9.2 Initial start-up at low outdoor ambient temperature 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 SPECIAL FUNCTION. 9.
9.4 Setting the pump The pump is contolled via a digital low-voltage pulse-width modulation signal which means that the speed of rotation depends on the input signal.The speed changes as a function of the input profile. The relationships between the head and the water flow rated,the PMW Return and the water flow rated are shown in the graph below.
Failure diagnosis at first installation If nothing is displayed on the user interface, it is necessary to check for any of the following abnormalities before diagnosing possible error codes. -Disconnection or wiring error (between power supply and unit and between unit and user interface). -The fuse on the PCB may be broken. If the user interface shows "E8" or "E0" as an error code, there is a possibility that there is air in the system, or the water level in the system is less than the required minimum.

14 INFORMATION SERVICING 1) Checks to the area Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minmised. For repair to the refrigerating system, the following precautions shall be complied with prior to conducting work on the system. 2) Work procedure Works shall be undertaken under a controlled procedure so as to minimise the risk of a flammable gas or vapour being present while the work is being performed.
10) Repairs to sealed components a) During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc. If it is absolutely necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation.
Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to minimize the amount of refrigerant contained in them. Cylinders shall be kept upright. Ensure that the refrigeration system is earthed prior to charging the system with refrigerant. Label the system when charging is complete(if not already). Extreme care shall be taken not to overfill the refrigeration system.
