Read installation instructions rst before installing. Check parts to ensure that no damage has occurred during transit and that no
parts are missing. Also check the diameter of the pipe and the range marked on the clamp to ensure you have the proper size.

Step 1 • Thoroughly clean pipe surface that
will be covered by the saddle.
Step 4 • Tighten all nuts
evenly in 20 ft-lbs. increments. Use a wrench with at least a 12 inch handle.
Step 2 • Back off
nut to the end of the bolt – DO NOT RE­MOVE. Separate the ends of the saddle and position the tap such that the out­let is in the correct location.
Step 3 • Slide lifter bar
up the receiver lug pro­le and snap into place over the sidebar edge. Make sure the gasket has seated itself at onto the pipe face.

Nom. Pipe Diameter Torque
4" and below 30-40 ft-lbs. 6" and above 75 ft-lbs.
Note:
40 ft-lbs. torque = 12" wrench w/40 lbs. force 75ft-lbs. torque = 12" wrench w/75 lbs. force
For best results, wait 10 minutes and then re-tighten to proper torque.
Pressure test before tapping.
Backll and compact carefully around saddle and service line.

PRECAUTIONS
INSTALLATION INSTRUCTIONS
Style 306-H
1. Check diameter of pipe to make sure you are using the
correctly sized saddle.
2. Clean pipe to remove as much dirt and corrosion as
possible from the surface.
3. Make sure no foreign materials stick to the gasket as it
is brought around the pipe, nor become lodged between gasket and pipe as nuts are tightened.
4. Avoid loose tting wrenches, or wrenches too short to
achieve proper torque.
5. Keep threads free of foreign material to facilitate tight-
ening.
6. Bolts are often not tightened enough when a torque wrench
is not used. Take extra care in this situation to make sure proper tightening occurs.
7. Always pressure test for leaks before backlling.
8. Backll and compact carefully around clamp.
9. When reinstalling parts with stainless steel hardware there
may be a loss in pressure holding ability due to worn or damaged threads during the orignal installation
COMMON INSTALLATION PROBLEMS
1. Bolts are not tightened to the proper torque.
2. Rocks or debris cutting gasket.
3. Dirt on threads of bolts or nuts.
4. Installing in the heat of the day.
PRODUCT LIMITATIONS
High Density Polyethylene Pipe (HDPE) has a lower modules of elasticity and higher coefcient of thermal expansion than other pipe materials. These properties cause HDPE pipe to expand and contract much more from changes in temperature and/or pressure than other piping materials. Because of these and other properties, great care must be taken when installing conventional tting on HDPE.
This product has been provided with the proper number of spring washers for the conditions described in the following limita­tions.
HDPE LIMITATIONS:
• Pipe must be manufactured in accordance with AWWA C906-90, or AWWA C904-06.
• Operating temperatures are limited to 85° F maximum and 32° F minimum.
• Operating pressure is limited to 150 psi or the rating of the pipe, whichever is less.
• Pipe systems must be designed to compensate for pipe movement so as to prevent ttings from migrating or rotating on the pipe.
• Products are intended for use in underground service only.
• Products are not to be used on pressurized HDPE pipe with an SDR greater than 26 or PEX with SDR greater than 9.
ROMAC CANNOT WARRANT PRODUCTS USED IN APPLICATIONS THAT ARE OUTSIDE ONE OR MORE OF THESE LIMITATIONS. CONTACT ROMAC’S ENGINEERING DEPARTMENT AT 1-800-426-9341 IF YOU HAVE QUESTIONS ABOUT THE USE OF OUR PRODUCTS ON HDPE PIPE.
HDPE PRECAUTIONS:
Try always to install ttings when pipe is at its coldest.
Be sure that spring washers are stacked properly (see drawing at right).
This product is designed for a 53° F temperature range maxi­mum.
