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 inne r coil section.
See Fig. 16.

6. Use a water hose or othe r 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 a nd 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 ga r den 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
cle aners 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 environmentall y sound coil clea ner.
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 cle aner as describe d a bove.
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 e nvironmentally sound
coil cleaner solution to all coil surfaces including
finned area, tube sheets and coil headers.
6. Hold garden sprayer noz zle close to finned are as and
apply cle aner with a vertica l, 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 m ust be thoroughly
cleaned.
9. Finned surfaces should remain wet with cleaning
solution for 10 minute s.
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 disconne cting Molex pl ug and
removing mounting screws.
3. Slide filters out of unit.
