Precautions
This guide should be read and utilised in conjunction with the official published regulations and
!
codes of practice, be they local, national or international.
Each air conditioning system will have its own discrete power supply, with overload current
!
protection.
!
The current protective device will prevent and protect the supply cable against overcurrent.
The cable should be selected to match the nominal load of the system, in addition to the losses
!
associated with corrections for length, temperature, impedance, etc. In accordance with local
codes of practice.
GB
!
Install a multi-pole isolation switch (with 3mm separation) in the power supply circuit.
Earth both the indoor and the outdoor units by attaching an Earth wire. Ensure this is carried out
!
according to National Wiring Regulations.
Wiring for the power supply must be performed by a qualified electrical engineer or technician
!
only.
Do not allow the cables (used for the power supply and for wiring between the units) to come into
!
contact with valves or pipes not covered with insulators. Secure these cables to the parts of the
pipes with heat insulation fitted.
Use the Ø20mm knockouts provided on the units to fit cable glands to hold the cables securely at
!
the point where they enter the electrical box or unit.
