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 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
resequenced to Rinse, and then Filter, 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 level concrete slab,
very firm ground, or equivalent, as recommended by your
pool dealer. Position the filter so that the piping

2.
Assemble the filter control valve to filter. Align the two (2)
valve pipe connections, with O-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.
Do not overtighten.

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 5.)
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.
