4. Installation /
Commissioning
4.1 Setting up and Connecting
the Unit
1. Inspect the tank for proper installation (Fig. 1).
2. Check the voltage information on the nameplate.
3. The unit is operational with two tanks. To connect
additional tanks, please refer to Installation
Instructions, No. 21-9499.
4. Remove the foot switch from its shipping location
in the blasting chamber.
5. Connect the foot switch to the sandblasting unit
(red + yellow). Make sure to both pneumatic ho-
ses are fully inserted up to their stops (Fig. 2).
6. Connect the compressed air supply to the sand-
blasting unit. To do this, loosen the screw-on air
coupling on the unit (Fig. 3).
7. Push the screw-on coupling over the supplied blue
compressed air hose (Fig. 4).
8. Connect the compressed air hose to the unit and
tighten the coupling sleeve (Fig. 5a).
9. Connect the compressed air hose to the com-
pressed air supply (Fig. 5b).
4.4 Adjusting the Operating
Pressure
• The product is repaired by other than an
authorized facility or if any but Renfert OEM
parts are employed;
• The product continues to be employed,
despite obvious safety faults.
Caution: Minimum connecting pressure
5 bar [72.5 psi] !
10. Do not bend or kink the hoses (Fig. 6)!
11. Connect the dust extraction hose to the extraction
tube (Fig. 7).
Do not connect the unit to the
mains power supply yet!
4.2 Fluorescent Lamp
Installation
1. Remove the plastic sheet from both sides of the
lamp cover (Fig. 8).
2. Push the lamp cover over the fl uorescent tube
(Fig. 9).
3. Insert the tube horizontally (Fig. 10).
>>> Please observe the safety instructions
(Sec. 3)!
4.3 Starting the Unit
1. Connect the mains power cord to the sandblasting
unit (Fig. 11), then plug the power cord into the
wall outlet (Fig. 12).
2. Switch the unit on (Fig. 13).
Caution: Never activate the pressure regulator
in the maintenance unit. The regulator has been
factory-set for a pressure of 6 bar to ensure
optimum pinch valve function.
1. Select the sandblasting tank (Fig. 14).
2. Activate the foot switch (Fig. 15) and adjust a blas-
ting pressure of 1 - 6 bar (14.5 - 87 psi)
(Fig. 16). The pressure is displayed on the mano-
meter (Fig. 16a). The pressure adjustment applies
to all sandblasting tanks.
4.5 Filling the Sandblasting
Tanks
Caution: Never press the foot switch during
fi lling. Before closing the tank, be sure to
clean the threads in the cover and the tank to
remove any abrasive residue.
1. Release the pressure from the tank (Fig. 17).
a = tank under pressure, b = pressure released.
2. Unscrew the cover (Fig. 18).
3. Add abrasive up to the maximum fi ll level (the
point where the tank jacket thickens just below
the thread) (Fig. 19+20). Make sure the abrasive
being used is compatible with the sandblasting
tank.
4. Reinstall the tank cover (Fig. 21).
Caution: Do not cross-thread the cover.
Always use only clean, dry abrasive of the
appropriate grain size (refer to the accessories).
The sandblasting unit is now operational.
A slight sound or rushing air while the unit is opera-
ting is quite normal and does not indicate a fault.
5. Cleaning / Maintenance
5.1 Cleaning the Interior
• Use only solvent-free cleansers (e.g., soapy water).
• Remove the grate and vacuum the blasting
chamber (Fig. 22+23).
• Wipe out the tanks and lids only with a dry cloth!
5.2 Condensation
1. Inspect the water separator.
2. Drain any water off through the valve (Fig. 24).
5.3 Blasting Nozzle
Replacement
1. Refer to insert no. 21-9162 for installation.
2. Inspect for abrasive residue.
3. Inspect the seal ring position.
