Electrical Connection - Toshiba RAV-RM301SDT-E Manual De Instalación

◆ Gas leak check
Check with a leak detector or soap water whether gas leaks
or not, from the pipe connecting section or cap of the valve.
REQUIREMENT
Use a leak detector manufactured exclusively for HFC
refrigerant (R32, R410A, R134a, etc.).
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, 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 earthing 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.
• Under no circumstances, the power supply wire or the indoor and outdoor connecting wire must not be
connected in the middle (Connection using a solderless terminal etc.)
Connection trouble in the places where the wire is connected in the middle may give rise to smoking and/or a fire.
CAUTION
• For power supply specifications, follow the Installation Manual of outdoor unit.
• Do not connect 220 – 240 V 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 during
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.
