CHECK VALVE
INSTALLATION INSTRUCTIONS
FOR #300-29X CHLORINATOR: USE #R172324 ½" CHECK VALVE
INSTEAD OF #R172323 ¼" CHECK VALVE AS SHOWN
NOTE:
MAKE SURE ALL PUMPS AND TIMER SWITCHES ARE IN THE OFF POSITION.
#R172323* ¼" CHECK VALVE &
#R172324* ½" CHECK VALVE INSTALLATION:
1. Cut Chlorinator inlet line at desired location.
2. Slide compression nut over one end of line.Make sure arrow on check valve is pointing
toward Chlorinator, insert barbed end of check valve into line and tighten the nut finger
tight. Repeat procedure for other end of check valve.
#R172288 1½"-2" CHECK VALVE INSTALLATION:
1. Cut piping at required location for your situation (refer to drawings).
2. Making sure arrow on check valve is pointing away from equipment and in the
direction of water flow to the pool/spa, glue in check valve using PVC solvent cement.
1½" pipe will glue directly in valve, 2" pipe requires two 2" slip x slip couplings
WITH HEATER
Suction from pool/spa
**Note: For greater flow rate, inlet line
may be installed between filter and pump.
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.

EQUIPMENT SAFETY
CAUTION
PLEASE READ CAREFULLY
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.
Installation of the OPTIONAL Rainbow #R172288, #R172323* and #R172324*
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.
*Note:Valve size and tubing size must match.
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.
