 Caution

1. Do not install any of the products in this bulletin at pressures
or temperatures higher than the published ratings.

2. Series 500, HT500, 600 and HT600 must be installed against
standard 1/16” raised faced or flat faced flanges. Do not install
them against recessed flanges such as Victaulic without calling
the factory for proper steel filler flanges. If our rubber flanges
do not have full bearing the expansion joint will be damaged
and leak or fail.

3. Pipe system flanges must be smooth and flat. Screw in brass
inserts such as those used in check valves can damage the rubber
faces if they project above the cast flange face.

4. Water type check valves must exactly center on the rubber
flanges. Valve O.D. and I.D. must conform to raised face
dimensions.

5. Use control rods as listed on INSTALLATION page.

6. Check Chemical Resistance Guide CRG-MR1 for service
elastomer compatibility.

7. Follow INSTALLATION instructions.
