Storage
The unit must be properly prepared for storage. If the unit is being stored for the winter the water must be
drained to prevent freezing and damage to the components.
Due to varying water quality and the use of “gray water” the water should also be drained from the unit if the unit
will be out of service for an extended period of time.
Preparation for Storage.
1. With the engine off and the key removed, rotate the engine until resistance is felt, than continue to rotate the
engine an additional 1/4 turn. This opens the cycling valve.
2. Using the appropriate fittings, connect a compressed air supply to the water inlet of the machine. (Maximum
pressure 150 PSI - Minimum 90 PSI).
3. Remove one aeration nozzle from each end of the nozzle manifold .
(see service bulletin Specialty #08-07.). The spring check in the nozzle prevents water from being forced
out by the air pressure. Removing the nozzles insure that the pump and manifold is drained.
4. Let the compressed air flow through the system for three minutes.
5. Temporarily open the high-pressure drain valve and the spray wash valve if equipped.
