Determining the correct BAYQSTK kit, either BAYQSTK300B or BAYQSTK301B, for your unit is straightforward. The BAYQSTK300B kit is compatible with 4WC** and 4TC** model units, but excludes the 4TCA, 4WCA, and 4YCA models. Conversely, the BAYQSTK301B kit is designed for 4YC**, 4DC**, 4TCA, 4WCA, and 4YCA units. To ensure you select the appropriate kit, locate your unit's model number. Consult the installation guide or the product specifications to confirm the kit's compatibility with your specific model. If your model number is listed under the compatible models for the BAYQSTK300B, that is the kit you should order. If your unit is listed under the BAYQSTK301B compatible models, then choose that kit. Choosing the correct kit is crucial for the proper function and installation of your heating and air conditioning system.
