6. Using the two fibre washers (provided with the flow meter),
fit the flowmeter between the joint faces of the upper and
lower tails and tighten the union nuts. Refer to Figure 7-12.
Ensure that the flow meter is installed such that the arrows on
the body of the unit are pointing UPWARDS.
NOTE
!

7.
Carefully route the cable from the flow meter through one
of the grommets in the side of the lower part of the control
panel and up to the integrator unit, installed immediately
above the control panel fascia.
8.
The connection terminals are located towards the bottom
of the rear section of the integrator unit. Pierce the cable
grommet located in the lower face of the integrator unit
(below terminals 9, 10 and 11) and pass the flow meter
cable through.
9.
The flow meter must be connected to terminals 10, 11 and
9 on the terminal block inside the Integrator unit, as follows:
•
White wire – terminal 10
•
Green wire – terminal 11
•
Brown wire – terminal 9
Ensure that the metal ferrule (at the end of the flow meter
cable) is securely trapped under the metal cable clamp to
ground the flow meter cable. Refer to Figure 7-13 (integrator
connection diagram).
NOTE
!
In order to comply with the Measuring Instruments Directive
(MID) 2004/22/EU the flow meter cable MUST NOT be
shortened. Any excess cable should be gathered up (coiled
up) in a suitable location, i.e. where it will not restrict access
to any component (valve, pump, etc.) within the boiler casing.
They should run independently of power cables to limit
interference.
