➤ 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).
➤ Power the pump and circulate the solution through the condenser coil for
15 – 45 min, depending upon the size of the coils and the extent of the
contamination.
Visual inspection of the solution in the container should indicate when
the contamination removal has stopped.
➤ Circulate fresh water through the coil to flush any residual acid from the
system.
➤ Restart the system.
➤ Check operational parameters to ensure thorough cleaning has taken
place.
Additional cleaning may be necessary with extreme contamination.
I NOTE
For the purpose of protecting the environment, dispose of any con-
taminated acid solutions in accordance with federal, state and/or
local regulations.
10.4 Return Air Filters
➤ Check the return air filter about once a month and clean as necessary.
➤ To clean the filter,
– remove it from the return-air grille,
– rinse with water,
– air dry and
– reinstall.
➤ If your kit is supplied with a filtered return-air grille, the filter attached to
the unit’s evaporator must be removed.
Two filters are not better than one, as the reduced air flow will decrease
performance and possibly freeze the evaporator coil.
