Always use the personal grounding strap provided with the kits when you remove the cover (A) and while you replace parts. This strap protects the electronic components from damage due to electrostatic discharge.

Do not lay anything on the control.

Be sure the open side of the control faces up if you lay it down.

Do not twist or force parts. Align them properly as instructed below.
