(1) Use of antifreeze protection is required if the leaving temperature is below 3.3°C
(61XWHLZE range).
(2) For lower condenser temperatures a water flow control valve must be used at
the condenser (two or three-way valve). Please refer to option 152 to ensure
the correct condensing temperature.

Minimum chilled water flow
The minimum chilled water flow is shown in the table in chapter 7.6.
If the system flow is less than the minimum unit flow rate, the
evaporator flow can be recirculated, as shown in the diagram.

Maximum chilled water flow
The maximum chilled water flow is limited by the permitted
pressure drop in the evaporator. It is provided in the table in chapter
7.6.
Bypass the evaporator as shown in the diagram to obtain a lower
evaporator flow rate.
