Don’t let your “Sparky” talk you out of this to save a few bucks. You are paying the bill so you dictate what is done, and check to see that it has been done before you pay for the job!
This compressor represents quite a monetary outlay, and you are buying it because of its great performance.
Why compromise this performance with a poor installation?
Do it right, do it once!
It goes without saying that the wires need really good insulation, especially where they pass through the firewall of the vehicle. You will need to inspect the area carefully. In late model vehicles there is usually a rubber bootie bonded to the firewall that is designed to allow cables to pass through without drilling any holes in the metal and offers extra protection and insulation.
If your vehicle has booties use them!
If not you will need to insert a rubber grommet of sufficient size to accommodate the heavy cable in a sheath of “convoluted tubing” insulation into the firewall. It is good practice to sheath the entire length of cable in a convoluted sheath. Use cable ties to attach the cables to existing wiring when you are happy that the wires are correctly positioned to prevent them from bouncing around in the door channels under heavy vibration associated with “Off-road driving”. The aim is to prevent chaffing of the insulation and a subsequent short circuit to the body of the vehicle. To achieve this, cables must be firmly attached to tie points within the channels.
In the event of a short circuit you must have the protection of a fuse in the circuit that will melt quickly and prevent any further current flow.
We supply a 250 Amp fuse with every 12 volt compressor and a 150 Amp fuse with every 24 compressor. Do not use your compressor without the fuse installed!
The second little problem is that we must be able to disconnect the electrical cables from the compressor to close the drawer after use.
This means that we need a high capacity plug assembly close to the drawer system so that we can connect and disconnect the power easily whenever we need to use the compressor.
