| 4.1- Every time the unit is operated check that: 1 - With the "Control" or "Mode" switch on "0" all the check boat lights must be lit. 2 - Before turning the unit on, check that the fresh water pressure in the circuit is between 1 and 2 bars as indicated by the gauge on the unit. If the pressure drops frequently the circuit must be repaired and the leak(s) fixed as continuous topping up the pressure will dilute the antifreeze reducing the unit safety. The antifreeze solution of the Fan Coil circuit must be checked at least every 2 years. The solution to refill the circuit must be composed 80% water and 20% glycol or a good antifreeze product. 3 - Check frequently the efficiency of the seawater circuit, inspecting the seawater strainer and evaluating or even measuring the seawater flow from the outlet. We suggest keeping available a spare seal for the seawater and also one for the fresh water pump. 4 - Clean or better replace the air filters for boats on each fan coil. A dirty air filter is dramatically reducing the fan coil efficiency as it reduces the airflow. 5 - At the beginning of the summer season, check that the condensate drain from each fan coil is clean and discharges freely. Consider that in humid and hot days the condensate can reach a flow of 1 litre per hour from each fan coil. 6 - If the system is not operated for a while, we suggest turning both pump manually for few turns before running the system. |
