If the TFA STS is not to be immediately installed and energized, it should be carefully stored in a warm, dry
environment, preferably a heated building with air circulation and a uniform temperature to prevent
condensation. The TFA STS should be stored in its factory protective coverings and should be kept free of
contamination.
Storage temperature range must be within these limits: -40° to +80°C.
