RAINWATER HARVESTING KITS - INSTALLATION MANUAL The timer only operates when the panel is turned on. Maintenance The <strong>Marley</strong> rainwater harvesting system is designed for minimal maintenance, requiring only periodic cleaning of the silt trap and the filter unit within the central riser. The USW200 is also fitted with an in-line filter. The cleaning frequency required to maintain efficient operation of the system will be dependent on specific installation factors such as type of roof material used for the <strong>co</strong>llecting surfaces and the proximity of any trees, but generally it is re<strong>co</strong>mmended that the inspection <strong>co</strong>vers are lifted every 4-6 weeks to carry out visual checks. a) Silt Trap Remove the inspection <strong>co</strong>ver screws and remove any large particles of debris from the trap. If required, the leaf guard can be pulled clear of the unit to check for build up of debris around the outlet. Ensure the guard is replaced over the outlet afterwards. If the level of <strong>co</strong>llected sediment is within approximately 100mm of the invert of the outlet, use a small <strong>co</strong>ntainer to remove it before replacing and securing the <strong>co</strong>ver b) Water Filter Both systems in<strong>co</strong>rporate a 30 day reminder timer within the <strong>co</strong>ntrols to advise when the filter needs to be checked. This can be reset by pressing the right hand button. The frequency with which the filter needs to be checked and cleaned will depend on the specific installation <strong>co</strong>nditions and, to a certain extent, the time of year. To access the water filter unit, unscrew and remove the inspection <strong>co</strong>ver from the inlet chamber. (Refer to ‘Operational safety’ on back page). i.Reach down into the chamber and pull the flexible hose elbow from the top of the filter housing, taking care to ensure that any <strong>co</strong>llected debris in the hose does not fall into the water ii.Release the filter housing outlet from its <strong>co</strong>nnection by pulling the housing upwards then withdrawing it with the outlet uppermost. iii.Remove the filter housing <strong>co</strong>ver by unscrewing the two screw fixings and flush out any <strong>co</strong>llected debris from the filter drum with a hose. If there is any fine sediment in the base of the housing the drum can be removed by releasing the base screw. iv.If the drum is removed, ensure that the fixing bar is aligned with the centreline of the outlet when it is replaced. When replacing the filter unit ensure that the outlet is <strong>co</strong>rrectly located in the inlet chamber and that the two support legs are firmly seated across the well. c) In-line filter Before <strong>co</strong>mmencing, ensure that the power supply to the <strong>co</strong>ntrols is isolated and that the isolation valve is closed. To clean the filter mesh, loosen the nut on the body, unscrew the housing, remove the filter and flush under a tap. Operational safety Although it is inevitable that <strong>co</strong>llected rainwater in the storage tank will <strong>co</strong>ntain a small amount of bacterial matter, under normal circumstances this will not present a problem. It is however advisable to observe the following precautions when using the system. •Do not allow excessive amounts of debris to build up in the silt trap and main filter. Even if the system appears to be functioning, the maintenance checks detailed in this manual should always be carried out on a regular basis. •Do not allow the water to be used for drinking purposes. •Always dis<strong>co</strong>nnect and drain down any garden hoses <strong>co</strong>nnected to the system after use. Wherever possible, store hoses away from any heat sources such as direct sunlight. •In normal use the inspection <strong>co</strong>ver to the well must be kept secured with the three fixing screws fully tightened. Access should only be required when carrying out periodic maintenance on the filter unit. •Whenever the <strong>co</strong>ver is removed for inspection or filter cleaning, the well must not be left unattended. In particular, children should be kept away from the area. •Always isolate the power supply when carrying out any maintenance work on the system. •If the mains supply cable be<strong>co</strong>mes damaged during use it must be replaced by a qualified electrician. •If the supply cable to the pump be<strong>co</strong>mes damaged during use, the pump must be replaced.
