General assembly instructions

Before assembling the CX212x knob cylinder in a fire/smoke-resistant door, please recheck the fire certification to ensure conformity.
Ensure that the sealing affixed on the door does not hamper proper operation of the CX212x.
Ensure that the knob cylinder projections do not obstruct the free swing of the door.
As electronic knob cylinders are supplied in a completely assembled state as standard, it may be necessary to perform the steps for disassembly, asdescribed in chapter 4.3, before mounting.
To activate the knob module, insert the batteries or remove the battery tag, if present, and close the casing (see chapter 7.2.1 Changing batteries).
Before mounting the knob module, always check that all components move freely.
Carry out the assembly with the door open.
Only for cylinders supplied as single components: During initial installation, put in 1 to 2 drops (max. 0.1 ml) of a non-resinous oil in the cylinder body.It should not be sprayed directly into the cylinder body with a spray can.
