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 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 tempera-
ture 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 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 rinsing.
Reapplying cleaner as needed to ensure 10-minute satura-
tion is achieved.
11. Thoroughly rinse all surfaces with low velocity clean
water using downward rinsing motion of water spray noz-
zle. Protect fins from damage from the spray nozzle.
Evaporator Coil
CLEANING THE EVAPORATOR COIL
1. Turn unit power off. Install lockout tag. Remove evapora-
tor coil access panel.
2. If economizer or two-position damper is installed, remove
economizer by disconnecting Molex plug and removing
mounting screws.
3. Slide filters out of unit.
4. Clean coil using a commercial coil cleaner or dishwasher
detergent in a pressurized spray canister. Wash both sides of
coil and flush with clean water. For best results, back-flush
toward return-air section to remove foreign material. Flush
condensate pan after completion.
5. Reinstall economizer and filters.
6. Reconnect wiring.
7. Replace access panels.
EVAPORATOR COIL METERING DEVICES
The metering devices are multiple fixed-bore devices (Acu-
trol™) swedged into the horizontal outlet tubes from the liquid
header, located at the entrance to each evaporator coil circuit
path. See Fig. 11 and 12 for units with standard metering devic-
es and Fig. 13 for units with Humidi-MiZer metering devices.
These are non-adjustable. Service requires replacing the entire
liquid header assembly.
To check for possible blockage of one or more of these meter-
ing devices, disconnect the supply fan contactor (IFC) coil,
then start the compressor and observe the frosting pattern on
the face of the evaporator coil. A frost pattern should develop
uniformly across the face of the coil starting at each horizontal
header tube. Failure to develop frost at an outlet tube can indi-
cate a plugged or a missing orifice.
