Outlet Valve (optional)
Purge Valve
Cleaning  sediment  from  your  filter  is 
easy. Simply open the purge valve for 
a few seconds (while system is under 
pressure from pump or tank).
In irrigation systems without pressure 
tanks, best results can be acheived by 
(1)  opening  the  purge  valve,  (2) 
closing  the  outlet  valve  (or  keep 
sprinkler solenoid valves closed), and 
(3)  turning  on  the  pump  for  about 
10-30  seconds.    This  will  direct  all 
available  pressure  to  the  cleaning  of 
the filter element.
*Note: To avoid water-hammer 
always close the valves slowly.*
S U N   S H I E L D ®
Screen turn green?  Or brown?  That's 
algae,  and  it's  caused  by  adding  light 
to your water.  Though it's not harmful 
to  humans,  it looks  bad  and  clogs  the 
filter  screen.    We  can  help  prevent  it 
with our Sun Shield®,  It slips over the 
clear  cover and  cuts out  the  sunlight,   
preventing algae growth. Just slip it off 
when  checking  the  filter  for  cleaning.   
Ask  your  supplier for  the  Sun  Shield® 
if your filter is to be installed outside in 
the  warm sunshine.  (The  small sizes 
also double as nifty little beverage "can 
coolers".)
1. Close Outlet Valve
 *(if necessary)
2. Open Purge Valves 
one at a time, starting with
the one nearest the source
of pressure.
Rusco Spin-Down® filters are great prefilters. Install one or more 
before a cartridge filter to increase the lifespan of the cartridges.
