21 - MAINTENANCE
Make sure that the unit has been disconnected from its power source before any maintenance.
Note down the operating readings and perform the checks indicated in the above table at least twice a year and each time a unit
is commissioned for seasonal use.
● To prevent accidents and ensure proper ventilation of the condenser, keep the unit and the space around it clean and free of
clutter.
● Check the coil for dust, fibres, leaves and anything else that may collect on it. Clean it with a soft brush or a vacuum
cleaner. It can also be cleaned using a water spray:
- at low pressure
- in the direction of the fins
- in the opposite direction to the air
● Periodically clean the refrigerant pipes
● Make sure the mountings and all components are securely tightened: pipes, couplings, panels, etc. in order to prevent
vibrations that may damage the refrigerating circuit and cause refrigerant leaks.
● The electrical connections must be tightened before initial commissioning, as well as a few weeks after this, prior to each
restart in the case of seasonal operation and at least once a year.
To ensure your unit runs smoothly and to obtain service under the warranty, take out a maintenance contract with your
fitter or an approved maintenance company.
