Routine Cleaning Of Rtpf Coil Surfaces; Condenser Fans - Carrier AquaForce 30XV140 Controls, Start-Up, Operation, Service And Troubleshooting Instructions

the water rinse is made with very low velocity water stream to
avoid damaging the fin edges. Monthly cleaning as described
below is recommended.
ROUTINE CLEANING OF RTPF COIL SURFACE —
Routine cleaning with Totaline
cleaner is essential to extend the life of coils. This cleaner is
available from Carrier Replacement Parts division as part num-
ber P902-0301 for a one gallon container, and part number
P902-0305 for a five gallon container. It is recommended that
all coils, including the standard copper tube aluminum fin, pre-
coated fin, copper fin, or e-coated coils be cleaned with the
Totaline environmentally balanced coil cleaner as described
below. Coil cleaning should be part of the unit's regularly
scheduled maintenance procedures to ensure long life of the
coil. Failure to clean the coils may result in reduced durability
in the environment. Avoid the use of:
• coil brighteners
• acid cleaning prior to painting
• high pressure washers
• poor quality water for cleaning
Totaline environmentally balanced coil cleaner is non-flam-
mable, hypoallergenic, nonbacterial, and a USDA accepted
biodegradable agent that will not harm the coil or surrounding
components such as electrical wiring, painted metal surfaces,
or insulation. Use of non-recommended coil cleaners is strong-
ly discouraged since coil and unit durability could be affected.
Totaline Environmentally Balanced Coil Cleaner Applica-
tion 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 environ-
mentally balanced coil cleaner as described above.
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 Balanced Coil Cleaner Applica-
tion 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 balanced coil cleaner in
a 2 1 / gallon garden sprayer according to the instruc-
2
tions included with the cleaner. The optimum solution
temperature is 100 F (37.8 C).
NOTE: Do NOT USE water in excess of 130 F (54.4 C), as the
enzymatic activity will be destroyed.
5. Thoroughly apply Totaline environmentally balanced 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 ap-
ply 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. Re-
apply 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.
Condenser Fans —
the coil caps supports each fan and motor assembly. A shroud
and a wire grille provide protection from the rotating fan. See
Fig. 59. To remove the fan a special puller (RCD part no.
30RB680082) can be used. The fan utilizes a set screw and
does not require the use of retaining compound in the key-
way. The fan can be removed without the puller, but its use
eases disassembly. The exposed end of the fan motor shaft is
protected from weather by grease. If fan motor must be re-
moved for service or replacement, re-grease the fan shaft.
The fan needs to be positioned fully down against the step on
the motor shaft. Apply blue thread locker (Loctite 243) to the
threads of both the axial bolt and the set screw. Install the
thick washer and M8 axial bolt; do not fully tighten. Install
set screw and tighten to 16 ± 2 ft-lbs (21.7 ± 2.7 Nm). Torque
the axial bolt to 24 ± 2 ft-lbs (32.5 ± 2.7 Nm). Reinstall
shroud and wire grille.
