GENERAL INFORMATION Read this manual carefully before installing the drum lter! Keep this manual close to the drum lter so you can consult it at all times. For external components (such as cleaning pumps) the manufacturer supplies separate manuals for installation and maintenance. Read these manuals also carefully and follow the concerning instructions.
INSTALLATION The drum lter must be placed on a rm, at (level!) surface. The drum lter is suited for gravity- and pump fed applications. Default position of the level switch is for gravity application (level switch in drum chamber). For gravity application the installing height (above the water level of the pond ) is minimum 10 cm from the top of the waste gutter (see drawing).

Example gravity application Skimmer Pump Bottom drain Slidevalve Example pump-fed application For pump fed application you must change the position of the level switch from the drum chamber mounting bracket to the inlet chamber mounting bracket (see next page for detailed instructions). For pump fed application the level switch must be rotated 180 degrees (see illustration).

Level switch position change from drum chamber to inlet chamber. Default situation: level switch in the far left opening, blind plug in the middle, cover switch on the far right. Take out the spray pipe rst to have good access to the level switch.
CLEANING PROCESS Due to a change of the water level the level switch will give the controller a signal to start the cleaning process. As the water around the level switch can move as “waves”, the controller will only start this process once the level switch will stay in this position for 5 continuous seconds (to prevent an ongoing “on/o ”...
CLEANING PROCESS DURATION As it is not always desirable to stop the cleaning process as soon as the level switch has reached its normal position we o er a few possibilities here. With 4 dipswitches on the inside of the controller unit you can adjust the time increase according to these options: All dipswitches in the “OFF”...
Example: the maximum cleaning time is set to 20 seconds. If the level switch will not return to its normal position after these 20 seconds a safety procedure will be initiated. This procedure follows these steps: 1. The controller stops the motor and the cleaning pump/solenoid valve 2.
