape
only, pipe dope properties may deteriorate plastic.
• Do not use a torch or other high temperature sources near fi lter system,
cartridges, plastic fi ttings or plastic plumbing.
• 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.
• SHUT OFF FUEL OR ELECTRIC POWER SUPPLY TO WATER HEATER after
water is shut off.
