Your Hayward ProSeries™ 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 the least attention and care.
HOW IT WORKS
Your filter uses special filter sand to remove dirt particles from the 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 for 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
sequenced to the Filter position, to resume normal filtering.
INSTALLATION
Only simple tools (screwdriver and wrenches), plus Teflon tape manufactured 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
firm ground, or equivalent, as recommended by your pool dealer.
connections, control valve, and winter drain are convenient and accessible for operation, service and winterizing.
2. Assemble the filter control valve to filter. Align the two (2) valve pipe connections, with 0-rings in place, with the
two openings in the side of the filter tank and press in firmly. Secure the assembly to the tank connections with
the two bulkhead locknuts.
3. Assemble pump and pump mounting base (if supplied) to the filter according to instructions packed with the base.
4. Loading sand media. Filter sand media is loaded through the top opening of the filter.
a. Remove the top diffuser from the internal diffuser elbow pipe and place flexible, automatic air relief tube to the side,
out of the way, inside the tank.
b. Cap the internal diffuser elbow pipe with the sand shield provided to prevent sand from entering it.
c. It is good practice to fill tank approximately 1/2 way with water to provide a cushioning effect when the filter sand is
poured in. This helps protect the under-drain laterals from excessive shock. (Be sure the 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 on Page 6.)
d. Carefully pour in correct amount and grade of filter sand, as specified. Sand surface should be leveled and should
come to about 6" from the top of the filter tank. Use no more than the recommended amount of sand.
e. Remove the sand shield from internal diffuser elbow pipe.
f. Replace diffuser on internal diffuser elbow pipe, positioning
automatic air relief tube through the hole provided in the
diffuser.
g. Wipe filter flange clean.
h. Insert top closure dome (with flange 0-ring in place) into the tank
neck. Place clamp around dome flange and tank flange and
tighten with screwdriver, tapping around clamp with screwdriver
handle to help seat flange clamp.
5. Connect pump to control valve opening marked PORT B (middle
port). Make return to pool pipe connection to control valve opening
marked PORT E (bottom) 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 drain cap is securely in place and
all pipe connections are tight.
Do not overtighten.
