life of the coil and extend the life of the unit. The
following maintenance and cleaning procedures are
recommendedas partof the routinemaintenance activities
to extend thelife of the coil.
Remove Surface Loaded Fibers
Surface loaded fibers or dirt should be removed with a
vacuum cleaner. If a vacuum cleaner is not available,a
soft non--metallic bristle brush may be used. In either
case, the tool should be applied in the direction of the fins.
Coil surfaces can be easily damaged (fin edges can be
easily bent over and damage to the coa ting of a protected
coil) if the tool is applied acrossthe fins.
NOTE: Use of a water stream, such as a gardenhose,
against a surface loadedcoil will drive the fibers and dirt
into the coil. This will make cleaning efforts more
difficult. Surface loaded fibers must be completely
removed priorto using low velocity clean water rinse.
PeriodicClean Water Rinse
A periodic clean water rinse is very beneficial for coils
that are applied in coastal or industrial environments.
However,it is very important that the water rinse is made
with a very low velocity water stream to avoid damaging
the fin edges. Monthly cleaning as described below is
recommended.
RoutineCleaning of Coil Surfaces
Periodic cleaning with TotalineRenvironmentally sound
coil cleaner is essential to extend the life of coils. This
cleaner is available from Carrier Replacement
Components Division as part number P902--0301for a one
gallon container, and part number P902--0305 for a 5
gallon container. It is recommended that all coils,
including standard aluminum, pre--coated, copper/copper
or E--coated coils be cleaned with the Totaline
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
durabilityin the environment.
Avoiduse of:
Scoil brighteners
Sacid cleaningprior to painting
Shigh pressure washers
Spoor quality water forcleaning
Totaline environmentally sound coil cleaner is
nonflammable, hypo allergenic, non bacterial, and a
USDA accepted biodegradable agent that will not harm
the coil or surrounding components such as electric al
wiring, painted metal surfaces, or insulation. Use of
non--recommended coil cleaners is strongly discouraged
since coil and unitdurability could be affected.
One--RowCoil
Wash coil with commercial coil cleaner. It is not
necessaryto remove top panel.
Two--RowCoils
Clean coil as follows:
1. Turn off unit power, tag disconnect.
2. Remove top panel screws on condenser end of unit.
3. Remove condenser coil corner post. See Fig. 8. To
hold top panel open, place coil corner post between
top panel and centerpost. See Fig. 9.

4. Remove screws securingcoil to compressor plate and
compressoraccess panel.
5. Remove fastener holding coil sections together at re-
turn end of condenser coil. Carefully separate the out-
er coil section 3 to 4 in. from the inner coil section.
