IMPORTANT NOTE:
Before carrying out any work on this unit, ensure that unauthorised access is prevented. The unit must
be switched off and isolated, and also locked off if possible. Also check the discharge of the compressor
capacitor.
NOTE: Any maintenance of the refrigerant circuit must only be carried out by a refrigerant competent
engineer. Prior to all maintenance and service on the refrigeration circuit it is advisable to wait a few
minutes after shutdown of the unit before connecting temperature or pressure sensors. Equipment such
as the compressor and piping may reach high temperatures, and the high pressures involved may lead
to serious burns. Please allow sufficient time for these to cool down.
7.2 Maintenance
1. All equipment must be properly maintained in order to provide optimum performance over time.
Poor maintenance can result in the cancellation of the product guarantee. Depending on the product,
maintenance operations consist in the cleaning of filters (air, water), internal and external exchangers,
casings, and the cleaning and protection of the condensate area. Treating odours and the disinfection of
room surfaces and volumes also contributes to the cleanliness of the air breathed by users.
2. After carrying out any maintenance ensure that all component parts are reassembled in reverse order
and correctly fitted. Pay particular attention to the earth screws (B) that secure the outer panels (See Fig.
26).
