Removing Existing Fan

Step 1. Ensure the unit is powered off. 
Step 2. Unscrew both Lids. Note that 9 of the lid screws are for the heatsinks and should not be touched. Also note that 2 of the screws are shorter (4mm) these should be reserved for the back lid.
Place all screws in a small cup.

Step 3. Inside the metalwork are some loose metal spacers called shims. These are bespoke heights and should not be disturbed. Place tape along the gap of the side arm, ensuring that no shims fall out. Then, balance the unit on it’s side.

Step 3. (Optional) Check continuity using a multimeter to confirm no shorts.
Step 4. Ensuring that no shims fall out, balance the unit on it’s side.
(tape can be used to prevent any shims from falling out of the side arms).
Step 5. Install the two silver screws into the base plate. Lay the unit flat.

Testing and Reassembly

Step 1. Power on the unit to test the fans. Wait until you hear 6 relay clicks to indicate the unit has booted up.
Step 2. Using a hot air gun, blow air on to the temperature sensors and see if the fan blades spin on each bank. Depending on air temperature it should take up to 5 seconds to start spinning. If the fans do not spin, check the FFC connector is seated correctly.
