WARNING
General
• Do not modify the products. Do not also disassemble or modify the parts. It may cause a re,
electric shock or injury.
• Before starting to install the Dx-coil interface, read through the Installation Manual carefully,
and follow its instructions to install the Dx-coil interface.
• Only a qualied installer or qualied service person is allowed to do installation work.
Inappropriate installation may result in water leakage, electric shock or re.
• Do not use any refrigerant different from the one specied for complement or replacement.
Otherwise, abnormally high pressure may be generated in the refrigeration cycle, which may
result in a failure or explosion of the product or an injury to your body.
• Before opening the electrical control box cover of the air handling unit or service panel of the
outdoor unit, set the circuit breaker to the OFF position. Failure to set the circuit breaker to
the OFF position may result in electric shocks through contact with the interior parts. Only
a qualied installer (*1) or qualied service person (*1) is allowed to remove the electrical
control box cover of the air handling unit or service panel of the outdoor unit and do the work
required.
• Before carrying out the installation, maintenance, repair or removal work, set the circuit
breaker to the OFF position. Otherwise, electric shocks may result.
• Place a “Work in progress” sign near the circuit breaker while the installation, maintenance,
repair or removal work is being carried out. There is a danger of electric shocks if the circuit
breaker is set to ON by mistake.
• Only a qualied installer (*1) or qualied service person (*1) is allowed to undertake work at
heights using a stand of 50 cm or more.
• Wear protective gloves and safety work clothing during installation, servicing and removal.
• When work is performed at heights, use a ladder which complies with the ISO 14122
standard, and follow the procedure in the ladder’s instructions. Also wear a helmet for use in
industry as protective gear to undertake the work.
• Before working at heights, put a sign in place so that no-one will approach the work location,
before proceeding with the work. Parts and other objects may fall from above, possibly injuring
a person below. While carrying out the work, wear a helmet for protection from falling objects.
• The refrigerant used by this Dx-coil interface is the R410A.
• The Dx-coil interface must be transported in stable condition. If any part of the product is
broken, contact the dealer.
• Do not move or repair any unit by yourself. There is high voltage inside the unit. You may get
electric shock when removing the cover and main unit.
• This appliance is intended to be used by expert or trained users in shops, in light industry, or
for commercial use by lay persons.
• Do not add any other devices without factory advice.
Installation
• Install the air conditioner securely in a location where the base can sustain the weight
adequately. If the strength is not enough, the unit may fall down resulting in injury.
• Follow the instructions in the Installation Manual to install the air conditioner. Failure to follow
these instructions may cause the product to fall down or topple over or give rise to noise,
vibration, water leakage or other trouble.
• Carry out the specied installation work to guard against the possibility of high winds and
earthquake.
If the air conditioner is not installed appropriately, a unit may topple over or fall down,
causing an accident.
