Spraying Systems Co. components should be used, in
order to maintain proper machine operation and safety.
DISASSEMBLY:
Be sure to use caution when handling the TankJet
®
78.
Always work on a flat, stable surface. The TankJet 78 will
stand upright on the tabletop to ease disassembly.
1. Remove the top retaining clip (23) and housing cap (item 1).
2. Remove wrap-around clip (4) and stator (5).
3. Remove the lower retainer clip (23) and housing (6).
4. Remove rotor retainer clip (22). The rotor (7), rotor
bearing (8), housing gear (9), and top gear bearing
(10) can now be removed.
5. Lift the rotary housing (12) off the shaft (14) and main
bearing (13) and set aside.
6. Remove the o-rings (3) from the housing cap (1) and
housing gear (9).
7. Remove the hub retainer clip. Use a flathead screwdriver
to pry it free if necessary.
8. Remove the hub cap (21), hub assembly (15-20), and hub
gear bearing (10).
9. To disassemble the hub assembly, remove retaining clip
(23) and separate the hub (16) from the hub gear (15).
10. Remove the wrap-around clips (19) from the nozzles (18)
and remove the stabilizing vanes (17). For TankJet 78D
units, repeat steps 7-10 for the second hub.
ASSEMBLY:
Be sure to use caution when handling the TankJet 78.
Always work on a flat, stable surface. The TankJet 78 will
stand upright on the tabletop to ease assembly.
Before assembling, 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.
1. Place stabilizing vanes (17) inside nozzles (18) and
assemble to hub (16), securing with wrap-around clips
(19). Note these clips are larger than wrap-around
clip (4).
2. Insert the hub gear (15) into the hub (16) and secure with a
retaining clip (23).
3. Insert a gear bearing (10) into the hub gear (15), and place
hub assembly onto rotary housing (12).
4. Slide the hub cap bearing (20) onto the hub cap (21).
Note the direction of the bearing is critical and will not
assemble incorrectly.
5. Insert the hub cap (21) into the rotary housing (12) and
secure with the hub retaining clip (11). For TankJet 78D
units, repeat steps 1-5 for the second hub.
6. Place the other gear bearing (10) onto the rotary housing
(12). It should seat properly on the rotary housing, clear of
the hub retaining clip (11). If not, the hub retaining clip is
not fully inserted properly.
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 78 and helps to minimize health hazards or
cross contamination.
1. Allow all chemicals to drain from the TankJet 78. When
using the TankJet 78D in a horizontal orientation, it is
recommended to reorientate nozzle to vertical position to
allow complete drainage.
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.
