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 out-
er coil section 3 to 4 in. from the inner coil section.
See Fig. 10.

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.
Totaline Environmentally Sound Coil Cleaner
Application Equipment
S
2--1/2 gallon garden sprayer
S
Water rinse with low velocity spray nozzle
UNIT DAMAGE HAZARD
Failure to follow this caution may 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
!
UNIT DAMAGE HAZARD
Failure to follow this caution may result in accelerated
corrosion of unit parts.
Harsh chemicals, household bleach or 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
!
Totaline Environmentally Sound Coil Cleaner
Application Instructions
1. Proper eye protection such as safety glasses is recom-
mended during mixing and application.
2. Remove all surface loaded fibers and dirt with a vacu-
um 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 instruc-
tions included with the cleaner. The optimum solution
temperature is 100
_
F.
NOTE
: Do NOT USE water in excess of 130
_
F, 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 po-
tential 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 rinsing.
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.
2. If economizer or two--position damper is installed, re-
move economizer by disconnecting Molex plug and
removing mounting screws.
