CAUTION
UNIT DAMAGE HAZARD
Failure to follow this CAUTION can result in reduced
unit performance or unit shutdown.
Use only the recommended approved cleaning
procedures for proper system performance.
Routine Cleaning of Coil Surfaces
Periodic cleaning with TotalineR environmentally sound
coil cleaner is essential to extend the life of coils. This
cleaner is available from the Replacement Components
Division as p/n: P902- 0301 for one-gallon (3.8L)
container, and P902- 0305 for a 5-gallon (18.9L)
container. It is recommended that all coils, including
standard aluminum, pre−coated,
E−coated coils be cleaned
environmentally sound coil cleaner as described below.
Coil cleaning should be part of the unit's regularly
scheduled maintenance procedures to ensure long life of
the coil. Failure to clean the coils may result in reduced
durability in the environment.
Avoid use of:
S coil brighteners
S acid cleaning prior to painting
S high pressure washers
S poor quality water for cleaning
TotalineR environmentally sound coil cleaner is a non-
flammable, hypo allergenic, non bacterial, USDA accept-
ed biodegradable agent that will not harm the coil or sur-
rounding components such as electrical wiring, painted
metal surfaces, or insulation. Use of non−recommended
coil cleaners is strongly discouraged since coil and unit
durability could be affected.
