II.10.1.4 Micro-channel coil with E-coating treatment
(MCHXE accessory)
Procedures to clean the micro-channel coils with ElectroFin®
coating
The following cleaning procedures are recommended as part of the
routine maintenance for the micro-channel coils with ElectroFin®
coating. Documented routine cleaning of micro-channel coils with
ElectroFin® coating is required to maintain warranty coverage.
Remove Surface Loaded Fibres
Fibres and filth accumulated on the surface must be removed before
proceeding with water rinse in order to avoid further air flow restrictions.
If the coil side opposite the air inlet cannot be washed, eliminate the
fibres and dirt accumulated on the surface with a vacuum cleaner. If a
vacuum cleaner is not available, a soft non-metallic bristle brush may
be used. In either case, the tool should be applied in the direction of the
fins.
Inserting the cleaning device or the brush between the fins can easily
damage the surfaces of the coil (bend the edges of the fins).
NOTE: using a jet of water, such as a garden hose against the coil
pushes fibres and dirt inside the appliance, thereby making the cleaning
process more difficult. Surface loaded fibres must be completely
removed prior to using low velocity clean water rinse.
Periodic Clean Water Rinse
A monthly clean water rinse is recommended for coils that are applied
in coastal or industrial environments to help to remove chlorides, dirt
and debris. While rinsing, it is extremely important that water
temperature is below 54°C and pressure is less than 62 barg in order to
avoid damaging the edges of the fins. High water temperature (not
above 54°C) reduces surface tension, increasing capacity to remove
chlorides and filth.
Routine Quarterly Cleaning of ElectroFin® coated coil surfaces
A quarterly cleaning is essential to extend the life of the ElectroFin®
coated coils, as well as necessary to ensure the warranty is valid.
Cleaning the coils must fall under the scheduled routine maintenance
procedures for the unit. Failure to clean the coils with the ElectroFin®
coating shall cause the warranty to become null and void, thereby
reducing the efficiency and duration in the room. As for regular quarterly
cleaning, start treating the battery with the designated approved
detergent (see the list of approved products in the recommended coil
detergents section). After cleaning the batteries with the designated
detergent, use the approved dechlorinating agent (in the section with
the recommended dechlorinating agents) to remove soluble salts and
rinse the unit.
Recommended coil detergent
The detergent shown here below, provided it is used in accordance with
the manufacturer's mixing and cleaning instructions reported on the
container, has been approved for use on ElectroFin® coated micro-
channel coils to remove soil, mould, dust, soot, grease residues, down
and other particulates:

CHLOR*RID DTS™ must be used to remove soluble salts from the
ElectroFin® coated battery, though by carefully following the directions
provided. This product is not intended for use as a degreaser. Any
grease or film of oil must be removed using the approved detergent,
before proceeding with cleaning
1. Eliminate the barrier - Soluble salts adhere to the substrate. For the
effective use of this product, the product must be able to come in
contact with the salts. These salts may be beneath any soils, grease or
dirt; therefore, these barriers must be removed prior to application of
this product. As in all surface preparation, the best work yields the best
results.
,2. Apply CHLOR*RID DTS - Apply CHLOR*RID DTS directly on the
substrate. Using a sprayer or a conventional gun, uniformly apply on the
substrate a quantity of product sufficient to completely wet the surface,
without leaving out any part. The chosen method is not important, what
matters is covering the entire area to be cleaned. After the substrate
has been thoroughly wetted, the salts will be soluble and is now only
necessary to rinse them off.
3. Rinse - It is recommended to use flexible hose, since the pressure
washer may damage the fins. It is recommended using potable water
for rinse, even if it is possible to use a lower quality water by adding a
small quantity of CHLOR*RID DTS. Follow CHLOR*RID International,
Inc recommendations regarding the use of lower quality rinse water.
ATTENTION:
Harsh Chemical and Acid Cleaners
Aggressive chemicals, bleach for household use or acid detergents
must not be used to clean ElectroFin® coated coils for indoor or outdoor
use because they are very difficult to rinse away and can accelerate the
corrosion process by damaging the ElectroFin® coating. In the
presence of dirt under the surface of the coil, use the recommended
detergents as described above.
ATTENTION:
High Velocity Water or Compressed Air
Water at high speed from a pressure washer or compressed air should
only be used at a very low pressure to prevent fin and/or coil damage.
The force of the water or jet of air may bend the edges of the fins and
increase the air pressure drop, resulting in a reduction of performance
or irritating unit shut-off.
II.10.1.5 Cleaning fans
Check the fan grids making sure they are not obstructed by any objects
and/or filth. The latter, besides drastically reducing the overall
performance of the unit, in some cases causes the fans to break.
