ISC850-99
MODELS C850, C1250
The ASL models C850
and C1250 are high
performance swimming
pool filters with a
maximum flow rating
of 70 gallons per hour.
Manufactured from
Hayward’s exclusive
PermaglassXL
™
material,
ASL is designed to
provide years of
trouble-free operation.
C. PLUMBING
Use 1-1/4” or 1-1/2” I.D. flexible plastic pipe or hose joined
with insert fittings and stainless steel clamps. If rigid PVC is
used, be sure to provide unions for easy servicing.
All plumbing connections on the ASL filter are 1-1/2” N.P.T.
When making connections, use plastic male-end adapters.
Apply three turns of Teflon tape or plastic pipe sealant to the
male threads. Screw the fitting into the thread hand tight;
then using a wrench, tighten one more full turn if necessary.
Adapters have varying tolerances and over tightening with a
wrench may only cause damage to the filter.
Ball type valves are recommended where needed. (See fig. 1)
Connect the pool suction plumbing between the skimmer,
pool outlet, and the pump.
Connect the pool return (inlet) plumbing.
A filter drain valve or plug is furnished with each filter and is
all that is needed for complete filter draining. A manual air
vent valve is furnished to aid in the bleeding of unwanted air
when starting or draining the filter.
All electrical connections should be made in accordance with
local codes.
Refer to pump instruction book for pump information..
NOTE: ANSI/NSPI-4 Article V, standard for above-ground and on-ground
pools, advises that components such as the filtration system, pumps and
heater be positioned so as to prevent their being used as a means of
access to the pool by young children.
