1. Preparation

Take a few minutes to read any instructions that come with the pack. Be careful to heed warnings about not placing materials directly over ventilation holes, or any moving parts or other components that will require airflow for cooling.

Turn any mains power supply off and unplug any power leads from the mains supply. The case should be fitted not connected to any power supply.

2. Fit the Case Roof

Remove any Power Supply Unit (PSU), and turn the case upside down. Remove the top 5¼-inch drive bay cover to allow easier access to the front of the case roof (see below).

Peel back a portion of the self-adhesive backing paper, and position the front narrow section of the roof part towards the front of the case as far as possible. Then remove the remainder of the backing paper and fit the remaining material PRESSING FIRMLY when into position.

3. Fit Drive Bay Blanking Plates

Fit the small backing pieces of acoustic composite behind the case front 3½ and 5¼-inch drive bay covers. The drive bay covers can be reached by prising off the front of the case. To do this, press the tabs either side of the front cover located towards the base; and lift the cover off (with a forward and up motion).

4. Fit Acoustic Foam Block on the Case Floor

Fit the almost square acoustic foam block under the Hard Disc Drive (HDD) cage on the case floor. This is a pressure-fit, and just pushes into the space.

This block will help to direct cool air from the front of the case over the installed hard disk drives.

5. Fit Case Floor Acoustic Composite

Fit the floor piece in the bottom left hand corner under the 'open door switch' (take care - this is fairly delicate), then the back of the floor under the expansion slots.

Position materials lightly at first - so they can be repositioned if necessary.

Once in position, position the remainder of the sheet and PRESS FIRMLY (this 'sets' the adhesive) over the entire sheet paying attention to 'molding' the sheet over the case feet.

6. Add Acoustic Foam Blocks (Optional)

Pressure-fit the acoustic foam blocks into any spare 5¼ and 3½-inch drive bays. Acoustic blocks are also provided to fit into any spare locations in the HDD cage.

Take care not to place any acoustic foam block immediately against any devices that may not tolerate being isolated from cool air circulation (such as a disk drive).

7. Add Acoustic Composite adjacent to Expansion Card Slots

Attach the shaped acoustic composite material piece into the space adjacent to the expansion slots. Make certain the material does not cover the door locking screw hole. The acoustic material can be placed against the floor acoustic covering.

8. Fit Side Panel Behind the Motherboard

Unscrew and remove the side panel behind the motherboard.

Fit the sheet to the hinge edge first pressing lightly. Check there is an 18mm gap between the material and the the rear edge of the door to allow it to close. When the position looks correct, fit the remainder of the sheet. PRESS FIRMLY over the entire sheet to set the adhesive.

9. Fit Main Door Panel

Fit the sheet to the hinge edge first, leaving a similar 18mm gap at the rear of the door, and press lightly.

When the position looks correct, fit the remainder of the sheet. PRESS FIRMLY to set the adhesive.

10. Add the Air Filter (Optional)

The air filter can be installed by removing the lower front grill section of the case. This is achieved by lifting the case up slightly and locating and pressing the tab under the front of the case grill. Once detached, install the washable air filter in the void behind the front grill, and replace the unit.

Remove the air filter and wash regularly to maintain adequate airflow. Do not use the air filter if maximum airflow is required for cooling purposes.

14. Important!

• ONLY position the materials as directed in the fitting directions and as depicted in the graphics above.
• DO NOT cover the ventilation holes at the rear or the front of the case with any materials (except the washable air filter if installed).
• DO NOT position materials inside the case in such a way that may inhibit the correct functioning of any internal components, especially cooling fans, disc drives and moving parts. These components require adequate space and ventilation. Whilst every care has been taken to produce a set of templates that will be appropriate for the majority of component configurations, it is the responsibility of the machine builder to position the materials appropriately to facilitate normal functioning of internal components.

Fan Mount Fitting Instructions

1. Remove the 'hold-fast' fan brackets from inside the case. To do this, unscrew the retaining screws.
2. Thread 4 black fan mounts from outside the case through the larger of the two case fan mounting holes. Gently pull the fan mounts into position, so they are held in place by the case and face inwards.
3. Position the 120mm case fan inside the case (remember to check the fan airflow direction at this point!), so that the mounting holes on the fan match up to the 4 fan mounts, and they poke through the fan mounting holes. Starting with the mounts furthest away from you, gently pull the fan mounts through the fan mounting holes, until they hold the fan in position with the arrowhead.
4. The fan will now operate in physical isolation from the chassis, significantly reducing any vibration transmission from fan motors and moving parts.

Note: The 8 Soft Black Fan Mounts that come with the AP C6607 acoustic materials kit are NOT suitable for other cases (except the Compucase 6A19) - as they have been designed specifically to fit the AC C6607 case.
