II.11.1.4 Micro-channel coil with E-coating treatment
(MCHXE accessory)
Procedures for Cleaning ElectroFin® Coated Coils
The following cleaning procedures are recommended as part of the
routine maintenance activities for ElectroFin® Coated Coils.
Documented routine cleaning of ElectroFin® coated coils is required to
maintain warranty coverage.
IMPORTANT!
Before cleaning the unit, shut off and lock the main
power supply switch of the unit and open all access
panels.
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 it is not possible to counter-wash the fan coil opposite the one where
air enters, eliminate fibres and filth accumulated on the surface using 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 cleaning equipment or the fan between the fins may easily
damage surfaces of the fan coil (bending the fin edges).
NOTE: using a water jet, for example using a garden hose, against a
floor fan coil pushes fibres and filth inside the equipment, making
cleaning operations 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
Routine Quarterly Cleaning is fundamental to extend the life of the
ElectroFin® Coated Fan Coil, as well as being necessary for the
warranty to be valid. Fan coil cleaning must be part of routine
maintenance procedures planned for the unit. Not cleaning the
ElectroFin® Coated Coil Surfaces cancels the warranty and reduces
efficiency and duration in the environment. As far as routine quarterly
cleaning, start treating the fan coil using the specific approved detergent
shown here below (see the list of approved products in the
recommended Detergents section for fan coils). After cleaning the fan
coils using the specific detergent, use the approved Chloride Remover
(in the recommended Chloride Remover agents section) to remove
soluble salts and recondition the unit.
Recommended Coil Cleaner
The detergent shown here below, as long as it is used in conformity
with the manufacturer instructions shown on the container, related to
correct mixing and cleaning, has been approved for use on fan coils
with Electro Fin® e-coating to remove dirt, mould, dust, soot, grease
residue, lint and other materials:

CHLOR*RID DTS™ must be used to eliminate soluble salts from the
fan coil with ElectroFin® coating carefully following supplied
instructions. 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
Harsh Chemical agents, domestic use bleach or acid cleaners must
never be used to clean fan coils with external or internal ElectroFin®
coating, since they are very difficult to eliminate when rinsing and may
accelerate the corrosion process, attacking the ElectroFin® coating.
With filth present under the surface of the fan coil, use recommended
detergents, as described previously.
ATTENTION:
High Velocity Water or Compressed Air
High velocity water from a pressure washer or compressed air should
only be used at a very low pressure to prevent fin and/or coil damages.
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.11.1.5 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.

DANGER!
Pay attention to the fans. Do not remove the
protective grids for any reason whatsoever!
