XBOXER XBC ECOSMART ADAPT (TREND) CONTROL (AT)
17.0 Maintenance
It is recommended that PPE is always used during the maintenance of
Air Handling Equipment – gloves, eye shields and respiratory mask.
IMPORTANT
Isolation - Before commencing work, make sure that the unit and
Nuaire control are electrically isolated from the mains supply.
In some Ecosmart units and in some third party controls, variable speed
drives (inverters) are used to provide fan speed control. After the fan is
isolated, allow at least 5 minutes for the capacitors in the inverter to
discharge before commencing any work on the unit.
17.1 Dampers
Regularly check that the damper blades move freely.
17.2 Filters (4 x G4 Fitted as standard)
Disposable filters should be changed when an appropriate pressure
drop is achieved.
17.3 Heating Coils
Coils should have their finned surface examined for accumulation of
dirt, lint and biological contaminants or similar.
If necessary, wash down affected areas with a mild detergent solution
and a soft brush. Care should be taken not to damage the finned
surface and any cleaning fluids should be rinsed away with water. A
compressed air line may be used to blow out any solids between fins.
Do not probe the coil fin block with metal objects as damage may
cause leaks.
Drain lines should be checked to ensure that they are unobstructed and
free draining.
Drain pans should be flushed out periodically to remove contamination.
Note: The unit application may require particular attention to this
item – Check with Building Management personnel for details.
17.4 Counterflow Plate Heat Exchanger
The heat exchanger block is normally protected from dust and
contamination by upstream pre-filters. It is possible to clean the unit
with compressed air in the case of dust deposits or by spraying with a
mild detergent solution for grease deposits. Solvents, strong alkaline,
acidic or any products that may be aggressive to aluminium should not
be used. Do not use cleaning water over a temperature of 50 °C.
Drain lines should be checked to ensure that they are unobstructed and
free draining. Traps should be checked that they are fully primed and
functioning.
Drain pans should be flushed out periodically to remove contamination,
and chemical treatments may be used to provide protection between
service visits.
Note: The unit application may require particular attention to this
item – Check with Building Management personnel for details.
