Hydrotech C, C PLUS, A PLUS, E, E-DC and E PLUS Series PULSAtron - Manual (Page 4)

Please read all these cautionary notes prior to installation and start-up of your
metering pump.
Important: Pump must be installed and used with supplied back pressure/injection
valve. Failure to do so could result in excessive pump output.
• Handle the pump with care. Dropping or heavy impact causes not only external
damage to the pump, but also to electrical parts inside.
• Install the pump in a place where the ambient temperature does not exceed 104
°F
(40
°C). The pump is water resistant and dust proof by construction and can be
use outdoors, however do not operate the pump submerged. To avoid high
internal pump temperatures, do not operate in direct sunlight.
Solenoid housing, head and pump housing may be hot to touch
160
o F (70 o C).
• Install the pump in a place convenient for its future maintenance and inspection,
and then secure it to prevent vibration.
• Protective caps must be removed prior to installing tubing onto valve assemblies.
Use tubing of specified size. Connect the tubing to the suction side securely to
prevent the entrance of outside air. Make sure that there is no liquid leakage on
the discharge side.
• Be careful to check that the voltage of the installation matches voltage indicated
on the pump data label. Most pump models are equipped with a three-prong plug.
Always be sure the pump is grounded. To disconnect, do not pull wire but grip
the plug with fingers and pull out. Do not use the receptacle in common with heavy
electrical equipment, which generates surge voltage. It can cause failure of the
electronic circuit inside the pump.
• Tampering with electrical devices can be potentially hazardous. Always place
chemicals and pump installation well out of the reach of children.
• Never repair or move the metering pump while operating. Always disconnect
electrical power. For safety, always wear protective clothing (protective gloves
and safety glasses) when working on or near chemical metering pumps.
• An air bleed valve is available for most models with tubing connections. Air
purges should be performed when the pump-chamber contains no fluid at the time
of start-up. As a safety measure, connect the return tubing to the air bleed valve
and bypass fluid back to storage tank or a suitable drain.
• For accurate volume output, the pump must be calibrated under typical operating
conditions.
