For Proper Performance

1) If using a multi-speed pump, run pump for at
least 6 hours per day at high speed (at least 40
gpm).

If the pump will run on low speed 24 hours per day
or less than 6 hours per day on
high speed, you must bleed the air
while the pump is on by unscrewing
the cap knob until water appears.
Then screw the knob back on.
Repeat this process each time the
cap is removed for any reason.

2) Install system with 4-8 psi back pressure.

Lower back pressures could
result in under chlorination.
Adjust eye ball fittings in the
return jets to a smaller size to
increase back pressure. Contact
King Technology at 800-222-
0169 for a cap tapped for a
pressure gauge to determine
back pressure at pool start-up.

3) Special installation:

• If water flow is higher than 80 gpm, see
diagram A.

• If an in-floor cleaner is included with pool,
see diagram B, with two options. Preferred
installation is Option 1 with two separate lines.

• If set-up is a pool and spa combination with
common equipment, see diagram C.

• Any additional sanitizing equipment that is
installed with FROG® must be installed after
FROG® (never before) on the return line
to the pool.

NOTE: Over chlorination or damage to the POOL
FROG XL PRO® or other equipment could result if
these special installations are not used in these
situations.
