IMPORTANT INSTALLATION INSTRUCTIONS (Continued)
4. Using the compression fitting, attach the gate valve to the incoming water sup-
ply side pipe. Firmly tighten compression nut. (Figure 4)
IMPORTANT NOTES
It may be necessary to slightly spread pipe ends apart in order to insert the
AP430SS head assembly with adapters into valve.
5. Tighten all compression nuts firmly, keeping the AP430SS head assembly verti-
cal. (Figure 5)
6. Screw cartridge to the right (clockwise) into the AP430SS filter head. Turn on
main water supply, open valves and check for leaks. (Figure 6)
IMPORTANT NOTES
By-Pass Section can be installed around unit if desired using either threaded or
sweated fi tting. (Figure 7)
To reduce the risk associated with property damage due to water leakage:
• Protect from freezing, remove fi lter cartridge when temperatures are
expected to drop below 40°F (4.4°C).
• Ensure all tubing and fi ttings are secure and free of leaks.
• 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.
• Do not install where water hammer conditions may occur. If water ham-
mer conditions exist you must install a water hammer arrester. Contact a
plumbing professional if you are uncertain how to check for this condition.
FILTER CARTRIDGE REPLACEMENT INSTRUCTIONS
To reduce the risk associated with property damage due to water leakage:
• The disposable fi lter cartridge MUST be replaced ever 6 months, at the
rated capacity or if a noticeable reduction in fl ow rate occurs.
Always have spare cartridges on hand.
1. Shut off inlet and outlet valves. Open drain on gate valve, installed backwards
at the AP430SS, to relieve pressure in the AP430SS.
2. Unscrew the cartridge (AP431) to the left (counterclockwise) as shown in the
illustration. (Figure 8)
3. Install the new cartridge, moderately hand tight. Never use tools to tighten a
cartridge.
4. Turn on inlet valve and bleed air through gate valve drain until water appears.
Then close drain, and open outlet valve.
