Evaporator Coils - Bryant 580J D17 Service And Maintenance Instructions

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
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.
Two−Row Coils
Clean coil as follows:
1. Turn off unit power and tag the disconnect.
2. Remove the top panel screws on the condenser end of
the unit.
3. Remove the condenser coil corner post. See Fig. 12.
To hold the top panel open, place the coil corner post
between the top panel and center post. See Fig. 13.

4. Remove the screws securing the coil to the compres-
sor plate and compressor access panel.
5. Remove the fastener holding the coil sections togeth-
er at the return end of the condenser coil. Carefully
separate the outer coil section 3 to 4 in. from the in-
ner coil section. See Fig. 14.

6. Use a water hose or other suitable equipment to flush
down between the 2 coil sections to remove dirt and
debris. Clean the outer surfaces with a stiff brush in
the normal manner.
7. Secure the inner and outer coil rows together with a
field−supplied fastener.
8. Reposition the outer coil section and remove the coil
corner post from between the top panel and center
post. Install the coil corner post and replace all
screws.

EVAPORATOR COILS

The evaporator coil uses the traditional round- tube,
plate-fin (RTPF) technology. Tube and fin construction
consists of various optional materials and coatings (see
APPENDIX I. MODEL NUMBER NOMENCLATURE).
Coils are multiple-row. On two-compressor units, the
evaporator coil is a face split design, meaning the two
refrigerant circuits are independent in the coil. The bottom
portion of the coil will always be circuit A, with the top of
the coil being circuit B.
