Precautions on Setup
DANGER
・Use the same pipe type and size for the hose and nozzle to be connected. When connecting, be
sure to check the packings and connect accurately.
If the pipe size or type is inadequate, the packing is lost or damaged, or the threads is loose, you
may be exposed to the chemical. Also, you may be exposed to the chemical because the packing
comes out or is damaged if the fittings are over-tightened. Tighten the screw adequately.
・Before preparing the conditioner, be sure to check for leaks with fresh water.
(Water intake)
・The standard suction tube diameter is the diameter of the pump suction port. If the suction hose
has elbows or valves, etc., use one-pipe size larger suction tube diameter.
CAUTION
If the suction tube diameter is smaller than required, performance degradation or failures may be
caused.
・Suction pump head must be 3 meters or less.
(Spraying)
・Select spraying hose rated at or above the pump pressure.
(Hose)
・Put the suction hose and bypass hose in the tank accurately and fasten them with clamps, etc.
securely.
・When connecting the hose, be sure to check any seals and threads for tightness.
WARNING
Connect the bypass hose only to the bypass port. If the bypass port is fully closed by connecting a
valve, the machine may be damaged and personal injury may occur. Therefore, never connect a
valve to the bypass port or hose.
(Nozzle)
・Select a nozzle that flows approximately 30% of the bypass volume.
DANGER
・If proper nozzles (proper to performance of the pump), the standard fittings are removed, or the
nozzle is handled unreasonably, the original performance cannot be exercised and troubles or,
depending on the case, personal injury or damages may be caused.
CAUTION
・Do not point the nozzle toward people because exposure to the chemical may occur.
