3.2 Extended Storage
1. Indoor storage, if available, is recommended. Actuators can be stored under normal
warehouse conditions up to a year providing they are stored in the original packaging and
orientation with the ambient temperature not exceeding 125 °F (52 °C).
2. Storage conditions should be such that the actuators are protected from excessive moisture,
dirt, re, salt spray, corrosive liquids, paint over-spray, etc. Actuators should not be stored in
an atmosphere harmful to resilient seals.
3. Nothing should be stacked on top of the equipment during storage and the equipment
should be stored away from large moving equipment where damage would result
from contact.
4. After long term storage, the actuator may require the installation of a service kit before
being placed into service.
