Retro-fitting cooling

A cooling system can be retro-fitted with relatively little difficulty. This first involves dismantling the
rear wall of the housing:
Switch the equipment off and withdraw the mains cable.
-
Open the incubation chamber door
-
- Remove the four caps covering the holders in the back wall.
- Remove the four holders by turning them 90
until the embossed arrows point outwards.
The back wall is now pushed outwards, so releasing the holders. Eventually, the holders can
-
be loosened with a screwdriver.
IMPORTANT: NEVER WORK ON THE EQUIPMENT WHEN IT IS STILL CONNECTED TO
MAINS POWER!
Fig. 14: Removal of the back wall involves uncovering 4 holders by removing their covers and turning them
anti-clockwise. The back wall can then be pushed out.
11.4.1 Retro-fitting an external cooling cool
After removal of the back wall (see Chapter 11.4) fit the new back wall with the cooling coil and
control valve already mounted in position.
- Put in the new back wall with cooling coil, taking care not to trap the connecting cable to the
control valve.
Use a flat-head screwdriver to turn the 4 holders for the back wall 90
-
place.
Plug the connection cable from the control valve into the electronics box (see wiring
-
diagram).
- Insert the "cool print".
