Totaline Environmentally Sound Coil Cleaner Application Equipment

S Water rinse with low velocity spray nozzle
!CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in accelerated corrosion of unit parts.
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 sound coil cleaner.
!CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in reduced unit performance or unit shutdown.
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 increase airside pressure drop.
Totaline Environmentally Sound Coil Cleaner Application Instructions
1.Proper eye protection such as safety glasses is recom- mended during mixing and application.
2.Remove all surface loaded fibers and dirt with a vacu- um
cleaner as described above.
