10. Provide space and lighting for routine maintenance access. Do
not mount electrical controls over filter. Install electrical
controls (e.g., on/off switches, timers, control systems, etc.) at
least five (5) feet from the filter. This will allow you enough
room to stand clear of the filter during system start up.
11. Allow sufficient clearance around the filter to permit visual
verification that the clamp is properly installed around the tank
flanges, see Figure 1.
12. Allow sufficient space above the filter to remove the filter lid for
cleaning and servicing. This distance will vary with the model of
filter you are using. See Table 1. for the required vertical
clearance.
B. TO OPERATE FILTER
1. Set rotary valve handle in the filter position.
2. Open air relief valve on top of filter. STAND CLEAR OF THE FILTER.
3. Start pump and wait until a steady jet of water emerges from air relief valve, then close valve.
4. Introduce the required amount of Diatomaceous Earth into filter, see page 2.
5. Filter will operate efficiently until pressure gauge indicates time for
backwashing.
C. TO BACKWASH (CLEAN) FILTER
WARNING
To prevent equipment damage and possible bodily injury and/or property damage,
always turn the pump off before changing the valve positions.
1. Pressure backwashing is accomplished in three easy steps:
a. Turn pump off.
b. Rotate handle of rotary valve 90
o
as shown in Figure 2.
STAND CLEAR OF THE FILTER.
c. Turn pump on.
d. Backwash for approximately two minutes or until effluent
appears clean. When backwashing is complete, turn pump
off, rotate handle back to filter position and you are ready
for filter operation again. Precoat filter with D.E. as
shown on page 2.
WARNING
THIS FILTER OPERATES UNDER HIGH PRESSURE. WHEN ANY PART OF THE CIRCULATING SYSTEM, e.g., CLAMP, PUMP,
FILTER, VALVE(S), ETC. IS SERVICED, AIR CAN ENTER THE SYSTEM AND BECOME PRESSURIZED. PRESSURIZED AIR CAN
CAUSE THE LID TO BE BLOWN OFF WHICH CAN RESULT IN SEVERE INJURY, DEATH, OR PROPERTY DAMAGE. TO AVOID
THIS POTENTIAL HAZARD, FOLLOW THESE INSTRUCTIONS.
