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. An elevated water temperature (not
to exceed 130ºF) will reduce surface tension, increasing the
ability to remove chlorides and dirt. Pressure washer PSI must
not exceed 900 psig and the nozzel should remain at least 1
foot from the coil to avoid damaging n edges.
Routine Quarterly Cleaning of ElectroFin
Coated Coil Surfaces
Quarterly cleaning is essential to extend the life of an
ElectroFin Coated Coil and is required to maintain warranty
coverage. Coil cleaning shall be part of the unit’s regularly
scheduled maintenance procedures. Failure to clean an
ElectroFin Coated Coil will void the warranty and may result in
reduced efciency and durability in the environment.
For routine quarterly cleaning, rst clean the coil with an
approved coil cleaner (see approved products list in Table 87).
After cleaning the coils with the approved cleaning agent, use
the approved chloride remover to remove soluble salts and
revitalize the unit.
Recommended Coil Cleaner
The following cleaning agent, assuming it is used in
accordance with the manufacturer’s directions on the container
for proper mixing and cleaning, has been approved for use on
ElectroFin Coated Coils to remove mold, mildew, dust, soot,
greasy residue, lint and other particulate:

Chlor*Rid DTS
CHLOR*RID DTS™ should be used to remove soluble salts
from the ElectroFin Coated Coil, but the directions must be
followed closely. This product is not intended for use as a
degreaser. Any grease or oil lm should rst be removed with
the approved cleaning agent.
1. Remove Barrier - Soluble salts adhere themselves
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 onto the substrate. Sufcient product must be
applied uniformly across the substrate to thoroughly
wet out surface with no areas missed. This may
be accomplished by use of a pump-up sprayer or
conventional spray gun. The method does not matter, as
long as the entire area to be cleaned is wetted. 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 highly recommended that a hose be used
as a pressure washer will damage the ns. The water to
be used for the rinse is recommended to be of potable
quality, though a lesser quality of water may be used if a
small amount of CHLOR*RID DTS is added. Check with
CHLOR*RID International, Inc. for recommendations on
lesser quality rinse water.
Harsh Chemical and Acid Cleaners
Harsh chemicals, household bleach or acid cleaners should
not be used to clean outdoor or indoor ElectroFin Coated
Coils. These cleaners can be very difcult to rinse out of the
coil and can accelerate corrosion and attack the ElectroFin
coating. If there is dirt below the surface of the coil, use the
recommended coil cleaners as described above.
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 n and/
or coil damages. The force of the water or air jet may bend the
n edges and increase airside pressure drop. Reduced unit
performance or nuisance unit shutdowns may occur.
Electrical Terminals
DANGER
Electric shock hazard. Turn off all power before continuing
with following service.
High Ambient Control Panel
This option consists of an exhaust fan with rain hood, two inlet
screens with lters, necessary controls and wiring to allow
operation to 125°F (52°C). The components can be factory or
eld installed as a kit.
• It must be supplied on units operating at ambient
temperatures of 105°F (40.6°C) and above.
• It is automatically included on units with fan VFD (low
ambient option).
• Check inlet lters periodically and clean as required.
Verify that the fan is operational.
