WIRED REMOTE CONTROLLER INSTALLATION
• Since the room temperature sensor is in the remote controller, the remote controller box should be installed in a place away from
direct sunlight, high humidity and direct supply of cold air to maintain proper space temperature.
Install the remote controller about 5ft(1.5m) above the floor in an area with good air circulation at an average temperature.
Do not install the remote controller where it can be affected by:
- Drafts, or dead spots behind doors and in corners.
- Hot or cold air from ducts.
- Radiant heat from sun or appliances.
- Concealed pipes and chimneys.
- Uncontrolled areas such as an outside wall behind the remote controller.
- This remote controller is equipped with a seven segment LED. display. For proper display of the remote controller LED's, the
remote controller should be installed properly as shown in Fig.1. (The standard height is 1.2~1.5 m from floor level.)

CAUTION
HAND OVER
Teach the customer the operation and maintenance procedures, using the operation manual (air filter cleaning, temperature control, etc.).
After the confirmation of the above conditions, prepare the wiring as follows:
1) Never fail to have separate power specially for the air conditioner. As for the method of wiring, follow 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) Confirm the 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) Do not install the leakage breaker in a place which is wet or moist.
Water or moist may cause short circuit.
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, disturbance to the normal function of a
overload protection device.
• Proper starting power is not given to the compressor.
