14.0 MAINTENANCE
It is recommended that PPE is always used during the maintenance of Air
Handling Equipment – gloves, eye shields and respiratory mask.
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.
14.1 DAMPERS
At regular intervals check that the blades move freely.
14.2 FILTERS (4 X G4 FITTED AS STANDARD)
Disposable filters should be changed when an appropriate
pressure drop is achieved.
14.3 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.
14.4 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 50 deg 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.
14.5 FANS AND MOTORS
Fan bearings should be manually checked at regular intervals for condition.
Standard fan bearings are supplied as ‘sealed for life’ and have an anticipated
life of 40,000 hours.
Motors have an enclosed bearing housing and are pre-greased
for life. Check all fixings are secure.
14.6 GENERAL
Inspect all internal and external surfaces to check for corrosion or peeling of
painted surfaces.
Thoroughly clean affected areas with a wire brush, apply a coat of zinc rich
primer or similar, and re-touch with suitable finishing paint. Ensure tightness
of all nuts, bolts, and fixings.
Check all components for general condition.
