3-1Caravan Service Systems 33.1 THE WATER SYSTEM3.1.1 Priming the System using the External Water Container1. Adjust dust cover over water containeropening (please note dust cover shouldnot be secured to water container asair must be allowed to enter containerto replace water being drawn out).2. Open one cold tap (e.g. kitchen sink).3. Place carbon filter assembled to hose,into a full water container.4. Insert plug into wall socket and closelid to lock plug in place (see fig. 1).5. Switch on 12 volt supply at main controlpanel located by the exterior door.6. Water will flow from the open tapexpelling any trapped air in a fewseconds. The water may at first begreyish in colour which is quite normal,the discolouration is due to harmlessmedia being flushed out of the newfilter cartridge.7. Close cold tap and open hot tap toexpel any remaining air in the waterheater (this may take up to 30seconds). Then repeat this exercisewith the remaining taps in the caravan.8. The system is now ready for use. Hose can be inserted into plug groove (fig. 2) to keep filter off theground while refilling water container. Keep socket lid shut at all times when plug is removed.9. When the caravan is left unattended or water supply has been allowed to empty to prevent thepump running continuously, turn off at isolating switch.10.
