3.5 Step 4 – Connection of water, vent and purge piping
For size and position of the heat exchanger water inlet and outlet connections refer to the certified dimensional
drawings supplied with the unit. See. Fig. 22 - "Standard waterboxes and nozzle arrangements" The water pipes
must not transmit any radial or axial force nor any vibration to the heat exchangers.
The water supply must be analyzed and appropriate filtering, treatment, control devices, isolation and bleed valves
and circuits built in, to prevent corrosion, fouling and deterioration of the pump fittings. Consult either a water
treatment specialist or appropriate literature on the subject.
