Specify the complete electrical configuration
Voltage is only one part of the requirement. Confirm frequency, plug type, power-cord length, rated power, grounding arrangement and the product label. The supplied manual and carton information should refer to the same configuration.
Keep configurations separated
When one purchase order includes multiple electrical versions, use distinct model references or clear suffixes. Components, labels, manuals and cartons should be controlled so that the wrong version cannot be packed for a market.
Review the installation environment
The buyer should consider outlet position, bathroom electrical practice, water exposure and access for disconnecting power. Product documentation must be evaluated against the requirements of the destination and the exact model being supplied.
Validate samples in the correct version
Do not approve a 220–240 V project using a sample built for a different voltage simply because the function list is similar. Test the intended configuration, including plug, cable, remote, labels and recovery after a power interruption.
Control documentation and changes
Maintain a version record connecting the model, key components, software where relevant and market documents. Any electrical component change should be reviewed before it enters a repeat order. This discipline protects both compliance work and after-sales support.
