Cleaning
The front panel membrane conceals and protects switches and LEDs. It may be wiped clean using a
damp cloth. Be sure to disconnect the unit from the mains before cleaning, and do not use any
abrasive cleaners or organic solvents.
Periodic testing
Check the mains lead and plugs at both ends for any damage.
Periodically check the earth bonding and insulation, by performing a Portable Appliance Test (PAT).
Most schools and local authorities have a regular schedule for such testing.
Check the action of the electronic cutout, by short circuiting the power supply output (check dc and ac
outputs separately) using a short 4mm plug lead.
Check that the fuse in the mains plug (5A recommended) and the two fuses (active and spare) in the
IEC socket on the back panel are all of the correct rating.
