Flow Rates and Output Water Temperature
Flow rate in (ltr/min), related to output water temperature (°C) and optimised electrical energy usage (kW).
The incoming water temperature will vary during Summer and Winter. The following tables show the hot water
output temperatures attainable at various flow rates, for each of the CFEWH SERIES 1 Models available.
Maximum Rated Operating Water Pressure
The maximum operating water pressure is 10 MPa/10 bar/150 PSI.
Water Resistivity
The resistivity of the potable water must not be less than 1.25k
Ω
-cm, and should not be greater than
12.5k
Ω
-cm. If the unit is operated with water conductivities outside of this range, it will not function as specified.
IP Rating
The unit is rated as IP44. The appliance must be installed inside a dwelling or construction and should not be
exposed to splashing water, rain or any circumstance that will allow water to enter the outside cover.
Ambient Temperature
The unit is intended for internal installation and should not be installed in an environment where there is a
possibility of the ambient temperature dropping below 5°C.
Reference
IMPORTANT
Where the ambient temperatures are likely to approach freezing – ie: less than 5°C – the unit must be
drained of water to prevent frozen water damage occurring.
Failure to comply with the installation and operating instructions or improper use voids the warranty.
