01
Account for the actual cleaning duty
- The reference covers Toftejorg and Gamajet rotary jet heads; do not apply their schedules automatically to every tank-cleaning device.
- Heavy soiling and recirculated CIP liquid containing abrasives or particles require closer attention than light-duty cleaning.
- Use the machine manual for strainer recommendations and for the exact inspection, minor-service and major-service kits.
02
Keep Toftejorg intervals model-specific
- SaniJet 25 uses separate inspection, minor-service and major-service milestones. They are not interchangeable.
- For SaniJet 20 Media, the reference distinguishes ordinary tap water / common CIP solvents from special media such as WFI.
- Legacy TZ machines may require a conversion or replacement assessment. The source directs these questions to Alfa Laval.
03
Rinse, inspect and store Gamajet heads
- Rinse with clean water after each use to remove residues that could harden or attack O-rings during storage.
- Store with the inlet connection facing down, as described in the reference.
- Inspect initially after 100 operating hours. Use the model-specific follow-on interval only if components are acceptable, accounting for severity of use.
- Bearings, bushings, seals and O-rings are wear parts. The source recommends group replacement where possible; replace a worn bearing or seal and its mate together.
Service planning at a glance
Reference intervals and checks from PDF pages 19–22. Verify against the instructions for your unit.
| Component / check | Reference timing | Planning note |
|---|---|---|
| SaniJet 25 — inspection kit | 200 h / yearly; 600 h / third year | Milestones shown in the source table. |
| SaniJet 25 — minor / major kit | 400 h / second year; 800 h / fourth year | Minor at the first milestone; major at the second. |
| SaniJet 20 Air — service kit | 300 h / yearly | Confirm the specific machine manual. |
| SaniJet 20 Media — service kit | 300 h; 150 h with special media | 300 h for tap water / common CIP solvents; 150 h for media such as WFI. Table also gives yearly at 300 h. |
| TJ40G — minor / major kit | Minor: 500 and 1,000 h; major: 1,000 h | Separate kit rows in the source. |
| TJ20G / TZ-89 | 500 h / 300 h respectively | Working-hour intervals. |
| Gamajet — initial inspection | 100 h | Follow-on schedule depends on model and condition. |
| GJ 7 | 100–200 h after initial inspection | Subject to severity of use. |
| GJ A6, GJ 5, GJ 8, GJ 9 | 300–500 h after initial inspection | See page 22 for the full model matrix. |
| GJ A2, GJ BB / GJ 4, GJ 10, GJ PF | 400–600 h / 500–700 h | Two separate model groups. |
| GJ PF FT | 600–800 h after initial inspection | Confirm actual operating conditions. |
Selected model schedules are summarised here. Page 22 lists two follow-on bands for GJ A8 (300–500 h and 500–700 h); confirm the applicable interval rather than choosing one arbitrarily. Consult pages 20–22 for other models.
