Cleaning and Maintenance
Important: Before cleaning, the unit should be put into standby and then the power supply should be
turned o at the mains. Please do not plug or unplug the unit with wet hands. Only when cleaning has
been completed and the unit is dry should the cabinet be turned back on at the mains.
Suitable P.P.E (Personnel Protecve Equipment) should be worn at all mes.
Regular Maintenance:
> As and when required remove all product from the unit. Clean exterior and interior surfaces with mild
liquid detergent, following the direcons on the pack at all mes. Rinse surfaces with a damp cloth
containing clean water. Never use wire wool, scouring pads/powders or high alkaline cleaning agents i.e
bleaches, acids and chlorines as these may cause damage.
> Condenser Cleaning:
This should take place on a regular basis or as and when required (4 to 6 weeks) by a competent/trained
personnel.
Use a so brush or vacuum cleaner to remove dirt/dust. If there are any stubborn grease deposits le on
or through the condenser, call your supplier to carry out a full service (this is normally chargeable). Failure
to maintain the condenser may invalidate the warranty of the condensing unit and cause premature
failure of the motor/compressor.
Do not use a wire brush to clean the condenser. Vacuum or brush the air lter (where ed).
> All gaskets should be inspected on a regular basis and replaced if damaged. To clean, wipe with a
warm damp soapy cloth followed by a clean damp cloth. Finally thoroughly dry.
