5 APPLICATION DATA

¡ Please read these "Safety Precautions" first then accurately execute the installation work.
¡ For installing qualified personnel, take precautions in respect to themselves by using suitable protective clothing, groves, etc., and
then perform the installation works.
¡ Though the precautionary points indicated herein are divided under two headings,
which are related to the strong possibility of an installation done in error resulting in death, serious injury or environmental
pollution are listed in the
the points listed in the
means, properly observe all that is mentioned.
¡ Please pay attention not to fall down the tools, etc. when installing the unit at the high position.
¡ After completing the installation, along with confirming that no abnormalities were seen from the operation tests. Please explain
operating methods as well as maintenance methods to the user (customer) of this equipment, based on the user's manual. Moreover,
ask the customer to keep this sheet together with the user's manual.
¡ If unusual noise can be heard during operation, consult the dealer.
¡
To disconnect the appliance from the mains supply this appliance must be connected to the mains by means of a circuit breaker or a
switch (use a recognized 16A) with a contact separation of at least 3mm.
¡
The appliance shall be installed in accordance with national wiring regulations.
¡
When a plug is connected to the power cord, a plug conforming to the IEC60884-1 standard must be used.
¡
This system should be applied to places as households, residences and the like. Application to inferior environment such as engineering
shop could cause equipment malfunction.
¡
Please entrust installation to either the company which sold you the equipment or to a professional contractor. Defects from improper
installations can be the cause of water leakage, electric shocks and fires.
¡
Execute the installation accurately, based on following the installation manual. Again, improper installations can result in water leakage,
electric shocks and fires.
¡
For installation, confirm that the installation site can sufficiently support heavy weight. When strength is insufficient, injury can result
from a falling of the unit.
¡
For electrical work, please see that a licensed electrician executes the work while following the safety standards related to electrical
equipment, and local regulations as well as the installation instructions, and that only exclusive use circuits are used.
Insufficient power source circuit capacity and defective installment execution can be the cause of electric shocks and fires.
¡
Accurately connect wiring using the proper cable, and insure that the external force of the cable is not conducted to the terminal
connection part, through properly securing it. Improper connection or securing can result in heat generation or fire.
¡
Take care that wiring does not rise upward, and accurately install the lid/service panel. It's improper installation can also result in heat
generation or fire.
¡
Always use accessory parts and authorized parts for installation construction. Using parts not authorized by this company can result in
water leakage, electric shock, fire and refrigerant leakage.
¡
Ventilate the work area when refrigerant leaks during the operation.
Coming in contact with fire, refrigerant could generate toxic gas.
¡
Confirm after the foundation construction work that refrigerant does not leak.
If coming in contact with fire of a fan heater, a stove or a movable cooking stove, etc., refrigerant leaking in the room could generate toxic gas.
¡
Turn off the power source during working on the inside of the unit such as servicing or installing work.
This may cause electric shock.
¡
Use only pipe, flare nut and tools that have been designed to operate with R410A.
Using existing parts (R22) may cause the unit failure, even as due to serious accident such as explosion of the cooling cycle or injury etc.
¡
For pump down work, stop the compressor before removing the refrigerant pipe.
If the refrigerant pipe is removed when the compressor is in operation with the service valves open (liquid side and gas side), air would
be mixed in the refrigerant circuit and this may cause explosion and injuries due to abnormal high pressure in the cooling cycle.
¡
Connect the pipes for refrigerant circuit securely in installation work before compressor is operated
If the compressor is operated when the service valve is open without connecting the pipe, this may cause frostbite and injuries due to
refrigerant leakage rapidly. Also, the unit is absorbed the air etc., this may cause explosion and injuries due to abnormal high pressure
in the cooling cycle.
¡
Tighten the flare nut by torque wrench with specified method.
If the flare nut were tightened with excess torque, this may cause burst and refrigerant leakage after a long period, and then, this may
cause generate the harmful substance due to touch the flammable materials.
¡
Make sure there is no dust or clogging on both plug and socket nor loose connection of the socket before plugging of the power plug.
Then, the power plug must be inserted tightly.
Accumulation of dust, clogging on the socket or plug, or loose installation of the socket may cause electric shock and fire. Replace the
socket if it is loose.
¡
Do not open the service valves (liquid side and gas side) until refrigerant piping construction, air-tightness test and evacuation are
completed.
This may cause frostbite and injuries due to refrigerant leakage rapidly. Also, if the refrigerant gas leakage occurs during installing work, stop
the work such as brazing work and then ventilation of the room. This may cause generate the toxic gas due to touch the flammable materia.
