Selection Of Installation Location; Refrigerant Piping; Electrical Wiring - Toshiba RAV-GM2241AT8-E Installationsanleitung

Selection of installation location

• If you install the unit in a small room, take appropriate measures to
prevent the refrigerant from exceeding the limit concentration even if
it leaks. Consult the dealer from whom you purchased the air
conditioner when you implement the measures. Accumulation of
highly concentrated refrigerant may cause an oxygen deficiency
accident.
• Do not install the air conditioner in a location that may be subject to a
risk of expire to a combustible gas. If a combustible gas leaks and
becomes concentrated around the unit, a fire may occur.
• When transporting the air conditioner, wear shoes with additional
protective toecap.
• When transporting the air conditioner, do not take hold of the bands
around the packing carton. You may injure yourself if the bands
should break.
• Do not place any combustion appliance in a place where it is directly
exposed to the wind of air conditioner, otherwise it may cause
imperfect combustion.
• Do not install the air conditioner in a poorly ventilated space that is
smaller than the minimum floor area (Amin).
This applies to:
•Indoor units
•Outdoor units installed
(example: winter garden, garage, machinery room, etc.)
Refer to "15. Appendix - [2] Minimum floor area: Amin (m
determine the minimum floor area.
Installation
• Install the air conditioner at enough strong places to withstand the
weight of the unit. If the strength is not enough, the unit may fall down
resulting in injury.
• Follow the instructions in the Installation Manual to install the air
conditioner. Failure to follow these instructions may cause the
product to fall down or topple over or give rise to noise, vibration,
water leakage, etc.
• The designated bolts (M10) and nuts (M10) for securing the outdoor
unit must be used when installing the unit.
• Install the outdoor unit property in a location that is durable enough to
support the weight of the outdoor unit. Insufficient durability may
cause the outdoor unit to fall, which may result in injury.

• If refrigerant gas has leaked during the installation work, ventilate the
room immediately. If the leaked refrigerant gas comes in contact with
fire, noxious gas may be generated.
• The installation of pipe work shall be kept to a minimum.

Refrigerant piping

• Install the refrigerant pipe securely during the installation work before
operating the air conditioner. If the compressor is operated with the
valve open and without refrigerant pipe, the compressor sucks air and
the refrigeration cycles is over pressurized, which may cause a injury.
• Tighten the flare nut with a torque wrench in the specified manner.
Excessive tighten of the flare nut may cause a crack in the flare nut
after a long period, which may result in refrigerant leakage.
• For installation and relocation work, follow the instructions in the
Installation Manual and use tools and pipe components specifically
made for use with R32 refrigerant. If pipe components not designed
for R32 refrigerant are used and the unit is not installed correctly, the
pipes may burst and cause damage or injuries. In addition, water
leakage, electric shock, or fire may result.
• Nitrogen gas must be used for the airtight test.
• The charge hose must be connected in such a way that it is not slack.

Electrical wiring

• Only a qualified installer (*1) or qualified service person (*1) is
allowed to carry out the electrical work of the air conditioner. Under
no circumstances must this work be done by an unqualified individual

)" to
since failure to carry out the work properly may result in electric
shocks and/or electrical leaks.
• The appliance shall be installed in accordance with national wiring
regulations. Capacity shortages of the power circuit or an incomplete
installation may cause an electric shock or fire.
• Use wiring that meets the specifications in the Installation Manual and
the stipulations in the local regulations and laws. Use of wiring which
does not meet the specifications may give rise to electric shocks,
electrical leakage, smoking and/or a fire.
• Be sure to connect earth wire. (Grounding work) Incomplete earthing
causes an electric shock.
• Do not connect earth wires to gas pipes, water pipes, and lightning
rods or earth wires for telephone wires.
• After completing the repair or relocation work, check that the ground
wires are connected properly.
• Install a circuit breaker that meets the specifications in the installation
manual and the stipulations in the local regulations and laws.
