• Water Rinse with Low Velocity Spray Nozzle

Environmentally Sound

Coil Cleaner Application

Instructions

• Although Environmentally Sound Coil Cleaner is harm-

less to humans, animals, and marine life, proper eye pro-

tection such as safety glasses is recommended during

mixing and application.

• Remove all surface loaded fibers and dirt with a vacuum

cleaner as described above.

• Thoroughly wet finned surfaces with clean water and a

low velocity garden hose being careful not to bend fins.

• Mix Environmentally Sound Coil Cleaner in a 2

gallon

garden sprayer according to the instructions included

with the Enzyme Cleaner. The optimum solution tem-

perature is 100 F.

NOTE: DO NOT USE

water in excess of 130 F as the enzy-

matic activity will be destroyed.

• Environmentally Sound Coil Cleaner solution to all coil

surfaces including finned area, tube sheets and coil

headers.

• 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 poten-

tial for fin damage.

• Ensure cleaner thoroughly penetrates deep into finned

areas.

• Interior and exterior finned areas must be thoroughly

cleaned.

• Finned surfaces should remain wet with cleaning solu-

tion for 10 minutes.

• Ensure surfaces are not allowed to dry before rinsing.

Reapply cleaner as needed to ensure 10-minute satura-

tion is achieved.

• 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 —

Each fan is supported by a formed

wire mount bolted to fan deck and covered with a wire guard.

The exposed end of fan motor shaft is protected from weather

by grease. If fan motor must be removed for service or replace-

ment, be sure to regrease fan shaft and reinstall fan guard. For

proper performance, fan should be positioned as in Fig. 32A

and 32B (standard and low-noise applications). Tighten set-

screws to 15 ± 1 ft-lb (20 ± 1.3 N-m).

If the unit is equipped with the high-static fan option, the fan

must be set from the top of the fan deck to the plastic ring or

center of the fan to a distance of 2.13 in. ± 0.12 in.

(54 ± 3 mm). This is different from standard fans, since there is

no area available to measure from the top of the orifice ring to

the fan hub itself. See Fig. 33.

Harsh Chemical and Acid Cleaners — Harsh chemical,

household bleach or acid cleaners should not be used

clean outdoor or indoors coils of any kind. These cleaners

can be very difficult to rinse out of the coil and can acceler-

ate corrosion at the fin/tube interface where dissimilar

materials are in contact. If there is dirt below the surface of

the coil, use the Environmentally Sound Coil Cleaner as

described above.

High Velocity Water or Compressed Air

— High veloc-

ity water from a pressure washer, garden hose or com-

pressed 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 nui-

sance unit shutdown may occur.

IMPORTANT: Check for proper fan rotation (clockwise

viewed from above). If necessary, switch any 2 power leads

to reverse fan rotation.
