MODEL 740 IN-LINE
INSTRUCTION GUIDE
1. Choose a suitable location after filter and heater. The
feeder may be plumbed with flow in either direction. Install
in a vertical position.
2. Remove cap, basket and spring. Cement PVC pipe into
feeder ports. Follow PVC cement manufacturer’s recom-
mendations. (Be careful not to get cement into basket
chamber.)
3. After installation has been made, fill hot tub or spa with
water, turn on pump and check for leaks.
CAUTION: Use ONLY Bromine sticks or tablets. DO NOT
USE ANY TYPE OF CHLORINE. NEVER mix or use with
any other chemicals.
1. Turn off pump.
2. Fill basket with Bromine sticks or tablets. Do not fill
above top of basket. (See above caution.) DO NOT MIX
CHEMICALS.
3. Replace cap.
4. Turn cap to proper setting for gallonage and filtration
time of your spa. See Guidelines.
5. Start pump.
NOTE: Each spa or hot tub is different in it’s gallonage, fil-
tration time, usage, location (indoors or outdoors) and cli-
mate. These circumstances will affect the actual feed
adjustments necessary.
Determine the Sani-King feed adjustment setting by follow-
ing these guidelines. Using the appropriate Test Kit for
Bromine, maintain a desirable 2.0-4.0 ppm.

After first filling hot tub or spa, the residual may not be
obtained for as long as two days due to the above men-
tioned circumstances.
Turn cap to the appropriate setting from chart above. Start
pump, and run at high speed for approximately 12 hours.
Check residual. If less than 2.0 ppm, continue pump at high
speed for an additional 12 hours at the same setting. If after
24 hours, the residual has not been obtained, turn cap
clockwise one full turn and repeat the procedure. Then fine
tune the setting (clockwise or counterclockwise) for your
environment and spa usage.
Some circumstances during the first few weeks of tub instal-
lation may require initial settings to be greater than normal.
These circumstances often include; unusually heavy bather
usages, leaching of the wood (hot tubs), bacteria, location
(indoors or outdoors) and climate. The setting may need to be
1/2 to 1 full turn greater than the chart shows. Residual of
between 2.0 to 4.0 ppm is desirable during the first few weeks
of start up. Retaining this residual there after, using the chart
provided, may require a reduced setting.
RECOMMENDATIONS
For best results, heat spa or hot tub to desired temperature
(approximately 102°F) and refrain from using spa until a
sanitary residual reading of 2.0-4.0 ppm is obtained.
