NOTE: Use of a water stream, such as a garden hose, against a surface
prior to using low velocity clean water rinse.
Periodic Clean Water Rinse
A monthly clean water rinse is recommended for coils that are applied in
coastal or industrial environments to help to remove chlorides, dirt and debris.
It is very important when rinsing, to water temperature is less than 54° C and
temperature (not to exceed 54° C) will reduce surface tension, increasing the
ability to remove chlorides and dirt.

1. 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.
2. Apply CHLOR*RID DTS - Apply CHLOR*RID DTS directly onto
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.
3. Rinse - It is highly recommended that a hose be used, as a pressure
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.
CAUTION:
Harsh Chemical and Acid Cleaners
Harsh chemicals, household bleach or acid cleaners should not be used to
recommended coil cleaners as described above.
CAUTION:
High Velocity Water or Compressed Air
High velocity water from a pressure washer or compressed air should only
drop. Reduced unit performance or nuisance unit shutdowns may occur.
Cleaning fans
DANGER!
Pay attention to the fans. Do not remove the protective grids for any reason
whatsoever!
Check the fan grilles making sure they are not obstructed by any objects
of the unit, in some cases causes the fans to break.
Checking compressor oil level
IMPORTANT!
Do not use the unit is the oil level in the compressor is low.
The lubricating oil level in the compressor can be checked by means of
the sight-glass. The oil level in the sight-glass can be inspected while
the compressor is running. At times a small amount of oil could migrate
can therefore be considered normal.
in any event, the oil level must always be visible through the sight-
glass. The presence of foam when the unit starts is normal. A prolonged
and excessive presence of foam during operation, on the other hand,
means that the refrigerant has not dissolved in the oil.
