• PMV Kit side:
A position 500 mm or less away from the shell of the PMV Kit body.
• Indoor unit side: A position between the PMV Kit body and the existing clamp filter and adjacent to the existing
clamp filter.
1) ~2) Perform the same process as 1) and 2) of Work procedure 1.
3) Be sure to install a clamp filter (accessory) on the PMV Kit side. The operation in this step is the same as the
operation in step 3) of Work procedure 1.
4) Open the electrical parts box cover of the indoor unit after power-off and then process wiring work.
For details, refer to the Installation Manual attached to the indoor unit.
5) Replace the PMV connector built in the indoor unit with the connection cable of PMV Kit.
The lock mechanism is provided at side of PMV connector. Remove the connector by releasing the lock
mechanism.
6) Be sure to install another clamp filter (accessory) on the indoor unit side. The operation in this step is the same
as the operation in step 3) of Work procedure 1.
7) The clamp filter (accessory) to be installed on the indoor unit side must be placed in the specified position as
shown in the picture (next page) and then the PMV Kit connection cable must be routed appropriately.
8) Fix the connection cable of PMV Kit with cord clamp for existing wiring.
NOTE
• Follow steps 6), 7), and 8) so that the portions of the cable before and after each of the clamp filters, including
the one already installed in the electrical parts box, do not come into contact with each other.
• When an air-conditioner is operated, with a clamp filter (accessories) not attached, it may become the
malfunction of an electronic device and the cause of failure in the circumference.
