• If the 9900 Base Unit will be mounted using the accessory wall mount kit (3-9900.392), install plug-in modules fi rst.
• If the Direct Conductivity/Resistivity Module or the 4 to 20 mA Output Module will be included in your unit, install the HCOMM module fi rst, then install the other module over the H COMM module
