9. STRAT-UP AND CONFIGRUATION
9.3.1 After the water system pipeline is flushed several times,
please make sure that the purity of water meets the requirements;
the system is re-filled with water and drained, and the pump is
started up, then make sure that water flow and the pressure at the
outlet meet the requirements.
9.3.2 The unit is connected to the main power 12 hours before
being started up, to supply power to the heating belt and pre-heat
the compressor. Inadequate pre-heating may cause damages to
the compressor.
9.3.3 Setting of the wired controller. See details of the manual
concerning setting contents of the controller, including such basic
Zsettings as refrigerating and heating mode, manual adjustment
and automatic adjustment mode and pump mode. Under normal
circumstances, the parameters are set around standard operating
conditions for trial run, and extreme working conditions should be
prevented as much as possible.
9.3.4 Carefully adjust the target flow controller on the water
system or the inlet stop valve of the unit, to make the water flow of
the system be 90% of the water flow specified in troubleshooting
table.
9.4 ON/OFF
Turn on the unit
Press “MENU” key to set the intended
mode.
Power up to module unit and initially deliver

9.1 Initial start-up at low outdoor ambient
temperatures
9.2 Points for attention prior to trial run
During initial start-up and when water temperature is low, it is important
that the water is heated gradually. Failure to do so may result in
concrete floors cracking due to rapid temperature change. Please
contact the responsible cast concrete building contractor for further
details.
To do so, the lowest water flow set temperature can be decreased to
a value between 25°C and 35°C by adjusting the FOR SERVICEMAN.
Refer to "FOR SERVICEMAN/special function/preheating for floor"
