EVAPORATOR COILS
The evaporator coil uses the traditional round-tube, plate-fin
(RTPF) technology. Tube and fin construction consists of vari
-
ous optional materials and coatings (see Appendix A). Coils are
multiple-row. On two-compressor units, the evaporator coil is a
face split design, meaning the two refrigerant circuits are inde
-
pendent in the coil. The bottom portion of the coil will always be
circuit A, with the top of the coil being circuit B.
Coil Maintenance and Cleaning Recommendation
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 ex
-
tend the life of the unit. The following maintenance and cleaning
procedures are recommended as part of the routine maintenance
activities to extend the life of the coil.
REMOVING 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 can be used. In either case, the tool should be applied
in the direction of the fins. Coil surfaces can be easily damaged.
Applying the tool across the fin edges can cause the edges to be
easily bent over, damaging the coating of a protected coil.
NOTE: Use of a water stream, such as a garden hose, against a
surface-loaded coil will drive the fibers and dirt into the coil. This
will make cleaning efforts more difficult. Surface-loaded fibers
must be completely removed prior to using a low-velocity clean
water rinse. A vacuum cleaner or a soft-bristled brush should be
used to remove surface-loaded fibers and dirt.
PERIODIC CLEAN WATER RINSE
A periodic clean-water rinse is very beneficial for coils that are
used in coastal or industrial environments. However, it is very im
-
portant that the water rinse is made with a very low-velocity water
stream to avoid damage to the fin edges. Monthly cleaning, as de
-
scribed below, is recommended.
ROUTINE CLEANING OF EVAPORATOR COIL SURFACES
Monthly cleaning with Totaline environmentally sound coil clean
-
er is essential to extend the life of the coils. This cleaner is avail
-
able from Carrier Replacement Parts Division (P/N: P902-0301
for a one-gallon (3.8L) container, and P/N: P902-0305 for a 5-gal
-
lon (18.9L) container). It is recommended that all round tube coils
be cleaned as described below. Coil cleaning should be part of the
unit’s regularly scheduled maintenance procedures to ensure a
long life for the coil. Failure to clean the coils can result in reduced
durability in the environment. When cleaning the coils, avoid use
of the following:
• coil brighteners
• acid cleaning prior to painting
• high pressure washers
• poor quality water for cleaning
Totaline environmentally sound coil cleaner is a nonflammable,
hypoallergenic, non bacterial, USDA accepted biodegradable
agent that will not harm the coil or surrounding 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.
