Electrical Connection - Toshiba RAV-GM901BTP-E Installation Manual

Heat insulation process
Apply heat insulation for the pipes separately at liquid side and gas side.
For the heat insulation to the pipes at gas side, be sure to use the material with heat-resisting temperature
120°C or higher.
To use the attached heat insulation pipe, apply the heat insulation to the pipe connecting section of the indoor
unit securely without gap.
REQUIREMENT
Apply the heat insulation to the pipe connecting section of the indoor unit securely up to the root without
exposure of the pipe. (The pipe exposed to the outside causes water leak.)
Wrap heat insulator with its slits facing up (ceiling side).
Wrap the pipe with the attached heat insulator
without any gap between the indoor unit.
The seam must be faced upward

Electrical connection

WARNING
• Use the specified wires for wiring connect the terminals. Securely fix them to prevent external forces
applied to the terminals from affecting the terminals.
Incomplete connection or fixation may cause a fire or other trouble.
• Connect earth wire. (grounding work)
Incomplete grounding cause an electric shock.
Do not connect earth wires to gas pipes, water pipes, lightning conductor or telephone earth wires.
• Appliance shall be installed in accordance with national wiring regulations.
Capacity shortage of power circuit or incomplete installation may cause an electric shock or a fire.
CAUTION
For power supply specifi cations, follow the Installation Manual of outdoor unit.
Do not connect 220 – 240V power to the terminal blocks (
Otherwise, the system will fail.
• Do not damage or scratch the conductive core and inner insulator of power and system interconnection wires
when peeling them.
• Perform the electric wiring so that it does not come to contact with the high-temperature part of the pipe.
The coating may melt resulting in an accident.
• Do not turn on the power of the indoor unit until vacuuming of the refrigerant pipes completes.
