Safety Precautions and Warnings
Before beginning the installation of any dishwasher, it is essential to follow all safety guidelines provided in the manufacturer’s documentation. These precautions are not merely recommendations but critical steps to prevent accidents and ensure the appliance operates safely over its lifespan.
One of the first and most important warnings is to remove the house fuse or open the circuit breaker before starting the installation. This step is crucial to prevent electric shock. Additionally, never use an extension cord or adapter plug with the dishwasher, as these can create a fire hazard or compromise the appliance's electrical integrity.
Another key safety measure is the proper grounding of the dishwasher. If the house wiring is not already 2-wire with a ground, the installer must provide a ground to reduce the risk of electric shock. In homes with aluminum wiring, the use of UL-listed anti-oxidant compound and aluminum-to-copper connectors is required to prevent electrical degradation and potential faults.
Installers must also be cautious when handling the dishwasher during installation. For example, opening a drawer before the appliance is fully installed can cause it to tip forward. Therefore, it is recommended to hold the drawer handle with one hand and the top of the dishwasher with the other when opening it prematurely. Wearing gloves and safety glasses or goggles is strongly advised to protect against cuts and debris.
Furthermore, the documentation from CAFE Appliances emphasizes the importance of leaving the installation instructions accessible to the consumer and the local inspector, as per building codes and regulations. This ensures that if service is ever required, the installer or technician has access to critical information about the installation process.
