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.
WARNING
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

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.
