Toshiba RAS-M10SMUV-E Installation Manual page 6

• When the air conditioner is installed in a small room, provide appropriate measures to ensure that in the event of a refrigerant
leak the rooms does not exceed the critical level.
• Install the air conditioner securely in a location where the base can sustain the weight of the unit adequately.
• Perform the specified installation work to guard against an earthquake.
If the air conditioner is not installed appropriately, accidents may occur due to the unit falling.
• If refrigerant gas has leaked during the installation work, ventilate the room immediately.
If the leaked refrigerant gas comes in contact with fire, noxious gases may be generated.
• After the installation work, confirm that refrigerant gas does not leak.
If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gases maybe generated.
• Use only the specified wiring during the unit installation. Ensure that all terminals are securely fixed, so preventing any
external forces having a negative effect on the terminals.
• Be sure to provide grounding.
Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone cables.
• Do not install the air conditioner in a location that maybe subjected to a risk of exposure to a combustible gas.
If a combustible gas leaks and becomes concentrated around the unit, a fire may occur.
• Do not install in locations where the unit will get splashed by water or with high humidity such as bathrooms. This can cause
deterioration of the insulation, resulting in an electric shock or fire.
• Check the following points before starting operation in the installation work.
- The pipes are securely connected and do not leak.
- The service valve is opened.
Operating the compressor while the service valve is closed will result in an abnormally high pressure, and can possibly
damage the compressor and other parts. Also, any leaks in the connections can cause air to be sucked in, resulting in an
even higher abnormally pressure, and can cause a pipe rupture or injury.
• When carrying out the pump-down work, shut down the compressor before disconnecting the refrigerant pipe. Disconnecting
the refrigerant pipe with the service valve left open and with the compressor still operating will cause air, etc. to be sucked in,
raising the pressure inside the refrigeration cycle to an abnormally high level, and possibly resulting in rupturing, injury, etc.
CAUTION
• Wear work gloves when carrying out the installation work or repairs. Contact with parts, etc. may cause injury if the work or
repairs are conducted without wearing gloves.
• Earth leakage breakers are required in certain installation locations. Failure to install the earth leakage breakers can result in
an electric shock.
• The pipes for the drain work should be installed properly in accordance with the installation manual to ensure proper
draining. Failure to install the pipes properly can cause a leak indoors and wet the furniture and other objects in the home.
• Tighten the flare nut with a torque wrench using the specified method. If the flare nut is over-tightened, it can crack over a
long period of time, resulting in a refrigerant leak.
• Do not touch the inlets or aluminum fins of the indoor and outdoor unit. An injury could result.
• Do not install the outdoor unit where small animals typically live. If small animals get inside the unit and touch the electrical
parts, a failure or fire can result. Also, please keep the area around the outdoor unit clear of fallen leaves and other objects.
• After the installation work is completed, perform test operation to check that there is nothing abnormal, and explain to the
customer the operating and cleaning procedures based on the owner's manual. Also, ask the customer to store this
installation manual together with the owner's manual.
