4. Remove screws securing coil to compressor plate
and compressor access panel.
5. Remove fastener holding coil sections together at re-
turn end of condenser coil. Carefully separate the
outer coil section 3 to 4 in. from the inner coil sec-
tion. See Fig. 17.

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 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. Reinstall the coil corner post and replace all
screws.
UNIT DAMAGE HAZARD
Failure to follow this caution can result in accelerated
corrosion of unit parts.
Harsh chemicals, household bleach, 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 can 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.
CAUTION
!
Totaline Environmentally Sound Coil Cleaner
Application Equipment
S
2--1/2 gallon garden sprayer
S
Water rinse with low velocity spray nozzle
Totaline Environmentally Sound Coil Cleaner
Application Instructions
1. Proper eye protection such as safety glasses is
recommended during mixing and application.
2. Remove all surface loaded fibers and dirt with a
vacuum cleaner as described above.
3. Thoroughly wet finned surfaces with clean water and
a low velocity garden hose, being careful not to bend
fins.
4. Mix Totaline environmentally sound coil cleaner in a
2--1/2 gallon garden sprayer according to the
instructions included with the cleaner. The optimum
solution temperature is 100
_
F.
NOTE : Do NOT USE water in excess of 130
_
F (54
_
C)
as the enzymatic activity will be destroyed.
5. Thoroughly apply Totaline environmentally sound
coil cleaner solution to all coil surfaces including
finned area, tube sheets and coil headers.
6. Hold garden sprayer nozzle close to finned areas and
apply cleaner with a vertical, up--and--down motion.
Avoid spraying in horizontal pattern to minimize
potential for fin damage.
7. Ensure cleaner thoroughly penetrates deep into
finned areas.
8. Interior and exterior finned areas must be thoroughly
cleaned.
9. Finned surfaces should remain wet with cleaning
solution for 10 minutes.
10. Ensure surfaces are not allowed to dry before rins-
ing. Reapplying cleaner as needed to ensure
10--minute saturation is achieved.
11. Thoroughly rinse all surfaces with low velocity
clean water using downward rinsing motion of water
spray nozzle. Protect fins from damage from the
spray nozzle.
Evaporator Coil
Cleaning the Evaporator Coil
1. Turn unit power off. Install lockout tag. Remove
evaporator coil access panel.
