7. ELECTRICAL INSTALLATION
Electrical Installation of the Fan
The electrical installation must be performed by a certified electrician in accordance with the appropriate national and local electrical codes.
WARNING
ANY VIOLATION OF ELECTRICAL WIRING CODES COULD JEOPARDIZE THE AIRSTREAM WARRANTY.
Check the type of electrical service present, and make sure the fan to be wired is manufactured to operate on the electrical service. The table on page 7 entitled “Fan Model Specifications” indicates the electrical service the fan is designed to utilize in the column labeled “Motor Phase and Voltage”. The electrical service must match this specification.
The components to connect the electrical service to the fan need to be sized for the electrical service present. The charts below illustrate the sizing information for single phase 230 volt, three phase 230 volt and 460 volt respectively. Use the appropriate information and size the following electrical service components:

Transformer
The transformer size for the fan only is indicated in a KVA rating. Example: For a 24" fan the first chart would be used. The KVA rating for the 2 horse power motor is 3.5 KVA. This KVA rating is for the fan only. Your electrician will need to add the KVA requirements for the other electrical components of the system in sizing the transformer.
