SPECIAL FEATURES AND INSTRUCTIONS
If while using 3" diameter tablets the CH100 chlorinator does not provide enough chlorine residual, switch to 1" tablets. The smaller tablet will erode
faster producing more chlorine residual. If this does not correct the situation, the CH100 has been fitted with an optional opening at the top of the
chlorinator (which is plugged). To accommodate attachment of the valve and tubing assembly for top entry of water into the chlorinator, an additional
length of tubing has been included. The following procedure should only be used if the suggested change has not solved the situation. Top entry in
normal situations can cause over chlorination.
1. Turn off pump and timer switches.
2. Remove tubing by unscrewing compression nut at each end of tubing.
3. Remove plug at top of chlorinator directly above control valve.
4. Remove control valve. If nipple stays in valve, carefully remove by using pliers at the center of nipple. There is no need to remove the 90° tube fittings.
5. Wrap plug with two or three wraps of threaded tape in the opposite direction of tightening. Screw into opening where control valve was attached. Hand-
tighten plus two or three turns. Do not over-tighten.
6. Wrap threads of nipple with threaded tape. Thread nipple into top opening. Finger-tighten only. Thread valve onto nipple. After nipple starts to turn from
tightening valve, two to three more turns is enough. The nipple or valve can be broken by over-tightening.
7. Slide compression nut over long section of tube. Slide tube over tapered part of 90° tube fitting and tighten. Hand-tighten only. Repeat for other end of
tubing.
8. Set control valve to #1. Turn on pump and timers. Check residual daily to determine proper setting. Small gradual changes are imperative for control.
BELOW WATER LEvEL REChARgINg INSTRUCTIONS
1. Shut off pump and timer switches.
2. Shut off control valve.
3. Place a clean container under drain and open drain valve.
4. Exercise extreme caution when opening or servicing chlorinator. Do not inhale fumes. Wear protective gear. Remove cap. Water will now drain from
chlorinator. Empty container back into pool or spa.
5. Close drain valve. Fill with proper size tablets or sticks.
6. Making sure O-ring is clean, lubricated with silicone and is in place, replace cap.
7. Turn on pump and timer switches.
8. Reset control valve to original setting. Inspect inlet and outlet line each time chlorinator is recharged. Replace lines yearly if necessary.
BELOW WATER LEvEL INSTALLATION
Chlorinator should be installed above water level whenever practical. If installed below water level, a drain valve must be installed to prevent spillage
and dangerous splash back of highly chlorinated water during recharging. Drill and tap a 1/4" MPT hole at the same level the control valve is located.
Make sure there is no water or tablets inside the chlorinator before drilling. Install optional drain valve or suitable chemical resistant drain valve.
EQUIPMENT SAFETY
PLEASE READ CAREFULLY
Warning! Since most pool plumbing is not airtight, and a mixture of air and chlorine is highly corrosive to metals, it is important to protect these items
from corrosion in the oFF period when no circulation is taking place. (There is no chance for chlorine corrosion when the circulating system is in operation.)
Of course, corrosion or erosion of metal components can still occur independently of any chlorinator installation for the following reasons:
1. Water velocity too high.
2. Water pH less than 7.2.
3. Total alkalinity less than 100 PPM.
If your pool or spa has any of the following equipment, special plumbing procedures must be followed for safe operation:
1. Brass or bronze gate, rotary or backwash valves.
2. The preceding valves constructed of PVC or other plastic material with metallic shafts.
3. Filters, heaters, heat exchanges or other items with metallic tanks, shafts, coils or tubes.
4. Not for use in copper plumbing.
Warning! if your pool is equipped with a permanent built in pool-cleaning system, damage could occur to that system if materials are not compatible
with low pH tri-Chloro chlorinators. Check with manufacturer for compatibility.
