Microchannel (MCHE) Coil Cleaning for Next Gen Precedent

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 than 600psi.
For additional information regarding the proper
microchannel coil cleaning procedure, refer to RTSVB83*-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
factor 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
condenser coils is pressurized water or air with a nonpinpoint 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.

please refer to bulletin RT-SVB83*-EN.
