1. Chemicals to aid in cleaning WILL VOID WARRANTY and are NOT RECOMMENDED.
2. In some instances, it may take a combination of two methods to result in a clean coil. Such as, first wiping
the coil to clean the surface and then using a vacuum, water or compressed air to clean down in the fins. This
will depend on the type of debris that needs to be cleaned from the coil.
3. Do not allow the coil to come into contact with any hard vacuum nozzle, air nozzle, or any other tool. This will
damage the tubes of the coil.
4. The use of cleaning agents or detergents is strongly discouraged due to the possibility of degradation of the
construction. If using a power washer, the nozzle pressure should not exceed 600 psi (41 bar). For the best
results, spray the coil perpendicular to the face of the coil. The spray nozzle should be kept between 1 inch
and 3 inches (25 to 75 millimetres) from the coil surface.
5. If necessary to use a chemical cleaner or detergent use a cleaner that does not contain any hydrofluoric acids
and is between 7 and 8 on the pH scale. Ensure dilution instructions provided by the detergent supplier are
followed. In case of doubt about the compatibility of the detergent with the type of materials listed above,
always ask the supplier for a written confirmation of the compatibility. Should a chemical cleaner be
required, it is MANDATORY that all components are thoroughly rinsed with water even if the instructions of
the cleaner specify that it is a “no rinse” cleaner.

6. The repeated transportation of meat and fish waste can cause extensive corrosion to the evaporator coils
and evaporator section tubing over time due to ammonia formation and can reduce the lifespan of the coils.
Appropriate additional measures should be taken to protect the coils against the aggressive corrosion that
can result from transportation of such products.
