Read the following precautions thoroughly before the maintenance, and then inspect and repair the product in a
safe manner.
The types and levels of danger that may arise if the product is handled incorrectly are described with the warning
symbols shown below.
Warning
Modification is prohibited
Do not modify the unit.
( Failure to observe this warning may
result in electric shock, fire and/or injury. )
Electric shock
If you must inspect the circuitry while the power is
on, do not touch the live parts.
(Failure to observe this warning may
result in electric shock.)
Check insulation
Upon completing repair work, always measure the insula-
tion resistance. Verify that it is at least 10 MΩ(with a 500
V DC insulation resistance tester), and then turn on the
power.
(Inadequate insulation may result in
electric shock.)
Improper handling of the product may
result in serious injury or death.
Caution Improper handling of the product may result in injury or
damage to properties including buildings and equipment.
Proper electric work
Use the electric wires designated for electric work,
and conduct electric work in accordance with your
local electric work regulations and the installation
manual.
(Improper connection or wiring installation
may result in electric shock and/or fire.)
Replace damaged and/or degraded parts
Be sure to replace the power cord and lead wires if
they are damaged and/or degraded.
(Failure to observe this warning may
result in electric shock and/or fire.)
Use proper parts and tools
For repair, be sure to use the parts listed in the parts
catalog of the applicable model and use the proper
tools.
(Failure to observe this warning may
result in electric shock, fire and/or injury.)
Caution against
electric shock
Prohibited
Turn off the power supply
Be sure to shut off the circuit breaker before
disassembling the unit for repair.
(Failure to observe this warning may
result in electric shock.)
Make sure that the product operates properly upon completion of repair. Clean the product and the surrounding
area, and then notify the customer of the completion of repair.
Caution for injury
Do not work at a location where you do not have a
sure footing.
( Failure to observe this caution may result
in a fall. )
Notes for servicing
●Inspect the grounding, and repair it if it is incomplete. Make sure that an earth leakage breaker is installed, if it
is not installed, install one.
Be sure to follow
this instruction.
Wear gloves
Wear a pair of gloves when servicing.
(Failure to observe this caution may
result in injury.)

(1) Turn off the power supply.
[1] Turn off the external ON/OFF switch.
[2] Turn off the circuit breaker.
[3] Disconnect the power wires from the terminal block.
10. Overhauling procedures
Work precautions
• Before replacing parts or components, follow the instructions described in the troubleshooting.
• When servicing, always keep proper footing.
• When servicing, always unplug the power cord from the outlet, or turn off the circuit breaker. Pay sufficient
attention to avoid electric shock or injury.
• Make sure to connect the power supply wires correctly.
• Avoid application of abnormal voltage.
• Pay attention not to drop the parts or components.
• After completing repairs, check that the product operates properly.
• Servicing at a high place must be performed by two workers.
• For the parts provided with tightening torques, tighten them with the specified tightening torques.
Always wear a pair of gloves when servicing.
The part names in the text are standardized with the part names in the parts catalog. (There are some
exceptions.)
Note: The pictures and illustrations show AH-1509S1-E.
Precaution
Before replacing the parts or components, dismount the main unit of the product.
Working at the high place causes a danger if the parts or components are replaced without dismounting the unit.
Precaution
The circuit breaker must be turned off before disconnecting the power wires.

(2) Remove the motor.
[1] Unscrew the screws (two PP screws 4x6, indicated
by ), and remove the under cover.
[2] Identify the faulty motors.
a. If one of the motors is not working, replace the motor.
b. If multiple motors are not working, identify the faulty motors by the following procedures.
• For example, if the motors surrounded by are not working
Precaution
When cutting the crimp caps, keep the length of the lead wires as long as possible. If the lead wires
are too short, they cannot be reconnected after the replacement.
When the coil resistance at ordinary temperatures is equivalent to the values below, the motor is normal.
Measure the resistance of all the motors that are not working to identify the faulty motors.
Cut the crimp caps (indicated by ) at the position indicated by , and measure the coil resistance
between the lead wires of each motor.
