YOUR SAFETY IS INVOLVED! FAILURE TO FOLLOW THESE INSTRUCTIONS MAY

DESCRIPTION
The Isolation Flange (IF) is a combination of an isolation valve and a companion flange
for circulators. The isolation flange allows easy service or replacement of the circulator
without the need to drain the system.
INSTALLATION INSTRUCTIONS
1. Install one IF on the suction side of the hydronic circulator and one on the discharge side.
2. See the following installation instructions and drawings for additional information.
3. Apply torque in even increments to both flange bolts. Refer to the pump manufac-
turers instruction manual for torque value. Both the suction and discharge flanges
must be torqued in this manner.
WARNING: System fluids under temperature or pressure can be hazardous.
Be sure the pressure is relieved and system temperature is below 100°F
(38°C). Failure to follow these instructions could result in property damage and/or
personal injury.
WARNING: To prevent leakage, make certain that the flange bolts have been
adequately torqued. Failure to follow these instructions could result in
personal injury and/or property damage.
CAUTION: Over-tightening and breakage can occur with the use of teflon
pipe joint compounds. Teflon provides lubricity so that care must be
exercised not to over-tighten joints. Failure to follow these instructions could result in
property damage and/or personal injury.
For NPT connections:
a) Apply pipe compound conservatively to the male connecting fittings only.
b) Upon completion of IF installation to piping, check connections for leaks.
