Avoid the use of:
Totaline environmentally balanced coil cleaner is non-flamma- ble, hypoallergenic, nonbacterial, and a USDA accepted biode- gradable agent that will not harm the coil or surrounding com- ponents such as electrical wiring, painted metal surfaces, or in- sulation. Use of non-recommended coil cleaners is strongly discouraged since coil and unit durability could be affected.
Totaline Environmentally Balanced Coil Cleaner Application Equipment
Harsh chemicals, household bleach or acid or basic cleaners should not be used to clean outdoor or indoor coils of any kind. These cleaners can be very difficult to rinse out of the coil and can accelerate corrosion at the fin/tube interface where dissimilar materials are in contact. If there is dirt below the surface of the coil, use the Totaline environmentally balanced coil cleaner as described above.
High velocity water from a pressure washer, garden hose, or compressed air should never be used to clean a coil. The force of the water or air jet will bend the fin edges and in- crease airside pressure drop. Reduced unit performance or nuisance unit shutdown may occur.

MICROCHANNEL HEAT EXCHANGER (MCHX) CONDENSER COIL MAINTENANCE AND CLEANING RECOMMENDATIONS
Do not apply any chemical cleaners to MCHX condenser coils. These cleaners can accelerate corrosion and damage the coil.
Routine cleaning of coil surfaces is essential to maintain proper operation of the unit. Elimination of contamination and removal of harmful residues will greatly increase the life of the coil and extend the life of the unit.
The following steps should be taken to clean MCHX condenser coils:
Excessive water pressure will fracture the braze between air centers and refrigerant tubes.
