Maintenance

Reversing Valves

Reverse cycle units have a reversing valve; the valve must be energized periodically to keep the internal parts moving

freely. To do this, switch the air conditioning unit into heat mode 2-3 cycles per month.

Seawater Strainer

Ensure that your pump receives adequate seawater flow by regularly cleaning the strainer basket. Periodically check the

overboard discharge for a steady stream of water. Check seawater intake speed scoop for obstructions. Make sure

hoses are not looped, kinked or crushed. Check and clean strainer as needed minimum once per month.

Condenser Coil Cleaning (Seawater Acid Flush)

1. With the system turned off at the circuit breaker on the ship's panel, disconnect the inlet and outlet connections

of the condenser coil.

2. Use chemical resistant hoses (PVC 5/8" I.D., etc.) to connect the inlet of the condenser coil to the outlet of a

chemical resistant, submersible pump and let the hose connected to the Coil outlet flow freely into the container

mentioned below.

3. Place a strainer or piece of screen over the inlet of the pump and submerse the pump into a container filled with

a 5% solution of muriatic or hydrochloric acid and fresh water or use a premixed over-the-counter solution. Use a

large container as possible to hold the solution (5-25 gallons). CAUTION: avoid spilling or splashing the solution.

Remember to wear all necessary protective gear, i.e. approved safety goggles and chemical resistant gloves.

Follow all warnings and recommendations given by the manufacturer of any acids or premixed solutions.

4. Power the pump and circulate the solution through the condenser coil for 15-45 minutes 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 has been removed.

5. Circulate fresh water through the coil to flush any residual acid from the system.

6. Restart the system and check operational parameters to ensure thorough cleaning has taken place. Additional

cleaning may be necessary with extreme contamination.

7. Minimum once per year or as needed.

For the purpose of protecting the environment, dispose of any contaminated acid solutions in

accordance with federal, state and/or local regulations.

Return Air Filters

Check the return air filter about once a month and clean as necessary. To clean the filter, remove it from the unit, rinse

with water, air dry and reinstall. (Do not used compressed air)
