Forced drain pump operation
♦
Setup from a unit side.
Turn power on after selecting the emergency operation mode with a setting on the indoor unit control PCB (SW9-3 ON) and
disconnecting the CnB connector on the board. Then, the drain pump will start a continuous operation 15 seconds later.
(Note: The blower will also start operation in tandem)
When a drain test is completed, reinstate the setting to cancel the emergency operation mode (SW9-3 OFF) and plug in the CnB
connector on the board.
(When electrical work is not completed, connect a convex joint to the drain pipe joint area, arrange an inlet and check leaks and drain
conditions of the pipe. )
♦
Setup from a remote controller side.
Drain pump operation from a remote controller unit is possible. Operate a remote controller unit by following the steps described
below.
1. To start a forced drain pump operation
Press the TEST button for three seconds or longer.
The display will change from “
SELECT ITEM”
“
SET”
“
TEST RUN
”
Press the
button once while “
TEST RUN
” is displayed, and cause “DRAIN PUMP ” to be displayed.
When the SET button is pressed, a drain pump operation will start.
Display: “DRAIN PUMP RUN”
“
STOP”
2. To cancel a drain pump operation.
If either SET or ON/OFF button is pressed, a forced drain pump
operation will stop.
The air conditioning system will become OFF.
10) Drainage from the lower drain socket
Only if the drain pipe can be installed in a downhill
grade (1/50-1/100), the lower drain socket can be used
for connecting to the drain pipe as illustrated.
(Disconnect the connector for the drain motor)
As shown in the sketch to the right, disconnect the drain
motor connector CnR ( blue color coding).
If the system is started with this connector connected
as is, drain water is discharged out of the upper drain
socket causing a heavy water lekage.
