Cleaning Standard and Environment Guard microchannel coils
Standard and Environment Guard microchannel coils must be cleaned following this procedure at
least once every quarter or every 3 months to ensure that the integrity of the coils and the warranty
of the coils are maintained. In environments where coils become heavily fouled or where there are
high levels of pollution or corrosive elements, a monthly frequency of cleaning is recommended.
Refer to the Microchannel Heat Exchanger Application Guide, Form 150-12-AD1, for further details on
the classification of polluted and corrosive environments.
CAUTION
Proper care must be taken to ensure that cleaning agents and water are not sprayed directly onto
electrical components and wiring in the V-panels and the chiller.
Note: Standard and Environment Guard coils are gray-silver in color.
1. Use a vacuum cleaner with a soft brush attachment to remove surface debris such as dirt,
leaves, insects, or fibers. When brushing debris off the face of the coil, you can also use a
soft bristle brush. Do not use a wire brush. Do not scrape the coil with the vacuum nozzle, air
nozzle, or any other hard tool.
2. Rinse the coil with potable tap water. Use a gentle spray from a spray nozzle with a plastic
end. Do not contact the coil with the hose nozzle. Rinse the coil by running water through
every passage in the heat exchanger surface until it is clean.
3. Apply a coil cleaning solution approved by Johnson Controls, such as RectorSeal brand
GulfClean
™
coil cleaner, or equivalent, on the microchannel coils. Coil cleaning solution is
available from Johnson Controls Aftermarket Parts Centers in all global regions.
a. Mix the correct amount of cleaner solution and water in accordance with the
manufacturer’s directions on the container.
b. Use a hand-held pump sprayer to apply the mixed cleaner solution on the coils.
c. Make sure to wet the entire surface of the coils with the solution.
d. Leave the cleaning solution on each of the coils for approximately 10 min.
4. Repeat the water rinse procedure in Step 2 to remove the cleaning solution.
5. It is important to remove any excess water trapped in the coils immediately after the final
water rinse.
a. To fully dry the coils, run the condenser fans on the chiller after the final water rinse.
b. To remove any excess water, blow air through the coils with a hand-held blower or
vacuum.
