PENTAIR RAINBOW 320 Chlorine, Bromine Feeder

Features:

• No special venting is required.
• Completely enclosed-no escaping gases.
• Positive external no-clog control valve.
• When used with a timer, the feeder is designed to automatically lower the water level so tablets are not soaking during off period of the pump. This allows for more efficientuse of tablets.
• No equipment damage.
• Feeds sanitizer directly to pool or spa.
• All parts are replaceable.
• To prevent over-chlorination during use, completely close the control valve and the built-in check valve will prevent chemicals from being fed into pool or spa.

YOUR LIFEGARD® FEEDER Is THE MOST EFFICIENT AND TROUBLE-FREE AUTOMATIC FEEDER YOU CAN BUY, BUT IT CAN ALSO BE DANGEROUS TO YOU AND YOUR EQUIPMENT. PLEASE FOLLOW INSTRUCTIONS EXACTLY AND HEED ALL CAUTIONS. YOUR SAFETY AND THE PROTECTION OF YOUR EQUIPMENT IS OUR FIRST CONCERN.

It is important to read all information BEFORE proceeding with the installation. The information will guide you in installing your feeder properly and to avoid problems due to improper installation.

IF YOUR POOL OR SPA HAS COPPER PLUMBING…STOP!!
Never install the feeder into copper plumbing as pipe damage will occur. (See Equipment Safety CAUTION Sheet enclosed). NOTE: If heaters are used, a Fireman’s Switch or equivalent must be installed to prevent possible damage and improper operation of Check Valve and other equipment subject to heat damage.

INSTALLATION INSTRUCTIONS MODEL #320
Note: Make sure all pumps and timer switches are in the OFF position.

WHERE TO INSTALL YOUR FEEDER
The #320 feeder is designed for permanent installation in the return line of your new pool or spa and must always be installed after the heater, pool cleaner, valves, etc. If your pool does not have a he

it must be installed after1 or any other piece of equipment.
If your pool is equipped with a solar system it may be necessary to install a Hl FLOW KIT. This kit can be installed if your feeder is not getting adequate flow and/or pressure through the system. Refer to the information on the sheet enclosed. Your feeder may be installed in existing PVC plumbing but will require a union and/or other fittings. The feeder comes complete for installation with 2″ or 1%” PVC plumbing. Choose a site in the return line where the feeder can be installed in a vertical position. Always install as far from any metal equipment as practical since fumes, etc. can corrode them. If the optional corrosion-resistant check valve is required refer to installation instructions before next step.

BASIC PLUMBING INSTALLATION INSTRUCTIONS
2″ OR 1%” PVC PIPE: If feeder is being installed on a p0ol, spa or pool/spa combination, corect plumbing procedures must be followed to insure proper flow through feeder. if pool or spa is plumbed with 2″ PVC pipe, be certain the pump, filter and heater all have 2″ inlet and Outlet fittings. If any part of the equipment has less than 2″ fittings or pipe, then a minimum of 6″ x 12″ reducer bushings must be installed directly into the inlet side of the feeder using the 2″ x 12″ reducer bushings supplied. This will build pressure directly into the feeder insuring proper operation. Continue with 2″ PVC pipe on the outlet side of the feeder.

POOL/SPA COMBINATION: If plumbing and equipment is a full 2″ and the feeder is being installed on the pool return line after the diverter valve, with a portion of the water diverted to the spa, install a minimum section of 6″ x 12″ PVC pipe directly into the inlet side of the feeder using the 2″ X 12″ reducer bushing Supplied. Contnue with 2″ PVG pipe on the outlet side of the feeder. This will compensate for that portion of water being diverted to the spa.
90 ELBOWS : Plumbing a 90° elbow directly into the inlet side of the feeder may cause turbulence inside the elbow. This will prevent water from being scooped into the feeder. A minimum of a 6″ length of PVC pipe should be installed between the 90° elbow and the inlet side of the feeder.

2″ PVC : Simply glue feeder to the return line using PVC SOLVENT CEMENT. Be sure arrows on feeder point in the direction of water flow returning to the pool or spa. 12 PVC: Hemove (22×12 Slip reducer bushings packed inside the feeder and glue into 2″ slip tee on bottom of feeder. Complete installation by gluing into 1%” return line making sure the arrows on feeder point in the direction of water flow returning to the pool or spa. Use only
PVC SOLVENT CEMENT. Follow directions on solvent cement label. Allow to dry. Installation in now complete.

OPERATING INSTRUCTIONS

Before start-up of feeder, your pool should be properly conditioned and the residual should be 1.0 to 1.5 ppm. The water in a newly-filled pool should be properly conditioned to insure maximum effectiveness of the feeder. Consult your local dealer for water conditioning information for your area.

1. Remove the cap of the feeder and fill it with the proper size tablets.
   For Pools: 1″ or 3″ dia. tablets For Spas: 1″ dia. tablets in optional Spa Chamber.

2. Making sure the O-ring is clean, lubricated with Lifeguard Silicone, and is in place replace the cap. Hand tighten only.

3. Turn on the pump and timer switches for a minimum of 6 to 8 hours.

4. Adjust the control valve according to your pool/spa size.

Use a test kit to determine the chemical residual. It is recommended that the chemical residual be checked daily for the first 5 days. Hemember.. hot days, higher water temperature or increased p0ol/spa
activity will cause your pool/spa to use more sanitizer. When possible, increase the feed rate a day or two in advance. Because the chlorine demand in your pool/spa varies and is dependent on may factors (sunlight, bather load, water temperature, etc) your valve setting may have to be changed from time to time to adjust to these conditions. For example, the winter setting may be #2 while the summer setting is #3. Check the chlorine residual daily to find the ideal setting. Note: Higher numbers dispense more chemical. Small gradual changes are imperative for control.

HOW TO RECHARGE FEEDER

1. Turn the control valve to the closed position. SHUT OFF THE PUMP.
2. Wait one minute. This will allow water and fumes to drain from the feeder.
3. Leave the control valve closed and turn on the pump. The check valve will prevent water from entering the feeder.
4. Remove cap and frill with proper size tablets or sticks. (See Operating Instructions #1)
5. Making sure the O-ring is clean, lubricated with Lifeguard silicone and is in place, replace cap. Hand tighten only.
6. Open the control valve to the original setting. Inspect the inlet line below the control valve each time feeder is recharged. Place lines yearly if necessary.

SPECIAL FEATURES AND INSTRUCTIONS

if while using 3″ diameter tablets the #320 feeder 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

320 has been fitted with an optional opening at the top of the feeder (which

is plugged). To accommodate attachment of the valve and tubing assembly for top entry of water into the feeder, 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. while using diameter tablets the #320 feeder does not provide enough chlorine residual, Switch to 1″ tablets.

1. Turn off the pump and timer switches.
2. Remove the tubing by unscrewing the compression nut at each end of the tubing.
3. Remove the plug at top of the feeder directly above the control valve.
4. Remove control valve. lf nipple stays in the valve, carefully remove by using pliers at the center of the nipple. There is no need to remove the 90° tube fittings.
5. Wrapping with 2 or 3 wraps of threaded tape in the opposite direction of tightening. Screw into the opening where the control valve was attached. Hand tightens plus 2 or 3 turns. Do not over tighten.
6. Wrap threads of the nipple with threaded tape.Thread nipple into the top opening. Finger tighten only. Thread the valve onto the nipple. After nipple starts to turn from the tightening valve, 2 to 3 more turns is enough. The nipple or valve can be broken by overtightening.
7. Slide compression nut over a long section of the tube. Slide tube over tapered part of 90° tube fitting and tighten. Hand tightens only. Repeat for another end of the tubing.
8. Set control valve to #1. Turn on the pump and timers. Check residual daily to determine proper setting. Smal gradual changes are imperative for control.

BELOW WATER LEVEL INSTALLATION
Feeder 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 high chlorinated water during recharging. Drill and tap a 4″ MPT hole at the same level the control valve is located. Make sure there is no water or tablets inside the feeder before drilling. Install optional drain valve, Part R172060, or a suitable chemical-resistant drain valve.

BELOW WATER LEVEL RECHARGING INSTRUCTIONS

1. Shut off the pump and timer switches.

2. Shut off the control valve.

3. Place a clean container under drain and open the drain valve.

4. Exercise extreme caution when opening or servicing feeder. Do not inhale fumes.
   Wear protective gear. Remove cap. Water will now drain from feeder. Empty container back into pool or spa.

5. Close drain valve. fill with proper size tablets or sticks.

6. Making sure the O-ring is clean, lubricated with Lifeguard Silicone and in place, replace cap.

7. Turn on the pump and timer switches.

8. Reset the control valve to the original setting. Inspect inlet and out recharged. Replace lines yearly if necessary. line each time feeder

4. Disconnect another end of the Feeder tube from the control valve 90° elbow, by loosening the compression nut. Use the compression nuts from old tube to attach new 6′ section (2).
5. Push compression nut over tubing end, then push tubing onto tapered end of the elbow. Tighten nut firmly by hand.
6. Connect another end of plumbing. IF THE POOL/SPA HAS A HEATER, INSTALL IT BETWEEN THE FILTER AND THE HEATER. IF YOUR POOL/SPA HAS A SOLAR SYSTEM, INSTALL IT BEFORE THE SOLAR SYSTEM INLET LINE. IF NO HEATER, INSTALL IT BETWEEN THE PUMP AND FILTER. Drill /16″ hole in plumbing, remove burrs, and install saddle clamp assembly. (See illustration) Tighten the clamp with a screwdriver. Slide small stainless steel clamp #3 over tubing #2 and slide tubing over saddle tube fitting #4. Secure tubing to fitting by tightening camp with a screwdriver. Make sure the clamp is below rib at end of the saddle tube fitting.
7. To install 2″ CHECK VALVE, cut tube approximately 6″ away from plumbing connection. Remove compression nuts from the check valve. Slide nuts over both ends of the tube. Insert check valve ends into both pieces of tubing and tighten compression nuts firmly by hand. Be sure the arrow “FLOW” is pointing toward the Feeder.

EXTENT IONS

• Going on vacation?
• Do.Need more chlorine?
• Filling Chlorinator/Brominator too frequently?

LIFEGUARD CHLORINATOR EXTENSIONS SOLVE THE ABOVE PROBLEMS B3Y:

1. Increasing tablet capacity.
2. A larger chamber size allows for more erosion of tablets. (See special instructions below)
   The 10″ extension doubles and the 20″ extension triples (approximately) the capacity and time
   between refills. *AVAILABLE THROUGH LIFEGUARD DEALERS ONLY.
   NOTE: On free-standing #300 series chlorinators, the base of the chlorinator should be secured to prevent the possibility of the chlorinator tipping over due to increased height.

INSTALLATION INSTRUCTIONS

1. Follow recharging instructions to the point of filling with tablets
2. Making sure the O-Ring is clean, lubricated with Lifeguard Silicone and in place, screw on the extension tightly and secure it with a lock screw. (You may wish to wait until back in operation before tightening the screw to insure against leaks)
3. Fill with tablets and continue with the normal recharging procedure.

SPECIAL INSTRUCTIONS:

The large chamber size will result in more chlorine being dispensed at the same valve setting, therefore, once installed, several days of monitoring will be necessary to readjust chlorinator output.

#R172288 1%” & 2″ SLIP

SPRING CHECK VALVE

• Special corrosion resistant 1%” & 2″ slip spring check valve can be used to check back flow of fluids, air, etc.
• Full free flow design Special Spring and Seal for corrosive applications.
• Enclosed spring insuring free operation.
• Very effective when used in conjunction with chlorinator to check back flow of chemicals to pool/spa equipment, preventing corrosion problems and damage.

Typical check valve installation

NOTE: If heaters are used, a Fireman’s Switch or another safety device must be installed to prevent possible damage and improper operation of Check Valve and other equipment subject to heat damage.

EQUIPMENT SAFETY

CAUTION!
PLEASE READ CAREFULLY

Since most pool’s 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.

Installation of the OPTIONAL Rainbow #R172288 positive seal, corrosion resistant check valve SHOWN ON REVERSE SIDE will prevent the backflow of corrosive liquids and gases that can damage equipment containing metallic components. Examples listed above.

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 feeders. Check with
manufacturer for compatibility.
