INSPECTION ROUTINES
Every 48 hours …
• Visually inspect the FTS System.
• Check for unusual noise or vibration.
• Observe pressure gauges for normal readings.
Every 30 days …
• Check the pre-strainer and clean if necessary.
• Observe a backwash cycle for duration time and the condition of backwash water. It
should be relatively dirty at first and clean just before the backwash cycle ends.
Every 6 months …
• Shut-off the system, relieve filter tank pressure and inspect the media sand for
cleanliness, a relatively flat surface (no coning or funneling) and no indications of
solidification. Adjust backwash flow rate and/or pressure to overcome any unusual
characteristics.
When changing the sand media …
• Shutdown and isolate the system (see shutdown procedures for more details). Drain
all water from the system. Open the sand filter at the center flange of the tank shell
(see INSTALLATION PROCEDURES, #12 for details). Scoop and flush all sand from
the lower shell.
• Inspect the underdrain for secure connections and damage. Replace parts as
necessary.
• Add water to the tank (1/3 to 1/2 full). Add appropriate quantity of sand (see chart on
page 1).
SHUTDOWN PROCEDURES
1. Initiate a backwash cycle to clean the filter of all contaminants.
2. Shut-off and lock-out all electrical supply to the filter system.
3. Close the inlet and outlet service valves to isolate the filter system.
4. Drain all water from the filter system. This is typically accomplished by opening a
valve downstream of the FTS System (must be lower than the FTS System).
5. Clean the pre-strainer to the pump of all debris.
6. Open the filter tank’s access port and inspect the sand media; clean or replace as
necessary.
7. Follow start-up procedures to re-start the FTS System.
