• Make sure that the gaskets are not damaged.
• Make sure that the electrical cables are not damaged.
• Make sure that the electrical cables agree with the national electrical code.
• The cables are in a loop in front of the device 1 so water does not go into the housing.
• Tighten the cable feedthroughs 2.
