Routine Cleaning of NOVATION Condenser Coil
Surfaces
DO NOT clean the NOVATION condenser coil with
chemicals. ONLY water is approved as cleaning solution.
Only clean potable water is authorized for cleaning
NOVATION condensers. Remove any foreign objects or
debris attached to the coil face or trapped within the
mounting frame and brackets. Use a high pressure water
sprayer to purge any soap or industrial cleaners from hose
and/or dilution tank before wetting the coil.
WARNING
!
EXPLOSION HAZARD
Failure to follow this warning could
result in death, serious personal injury,
and/or property damage.
Never use air or gases containing
oxygen for leak testing or operating
refrigerant compressors. Pressurized
mixtures of air or gases containing
oxygen can lead to an explosion.

EQUIPMENT DAMAGE HAZARD
Failure to follow this caution can result in equipment
damage.
DO NOT use Totaline® environmentally sound coil
cleaner on the aluminum NOVATION condenser.
Damage to the coil can occur. Only clean potable
water is authorized for cleaning.

UNIT OPERATION AND SAFETY HAZARD
Failure to follow this warning could cause personal
injury, death.
Using a high pressure washer (900 psig − 6205 kPa)
to clean coils can cause severe injury or death if
spray is aimed at service personnel. Do not use a
high pressure washer to clean hands and do not direct
spray in direction of eyes or other tissue.
Recommended Condenser Coil Maintenance
and Cleaning
Routine cleaning of coil surfaces is 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 maintenance and cleaning procedures are
recommended as part of the routine maintenance activities
to extend the life of the coil.
Remove Surface Loaded Fibers
Surface loaded fibers or dirt should be removed with a
vacuum cleaner. If a vacuum cleaner is not available, a
soft non−metallic bristle brush may be used. In either
case, the tool should be applied in the direction of the fins.
Coil surfaces can be easily damaged (fin edges can be
easily bent over and damage to the coating of a protected
coil) if the tool is applied across the fins.
NOTE: Use of a water stream, such as a garden hose,
against a surface loaded coil will drive the fibers and dirt
into the coil. This will make cleaning efforts more
difficult. Surface loaded fibers must be completely
removed prior to using low−velocity clean water rinse.
Periodic Clean Water Rinse
A periodic clean water rinse is very beneficial for coils
C07273B
that are applied in coastal or industrial environments.
However, it is very important that the water rinse is made
with a very low−velocity water stream to avoid damaging
the fin edges. Monthly cleaning as described below is
recommended.
UNIT DAMAGE HAZARD
Failure to follow this CAUTION can result in reduced
unit performance or unit shutdown.
Use only the recommended approved cleaning
procedures for proper system performance.
