* Installation
The retrofit control kit will work with any self contained marine air conditioner. But it is not a plug and play type. It needs a professional Electrician or an HVAC technician to make the installation. All the electrical components of the existing air conditioner ( compressor, fan motor, reversing valve, pressure switches and the pump) must be identified. Their cables must be identified one by one and re-connected to the new control board. In case the existing unit has a separate run and start capacitor for the compressor, it will still work but it is more complicated to do the wiring. Our retrofit control kit is made for 3 speed fan motors ( it gives three different relay outputs for a motor with 3 winding). In case the old unit has a single speed motor, you will not have a speed control function with the new control system. Please download the installation schematics and make sure that you ( or the installer) understands it.
