Note: Do not exceed the maximum operating temperature.
(1) For entering water temperatures below 7.5°C at start-up, contact Carrier.
(2) For low-temperature applications, where the leaving water temperature is below
5°C, a frost protection solution must be used.
(3) For transport and storage of the 30RQS/30RQSY units the minimum and
maximum allowable temperatures are -20°C and +48°C. It is recommended that
these temperatures are used for transport by container.
(4) Denes the frost-free temperature of the hydraulic components for use without
glycol.

(1) Maximum ow rate at a pressure drop of 100 kPa in the plate heat exchanger
(unit without hydraulic module).
(2) Maximum ow rate at an available pressure of 20 kPa (unit with low-pressure
hydraulic module) or 50 kPa (high-pressure module).
(3) Maximum ow rate with single pump is 2 to 4% higher, depending on the size
