3.
Connect the 2-pin wiring harness( ) to the interface module at CN83 (Figure 2) and to the outdoor
unit at "GAS LEAK" connector (Main PCB).
4.
Connect the 4-pin wiring harness( ) to the interface module at CN81 (Figure 2) and to the outdoor
unit at "PUMP DOWN" connector (Main PCB).
5.
Restore power to the outdoor unit.
Shut off power to the outdoor unit before wiring the module.
WARNING
• Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout
procedures to ensure the power cannot be inadvertently energized. Failure to disconnect power before
servicing could result in death or serious injury.
Installation option setting of outdoor unit

About interface module
MIM-B14A is an interface module that has 2 outputs and 1 input. It is mainly applied to refrigerant leak detector system.
External Contact Interface Module (MIM-B14A)
Example of refrigerant leak detector operation
Figure 3. External contact interface module wiring diagram
1.
The refrigerant leak detection signal is sent to the outdoor unit - through the DDC RL#2 port.
2.
The lock signal of the high pressure valve is output from the - port of the outdoor unit.
3.
The lock signal of the low pressure valve is output from the - port of the outdoor unit.
