15. Maintenance
WARNING Electrocution
f
Prior to commencing any service or cleaning work,
isolate the appliance across all poles from the
power supply.
Following disconnection from the power supply, parts of
the appliance may remain energised for 5 minutes until
the inverter capacitors have discharged.
Note
When you open the appliance, check the sealing tape.
The sealing tape is required for generating the necessary
negative pressure.
f
Replace the sealing tape if required.
We recommend a regular inspection (to establish the current con-
dition of the system), and maintenance if required (to return the
system to its original condition).
f
Check the discharge aperture on the top of the appliance
and the intake aperture on the side of the appliance (visual
check). Remove any contaminants and blockages immediate-
ly.
