DESICCANT ROTOR
The desiccant rotor is maintenance free, however, if it becomes blocked with dust (e.g. if it has been running
without inlet air filter) it can be cleaned by vacuum cleaner or low pressure compressed air.
HEATER BANK
The PTC heater bank is maintenance free however, if it becomes blocked with dust (e.g. if it has been running
without inlet air filter) it can be cleaned by vacuum cleaner or low pressure compressed air.
OVER-HEAT PROTECTOR
In the event of total airflow loss, the over-heat protector will operate. If this happens
it will need to be manually re-set after the airflow is restored.
To reset, push the red button (R) down.
DESICCANT ROTOR DRIVE
The desiccant rotor is driven by a geared motor via a toothed belt. The rotation
speed is approximately 20 RPH. It can be seen turning during operation through
the air outlet duct. If it appears to be slow or sticking, the belt can be re-tensioned
using the 4 mounting screws @ ''A''.
