instructions. When used, the safety alert symbol means ATTENTION! BECOME ALERT!
YOUR SAFETY IS INVOLVED! FAILURE TO FOLLOW THESE INSTRUCTIONS MAY

DESCRIPTION
The Check-Trol™ Flange is a combination of an isolation valve, a spring check valve and
a companion flange for circulators. The Check-Trol™ flange allows easy service or
replacement of the circulator without the need to drain the system. The spring check
valve prevents system fluid from flowing in the wrong direction or unwanted direction.
The spring check valve also prevents gravity flow.
INSTALLATION INSTRUCTIONS
1. Install the Check-Trol™ Flange on the discharge side of the pump with arrow pointing
in the direction of flow (the Check-Trol™ Flange has “Check-Trol™” written on handle).
Install the Isolation Flange (without Check Valve) on the suction side of the pump.
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.
