ENGLISH
HAND OVER
Teach the customer the operation and maintenance procedures, using the operation manual
(air filter cleaning, temperature control, etc.).
CAUTION
After the confirmation of the above conditions, prepare the wiring as follows:
1
Never fail to have an individual power specialized for the air conditioner. As for the method of
wiring, be guided by the circuit diagram pasted on the inside of control box cover.
2
Provide a circuit breaker switch between power source and the unit.
3
The screw which fasten the wiring in the casing of electrical fittings are liable to come loose
from vibrations to which the unit is subjected during the course of transportation. Check
them and make sure that they are all tightly fastened. (If they are loose, it could give rise to
burn-out of the wires.)
4
Specification of power source
5
Confirm that electrical capacity is sufficient.
6
Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage
marked on the name plate.
7
Confirm that the cable thickness is as specified in the power sources specification.
(Particularly note the relation between cable length and thickness.)
8
Never fail to equip a leakage breaker where it is wet or moist.
9
The following troubles would be caused by voltage drop-down.
- Vibration of a magnetic switch, damage on the contact point there of fuse breaking, distur-
bance to the normal function of a overload protection device.
- Proper starting power is not given to the compressor.
10
Use only 1 remote-controller contained in indoor unit, when using simultaneous operation
system as shown below.
After setting the ESP value in the Ceiling Concealed Duct Type Indoor Unit, the main power
turns off and then remove the remote controller. (Only for synchro combination, over
36kBtu/h)
