For the MAC/M4AC080~150C/CR models, the water flows through the BPHE in one channel alone, while the refrigerant, due to the two compressors, flows through two more separate channels. Under abnormal conditions, the chiller panel controller will shut down the unit and then display the operating errors. The cooler control will force the unit into heat mode if the outside ambient air temperature becomes too cold.

To facilitate the controller, a rocker switch is provided to turn off the supply to the PCB. However, turning off the switch will not disconnect the main incoming power supply to the chiller unit.

When the Panel ID is set to '0' it will act as a Master panel, while it will be a Slave panel if the Panel ID is set to any other number (1-50). The main panel can choose to control each chiller or all chillers on the network at once. While powering up the chiller panel, it should take several times to gather information from the chiller.

When the process is complete, user can start controlling the chiller using the panel. Choose "Select All" and press ENTER if the user wants to control all Chilelr in the network, or choose "Select One". Select a chiller ID via UP or DOWN and press ENTER to confirm or ESC to cancel.

Viewing Alarm / Erase Alarm Record

When a new error/alarm occurs, a message will appear to show the error/alarm. If the fault/alarm is not resolved from the chiller, a sign [A] will be shown in the [Summary Pages] (from pop-up menu) automatically if the fault/alarms are resolved. While the error/alarms are not resolved (sign [A]), user can check that error/alarm by going to [Alarm Menu].

If all faults/alarms have been resolved, the user can also view the fault/alarm history records in [Alarm Menu]. If the panel ID is set to 0 (Master panel), it can receive and view all errors/alarms from all coolers in the network.

Special Precautions When Dealing With Refrigerant R407C Unit

What is new refrigerant R407C?

Components

Check list before installation/servicing

Precautions and Installation

This vacuum level is more stringent than the R22 system to ensure that there is no incompressible gas and moisture in the system. This is to ensure that only the original composition of R407C is supplied into the system. However, if the dip tube is not available, invert the cylinder or can to draw fluid out of the valve at the bottom. . g) When servicing leaks, the filling method commonly used for the R22 system is not recommended for the R407C system.

Unlike R22, where the refrigerant is a single component, the composition of R407C, which consists of three different components, may have changed during the leak. As a result, topping up may not ensure that the R407C in the system is of original composition.

Special Precautions When Dealing With Refrigerant R410A Unit

What Is New Refrigerant R410A?

Check List Before Installation / Servicing

This is to ensure that only the original composition of R410A is delivered to the system. However, if the riser tube is not available, you must invert the cylinder or can to draw fluid from the valve at the bottom.
