10.1 Corrective maintenance
The FISAIR desiccant rotor dehumidifier is a highly reliable piece of equipment, and so does
not require very demanding corrective maintenance.
The motors used by the unit may require repair/replacement due to mechanical or electrical
malfunctions. It is not within the scope of this manual to cover these, as any suitably qualified
maintenance technician will have sufficient knowledge to deal with this.
The electrical reactivation battery may need to be repaired or replaced in the long term, as
will any conventional air heating component.
The filters will have to be replaced or cleaned regularly in order that the unit's performance
and power consumption are not impaired.
Minor components such as the rotor drive belt and electrical board components may need to
be replaced in the long term.
It is the customer’s decision whether or not it is more convenient
to keep a store of replacement parts, depending on the lead time to procure them from
distributors.
