Totaline® environmentally sound 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 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

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.
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 wa-
ter using downward rinsing motion of water spray nozzle.
Protect fins from damage from the spray nozzle.
CONDENSATE DRAIN — Check and clean each year at
start of cooling season. In winter, keep drains and traps dry.
FILTERS — Clean or replace at start of each heating and cool-
ing season, or more often if operating conditions require. Refer
to Installation Instructions for type and size.
NOTE: The unit requires industrial grade throwaway filters
capable of withstanding face velocities up to 625 fpm.
OUTDOOR-AIR INLET SCREENS — Clean screens with
steam or hot water and a mild detergent. Do not use disposable
filters in place of screens.
Lubrication
FAN SHAFT BEARINGS — Lubricate bearings at least ev-
ery 6 months with suitable bearing grease. Do not over grease.
Typical lubricants are given below:
*Preferred lubricant because it contains rust and oxidation inhibitors.
CONDENSER AND EVAPORATOR-FAN MOTOR BEAR-
INGS — The condenser and evaporator-fan motors have perma-
nently sealed bearings, so no field lubrication is necessary.
Evaporator Fan Performance Adjustment
(Fig. 36) —
Fan motor pulleys are designed for speed
shown in Physical Data table in unit Installation Instructions
(factory speed setting).
To change fan speeds, change pulleys.
To align fan and motor pulleys:
1. Shut off unit power supply.
2. Loosen fan shaft pulley bushing.
3. Slide fan pulley along fan shaft.
4. Make angular alignment by loosening motor from
mounting plate.
5. Retighten pulley.
6. Return power to the unit.
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 sound coil cleaner as described above.
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.
