How do I get an OceanAire unit for free?

Haha. Made you look.


Do the motors need lubrication?

The motors on all OceanAire units have permanently lubricated bearings. No oiling is necessary.

Clean Unit Filters


A clogged filter will cause the unit to operate at greatly reduced efficiencies. We recommend that the filter be inspected on a regular bases every six weeks or more often depending on the environment. The evaporator filter is located behind the return air grille and can be easily removed and cleaned. The condenser filter is located in the
lower backside of the unit. Remove by loosening one screw holding retaining clip and pull out. The filters must be washed periodically as needed by placing them in a dishwasher or soaking them in a solution of warm water and detergent for 10 minutes. Then rinsing them clean with hot water and shaking excess moisture from filter.

Clean Condensate Pump


Condensate pumps come standard on all Size 60 models, and may be installed as options on size 12, 18, 24 and 36 models. When servicing pump follow these steps;

  1. Make certain that the unit is disconnected from the power source before attempting to service or remove any component.
  2. Be sure the floats move freely. Clean as necessary.
  3. Remove the volute and check for obstructions. Clean as needed.
  4. Clean the tank with warm water and mild soap when mineral deposits are visible.
  5. Check the inlet and outlet piping. Clean as necessary. Be sure there are no kinks in the lines that would inhibit flow.

What do the blinking lights on my Phase Monitor mean?

GREEN-BLINKING – Start delay.  120 seconds.

GREEN-SOLID – Proper operation.

RED/GREEN-BLINKING – Signals reverse phase rotation. Switch any two of the power leads for the unit, NOT THE MONITOR LEADS, and re-start.

RED-BLINKING – Signals improper voltage and/or phase loss. Correct the power problem, then re-start the unit.


In the event of a power interruption, the unit will re-set to a start-up condition. The Phase Monitor will not allow the unit to start until power is corrected.
