Installation
3. Supply Tubing
The supply tubing run should be as short as possible. For flooded suction mounting, install a shout-off
valve with an appropriate tubing connector at the tank outlet. Cut a length of tubing from the coil supplied
and install between the shut-off valve and the pump inlet fitting. For suction lift applications, install a foot
valve on one end of suction tubing and cut the tubing to a length such that the foot valve hangs vertically
about 25mm above the bottom of the tank. Avoid any loops in the tubing run that could form a vapour trap.
Running the tubing through a length of PVC pipe will help to keep tubing straight.
4. Discharge Tubing
The discharge tubing run is less critical and can be any length required to reach the application point. Avoid
sharp bends or kinks in the tubing and protect the tubing from sharp edges that could chafe or cut it. Install a
check valve (optionally available) at the injection point and connect the discharge tubing to the check valve.
CAUTION
Any check valve using Hastelloy or other metal springs in liquid end is not usable for
chemicals (such as HCL) which corrode the Hastelloy or other metal springs. Ask IWAKI
for a special check valve for this application.
5. Electrical
Connect the pump power cord to a GROUNDED outlet supplying proper voltage. Avoid branch circuits that
also supply power to heavy machinery or other equipment that could generate electrical interference.
Be sure to equip the power cord with a noise filter. The DENSEI-LAMBDA MBS1205-22 is recommended.
Refer to manufacturer's instruction for the noise filter before use.
