Suction line
Attention! The suction line must be installed in such a way that it does not exert any
mechanical force or tension on the pump.
Attention! In case of dirty media to be pumped, you must use a suction filter to
protect the pump from taking in sand and dirt.
Note: A non-return valve is recommended to prevent the water from running out when
the pump is turned off.
• The diameter of the suction line, regardless of whether hose or pipe, should be at least
1 inch. In case of a suction height in excess of 5 m, we recommend 1 1/4 inch.
• Install the suction valve (foot-actuated valve) with the suction basket on the suction
line. If this is not possible, a non-return valve must be installed in the suction line.
• The suction line must be installed at an incline from the water removal point to
the pump. Avoid installing the suction line above the height of the pump under all
circumstances. Air bubbles in the suction line delay and/or prevent the suction process.
• Suction and pressure lines must be installed in such a way that they do not exert any
mechanical pressure on the pump.
• The suction valve should be sufficiently submerged in water in order to prevent the
pump from running dry once the water level drops.
• An untight suction line prevents sucking in water by sucking in air instead.
• Prevent sucking in foreign objects (sand, etc.). If necessary, install a pre-filter.
Pressure line connection
Attention! The pressure line must be installed in such a way that it does not exert any
mechanical force or tension on the pump.
• All screw connections should be sealed with thread sealing tape in order to prevent
water leaks.
• All parts of the pressure line must be installed pressure-proof and properly.
Attention! Parts that are not pressure-proof and improper installation may cause
the pressure line to burst in operation! Liquids that shoot out at high pressure may
injure you severely!
Commissioning
• Place the domestic water machine on a level and horizontal spot.
• To avoid vibrations, the device should not be screwed down but placed on an elastic
mat.
• The installation site should be well aired and protected from weather influences. When
using the device in/on garden ponds, the device must be protected from flooding and
falling into the pond. Additional statutory demands must be considered.
