Notes:
1. Before putting into normal use for the first time, be sure to operate circulating water pumps for a certain
period of time, clean the filter and ensure that there is no debris inside the external circulating system.
2. The water outlet and the circulating water inlet must be lower than the water level switch. See details in
"Water tank structure diagram".
3. Reserve return water system is recommended for combination of more than 3 sets of units.
4. An automatic vent valve should be installed at the highest place of the water system (between the water
tank and the unit).
