# Mount the 5mm LED

If you don't have a PCB for the illumination, you can mount a 5mm LED instead.

The 5mm LED mounts to the lid of the condenser, not in the same place as the PCB.

## For this section you will need:

### Tools

- 1 #1 pozidrive screwdriver

### Printed Parts

- 1 condenser LED holder

### Electronic Components

- 1 LED assembly

### Mechanical Components

- 2 No 2 6.5mm self tapping screws

## Step 1: Mount the LED

- Push-fit the LED assembly into the condenser LED holder printed in the first step.
- Secure the LED holder onto the lid of the condenser with two No 2 6.5mm self tapping screws using a #1 pozidrive screwdriver.

## Step 2: Mount the diffuser

- Fix the diffuser onto the condenser, as described in the main condenser page, omitting the board spacer and PCB.
- Alternatively, PTFE tape can be used on the LED, as in previous versions of the instructions, instead of the diffuser.
