MAINTENANCE
Disconnect power to dispenser before removing cover. Drain
liquid from system before loosening any fittings to prevent
excessive spillage.
Dispenser Cabinet
(see assembly drawing)
Disassembly
1. Remove front plate (item 1) by removing two screws (item
16).
2. Remove faceplate (item 51) by removing two screws (item
53).
3. Pull off reset knob (item 50).
4. Remove six screws (item 10) from cabinet top (item 11).
5. Turn switch handle (item 18) to vertical position.
6. Remove top and set aside to expose junction box and meter.
Assembly
1. Replace cabinet top, making sure it slips over the meter and
the outside edges of the cabinet base (item 2).
2. Replace screws in cabinet top. Install the two screws in back
of cabinet before replacing side screws. Position top
squarely before tightening screws.
3. Attach reset knob.
4. Replace faceplate and front plate. Align each before tight-
ening.
Meter
(see 900 meter drawing)
Meter can be completely disassembled without disturbing
piping, or meter can be partially disassembled as required.
Meter Counter Assembly
(item 10)
1. To expose counter assembly, remove front plate and face-
plate per cabinet disassembly.
2. Reassemble by reversing procedure.
NOTE:
Due to complicated assembly methods, individual
counter assembly parts are not available. The complete
assembly must be replaced if problems occur.
Meter Chamber Assembly
(item 3)
1. To expose meter chamber assembly, gear train and seal,
remove four bolts (item 34) from back of meter.
2. Meter chamber assembly can be removed by removing four
screws (item 5).
3. Reassemble by reversing procedure.
Meter chamber assembly consists of upper and lower
chambers and nutating disc. If replacement of any
components of the meter chamber assembly is required, the
complete assembly must be replaced due to the precise
method of its construction. This assures a proper fit and a
correctly operating chamber.
Meter Gear Train and Seal
1. To access gear train or seal, remove two screws (item 5) and
gear frame (item 6).
2. Remove cluster gear (item 20), shaft (item 19) and washer
(item 21).
3. Remove drive gear (item 26) and washers (item 25) by
rotating and pulling drive gear.
4. Remove O-ring seal (item 27). When reassembling seal,
lubricate O-ring with oil or petroleum jelly and replace in
cover.
5. To reassemble, place washer on drive gear shaft. Rotate and
push shaft through O-ring and cover carefully to prevent
damage to O-ring. Shaft must then be guided into pinion
bevel (item 29) if counter has not been removed.
6. Replace remaining parts by reversing procedure.
Meter should operate maintenance free. However, certain
liquids can dry out while in meter housing, causing meter to
stop. If this happens, meter should be thoroughly cleaned (see
cleaning instructions below).
Cleaning Instructions:
1. Meter can be removed from dispenser by removing eight
screws (items 22 and 27 on dispenser drawing).
2. Run a flushing fluid through meter. For a more thorough
cleaning, disassemble meter according to the
ASSEMBLY/DISASSEMBLY section, Meter Chamber
Assembly subsection of this manual. Rinse all meter
components. Recalibrate meter following calibration
instructions.
