Electrical Work - Toshiba RAV-GM1101ATP-E Installation Manual

Gas leak inspection
Use a leak detector manufactured specially for HFC refrigerant
(R32, R410A, R134a, etc.) to perform the R32 gas leak inspection.
* Leak detectors for conventional HCFC refrigerant (R22, etc.)
cannot be used, as the sensitivity drops to approximately 1/40
when used for HFC refrigerant.
• R32 has a high working pressure, so failure to perform the installation
work properly may result in gas leaks such as when the pressure
rises during operation. Be sure to perform leak tests on the piping
connections.
Insulating the Pipes
■
• The temperatures at both the liquid side and gas
side will be low during cooling so in order to prevent
condensation, be sure to insulate the pipes at both
of these sides.
Insulate the pipes separately for the liquid side and
•
gas side.
Insulate the branch pipes by following the
•
instructions in the installation manual provided with
the branch pipe kit.

REQUIREMENT
Be sure to use an insulating material which can
withstand temperatures above 120°C for the gas
side pipe since this pipe will become very hot during
heating operations.

WARNING
1
Using the specified wires, ensure that the
wires are connected, and fix wires securely
so that the external tension to the wires does
not affect the connecting part of the
terminals.
Incomplete connection or fixation may cause a
fire, etc.
2
Be sure to connect the earth wire.
(grounding work)
Incomplete grounding may lead to electric
shock.
Do not connect ground wires to gas pipes, water
pipes, lightning rods or ground wires for telephone
wires.
3
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.
CAUTION
An installation fuse must be used for the power supply
line of this air conditioner.
Incorrect / incomplete wiring may lead to an electrical
fire or smoke.
Prepare an exclusive power supply for the air
conditioner.
This product can be connected to the mains power.
Fixed wire connections:
A switch that disconnects all poles and has a contact
separation of at least 3 mm must be incorporated in
the fixed wiring.
Be sure to use the cord clamps attached to the
product.
Do not damage or scratch the conductive core or inner
insulator of the power and system interconnection
wires when peeling them.
Use the power and system interconnection wires with
specified thicknesses, specified types and protective
devices required.
– 16 –
Remove the service panel, and you can see electric
parts on the front side.
A conduit pipe can be installed through the hole for
wiring. If the hole size does not fit the wiring pipe to
be used, drill the hole again to an appropriate size.
Be sure to clamp the power wires and system
interconnection wires with a banding band along the
connecting pipe so that the wires do not touch the
compressor or discharge pipe.
(The compressor and the discharge pipe become
hot.)
