All cooling coils have fully boxed and insulated cases, with moisture eliminators fitted as
standard. The drain pan will require trapping to the drain line, for further information please
see VES Ref. ID665. DX and Condenser Coils must be connected to systems in accordance with
accepted refrigeration codes of practice and if fitted upstream to steam or water coils, care
must be taken to ensure that the air temperature does not drop below 0°C.
For units supplied with condensing units, refer to the appropriate supporting documentation.

Typical Twin Extract
Fan Arrangement
Fig.
For specific applications that require constant ventilation a twin extract option is available.
To ensure correct operation it is important that the unit is mounted level and that the
backdraught shutters move freely and are not obstructed by cabling or nearby components
which may have moved in transit.
The backdraught shutters require some pressure to function correctly; in this application it is
not recommended to run the extract fans below half speed (5 V).
