WATER CIRCULATION PUMPS
3.4.1
Versions C0
Circulation pumps (flows and heads) must be selected and in-
stalled based on pressure losses of hydraulic circuits (
comp exchange ter appliance).
For the appliance pressure losses refer to Table 1.2
Design Manual.
Circulation pumps will be controlled at constant flow.
For pump sizing in the version KIT/2 C0 also consider the
alternate operation case.
For electrical connections of the pumps refer to Paragraph
4.5
3.4.2
Versions C1
Water circulation pumps are supplied on the appliance.
For available water flow and residual head features refer to Table
1.2
p. 21 and Design Manual.
