Precautions on Installation
Precautions for Selecting the Location
1) Choose a place strong enough to bear the weight and vibration of the unit, The location should not amplified the
unit noise.
2) Choose a location where the hot air discharged from the unit and the operationing noise will not be a nuisance
to the neighbors.
3) Avoid noise sensitive locations such as bedrooms to avoid future problems.
4) There must be sufficient clearance for carrying the unit into and out of the site.
5) There must be sufficient space around the air inlet and the air outlet with no obstructions to airflow.
6) The surrounding area must be free from the possibility of flammable gas leakage.
7) Install units, power cords and inter-connecting cables at least 10 feet away from television and radio sets. This
is to prevent interference to images and sounds. (Noises may be heard even if they are more than 10 feet away
depending on radio wave conditions.)
8) In coastal areas or other places with salty atmosphere of sulfate gas, corrosion may shorten the life of the air
conditioner.
9) Do not place moisture sensitive equipment or articles under the outdoor unit condenstate drain.
NOTE
Do not install unit by hanging from a ceiling or stacking units.
When operating the air conditioner in a outdoor temperature below,
be sure to follow the instructions described below.
1) To prevent exposure to wind, install the outdoor unit with its
suction side facing the wall.
2) Never install the outdoor unit at a site where the suction side
may be exposed directly to wind.
3) To prevent exposure to wind, it is recommended to install a baffle
plate on the air discharge side of the outdoor unit.
4) In heavy snowfall areas, select an installation site where the snow
will not affect the unit.
• Ensure the strength and level of the installation will not cause any operating vibration or noise after installed.
• In accordance with the foundation drawing, fix the unit securely by means of the foundation bolts. (Prepare four
sets of 3/8” or 7/16” foundation bolts, nuts and washers each which are available on the market.)
• It is best to screw in the foundation bolts until their length are 3/4” from the foundation surface.

Failure to follow any of CAUTION may in some cases result in grave consequences.
• The following safety symbols are used throughout this manual:
Be sure to observe this instruction.
Be sure to establish a proper
earth grounding connection.
Never attempt.
•
After completing installation, test the unit to check for installation errors. Give the user adequate instructions concerning the use and cleaning of the unit according to the Operation Manual.
•
Installation should be left to the authorized dealer or another trained professional.
Improper installation may cause water leakage, electrical shock, fire, or equipment damage.
•
Install the air conditioner according to the instructions given in this manual.
Incomplete installation may cause water leakage, electrical shock, fire or equipment damage.
•
Be sure to use the supplied or exact specified installation parts.
Use of other parts may cause the unit to come to lose, water leakage, electrical shock, fire or equipment damage.
•
Install the air conditioner on a solid base that is level and can support the unit's weight.
An inadequate base or incomplete installation may cause injury or equipment damage in the event the unit falls off the base or comes loose.
•
Electrical work should be carried out in accordance with the installation manual and the national, state and local electrical wiring codes.
Insufficient capacity or incomplete electrical work may cause electrical shock, fire or equipment damage.
•
Be sure to use a dedicated power circuit. Never use a power supply shared by another appliance. Follow all appropriate electrical codes.
•
Use the specified types of wires for electrical connections between the indoor and outdoor units. Follow all state and local electrical codes.
Firmly clamp the interconnecting wires so their terminals receive no external stresses. Incomplete connections or clamping may cause terminal overheating, fire or euipment damage.
• After all installation is complete, check to make sure that no refrigerant is leaking.
(The refrigerant produces a toxic gas if exposed to flames.)
• Do not install the air conditioner where gas leakage would be exposed to open flames.
If the gas leaks and builds up around the unit, it may catch fire.
• Establish drain piping according to the instructions of this manual. Inadequate piping may cause water damage.
•
Tighten the flare nut according to the specified torque. A torque wrench should be used.
If the flare nut is tightened too much, the flare nut may crack over time and cause refrigerant leakage.
•
Be very careful about product transportation.
Some products use PP bands for packaging. Do not use any PP bands for a means of transportation. It is dangerous.
• Never perform outdoor unit piping connection work when it is raining.
•
Make sure to provide for adequate measures in order to prevent that the outdoor unit be used as a shelter by small animals.
Small animals making contact with electrical parts can cause malfunctions, smoke or fire. Please instruct the customer to keep the area around the unit clean.
•
Note for installing the outdoor unit. (For heat pump model only.) In regions of the country where the outside temperature is at or
below the freezing point, the drain may freeze. If so, it is recommended that an electric heater be installed in order to protect the drain from freezing.
•
After connecting all wiring be sure to shape the cables so that they do not put undue stress on the electrical covers, panels or terminals.
Install covers over the wires. Incomplete cover installation may cause terminal overheating, electrical shock,fire or equipment damage.
•
When installing or relocating the system, be sure to keep the refrigerant circuit free from all substances other than the specified refrigerant (R410A), such as air.
(Any presence of air or other foreign substance in the refrigerant circuit causes an abnormal pressure rise which may result in rupture, resulting in injury.)
• If any refrigerant has leaked out during the installation work, ventilate the room.
(The refrigerant produces a toxic gas if exposed to flames.)
• Be sure to establish a ground. Do not ground the unit to a utility pipe, arrester, or telephone ground.
Incomplete or inadequate grounding may cause equipment damage, or electrical shock, fire and personal injury. A high surge current from lightning or other sources may cause damage to the air conditioner.
•
Securely install the outdoor unit terminal cover (panel).
If the terminal cover (panel) is not installed properly, dust or water may enter the outdoor unit and fire or electric shock may reslt.
• Install an leak circuit breaker, as required. If an leak circuit breaker is not installed, electric shock may result.
•
Be sure to install a ground fault circuit interrupter breaker.
Failure to install a ground fault circuit interrupter breaker may result in electrically shocks, fire or personal injury.
•
During pump-down, stop the compressor before removing the refrigerant piping.
If the compressor is still running and the shut-off valve is open during
pump-down, air will be sucked in when the refrigerant piping is removed, causing abnormally high pressure which could lead to equipment damage or and personal injury.
•
During installation, attach the refrigerant piping securely before running the compressor.
If the compressor is not attached and the shut-off valve is
open during pump-down, air will be sucked in when the compressor is run, causing abnormally high pressure whichcould lead to equipment damage and personal injury.
•
For wiring, use a wire or cable long enough to cover the entire distance with no splices if possible. Do not use an extension cord. Do not put other
loads on the power supply.Use a only a separate dedicated power circuit.
(Failure to do so may cause abnormal heat, electric shock,fire or equipment damage.)
