8. Maintenance
8.1. Cleaning
8.2. Replacement of fuses
The case can be cleaned with a damp cloth after disconnection from the power supply.
Do not use solvents. The immersed parts can be cleaned using proprietary heating
element cleaners.
CAUTION: these may be toxic - follow the cleaner manufacturer's instructions.
Before using any decontamination or cleaning method other than recommended, check
with our Service Department, or in other countries with our distributor, that the proposed
method will not damage the equipment.
The removable grill enables easy access to the condenser for cleaning. Cooling power
will be reduced if the fins become clogged with dust.
Examine monthly and, if necessary, use a vacuum cleaner nozzle and soft brush to
remove the dust.
Fuse replacement should only be carried out by a competent person.
Disconnect the unit from the power supply socket. Remove the IEC power plug from the
rear of the unit. Press down the drawer catch (see Fig 3). Pull out the fuse drawer,
check and replace with the correct value fuse:
Push back the drawer and replace the IEC PLUG.
On 110V versions where there is no IEC connector, there are however two fuse holders
which can be unscrewed to access the fuses.
