10. For T-21 and T-22 transducers, place the retainer over the transformer assembly. Ensure the retainer threads are aligned correctly and hand-tighten. Use a 1 1/8” wrench and turn clockwise until the transformer assembly is fully seated in the transducer holder. Note: Do not over tighten the retainer.

11. Reconnect the transducer chordset to the transducer holder or the retainer if installing T-21 or T-22 transducers. The internal connector of the transducer chordset is keyed and will only go on one way. Secure the transducer cabling nut by turning clock-wise. Ensure the cable nut threads are correctly aligned.
