ASSEMBLY:
Be sure to use caution when handling the TankJet 78M.
Always work on a flat, stable surface. The TankJet 78M will
stand upright on the tabletop to ease disassembly.
Before reassembling, inspect all parts for wear or damage.
Replace all defective or worn parts. Parts must be clean and
free of dirt or debris to ensure proper operation.

Rotary Housing (12), then place the Dowel Pin (13) into the
Rotary Housing (12) to keep the assembly in place. The
Hub Cap (18) and Dowel Pin (13) may not line up perfectly
on the first attempt, to line them up, simply spin the Hub
Cap (18) in either direction till the Dowel Pin (13) drops into
place.
6. Place another Rotary Housing Bearing (11) onto the top of
the Rotary Housing (12), then place the Housing Gear (10)
on top of that. When lined up correctly, the Housing Gear
(10) should be able to spin the Nozzle Hub (16) and vice

over the Inlet (1), Housing (5) and Housing Gear (10).
SPECIAL CLEANING INSTRUCTIONS:
When using corrosive chemicals for cleaning operations,
special care must be given after a cleaning cycle to
remove them. Cleaning off the chemicals prevents damage
to the TankJet 78M and helps to minimize health hazards or
cross contamination.
1. Allow all chemicals to drain from the TankJet 78M.
2. When possible and appropriate for the process, supply
clean water to the unit and run a complete cleaning cycle
for 3 to 6 minutes.
3. If not possible to flush with clean water in the process
vessel, using appropriate safety equipment for working
with potentially hazardous chemicals, remove unit from
vessel and submerge in an open top 55-gallon (200-litre)
drum filled with clean water for 5 to 10 minutes.
4. Using appropriate safety equipment for working with
potentially hazardous chemicals, remove unit from drum
and follow disassembly instructions above, rinsing each
individual part in clean water.
5. Once individual parts are clean and dried, inspect for
wear or damage and replace as necessary.
6. Reassemble unit using instructions above.
