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 recom­mendations. (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, fil­tration time, usage, location (indoors or outdoors) and cli­mate. These circumstances will affect the actual feed
adjustments necessary.

Determine the Sani-King feed adjustment setting by follow­ing 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 men­tioned 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 instal­lation 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.

CAUTION: READ CAREFULLY

The Sani-King feeder is designed to use ONLY Bromine
tablets and sticks. DO NOT USE ANY TYPE OF CHLO-

servicing the feeder. ALWAYS follow chemical manufactur­er’s cautions and recommendations carefully for the ulti­mate in water sanitation and conditioning.

1. The basket should be removed annually and rinsed well
in warm water to remove
any chemical buildup that
could cause the basket to
stick. To remove, place a
screwdriver down inside
the basket in the cam slot
at bottom. Turn clockwise

90° so the slot is now perpendicular to the unit ports (or
direction of water flow.) This releases latches under ports so
basket can be pulled out. Simply reverse this process to
replace basket.

inability to seal properly. If in good condition, lubricate with
a silicon-based lubricant only. If o-ring needs to be replaced
contact your dealer or King Technology, Inc.

cap should acquire a leak. The teflon glide seal should then
be replaced. DO NOT LUBRICATE TEFLON GLIDE SEAL.

4. Winterizing unit is necessary if hot tub or spa is located in

freezing climates and not in use during winter. Remove all
chemicals then drain spa, all pipes and the Sani-King
Feeder thoroughly.
