Section 7: Maintenance
Maintenance Procedures
The Sacksafoam I unit requires no maintenance other than cleaning. Daily, after use, and prior to storage,
the sack should be flushed out with clean water. Clean off the outside of the sack to remove any residual
foam.
Flushing Procedure
1.
Insert a water hose into the fill port and run the dispenser pump until the water runs clean.
2.
Wash out the side of the bladder until clean.
3.
Remove the drip tube to drain any residual foam.
Pump Maintenance
Check wires and connectors periodically to be sure corrosion is not adding additional resistance to the motor
circuit and causing a low voltage condition at the motor. Low voltage can inhibit the motor from starting
and can cause a fuse to blow. Full voltage should be available to prevent motor damage. At the end of each
fire season, the pump should be flushed with clean water as foam will dry out over time causing the impeller
to stick. Some water can remain in the pump while in storage. Also, if the pump is idle for long periods of
time, the impeller may stick to the pump body, preventing motor rotation and causing blown fuses. To cor-
rect, remove the end cover and the impeller, clean the body and impeller, then lubricate with water or a small
amount of grease before re-assembly.
If the pump is stored in freezing temperatures, drain it by loosening the end cover screws, allowing any foam
or water to drain completely. A service kit or spare impellers should be carried onboard to be assured of
pumping capability. Spares kits are supplied with each pump and additional kits can be ordered from SEI
(see parts list).
Important Note
Proper cleaning of the sack prior to storage will increase the life span of the unit.
Caution
Residual foam will form a waxy substance that can prevent proper operation of the Sacksafoam.
