instructions as closely as possible to avoid damaging the
coils.
Microchannel (MCHE) Coils
NOTICE
Coil Damage!
Failure to follow instructions below could result in coil
damage.
DO NOT use any detergents with microchannel
condenser coils.
Use pressurized water or air ONLY, with pressure no
greater tha
n 600psi.
For additional information regarding the proper
microchann
el coil cleaning procedure, refer to RT-
SVB83*-EN.
Due to the soft material and thin walls of the MCHE coils,
the traditional field maintenance method recommended
for Round Tube Plate Fin (RTPF) coils does not apply to
microchannel coils.
Moreover, chemical cleaners are
a risk fa
ctor to MCHE due
to the material of the coil. The manufacturer does not
recommend the use of chemical cleaners to clean
microchannel coils. Using chemical cleaners could lead to
warranty claims being further evaluated for validity and
failure analysis.
The recommended cleaning method for microchannel
coi
ls is
pressurized water or air with a non-pinpoint nozzle
and an ECU of at least 180 with pressure no greater than
600 psi. To minimize the risk of coil damage, approach the
cleaning of the coil with the pressure washer aimed
perpendicular to the face of the coil during cleaning.
Optimum clearance between the sprayer nozzle and the
microchannel coil is 1”–3”.
