Toshiba RAS-07PKVP-E Installation Manual page 4

• WHEN INSTALLING OR RE-INSTALLING THE AIR CONDITIONER, DO NOT INJECT AIR OR OTHER SUBSTANCES
BESIDES THE DESIGNATED REFRIGERANT "R410A" INTO THE REFRIGERATING CYCLE. IF AIR OR OTHER
SUBSTANCES ARE MIXED, AN ABNORMAL PRESSURE CAN OCCUR IN THE REFRIGERATING CYCLE, AND THIS
CAN CAUSE AN INJURY DUE TO A PIPE RUPTURE.
• Installation work must be requested from the supplying retail dealership or professional vendors. Self-installation may cause
water leakage, electrical shock, or fire as a result of improper installation.
• Specified tools and pipe parts for model R410A are required, and installation work must be done in accordance with the
manual. HFC type refrigerant R410A has 1.6 times more pressure than that of conventional refrigerant (R22). Use the
specified pipe parts, and ensure correct installation, otherwise damage and/or injury may be caused. At the same time,
water leakage, electrical shock, and fire may occur.
• Be sure to install the unit in a place which can sufficiently bear its weight. If the load bearing of the unit is not enough, or
installation of the unit is improper, the unit may fall and result in injury.
• Electrical work must be performed by a qualified electrical engineer in accordance with the code governing such installation
work, internal wiring regulations, and the manual. A dedicated circuit and the rated voltage must be used. Insufficient power
supply or improper installation may cause electrical shock or fire.
• Use a cabtyre cable to connect wires in the indoor/outdoor units. Midway connection, stranded wire, and single-wire
connections are not allowed. Improper connection or fixing may cause a fire.
• Wiring between the indoor unit and outdoor units must be well shaped so that the cover can be firmly placed. Improper cover
installation may cause increased heat, fire, or electrical shock at the terminal area.
• Be sure to use only approved accessories or the specified parts. Failure to do so may cause the unit to fall, water leakage,
fire or electrical shock.
• After the installation work, ensure that there is no leakage of refrigerant gas. If the refrigerant gas leaks out of the pipe into
the room and is heated by fire or something else from a fanheater, stove or gas range, it causes generation of poisonous
gas.
• Make sure the equipment is properly earthed. Do not connect the earth wire to a gas pipe, water pipe, lightning conductor, or
telephone earth wire. Improper earth work may be the cause of electrical shock.
• Do not install the unit where flammable gas may leak. If there is any gas leakage or accumulation around the unit, it can
cause a fire.
• Do not select a location for installation where there may be excessive water or humidity, such as a bathroom. Deterioration of
insulation may cause electrical shock or fire.
• Installation work must be performed following the instructions in this installation manual. Improper installation may cause
water leakage, electrical shock or fire. Check the following items before operating the unit.
- Be sure that the pipe connection is well placed and there are no leaks.
- Check that the service valve is open. If the service valve is closed, it may cause overpressure and result in compressor
damage. At the same time, if there is a leak in the connection part, it may cause air suction and overpressure, resulting in
damage to the unit or injury.
• In a pump-down operation, be sure to stop the compressor unit before removing the refrigerant pipe. If removing the
refrigerant pipe while the compressor is operating with the service valve opened, it may cause air suction and overpressure,
resulting in damage to the unit or injury.
• Do not modify the power cable, connect the cable midway, or use a multiple outlet extension cable. Doing so may cause
contact failure, insulation failure, or excess current, resulting in fire or electrical shock.
• If you detect any damage, do not install the unit. Contact your supplying dealer immediately.
• Never modify this unit by removing any of the safety guards or bypassing any of the safety interlock switches.
• Please read this installation manual carefully before installing the unit. It contains further important instructions for proper
installation.
• Exposure of unit to water or other moisture before installation could result in electric shock. Do not store it in a wet basement
or expose to rain or water.
• After unpacking the unit, examine it carefully for possible damage.
• Do not install in a place that can increase the vibration of the unit. Do not install in a place that can amplify the noise level of
the unit or where noise and discharged air might disturb neighbors.
• This appliance must be connected to the main power supply by means of a circuit breaker depending on the place where the
unit is installed. Failure to do so may cause electrical shock.
• Follow the instructions in this installation manual to arrange the drain pipe for proper drainage from the unit. Ensure that
drained water is discharged. Improper drainage can result in water leakage, causing water damage to furniture.
• Tighten the flare nut with a torque wrench using the prescribed method. Do not apply excess torque. Otherwise, the nut may
crack after a long period of usage and it may cause the leakage of refrigerant.
