10-3. Work procedure after Repair
When vacuuming in the repaired outdoor unit, follow the procedure described below.
<Work procedure>
(1) Fully open PMV1 and 2 and PMV4 (MMY-MAP1404 and MAP1604 only) in accordance with the table below.
Note: PMV full-opening operation via short-circuiting of the CN30 pins is automatically undone after 2 minutes,
causing the valves to fully close. To maintain fully open state, turn off the power switch of the outdoor unit
within 2 minutes of the short-circuiting of the CN30 pins.
(2) Be sure to perform vacuuming in from the three check joints shown in the diagram below (liquid pipe, discharge
pipe and suction pipe).
