Equipment Inspection and Storage
Once you have received the transfer switch, inspect
it for any damage. This includes damage to the enclo- sure, power panel, control panel and wiring harness. If any damage is found or suspected, file a claim as soon as possible with the carrier and notify the nearest GE Zenith representative.
Before installation, it is necessary to store the transfer switch in a clean dry place, protected from dirt and water. Provide ample air circulation and heat, if neces- sary, to prevent condensation.
