The following is only to be used as a guide-line, 5.1 - Power supply and does not make Carrier in any way liable. After wire sizing has been completed, using the certified dimensional drawing, The power supply must conform to the specification on the the installer must ensure easy connection and define any chiller nameplate.
The maximum chilled water flow is shown in the table on the Full load next page. If the system flow exceeds the maximum value, it Note: can be bypassed as shown in the diagram. Evaporator ∆T = 5K These ranges are given by way of indication. Verify the operating range from the Carrier electronic catalogue. For maximum chilled water flow rate Legend Operating range, standard unit 30XAV Below 0 °C air temperature the unit must either be equipped with the evaporator freeze protection option 41A, or the water loop must be protected against freeze by using a freeze protection solution (by the installer).
6.4 - Variable flow evaporator Connection to a buffer tank Variable evaporator flow can be used as standard with 30XAV chillers. The chillers maintain a constant leaving water temperature under all flow conditions. For this to happen, the flow rate must be higher than the minimum flow given Good in the table of permissible flow rates and must not vary by more than 10% per minute.

7.7 - Operation of two units in master/slave mode 30XAV with configuration: Leaving water control (option 58) As standard, the control of a master/slave assembly is from the entering water temperature and does not require any additional sensors (standard configuration). It can also be controlled from the leaving water temperature, in this case two additional sensors must be added on the common piping.
8 - UNIT WITH HYDRONIC KIT 8.1 - Available static pressure for the system Data applicable for fresh water, 20°C - In case of use of the glycol, the maximum water flow is reduced - Glycol percentage is limited to 40% - For ambiant temperature over 40°C, maximum water flow is limited Low pressure pumps (options 116T/116U) Low pressure pumps (options 116T/116U)
Fluid pressure is measured by pressure sensors fitted at pump operation of the pump. Carrier does not undertake the inlet and unit outlet. The system calculates the flow rate accuracy of this information.

WARNING: Operation of the chiller with an improper supply voltage or excessive phase imbalance constitutes abuse which will invalidate the Carrier warranty. If the phase imbalance exceeds 2% for voltage, or 10% for current, immediately contact your local electricity supply at once and ensure that the chiller is not switched on until corrective measures have been taken .
