thermal expansion must be installed.
• 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.
• Take care when using pliers or pipe wrenches to tighten plastic fi ttings, as damage may occur if overtightening
occurs.
• Do not install in direct sunlight or outdoors.
• 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 ever 6 months, at the rated capacity or if a noticeable reduction in fl ow rate occurs.
IMPORTANT NOTES
• Failure to follow instructions will void warranty.
• Allow a minimum of 3” (7.6 cm) clear space under fi lter to facilitate cartridge change.
• Install with the inlet and outlet ports as labeled. Make sure not to reverse connections.
• Do not crimp copper tubing.

GETTING STARTED
Your new Aqua-Pure® AP510 Full Flow Drinking Water System will reduce chlorine tastes and odors, particulate and
scale from your drinking water. The filter installs under the sink on the cold water line and uses the existing faucet. The
AP510 features its own automatic shut-off, thereby eliminating the need for any external valves. The installation procedure covered in this manual requires the removal of a section of the cold water tube. Soft copper tubing and compression fittings should be purchased locally to complete the installation.

IMPORTANT INSTALLATION INSTRUCTIONS
1. Position the filter by holding it against the right hand side of the cabinet wall
underneath the sink. Allow at least 3” (7.6 cm) beneath the filter to install cartridge. Determine a desirable location for the filter installation and inlet connection. Attach the mounting bracket to appropriate mounting bosses on filter head
with the self-tapping screws supplied. (Figure 1)
2. For installation using machine screws and nuts, remove drawer from adjacent
cabinet and drill two 7/32” diameter holes through cabinet wall. Fasten filter
bracket to wall with screws, nuts and washers. Use washers on both sides of the
wall. Mounting to the cabinet side wall gives the filter good, rigid support. (Figure
2) For installation using sheet metal screws, simply prick punch at marked location (Step 1), position bracket in place, and install screws with screwdriver.
WARNING
To reduce the risk associated with a hazardous voltage due to an installer drilling through existing electric wiring or water pipes in the area of installation:
• Do not install near electric wiring or piping which may be in the path of a
drilling tool when selecting the position to mount the fi lter bracket.

IMPORTANT INSTALLATION INSTRUCTIONS (Continued)
3. Wrap a 3” (7.6 cm)
long piece of PTFE tape
to the right (clockwise)
around the 3/8” MNTP
threads of the fittings.
Wrap tightly so that
it conforms to the
threads of the fitting
and overlaps about
1/2”. (Figure 3) Do
not wrap 3/8” or 1/2”
compression threads
with tape.
4. Screw one fitting
into the filter outlet
and the other fitting
into the filter inlet
(both are labeled on
filter head assembly.)
Tighten both fittings
with a wrench. Do
not overtighten.
Overtightening may
result in a cartridge
crack which may
lead to fluid leaking
(Figure 4)
5. Remove the two
screws at top of head
assembly. Position
either inlet fitting or
outlet fitting through
large hole in bracket
and replace these two
screws. Filter head
is now mounted and
ready for plumbing.
(Figure 5)
6. Measure down from
filter inlet fitting about
1” (3 cm) and mark
existing cold water
tubing. From this
mark, measure up
8” (20 cm) and mark
tubing. This is the
section of tubing to
be removed. If necessary, because of tight
situations, additional
tubing may be cut
away. (Figure 6)

7. Turn off cold water
supply valve and open
cold water tap to
relieve system pressure. Cut cold water
tubing using a tube
cutter or razor knife.
Do not use a hacksaw,
etc. Place a pan under
it to catch any water
present. (Figure 7)
8. Two compression
fittings are required
for tube ends. Check
tube size. Use 3/8”
x 3/8”, 1/2” x 3/8”,
or 5/8” x 3/8” compression fittings as
required. Slip nut
and ferrule on water
tubing as shown
and fasten fittings in
place. (Figure 8)
9. Cut two lengths of
3/8” soft copper
tubing and bend to
shape as shown.
Bend tubing to form
gentle curves rather
than sharp bends.
(Figure 9)
10. Connect both pieces
of tubing to filter and
water tube as shown
with compression
fittings. Do not over-
tighten nuts.
(Figure 10)
11. Open the cold water
faucet to expel
trapped air. Open
the supply valve to
allow water to enter
the filter. If any leaks
occur, close the supply valve and open
the faucet to relieve
the pressure, then
gently tighten the
fitting that is leaking. Flush at least 2
gallons through filter
before use (approximately 1 minute of
flushing). Water may
run cloudy due to air
but will clear quickly.
