Totaline Environmentally Sound Coil Cleaner Application
Equipment
• 2
1
/
gallon garden sprayer
2
• water rinse with low velocity spray nozzle.
CAUTION
Harsh chemicals, household bleach or acid or basic clean-
ers 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 inter-
face where dissimilar materials are in contact. If there is
dirt below the surface of the coil, use the Totaline
ronmentally sound coil cleaner as described on page 53.
CAUTION
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. Reduced unit performance
or nuisance unit shutdown may occur.
Totaline Environmentally Sound Coil Cleaner Application
Instructions
1. Remove any foreign objects or debris attached to the coil
face or trapped within the mounting frame or brackets.
2. Put on personal protective equipment including safety
glasses and/or face shield, waterproof clothing and
gloves. It is recommended to use full coverage clothing.
3. Remove all surface loaded fibers and dirt with a vacuum
cleaner as described above.
4. Thoroughly wet finned surfaces with clean water and a
low velocity garden hose, being careful not to bend fins.
5. Mix Totaline environmentally sound coil cleaner in a
2

/
gallon garden sprayer according to the instructions

included with the cleaner. The optimum solution temper-
ature is 100 F.
NOTE: Do NOT USE water in excess of 130 F, as the enzy-
matic activity will be destroyed.
6. Thoroughly apply Totaline environmentally sound coil
cleaner solution to all coil surfaces including finned area,
tube sheets and coil headers.
7. 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.
8. Ensure cleaner thoroughly penetrates deep into finned
areas.

9. Interior and exterior finned areas must be thoroughly
cleaned.
10. Finned surfaces should remain wet with cleaning solution
for 10 minutes.
11. Ensure surfaces are not allowed to dry before rinsing.
Reapplying cleaner as needed to ensure 10-minute satura-
tion is achieved.
12. 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.
Microchannel Heat Exchanger (MCHX) Con-
denser Coil Maintenance and Cleaning Rec-
ommendations —
essential to maintain proper operation of the unit. Elimination
of contamination and removal of harmful residues will greatly
increase the life of the coil and extend the life of the unit. The
following steps should be taken to clean MCHX condenser
coils:
Do not apply any chemical cleaners to MCHX condenser
coils. These cleaners can accelerate corrosion and damage
the coil.
1. Remove any foreign objects or debris attached to the coil
face or trapped within the mounting frame and brackets.
2. Put on personal protective equipment including safety
glasses and/or face shield, waterproof clothing and
gloves. It is recommended to use full coverage clothing.
3. Start high pressure water sprayer and purge any soap or
industrial cleaners from sprayer before cleaning condens-
er coils. Only clean potable water is authorized for clean-
ing condenser coils.
4. Clean condenser face by spraying the coil steady and uni-
formly from top to bottom while directing the spray
straight toward the coil. Do not exceed 900 psig or
30 degree angle. The nozzle must be at least 12 in. from
the coil face. Reduce pressure and use caution to prevent
damage to air centers.
Excessive water pressure will fracture the braze between
air centers and refrigerant tubes.
Condenser Fans —
fan deck supports each fan and motor assembly. A shroud and a
wire guard provide protection from the rotating fan. The ex-
posed end of fan motor shaft is protected from weather by
