10 Maintenance
10.1 Reversing Valve
The reversing valve must be energized periodically to keep the internal parts
moving freely.
➤ Switch the air conditioner unit into heat for a few seconds once a month.
10.2 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.
10.3 Condenser Coil Cleaning
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.
Coils can become fouled over a period of time due to marine growth or scale
build-up. This both obstructs water flow and prohibits proper heat transfer.
➤ Turn off the system at the circuit breaker on the ship’s panel.
➤ Disconnect the inlet and outlet connections of the condenser coil.
➤ Place a strainer or piece of screen over the inlet of the pump.
➤ 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.
! CAUTION!
Avoid spilling or splashing the solution.
Follow all warnings and recommendations given by the manufac-
turer of any acids or premixed solutions.
