RotoPol-11/-15
Instruction Manual
A Recirculation Cooling Unit (TRECI) can be connected by means
of a Recirculation Cooling Unit Connector (ROPRE).
Connect the cable from the pump in TRECI to ROPRE,
according to the diagram of ROPRE.
Connect the cable with plug from ROPRE to the socket marked
Recirculation on the back of RotoPol.
Connect the cable from ROPRE to the mains.
Check that the pump rotates in the direction indicated on the
pump. If the direction is incorrect, switch two of the phases in
the connection to the pump in TRECI (3-phase versions only).
Replace the outlet tube on the pump in TRECI with the non-
return valve with elbow and hexagon nipple from ROPRE.
Struers recommends that you seal the threads.
Connect the pressure hose of RotoPol to the hexagon nipple.
Remember to mount the gasket.
Select the reduction piece from ROPRE which fits the drain
hose of RotoPol. Mount the piece on the outlet angle of the
TRECI.
Shorten the drain hose if necessary. Fix the drain hose on the
reduction piece: strip away a short length of the steel
reinforcement in the drain hose and mount a hose clamp on the
stripped end.
Mount the outlet angle on TRECI.
Avoid sharp bends in the drain hose and make sure that the hose slopes
If a Recirculation Cooling Unit is connected, special precautions must be
taken when working with Oxide Polishing Suspensions:
- the water coming from the built-in water tap cannot be used to wash the
oxide polishing suspension away. Use clean water.
- The outflow must not be conducted to the Recirculation Cooling Unit.
Direct the outlet to the drain or collect the outflow in a separate container.
- When working with Multidoser and Oxide Polishing Suspensions, clean
water is used automatically for flushing. Make sure that the outflow is
directed to a separate container or to the drain.
REMEMBER
throughout its length.
