Rational COMBIMASTER Operating Instructions

- 8 -
Danger - High Voltage
- Inspection, maintenance and repair work must only be carried out by trained technicians.
- The unit must be switched off at the mains for cleaning (apart from manual cleaning) and for
inspection, maintenance or repair work.
- If the unit is installed on casters (mobile), freedom of movement must be restricted so that power,
water and drainage pipes cannot be damaged when the unit is moved. If the unit is moved, make sure
that power, water and drainage lines are correctly disconnected. If the unit is returned to its original
position, make sure that the retention device, energy, water and drainage pipes are correctly attached.
- Your unit should be serviced by an authorised service partner at least once a year to ensure that it
remains in perfect working order.
Care
Care, inspection, maintenance and repair
Your unit must be cleaned every day to maintain the high quality of the stainless steel, for hygiene reasons
and to avoid operating faults. To do this, follow the instructions in the “Manual cleaning” section..
Warning:
If the unit is not cleaned or is not cleaned well enough, deposits of
grease or food residues in the cooking cabinet may catch fire - Risk of fire.
- To avoid corrosion in the cooking cabinet, your unit must be cleaned every day, even if it is only operated in
“Moist Heat” (steaming) mode.
- Apply vegetable oil or grease to the inside of the cooking cabinet at regular intervals (every 2 weeks or so)
to prevent corrosion.
- Do not use a high pressure cleaner to clean the unit.
- Do not treat the unit with acids or expose to acid fumes – this will damage the passivated coating of the
nickel-chromium steel and the units might discolour.
- Only use cleaning agents made by the unit’s manufacturer. Cleaning agents from other manufacturers may
cause damage and invalidate the warranty.
- Do not use scouring products or scratchy cleaning agents.
- Daily cleaning of the cooking cabinet seal with a non-abrasive cleaning agent will extend the service life.
- Remove and clean the incoming air filter once per month (see Maintenance).
