9.1 Disassembly of DON with Pulse meter
Concerning options Hx, Dx, Gx, Bx, Kx and Rx
9.1.1 Pulse output board removal (refer exploded view diagram)
To remove the pulse output board, remove the 4 electronic cover screws (10),
and remove the electronic cover (9). The pulse output board (6) can now be
accessed and removed via the removal of the electronic board screws (7).
9.1.2 Oval gear removal for DON-x05…DON-x15 (refer exploded view
diagram)
For access to the oval wheel, remove the 4 lower meter body screws (5). With
care, remove the upper meter body assembly (4) being careful not to damage or
misplace the O-ring (3) or changing the positioning of the oval wheels (2) and/or
damaging them.
For DON models DON-x05 to DON-x10, when disassembling, please notice the
notches located on the meter bodies (1 & 4) face just outside the o-ring groove.
These markings must be matched during assembly. Only one oval wheel is
equipped with a magnet in these small flow meters. It must be mounted on the
bearing shaft opposite to the notch. For these oval wheels, the sides without
boring hole for the magnet must face upwards, see detail A. For all other devices
(DON-x15 and larger) both gears are equipped with magnets and can be
mounted in any position.
