Routine Cleaning of NOVATION Condenser Coil

Surfaces

To clean the NOVATION condenser coil, chemicals are

NOT to be used; only water is approved as the cleaning

solution. Only clean potable water is authorized for

cleaning NOVATION condensers. Carefully remove any

foreign objects or debris attached to the coil face or

trapped within the mounting frame and brackets. Using a

high pressure water sprayer, purge any soap or industrial

cleaners from hose and/or dilution tank prior to wetting

the c oil.

Clea n condenser face by spraying the coil core stea dily

and uniformly from top to bottom, directing the spray

straight into or toward the coil face. Do not exceed 900

psig or a 45 degree angle; nozzle must be at least 12 in.

(30 cm) from the coil face. Reduce pressure and use

caution to prevent damage to a ir centers (fins). Do not

fracture the braze between air centers and refrigerant

tubes. Allow water to drain from the coil core and check

for refrigerant leaks prior to start--up.

NOTE: Please see the NOVATION Condenser Service

section for specific information on the coil.

PERSONAL INJURY HAZARD

Failure to follow this caution may result in personal

injury or equipment damage.

Chemical cle aning should NOT be used on the

aluminum NOVATION condenser. Damage to the coil

may occur. Only approved cleaning is recommended.

CAUTION

Routine Cleaning of Evaporator Coil Surfaces

Monthly cleaning with Totaline® environmentally sound

coil cleaner is essential to extend the life of coils. This

cleaner is available from Bryant Replacement parts

division as pa rt number P902--0301 for one ga llon

conta iner, and part number P902--0305 for a 5 gall on

container. It is recommended that all round tube coil

cle aner 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

S coil brighteners

S acid cleaning prior to painting

S high pressure washers

S poor quality water for cleaning

Totaline environmentally sound coil cle aner is

non--flammable, hypoallergenic, non--bacterial, and a

USDA accepted biodegradable agent that will not harm

coil or surrounding components such as electrical wiring,

painted metal surfaces, or insulation. Use of

non--rec ommended coil cleaners is strongly discouraged

since coil and unit durability could be affected.

Totaline Environmentally Sound Coi l Cleaner Application

Equipment

S 2-1/2 gallon garden sprayer

S water rinse with low velocity spray nozzle

PERSONAL INJURY HAZARD

Failure to follow this caution may result in corrosion

and damage to the unit.

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 environmentally sound coil cleaner as

described above.

CAUTION

PERSONAL INJURY HAZARD

Failure to follow this caution may result in reduced

unit performance.

High velocity water from a pressure washer, garde n

hose, or compressed air should neve r 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

Totaline Environmentally Sound Coil Cleaner applicat ion

Instructions

1. Proper eye protection such as safety glasses is re com-

mended during mixing and application.

2. Remove all surface loaded fibers and dirt with a vacu-

um cleaner as described above.

3. Thoroughly wet finned surfaces with clean water a nd

a low velocity garden hose, being careful not to bend

fins.

4. Mix Totaline environmentally sound coi l cleaner in a

2 1/2 gallon garden spryer according to the instruc-

tions included with the cleaner. The optimum solution

temperature is 100°F(38°C).

NOTE: Do NOT USE water in excess of 130°F(54°C),

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 ga rden sprayer nozzle close to finned areas and

apply cleaner with a vertical, 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 e xterior finned areas must be t horoughly

cleaned.
