● Bad quality water will produce more lime scale and sand: this kind of water should be filtered and
demineralized.
●The water quality should be analyzed before operating the unit: PH value, conductivity, chloride ion
concentration and sulphate ion concentration should be checked.
●Acceptable water quality shown below:
PH value Total hardness Conductivity Sulphate ion Chlorine ion Ammonia ion

● Suggested filter mesh = 40.
6.Installation of optional accessories
6.1 Selection of the water pump
●The circulation pump is required for the system to operate, there is a terminal connection for the pump
(single phase)
NOTE
For single-phase pumps, please check the wiring diagram.
●Head of circulation pump = height difference between water level and main unit + total pipeline resistance
(determined by the hydraulic calculation) + pressure loss of main unit (see nameplate on heat pump).
NOTE
Multiple units installed in parallel place more demand on the water pump requirement.
6.2 Water pipe selection
●The selection of the water pipe should be based on the actual system specifications
●The flow switch can be installed horizontally or vertically. If installed vertically, th e direction of the water
