Aqua-Pure AP430SS - Manual (Page 5)

4. Using the valve compression fitting, attach the gate valve to the incoming water
supply pipe after the system. Firmly tighten compression nut. (Figure 4)
5. Tighten all compression nuts firmly, keeping the AP430SS head assembly verti-
cal. (Figure 5)
6. Screw cartridge to the right into the AP430SS filter head. Turn on main water
supply, open valves and check for leaks. (Figure 6)
IMPORTANT INSTALLATION INSTRUCTIONS (Continued)
It may be necessary to slightly spread pipe ends apart in order to insert the
AP430SS head assembly with adapters into valve.
IMPORTANT NOTES
Optional: By-Pass Section can be installed around unit if desired using either
threaded or sweated fi tting. (Figure 7)

CARTRIDGE REPLACEMENT INSTRUCTIONS
CAUTION
To reduce the risk associated with property damage due to water leakage:
• The disposable cartridge MUST be replaced ever 6 months or sooner.
Figure 8
Always have spare cartridges on hand.
1. Shut off inlet (Stop and Waste) and outlet (Compression Gate) valves. Open
drain on inlet valve, to relieve pressure in the AP430SS.
2. Unscrew the cartridge (AP431) to the left 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.
CAUTION
To reduce the risk associated with property damage due to water leakage:
• Protect from freezing, remove 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.
