Locate the 2 into 1 adapter and the locking collar from the kit.

Install the collar onto the 2 into 1 adapter as shown in Figure 1.

Install the 2 into 1 adapter into the hotend until you feel resistance.

DO NOT OVERTIGHTEN when screwing the adapter into the hotend. You want to install it until you feel resistance, then go up to 1/2 turn beyond that but NO FURTHER.

See Figure 2 to see approximately how much the adapter will be screwed into the hotend.

Secure the adapter to the hotend by tightening the locking collar down to the circuit board and use a pair of pliers to secure it tight. See Figure 3 to see the locking collar tightened down.
