Note:
1. When cleaning the water system, close all the gate valves as shown in position
the or valve to bypass the units to avoid foreign matters in water system entering the plate of
5 6
units, which may influence the efficiency of heat exchange and life expectancy of the plate.
2. Adopt the reversed return system in hydraulic system when two more units are combined. If the
direct return system is used, it may cause the unbalanced distribution of water flow which influences
the operation of units.
