Choosing the correct kit, either BAYQSTK300B or BAYQSTK301B, is essential for your unit's proper function. The BAYQSTK300B kit is compatible with 4WC** and 4TC** units, but it is not compatible with 4TCA, 4WCA, or 4YCA models. Conversely, the BAYQSTK301B kit works with 4YC**, 4DC**, 4TCA, 4WCA, and 4YCA units. To find the correct kit for your unit, locate your unit's model number. Refer to the installation guide or product specifications to confirm the kit compatibility. If your unit model matches the BAYQSTK300B compatibility list, select that kit. If your model aligns with the BAYQSTK301B list, then choose that one. Selecting the right kit ensures a smooth installation and optimal performance of your heating and air conditioning system.
