WARNING:
All electric work must be performed by a qualified technician according to local regulations and the instructions given
in this manual. The units must be powered by dedicated power lines and the correct voltage and circuit breakers must
be used. Power lines with insufficient capacity or incorrect electrical work may result in electric shock or fire.
Only the specified cables can be used for wiring, Connections must be made securely without tension on the terminals.
If cables are connected or installed improperly, it may result in overheating or fire.
Terminal block cover panel of the outdoor unit must be firmly fixed. If the cover panel is mounted improperly, dust
and moisture may enter the unit, and it may cause electric shock or fire.

may cause water leakage, electric shock or fire. If the FTC2 needs to be repaired or moved, ask an authorised
technician.
BEFORE INSTALLATION
CAUTION:
Do not install the FTC2 unit in an outdoor location as it is designed for indoor installation only. Otherwise electric
shock or breakdown may be caused by water, wind or dust.
Do not use the unit in an unusual environment. If the FTC2 unit is installed or exposed to steam or volatile oil
(including machine oil), or sulphuric gas, or exposed to briny air, the internal parts can be damaged.
Do not install the unit where combustible gases may leak, be produced, flow or accumulate. If combustible gas
accumulates around the unit, it may cause fire or explosion.
Do not wash the FTC2 unit. You may receive an electric shock.
BEFORE ELECTRIC WORK
CAUTION:
Be sure to install a circuit breaker. If it is not installed, there may be a risk of an electric shock.
For power lines, use standard cables of sufficient capacity. Otherwise, it may cause a short circuit, overheating, or fire.
When installing power lines, do apply tension to the cables. The cables may be cut or overheat, resulting in a fire.
Make sure to ground the unit. Do not connect the ground wire to gas or water pipes, lightning rods, or telephone
grounding lines. If the unit is not properly grounded, there may be a risk of electric shock.
Make sure to use circuit breakers (ground fault interrupter, isolating switch (+B fuse), and moulded case circuit
breaker) with the specified capacity. If the circuit breaker capacity is larger than the specified capacity, breakdown or
fire may result.
BEFORE STARTING THE TEST RUN
CAUTION:
Turn on the main power switch of the outdoor unit more than 12 hours before starting operation. Starting operation
immediately after turning on the power switch can severely damage the internal parts. Keep the main power switch
turned on during the operation period.
Before starting operation, check that all protective parts are correctly installed. Make sure not to get injured by
touching high voltage parts.
