13.0 Maintenance and Troubleshooting
13.1 Cleaning the Unit
Please ensure that no liquid is spilled onto or into the unit. In addition, periodically wipe it clean of dust and other residue that comes
with normal operation of the unit. Use a soft, lint-free cloth and deionized water. Air vents should be vacuumed to remove dust.
13.2 Cleaning the Heated Lid
Make sure the Labnet MultiGene thermal cycler is unplugged and cooled down. To clean the heated lid, slide the lid back on the tracks
until the front black pins align with the two slots, taking care that the Rolleiflex cable is clear. Lift the lid from the front, (be careful
of sharp edges) and flip up. Use mild detergents to clean material from the lid. A cotton free wipe dipped in 70% ethanol will help
remove and residue from sealing tape. Make sure the lid is dry prior to lowering it into the tracks. Once the lid in secure in the tracks
make sure the lid easily slides forward.
13.3 Replacing a Fuse
The fuse is located in the power socket module, just below the power connector. If the unit does not turn on when the power switch is
turned on, then replace the fuse. To replace the fuse:
Disconnect the power cord from the unit.
Remove the fuse drawer with a small-blade screwdriver.
Pull the fuse out of the fuse socket and replace the fuses with one having the correct current rating.
For 100-120V operation: Use 7.0A, 5 x 20 mm, glass tube.
For 220-240V operation: Use 3.15A, 5 x 20 mm, glass tube.
Reinsert fuse into the fuse socket. Reinsert the fuse drawer.
13.4 Changing the Thermal Block
Slide the lid to the furthest point back.
Remove the two plastic plugs and the two screws holding the face plate.
Flip the face plate forward to gain access to the block.
Remove the two screws holding the heating block.
Gently slide the thermal block forward. Once it is clear of the frame, remove it from the unit.
Slide the new block into place, and connect the plug.
Gently slide the block until the two screw holes are lined up.
Replace the two screws and plugs.
Shut the face panel, and secure it with two screws.
