WARNING
Changing the two (2) or three (3) port diverter valve
handle while there is pressurized air in the system
can cause product failure or also cause the fi lter
lid to be blown off, which can cause death, se ri ous
personal injury or property damage.
Caution
Dust released during normal handling of diatomaceous
earth can cause eye and respiratory irritation. Prolonged
breathing of excess concentrations of dust may cause
lung damage.
Caution
Never operate the fi lter in excess of three (3)
minutes without use of diatomaceous earth (DE). DE
is the substance that fi lters the water, the fi lter cloth
merely supports the DE. Operating without DE will
damage fi lter grids and short en fi ltering cycles.
Caution
DO NOT operate the fi lter at water temperatures
above 105° F (40.6° C). Water temperatures above
the manufacturer's recommendations will shorten the
life span of the fi lter and void the warranty.
5.
After the fi rst week of operation, check the
clamp and retighten if necessary.
6.
Check the fi lter clamp at least once a month.
Section 4. Start-Up and Operation
4.1 Preparing Diatomaceous Earth
Your fi lter requires diatomaceous earth (DE) for
proper fi ltration and operation. The fi lter grids must
be precoated with DE in order to protect their sur-
faces and provide the most effi cient fi ltering action.
Refer to Table 2 for the proper quantity of DE to use
with your fi lter.
1.
Using a one (1) pound coffee can, fi ll the can
with diatomaceous earth (DE). Do not pack or
compress the DE into the can.
2.
Mix the required amount of DE with suffi cient
water in a separate bucket to make a thin, milky
mixture (slurry).
NOTE
Excess DE will clog the system. Use amount
specifi ed in this manual.
3.
Use the following instructions to coat the fi lter
grids.
