4.1 STARTUP
This section applies to new pools and seasonal start ups.
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 product failure or also cause
the filter lid to be blown off, which can cause death,
serious personal injury or property damage.
NEVER start pump while standing within 5 feet of the
filter. Starting the pump while there is pressurized air
in the system can cause product failure or also cause
the filter lid to be blown off, which can cause death,
serious personal injury or property damage.
1. Make sure pool is cleaned before filling with water to avoid
component damage from excessive debris and dirt particles.
• If the pool is new concrete, gunite or has a lot of debris
or plaster dust which may be difficult to remove; it is
recommended that the filter be run in filtration “FILTER”
mode for 48 hours before performing the backwash
procedure described below.
2. Turn off the pump at the circuit breaker.
3. Check that the drain plug is in place and tight.
4. Check that the lid is correctly seated and tight. See
Figure 5
.
• Ensure the pressure gauge/release valve assembly is fully
installed in the lid.
5. Ensure the backwash piping is open.
6. Set backwash valve to the “Backwash” position.
• If a multiport valve is used, set handle to the “Backwash”
position indicated on the dial.
• If a slide valve is used, push the handle down to the
backwash position and turn the handle to lock it in place.
• For details please review the manufacturers instruction
manual for your backwash valve.
7. Restore power to the pump at the breaker.
8. If the pump does not immediately prime, the following steps
can be taken to achieve prime.
• If necessary open the pump basket lid.
• 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.)
• If the pump is located below the water level of the pool, you
can open the filter pressure release valve to prime the pump
with water.
• If the pump is located above the water level, remove the lid
and fill the basket with water before starting the pump.
• Prior to replacing the pump lid, check for debris around the lid
O-ring seat. Debris around the lid O-ring seat will cause air to
leak into the system, and make it difficult to prime the pump.
• Hand-tighten the lid to make an air tight seal.
• Do not use any tools to tighten the lid.
• Ensure that the lid is secure.
• Ensure that all isolation valves are open.
• Ensure that the unions are tight.
9. Open the air release valve by turning the thumbscrew on the
back of the pressure gauge housing counterclockwise.
• Do not remove the thumbscrew. See
Figure 5
.
10. Stand clear of the filter and turn the filter pump on.
11. Once the filter pump is primed and begins filling the filter. The
vent hole on the pressure gauge will expel air.
• If the vent hole does not expel air, turn off the filter pump.
• Double check that all isolation valves are open.
• Check to ensure that the filter pump has successfully primed
and is filling the filter with water.
• Double check that the release valve thumbscrew has been
loosened
12. Air venting is complete when a steady stream of water is
being produced at the vent hole.
13. You should also see a steady flow of water being discharged
from the “waste” drain line.
14. Close the air release valve by turning the thumbscrew on the
back of the pressure gauge housing clockwise until the flow of
water from the vent hole stops.
15. Run the filter using the backwash setting on your backwash
valve for at least 3 to 5 minutes or until water runs clear.
4.2 oPeRATion
This filter operates with a variety of backwash valves. The
operational procedures described below attempt to cover
use of the most common backwash valves. However, it
is always recommended that you consult the manual for
the backwash valve you are using on the filter.
CAUTION
To prevent the possibility of personal injury and
equipment damage, always turn the pump off before
changing the position of a backwash valve.
WARNING
NEVER operate the filter system at more than 50 psi
of pressure. Operating filter system in excess of 50
psi can cause product failure or also cause the filter
lid to be blown off, which can cause death, serious
personal injury or property damage.
DO NOT operate filter at water temperatures above
104° F (40° C). Water temperatures above the
manufacturer’s recommendations will shorten the life
span of the filter and void the warranty.
