SAFETY SUMMARY

Do not install the indoor unit, outdoor unit, remote control switch and cable within
approximately 3 meters from strong electromagnetic wave radiators such as medical
equipment.

Supply electrical power to the system to energize the oil heater for 12 hours before
start-up after a long shutdown.

Do not step or put any material on the product.

Provide a strong and correct foundation so that;
a. The outdoor unit is not on an incline.
b. Abnormal sound does not occur.
c. The outdoor unit will not fall down due to a strong wind or earthquake.

NOTE:

It is recommended that the room be ventilated every 3 to 4 hours.

The heating capacity of the heat pump unit is decreased according to the outdoor air
temperature.  Therefore, it is recommended that auxiliary heating equipment be used in
the field when the unit is installed in a low temperature region.
