9. STORAGE
The ACTUATECH actuator has been packaged to provide protection during shipment, however, it can be damaged in transport. Prior
to storage, inspect the actuator for shipping damage. Keep the actuators in their original packing box during storage.
It is recommended to keep the actuators in a clean and dry environment at temperatures between -10°C and +60°C until ready for
use.
The actuator has two air ports, which are closed by labels for prevent liquids or others material to entering in the actuator during
storage.
If the actuators are to be stored for a long period of time before installation, it is recommended to stroke them periodically to prevent
setting of the seals.
WARNING
Keep the actuator in its original box until the installation, and store it indoors, in dry and clean environment, at temperatures
between -10°C and +60°C to protect them from humidity and dust.
