Checklist The table below contains the water piping checklist.
Water volume, flow
and pressure
The table below shows the operation range of water volume and water flow for proper operation of the
unit.
Step Check whether...
1 A filter is installed in front (less than 1 meter) of the water inlet of the plate-heat exchanger.
The plate-heat exchangers are sensitive to dirt and small particles
(Maximum filter mesh of 1mm).
2 The water volume is within the limits.
3 There is adequate water flow.
4 The water quality meets the standards.
5 The water piping is properly insulated.
6 Measurement points for temperature and pressure are available on the water circuit.
7 The flow switch and pump are properly working.
8 Air purge points are installed on the high parts of the water piping.
9 Drain taps are installed at the low points of the water piping.
10 Other parts of the water circuit are properly mounted and installed (e.g. buffer tank, expan-
sion tank...).
11 Vibration compensators are mounted at the water connections if the unit is positioned on
anti-vibration pads.
