・
For the remote operation, turn on and off the power supply side under the condition of the Switch with
lamp ON.
・
Ensure at least 3 minutes is left after the unit is stopped before restarting it, even for the remote operation.
If the product is restarted within less than 3 minutes, protective equipment (overload relay) may activate
and prevent the product from restarting.
Additionally, the frequency to start and stop the operation must be restricted to 5 times per hour (to
prevent breakage of the motor).
Only qualified person must perform wiring and observing the following points.
1. Be sure to shut off the power supply before wiring. For safety, do not perform any work on the unit with
the power supply on. The power supply cannot be completely shut off just by turning off the Switch with
lamp. Be sure to turn off all power lines connected to the product.
2. Supply the power from a stable source, free from surges.
3. Be sure to mount the Ground Fault Circuit Interrupter (GFCI) with adequate sensitivity and load
capacity to prevent electrical shock and protect the refrigerating compressor motor from burning out.
4. Provide the power suitable for the product specifications.
5. Be sure to ground the product for safety. Without grounding, the GFCI can not operate normally.
6. Do not ground to water pipe, gas tube or lightening rod line.
7. Do not connect too many wires to the same outlet, which could results in heat generation and fire.
8. Do not retrofit the wiring of the dryer and the power supply line.
9. For the use of the product in Europe, mount the breaker compatible to IEC standard to the power supply
for the product.
