10.3 Condenser Coil Cleaning
!
WARNING!
•
Excessive exposure to acidic cleaning compounds by frequency,
duration, or concentration will reduce the life of the condenser with
no commensurate benefit. Excessive cleaning will void the
warranty. Therefore, a factory-approved dealer should carefully
document the amps, pressures, temperatures, and water flow rates
that justify the coil cleaning before cleaning the coil.
•
Do not use muriatic acid (hydrochloric acid), bleach, or bromine. Do
not increase the flow rate, such as by valving off some condensers to
force more water through the others.
•
Chlorine can be very corrosive when used improperly. Dometic cau-
tions very strongly that if chlorine is chosen as the marine growth
control agent, then the user must fully understand and accept the risk
to equipment and dangers of handling corrosive chemicals. If used
excessively or improperly, damage could occur to the equipment
that is no fault of the equipment design.

NOTE
For the purpose of protecting the environment, dispose of any contam-
inated solutions in accordance with federal, state and/or local regula-
tions.
Coil cleaning is not a routine maintenance item and should not be done unless these
symptoms are present: Over a period of weeks or months, dirty coils will gradually
cause the head pressure and amperage to rise, while the capacity decreases.
➤ Turn off the system at the circuit breaker on the ship's panel.
➤ Disconnect the inlet and outlet connections of the condenser coil.
!
WARNING!
Dometic does not warrant the efficacy of any third-party cleaners.
Do not use muriatic acid (hydrochloric acid), bleach, or bromine. These
chemicals accelerate corrosion and can cause coil failure. Do not
exceed the recommended concentration or duration.
➤ Use chemical resistant hoses (MAS white PVC 5/8"/16 mm I.D., etc.) to connect
the inlet of the condenser coil to the outlet of a chemical resistant, submersible
pump (MAS P-500 pump, etc.) and let the hose connected to the coil outlet flow
freely into the container.
Use a large container as possible to hold the solution (19 – 95 l).
