FlowCon By-Pass Assembly 1B95200 - 09/2021 PICV Insert and Actuator Installation After proper flushing, set bypass handles to By- pass Operation and drain. Remove the flushing cap on the PICV valve housing and fit the PICV insert with required max. flow setting (please see specific installation instruction for selected insert regarding setting) and fit the selected actuator on the insert. Bypass Operation During Bypass Operation the coil is isolated from the main system. The coil can be serviced after draining, while the main system is still running. Electrically connect the actuator. Please see specific installation instruction for selected ac- tuator. Normal Operation During Normal Operation the coil is an integrated part of the main system. To go from any other op- eration mode and into Normal Operation, slowly open inlet bypass handle 90° to pressurize the coil and then slowly open the outlet bypass handle 90° to put the system in Normal Operation. In Normal Operation the bypass is closed and water will flow through the strainer, into the coil and return through the PICV valve. During this operation, the PICV will balance the flow from closed valve to design flow depending on actual requirements and corresponding to actuator po- sition. Service Exchange of actuator is easily done. Remove ac- tuator and replace without affecting the system or PICV setting. To exchanging of PICV insert, isolated the by- pass by turning the handles to Bypass Opera- tion position, remove the insert and replace with a new pre-set insert. Slowly open inlet bypass handle to re-pressurize the coil and then slowly open the outlet bypass handle to put the system in Normal Operation.
