Warranty claims related to cleaning damage, especially for
incorrect pressure washing operation, or corrosion resulting
from applying non-recommended cleaners, will NOT be
honored.
STEP 3: Remove Surface Debris
Depending on the installation and fin geometry,
MicroChannel heat ex
changers could possibly retain more
water compared to traditional tube & fin coils. It is advised
to blow off or vacuum out the residual water from the coil to
speed up drying and prevent pooling. Daikin recommends
a quarterly cleaning of the coils, as the minimum. The
cleaning frequency should be increased dependin
g on the
level of dirt/dust accumulation and the environment (e.g.,
coastal areas with chlorides and salts) or industrial areas
with aggressive substances.
WARNING
Field applied coatings are not recommended for brazed alu-
minum MicroChannel heat exchangers. MicroChannel heat
exchangers must NOT be coated using any other coating,
Coating of a coil using a supplier or coating process is not
approved and is not covered by the warranty. It may also
reduce the lifetime and/or the performance of the Micro-
Channel heat exchanger.
