Cleaning the Coils
Coil cleaning and disinfection should be performed along the entire coil area.
Note
Before you begin, check that the electrical compartment door is closed and
sealed, and that the unit is disconnected from the drainage system.
Caution
An adequate safe distance from the coils must be maintained during the
cleaning process to ensure the coil fins will not be damaged.
Warning
Steam cleaning must only be performed by a qualified person to prevent
damage to the coil cooling fins.
To clean the external coils:
1.
Clean the evaporator and condenser coils surface by gently blowing the
dirt out from behind the fins with low-pressure compressed air.
To prevent any damage to the fins, it is best not to aim the air nozzles
directly at the coils. Alternatively, gently vacuum clean the coils.
2.
Gently wipe the coils with a semi-wet cloth.
3.
Further cleaning can be done by steam or by using a cleaning substance
meant for cleaning air conditioning systems. For example, ACE® Foam N'
Clean® Coil Cleaner
4.
After cleaning, leave all unit doors open to let all internal parts dry.
5.
Check the electrical compartment to ensure nothing got wet and that
there is no moisture.
To clean the internal coils:
Accessing the internal coils requires dismantling and removing the fan on the
roof of the unit. Access to the coils is from the top of the unit. Otherwise, only
the external half of the unit can be accessed.
Follow the above procedure for cleaning the internal coils.
