C. ADDITIONAL INSTALLATION
D. STARTUP PROCEDURES
E. WHEN YOU CLEAN YOUR FILTER
1. Pressure gauge
a. Hole in cover is already pre-tapped. Apply PTFE (Teflon®) tape to pressure gauge threads and
screw gauge into threads on cover.
2. CMP recommends 1 gallon per minute (gpm) per square foot of filter for proper filtration.
a. 50 sq ft filter = 50 gpm
b. Pair filter with appropriately sized pump for optimal filter performance.
c.
Too much flow rate through cartridge filter may decrease desired performance
of filter system. Exceeding recommended flow rate may damage the filter element and/or water
features in line with filter.
3. Apply O-ring lube to Oring on cover.
4. Tighten down cover until locking tab is secure.
5. Do not over-tighten.
6. Check for leaks in system before operating.
7.
WARNING
Maximum recommended pressure is 50 psi.
1. Monitor pressure difference from when the filter was originally installed.
a. If pressure rises 10 psi or greater, check filter element and clean or replace if necessary.
b. If flow drops below desired rate, check filter element and clean or replace if necessary.
c.
WARNING
Do not allow pressure to exceed 50 psi
2. MY ORIGINAL STARTING PRESSURE IS ____________ PSI. I SHOULD CLEAN MY FILTER AT _________ PSI
3. Flow rate and pressure may not always indicate when filter needs to be cleaned.
4. Check your filter if you notice any other performance variation besides psi change.
1.
WARNING
Make sure both suction and discharge valves are in the open position.
2. Open manual air relief valve (3 turns counter clockwise)
a. Air will vent out of the discharge outlet to the pool and through the manual relief valve.
b. Once all air is out of the system, close manual relief air valve. Pressure gauge should read “0” psi.
3. Record starting pressure of the system. This may help provide an indicator of when the filter needs
to be cleaned.
