Troubleshooting

1. Make sure your filtration 
system is working properly 
(i.e. clean filter, skimmer and 
pump basket).
2. Make sure circulation time 
is adequate – increase pump 

time if not.
3. Make sure the pool is 
properly balanced 

(see page 3).

4. Shock the water to 
eliminate build up of any 
organic matter.

5. Make sure pool has a 
free chlorine reading of 
1.0 to 3.0 ppm.
6. Check with your dealer 
for more information.

1. Metals in the fill water may 
have been oxidized. Have the 
pool tested. Shock the pool 
and clean the filter until water 
clarity returns.

2. Algae may be trying to 
form – shock the pool, 
increase circulation time if 
needed and clean the filter.

3. Check with your dealer for 
more information.

1. Use an algaecide per the 
directions on the bottle and 
brush the sides of the pool 
often.

2. Clean the filter and shock 
the pool with chlorine daily 
until water clarity returns.

3. Check with your dealer for 
more information.

1. Make sure there are chlorine 
tablets in the Perform-Max. 
Consider using 1” tablets over 
3” pucks for greater output.
2. If reading dropped below 
1.0 ppm, shock pool. Turn 
control dial to minimum when 
shocking and NEVER ADD 
SHOCK IN OR NEAR THE 
SKIMMER. Reset dial 1/2 
setting higher than before 

and continue monitoring daily 
until desired chemical level is 
acheived.
3. Make sure pump run time 
is at least 6 hours on high 
speed (40 gpm or higher) or 
if not, bleed the air from the 
cap knob (see page 17 for 
directions).
4. Try bleeding the air, soaking 
tablets for greater output.

5. Contact your dealer to have 
your back pressure tested to 
ensure it is at least 4 psi.
6. Check for a suction side 
leak by looking for air bubbles 
in your pump basket or at the 
return jet. Contact dealer for 
help in correcting this situation. 
7. Contact King Technology’s 
Customer Service Department 
at 800-222-0169.

1. Turn dial to minimum or
0. When reading drops to 
desired ppm, reset dial 
1 setting lower than the 
starting dial setting and 
continue monitoring daily.  
2. Consider switching 1 inch 
tablets to 3 inch pucks for 
less output.
3. If over-chlorinating at the 
lowest possible setting, 

consider decreasing the 
circulation time. Depending 
on your pump size, you may 
be circulating the water 
more than is necessary.
4. Contact your dealer to 
have your back pressure 
tested. If over 8 psi consider 
a larger eye-ball fitting in the 
return jet.

 5. Check to see if the 
pressure relief valve is 
loose or missing and 
replace. It is a clear plastic 
piece approximately 1” long 
installed inside near the base. 
If loose or missing, it can 
provide another avenue for 
water to reach the chlorine.
6. Contact King Technology’s 
Customer Service Department 
at 800-222-0169.
