Refrigerant Piping
ALWAYS
Consult the Toshiba Installation manual before commencing installation of the outside unit and refrigerant
pipe work. If in doubt contact
Toshiba 24 hour Technical Helpline 0870 843 0333
Ensure that all refrigerant pipe is secured correctly, is within maximum pipe separation limits and is
correctly insulated. Do not operate the outdoor unit until the system is fully commissioned. Operating the
outdoor unit with the refrigerant circuit incomplete could cause damage to the unit.
When the door curtain has been installed or relocated, please ensure that the refrigerant circuit is pressure
tested and evacuated in accordance with Toshiba installation instructions and F-Gas Regulations. Failure to
adhere to correct installation practice could lead to a system malfunction, inefficient operation and a
breach of F-Gas Regulations relating to HFC refrigerants.
Ensure that Oxygen Free Nitrogen gas is used to perform the pressure/leak test.

Electrical Installation
ALWAYS
Ensure that the installer is suitably trained or qualified to carry out the electrical installation and that they
have the appropriate personal protective equipment (PPE) and mechanical lifting aids available to allow for
a safe installation. Only a qualified installer or qualified service person is allowed to carry out the electrical
work on this equipment. Under no circumstances must this work be done by an unqualified individual since
failure to carry out the work properly may result in electric shocks and /or electrical leaks.
When connecting electrical wires, repairing the electrical parts or undertaking other electrical jobs, wear
gloves to provide protection for electricians and from heat, insulation shoes and clothing to provide
protection from electric shocks. Failure to wear PPE may result in electric shocks.
Use wiring that meets the specification in the Installation Manual and the stipulations in the local
regulations and laws. Use of wiring that does not meet the specification may give rise to electric shocks,
electrical leakage, smoking and/or a fire.
Ensure you have read and understood the wiring diagram supplied with the unit.
Ensure that a suitable fused isolated and earthed power supply is available at a maximum distance of 1.9m
from the service level of the unit. (not Supplied)
Check that all the components referred to in the wiring diagram are present.
Use a suitable cable entry point or drill hole in the case using a hole saw sized to suit the cable gland being
careful not to drop swarf inside unit or damage internal components. Any damage to an internal
component during installation may void warranty.
Ensure an isolator switch and circuit breaker (not supplied) that meets the specifications in the installation
manual and the stipulation in the local regulations and laws must be installed between unit and power
supply.
Ensure that the unit is connected to earth (Grounding work). Incomplete grounding causes an electric
shock.
Check that after installation, repair or relocation that the ground wires are connected properly.
Make sure ALL connections are tight and free from damage.
