Measurement
Measure the ΔpCircuit on the p/t plugs

(figure 2)
while turning the adjustment . WAIT UNTIL
THE VALVE STABILIZES ITSELF.
Close off procedure
1. Turn the adjustment bolt under the cap 
(figure 2) clockwise to fully open position (max.
12.5 Nm).
2. Turn off the ball valve  (figure 2) by position-
ing the handle across the pipe and wait for at
least 1 minute.
3. Close the on/off bolt  (figure 2) all the way
by turning clockwise with a flat screwdriver on
DN65/80 (2 1/2”) or a 13 mm (1/2”) Allen key
on DN80/100 (3”/4”) and DN125/150 (5”/6”).
To open the valve, please follow steps 1 through
3 in reverse order.
Filter cleaning
1. Isolate the filter by turning the valve off (fol-
low the close off procedure).
2. Then remove the copper tubing by loosening
the connection nuts . Experiencing some
water leaking is possible due to downstream
pressure.
3. Remove the filter housing  and thereafter
remove the filter  with a sharp pick. BE
CAREFUL NOT TO DAMAGE ENLARGEN
THE FILTER.
4. Clean the filter and put it back in. It is recom-
mended also to inspect the flow restrictor for
blockage .

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”)
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.
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, APPROXIMA-
TELY 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.
