9. START-UP AND CONFIGRUATION
a. 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.
b. 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.
c. Setting of the wired controller. See details of the manual
concerning setting contents of the controller, including such basic
settings 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.
8.6.10 Installation of single or multiple
water pumps
9.1 Initial start-up at low outdoor ambient
temperature
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"
8.6.10.2 Installation of water pipe system
a. Single water pump
Piping does not require a one-way valve when single water pump is
installed, refer to figure as follow.
8.6.10.1 DIP switch
The choice of DIP switch see Table 8-6 in detail when single or multiple
water pumps are installed for
CSAD UiAWP 100 PS
and
CSAD UiAWP 200 PS
.
The choice of DIP switch see Table 8-7 in detail
when single or multiple
water pumps are installed for
CSAD UiAWP 300 PS.
Pay attention to the following problems:
a. If the DIP switch is inconsistent, and the error code is FP, the unit is
not allowed to operate.
b. Only the main unit has the water pump output signal when single
water pump installed, auxiliary units has no water pump output signal.
c. The water pump control signal is available for both the main unit and
auxiliary units when multiple pumps installed.

b. Multiple water pumps
Each unit is required to install a one-way valve when multiple pumps
are installed, refer to figure as follow.

8.6.10.3 Electric wiring
Only the main unit requires wiring when single water pump installed,
auxiliary units do not require wiring. All of the main unit and auxiliary
units require wiring when multiple water pumps installed.For specific
wiring, see figure 8-19 and 8-20.
