Always store chemicals in safe, out of reach places. Follow the
directions for use with each chemical. Do not assume chemicals
are the same because they look alike. Hanna Instruments cannot
be held responsible for the misuse of chemicals or the pump.
Always wear protective clothing (gloves and safety glasses) when
working near chemical dosing pumps. When pumping chemicals,
make sure all tubes are securely attached to the fittings. It is rec-
ommended that tubing is shielded to prevent possible injury in
case of rupture or accidental damage.
Avoid using a pipe wrench or pliers on plastic parts and connec-
tors. These are best tightened with an open end or crescent wrench.
Avoid overtightening these parts as this could cause damage to
the seats and threads.
If a hose is used, it should be securely fastened to columns, walls,
braces, etc. This will ensure that the hose connection will remain
tight and leak free. Shield the hose from direct sunlight. Sunlight
can cause an autocatalytic reaction with some chemicals and
weaken the hose walls.
The arrow on the pump head indicates the direction of chemical
flow and should always point upwards (vertically). Never position
the pump horizontally with suction and discharge valves horizontal.
Locate the pump in an area out of the reach of children and pets.
All pumps undergo stringent tests to ensure that they comply with
their stated specifications and are calibrated at the maximum rated
pressure.
