General Information
The Lailey and Coates Split System consists of two major parts: The Internal and External
Units. They are connected via refrigeration pipes and an ELV, shielded, communication
Cable.
The external units can either be wall mounted or hard-standing but should be secured via
suitably designed mounting systems available from Lailey and Coates. When siting the
outdoor unit it is essential that an adequate, un-restricted level of airflow is available to
ensure correct operation and maximum efficiency of the system. See page 7.
The Internal Unit is designed to be wall mounted in a suitably dry position.
The Lailey and Coates Split System will accommodate all your heating and hot water
demands and is suitable for use with; under floor Heating, Radiators and Fan Coil Units.
The system is integrated with an Electrical Heater for extreme weather conditions and also
acts as a backup if there is a problem with the External Unit.
