Start the sprinkler system and make sure that no
nozzle (1) is clogged. If necessary, clean clogged
nozzles and the coarse filter located adjacent to the
water pump (2); see figures below.
A pump system is located underneath each water tank
behind the cover (2), which is opened by turning the
quick-screws (3) a 1/4 turn counter-clockwise. To lock
the cover, place the screws with the slot vertical and
push straight in.
When cleaning the coarse filter (1), close the stopcock
(2) and loosen the filter housing (3).
Clean the filter and filter housing, ensure that the rubber
gasket in the filter housing is intact.
After inspection and any cleaning, start the system and
check that it works.
A drain cock (5) is located in the left part of the pump
system area. This facilitates draining of both tank and
pump system.
