FlowCon PIM™-DP 65-150 mm (2 1/2”-6”) 1H95040 - 04/2020 Installation and Operation Instruction The FlowCon PIM™-DP are available in three different models covering six different sizes: • FlowCon PIM™-DP DN65-80 (2 1/2”-3”) • FlowCon PIM™-DP DN100 (4”) • FlowCon PIM™-DP DN125-150 (5”-6”) Setting After installation and air venting, the desired ΔpCircuit is set by adjusting the setting (figure 2) under the cap on top of the valve. Use a 13 mm (1/2”) Allen key and NOTE: ADJUSTMENT SHOULD BE DONE SLOWLY, APPROXIMATELY ONE TURN EVERY 10 SEC. Increasing the ΔpCircuit by turning clockwise and decrease by turning counter-clockwise. To increase to maximum ΔpCircuit (170 kPaD / 25 psid) turn the setting approximately 15 full turns. FlowCon PIM™-DP DN65-80 (2 1/2”-3”) Figure 1 Installation Prior to installing the FlowCon PIM™-DP (supplied from factory in fully open position), the system should be properly flushed. Capillary tube Do not damage the capillary tube by compressing or bending the tube with a bending radius below 20 mm (3/4”). Capillary tube is to be finger mounted and tightened with 1-3Nm - DO NOT OVER TIGHTEN. Air venting It is important to release all air inside the valve. Upon doing so open and close the partner valve fully. It will make the diaphragm to fully extend and contract and thereby remove all trapped air inside. PUMP MUST BE OPERATIONAL FOR THIS PROCEDURE TO BE EFFECTIVE AND IT MUST BE CARRIED OUT AFTER THE SYSTEM HAS BEEN VENTED.
