Important Safety
Information
The pump contains internal moving parts. DO NOT put hands or
fingers into the pump body ports or drive area at any time during
operation. To avoid serious injury, DO NOT install, clean, service,
or repair the pump unless all power is off and locked out and the
pump is de-pressurized.
The pump components and piping may contain sharp edges.
Handle the impeller carefully because edges may be sharp. Wear
gloves while installing and servicing the pump to help avoid
injuries from these hazards.
Make sure to keep the work area clear of machine parts, tools,
product lines, foreign materials, and power cables to avoid
potential hazards.
Make sure appropriate lighting is available: at least 1000 lux,
independent of daylight and weather conditions.
Before carrying out any maintenance and repair work on cold
components, ensure that the machine parts in question are
sufficiently heated. The contact temperature of accessible
machine parts must not be lower than those in the EN ISO
13732-1.
Before detaching port connections to the pump:
• Close the suction and dischar
ge valves.
• Drain the pump and clean or rinse, if necessary.
• Disconnect or shut off the electrical supply and lock out all
po
wer.

Keep maintenance records. These will help pinpoint potential
problems and causes.
