Description
During normal daily use aircraft, toilets carry solid and liquid wastes that form limescale, calcium and other deposits throughout the system. Callington Unblock-S has been specially formulated to deal with these build-ups and help maintain a fully functioning toilet system.
Application
Callington Unblock-S is suitable for both vacuum and re-circulating toilets. It is powerful enough for deep soaks during engineering checks and can also be used diluted in a regular cleaning cycle.
Directions for Use
For vacuum toilets – general maintenance: Add Unblock-S neat for dilution with clean water from the flushing system. Crushed ice is not required to improve Unblock-S. Using instructions:
- Start the process at the most forward lavatory by putting 2 litres of Unblock-S down each toilet.
- Flush the toilet once.
- Complete this procedure for all toilets on the aircraft.
- Allow the cleaning solution to remain in the system for 2-4 hours.
- When the cleaning operation is complete add fresh water then flush/backwash to clear newly removed waste and Unblock-S.
- Empty the waste tank(s) to maintain full capacity and minimize weight.
Re-circulating toilets general maintenance: Use Unblock-S at 50/50 dilution with clean water. Crushed ice is not required to improve Unblock-S.
