WARNING: Do not pump petrol or fluids
with a flash point below 100°F (37.8°C).
Doing so may result in explosion which
could cause personal injury, death or property damage.
Installation Instructions
• The Cyclone can be mounted on any flat surface.
• The pump must be installed below the lowest fluid level to
maintain flooded suction.
• Fit pump in a dry, well ventilated position.
• Use rubber grommets provided to minimise vibration.
• If mounted vertically, ensure the motor is above the pump
head.
• Use 3/4" pipe fittings with PTFE pipe joint tape or compound.
• Plastic fittings should not be used if pump is installed below
the waterline.
WARNING: All marine pumps discharging
overboard must be installed with the overboard
discharge well above both static and heeled
31.7 (120)
waterlines. Flooding and death may occur.
Maintenance
• Check all electrical connections periodically.
• Check seal area for signs of leaking.
