WARNING – To avoid dangerous or fatal electrical shock, turn OFF power to motor before working on electrical connections.

WARNING – Failure to bond pump to pool structure will increase risk for electrocution and could result in injury or death. To reduce the

risk of electric shock, see installation instructions and consult a professional electrician on how to bond pump. Also, contact a licensed electrician for
information on local electrical codes for bonding requirements.

Your Hayward Pro Series high-rate sand filter is a high
performance, totally corrosion-proof filter that blends superior
flow characteristics and features with ease of operation. It
represents the very latest in high-rate sand filter technology. It
is virtually foolproof in design and operation and when
installed, operated and maintained according to instructions,
your filter will produce clear, sparkling water with only mini mal
attention and care.

HOW IT WORKS

Your filter uses special filter sand to remove dirt particles from
pool water. Filter sand is loaded into the filter tank and
functions as the permanent dirt removing media. The pool
water, which contains suspended dirt particles, is pumped
through your piping system and is automatically directed by the
patented filter control valve to the top of the filter tank. As the
pool water is pumped through the filter sand, dirt particles are
trapped by the sand bed, and filtered out. The cleaned pool
water is returned from the bottom of the filter tank, through the
control valve and back to the pool through the piping system.
This entire sequence is continuous and automatic and provides
total recirculation of pool water through your filter and piping
system.

After a period of time, the accumulated dirt in the filter causes
a resistance to flow, and the flow diminishes. This means it is
time to clean (backwash) your filter. With the control valve in
the backwash position, the water flow is automatically reversed
through the filter so that it is directed to the bottom of the tank,
up through the sand, flushing the previously trapped dirt and
debris out the waste line. Once the filter is backwashed
(cleaned) of dirt, the control valve is manually resequenced to
Rinse, and then Filter, to resume normal filtering.

INSTALLATION

Only simple tools (screwdriver and wrenches), plus pipe
sealant for plastic adapters, are required to install and/or
service the filter.

1. The filter system should be installed, not more than 6 feet

above pool water level, on a level concrete slab, very firm
ground, or equivalent, as recommended by your pool
dealer. Position the filter so that the piping connections,
control valve and winter drain are convenient and
accessible for operation, service and winterizing.

2. Assemble pump and pump mounting base, No.

S160TPAK3 (if supplied) to the filter according to
instructions packed with the base.

3. Loading sand media. Filter sand media is loaded through

the top opening of the filter.

a. Loosen flange clamp and remove Filter Control Valve (if

previously installed).

b. Cap internal pipe with sand shield to prevent sand from

entering it. Be sure pipe is securely in place in bottom
underdrain hub.

c. We recommend filling tank appro ximately 1/2 way with

water to provide a cushioning effect when the filter sand
is poured in. This helps protect the underdrain laterals
from excessive shock. (Be sure the winter drain cap is

securely in place on drain pipe).

NOTE: Check to confirm all laterals are in the down
position before loading with sand. (See Figure A.)

d. Carefully pour in correct amount and grade of filter

sand, as specified on Table 1. (Be sure center pipe
remains centered in opening). Sand surface should be
leveled and should come to within 6" of the top of the
filter tank. Remove sand shield from internal pipe.

4. Assemble Filter Control Valve to filter tank.
a. Loosely pre-as semble both halves of the clamp with one

screw and one nut, turning the nut 2 or 3 t urns. Do not
tighten. Wipe filter flange clean.

b. Insert Filter Control Valve (with valve/flange 0-ring in

place) into the tank neck, taking care that the center pipe
slips into the hole in the bottom of the valve. Install clamp
around

tank and valve flange and assemble second screw
and nut. Tighten just enough so that the valve may be
rotated on tank for final positioning.

c. Wrap two turns of Teflon pipe sealant tape manufactured

for plastic pipe on the ¼” NPT male end of gauge.
Carefully screw pressure gauge, into 1/4"NPT tapped
hole in valve body. Do not o ve r tighten.

d. Connect pump to control valve opening marked PUMP

according to instructions. After connections are made,
tighten valve flange clamp with screwdriver, tapping
around clamp with screwdriver handle to help seat valve
flange clamp.

5. Make return to pool pipe connection to control valve
opening marked RETURN and complete other necessary
plumbing connections, suction lines to pump, waste, etc.

6. Make electrical connections to pump per pump instructions.

7. To prevent water leakage, be sure winter drain cap is

securely in place and all pipe connections are tight.
