Refco YUMA Guía De Instalación Y Funcionamiento página 4

Operation
The YUMA contains an internal sensor that will automatically start the pump when
condensate is detected and stop the pump when the condensate has been removed.
The YUMA is also fitted with a high water level alarm that will operate the alarm relay if
the water level rises to abnormal levels. The pump will continue to run until the minimum
water level is reached and the alarm will reset.
Installation
The YUMA pump can be installed at any angle between horizontal and vertical so long as
the breather tube inlet is above the condensate inlet (Fig. 3). The YUMA can also be tilted
sideways up to 30° from horizontal (Fig. 2).

The YUMA pump should be positioned in a suitable location within the equipment below
the level of the collection tray. The top of the breather tube should be positioned above
the highest part of the collection tray to avoid overflowing (Fig. 4). The YUMA pump,
condensate tubes and mains cable should be kept away from panels and surfaces and,
where possible, insulated with foam to minimise noise.
