4.3 New Pool and Seasonal Start-Up
1.
Set the filter valve (MPV or backwash) to the
"FILTER" position.
2.
Open the pump hair/lint pot lid and fill the pump
basket with water to prime the system. Replace the lid.
(You may have to do this several times on new and
seasonal start-ups.)
3.
Completely open the air release valve on the gauge/air
release assembly by turning the knob on the back of
the assembly fully counterclockwise (do not remove
the knob).
4.
Be sure to open any filter isolation valves that were
installed in the system and that the filter drain plug is
in place.
5.
Stand clear of the filter and start the pump to circulate
water through the system. When a steady stream of
water starts to come out of the air release valve, close
the valve.
6.
If this is a new filter, or the filter has just been
backwashed, add the DE slurry as described in
section 4.2.
7.
Watch the pressure gauge to be sure that the pressure
does not exceed 50 psi in the filter for normal
operation. If the pressure approaches these limits, turn
off the pump and backwash the filter (see Section 6.2).
If the pressure remains high after backwashing and
reapplying the DE slurry, refer to the troubleshooting
guide on page 13 to identify possible causes and
solutions.
9.
After the pressure gauge has stabilized, turn the bezel
ring so that the arrow next to the word "CLEAN"
aligns with the needle of the gauge. As the filter cleans
the water, the grids will clog over time, and the
pressure will increase. When the needle of the
pressure gauge aligns with the arrow next to the
word "DIRTY" on the bezel ring, it is time to backwash
the filter (see Section 6.2).
4.4 Valve Operation
1.
The flow of water through a DE filter is controlled by
an optional backwash valve or multiport valve (MPV).
2.
The handle on top of the backwash valve or MPV can
be moved to different positions. The function of each
position is described below (see Fig. 7).
Note: Depending on the model of backwash valve or
MPV installed with your filter, it may have all or only
some of the positions described below
.
Position
Function
FILTER
Normal filtration and vacuuming.
BACKWASH
Cleaning filter by reversing the
flow.
RINSE
Used after backwash to flush dirt
from the valve.
WASTE
Bypasses filter; used for
vacuuming to waste or lowering
water level.
RECIRCULATE
Bypasses filter for circulating
water to the pool.
CLOSED
Shuts off all flow to the filter and
pool.

SECTION 5.
Filter Disassembly/Assembly
!
Warning
NEVER attempt to assemble, disassemble or
adjust the filter when there is pressurized air in
the system. Starting the pump while there is any
pressurized air in the system can cause the filter
lid to be blown off, which can cause death,
serious personal injury or property damage.
5.1 Filter Tank Disassembly/Assembly
1.
Backwash filter according to the instructions
in section 6.2 (omit this step when first starting a
new filter).
2.
Turn off the pump. Switch off the circuit breaker to the
pump motor.
3.
IMPORTANT: Completely open air release valve on
top of the filter tank to release all air pressure from
inside the tank and system.
4.
Close the filter isolation valves on the system to
prevent flooding. Remove the drain plug located at the
bottom of the filter tank and allow the tank to drain.
