Enviro-Coil Concentrate, Part Number H-
EC01.
Recommended Chloride Remover
CHLOR*RID DTS™ should be used to
remove soluble salts from the e-coated coil,
but the directions must be followed closely.
This product is not intended for use as a
degreaser. Any grease or oil film should first
be removed with the approved cleaning
agent.
Remove Barrier - Soluble salts adhere
themselves to the substrate. For the effective
use of this product, the product must be able
to come in contact with the salts. These salts
may be beneath any soils, grease or dirt;
therefore, these barriers must be removed
prior to application of this product. As in all
surface preparation, the best work yields the
best results.
Apply CHLOR*RID DTS - Apply directly
onto the substrate. Sufficient product must
be applied uniformly across the substrate to
thoroughly wet out surface, with no areas
missed. This may be accomplished by use of
a pump-up sprayer or conventional spray
gun. The method does not matter, as long as
the entire area to be cleaned is wetted. After
the substrate has been thoroughly wetted,
the salts will be soluble and is now only
necessary to rinse them off.
Rinse - It is highly recommended that a hose
be used, as a pressure washer will damage
the fins. The water to be used for the rinse is
recommended to be of potable quality,
though a lesser quality of water may be used
if a small amount of CHLOR*RID DTS is
added. Check with CHLOR*RID
International, Inc. for recommendations on
lesser quality rinse water.
Supply Fans
Supply Fan Lubrication
All original blower motors and bearings are
furnished with factory lubrication. Some
applications will require that bearings be re-
lubricated periodically. The schedule will
depend on the operating duty, temperature
variations or other severe atmospheric
conditions.
Bearings should be re-lubricated when at
normal operating temperatures, but not
running. Rotate the fan shaft by hand and
add only enough grease to purge the seals.
DO NOT OVERLUBRICATE.
Recommended greases are:
SHELL OIL - DOLIUM R
CHEVRON OIL - SRI No. 2
TEXACO INC. - PREMIUM R
Blower wheels must be inspected for
excessive dust build up periodically
and cleaned if required. Excessive
dust build up on blower wheels may
cause an unbalanced state; leading
to vibration and/or component failure.
Damages due to excessive dust build
up will not be covered under factory
warranty.
CAUTION
Electric shock hazard. Shut off all
electrical power to the unit to avoid
shock hazard or injury from rotating
parts.
