9.1 Disassembly of DON with Pulse meter
Concerning options Hx, Dx, Gx, Bx, Kx and Bx
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-x04…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-x04, -x10, when disassembling, please notice the dimples
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. The oval gear without magnet must be
mounted on axis that is closest to the dimple. 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.
