installation technicians in accordance with the Installation Instructions provided
with the system controller.
•
Do not install this system controller where there are fumes or flammable gases,
or in an extremely humid space such as a greenhouse.
Do not install the system controller where excessively high heatgenerating
objects are placed.
WARNING
•
ELECTRICAL REQUIREMENTS
1. All wiring must conform to the local electrical codes. Consult your dealer or a qualified
electrician for details.
2. Wiring must be done by a qualified electrician.
To warm up the system, the power mains must be turned on at least five (5) hours
before operation. Leave the power mains ON unless you will not be using this
appliance for an extended period.
CAUTION
SAFETY INSTRUCTIONS
• Read this Operating Instructions carefully before using this system controller. If you
still have any difficulties or problems, consult your dealer for help.
• The air conditioner is designed to give you comfortable room conditions. Use this only
for its intended purpose as described in the Operating Instructions.
•
•
Never touch the unit with wet hands.
Never use or store gasoline or other flammable vapor or liquid near the air
conditioner — it is very dangerous.
The air conditioner has no ventilator for intaking fresh air from outdoors. You must
open doors or windows frequently when you use gas or oil heating appliances in the
same room, which consume a lot of oxygen from the air. Otherwise there is a risk of
suffocation in an extreme case.
WARNING
CAUTION
•
•
•
Do not turn the air conditioner on and off from the power mains switch. Use the ON/
OFF operation button.
Do not stick anything into the air outlet of the outdoor unit. This is dangerous
because the fan is rotating at high speed.
Do not let children play with the air conditioner.
Do not cool or heat the room too much if babies or invalids are present.
