CAUTION!
•
Chemical could spray out. This may lead to caustic or other burns. Always relieve
the system/pump pressure before starting work on the dosing pump.
•
Before working on the dosing head, check valves and connections, flush the pump’s
wetted end with a harmless medium (mainly water) to avoid unintentional contact
with the metered medium.
WARNING!
•
Never look into the open end of a clogged line or valve.
Chemical may emerge unexpectedly and cause caustic or other burns to face and
hands.
•
Before start up, all connections must be inspected for correct tightness and, if
necessary, must be further tightened using appropriate tools.
CAUTION!
•
If connections at the dosing head are loosened during operation for venting or
other reasons, leaking chemical must be removed professionally. This is the only
way to avoid the danger of physical injury and corrosion at the dosing pump.
Leaking chemical may also damage the diaphragm at its mounting points.
NOTICE!
•
When changing the chemical, check whether the pump’s and the system’s materials
of construction are chemically resistant. If there is the danger of a chemical reaction
between different media, a thorough cleaning first is mandatory.
IMPORTANT!
•
After adjusting the stroke length, the locking screw must be retightened. Otherwise
the adjusting knob may change its position. Thus causing faulty flow rates.
DANGER!
•
Fire hazard. Pressure surge: parts may be catapulted off and cause fatal injury.
MAGDOS LC must never be used in an explosion-proof area.
CAUTION!
•
Hot metal parts may burn your hands. Always disconnect the mains power feeder
before opening the magnetic drive and let the dosing pump cool for at least one
hour.
