10 Power supply
WARNING
Switch off the machine, disconnect the electrical power cable and wait 5 minutes
before you dismantle the machine or install additional components.
ELECTRICAL HAZARD
Switch off the electrical power supply before installing electrical equipment.
The machine must be earthed (grounded).
Make sure that the actual electrical power supply voltage corresponds to the
voltage stated on the type plate of the machine.
Incorrect voltage can damage the electrical circuit.

Power socket
The electrical power supply socket must be easy to access. The electrical power supply socket
must be located at a height ranging from 0.6 m to 1.9 m (2½” to 6’) above floor level. Not higher
than 1.7 m (5’ 6”) is recommended.
Note
The equipment is shipped with 2 types of electrical power cables. If the plug
supplied on these cables is not approved in your country, the plug must be
replaced with an approved plug.
Single-phase supply
The 2-pin plug (European Schuko) is for use on single-phase
electrical power connections.
The leads must be connected as follows:
Yellow/Green Earth (ground)
Black/Brown Line (live)
Blue Neutral

The 3-pin plug (North American NEMA) is for use on 2-phase
electrical power connections.
The leads must be connected as follows:
Green Earth (ground)
Black Line (live)
White Line (live)
Residual Current Circuit Breaker (RCCB)
Note
Local standards can override the recommendations for the main electrical power
supply cable.Always contact a qualified electrician to verify which option is suitable
for the local installation setup.
Residual Current Circuit Breaker
(RCCB)
Type A, 30 mA (or better) is recommended
Power the machine
ELECTRICAL HAZARD
Switch off the electrical power supply before installing electrical equipment.
The machine must be earthed (grounded).
Make sure that the actual electrical power supply voltage corresponds to the voltage
stated on the type plate of the machine.
Make sure that the fuse is set to the correct voltage setting.
Incorrect voltage can damage the electrical circuit.
1. Connect the electrical power cable to the machine (IEC
320 connector).
2. Connect the other end of the cable to the electrical power
supply socket.
Note
In countries with a 100 - 120V electrical power supply, you must change the setting
of the equipment.
– 115V: 100-120 V/50/60 Hz
– 230 V: 200-240 V/50/60 Hz (factory setting)

How to change the voltage
1. Use a small, flat-tip screwdriver to open the cover of the fuse compartment at the back of the
control unit.
2. Take the fuse out of the fuse compartment.
3. Turn the fuse into the required position.
4. Push it back into the fuse compartment.
5. Close the cover of the fuse compartment.
11 Water supply
CAUTION
Make sure that the water connections are correctly mounted and without leaks.
Note
New water pipe installations:
Leave the water to run for a few minutes to flush any debris from the pipe before
connecting the machine to the water supply.
Hint
The machine can be connected to the same water supply as e.g. Tegramin by
using the Y-connector supplied.
11 Water supply
Lavamin 11

Technical specifications
Water pressure 1-9.9 bar (14.5-143 psi)
Water supply capacity min. 6 L/min (1.6 gpm)
Water consumption approximately 4.2-4.5 L (1 gal) per cycle (all cleaning
programs)
Mount the 90° end of the inlet hose onto the water inlet on the back of the machine:
1. Insert the filter gasket in the coupling nut with the flat side against the pressure hose.
2. Tighten the coupling nut completely.
Water inlet
• Mount the straight end of the inlet hose on the water supply tap for cold water.
• If required, mount the reduction piece with gasket on the water supply tap and tighten the
coupling nut completely.
Water outlet - drain
CAUTION
Make sure that the water connections are correctly mounted and without leaks.
1. Mount the outlet hose onto the water outlet pipe. (Lubricate with grease or soap to facilitate
insertion.) Use a hose clamp for fastening.
2. Lead the other end of the drain hose to the water outlet. Shorten the hose, if necessary.
Note
Make sure that the waste water hose slopes downwards towards the waste water
drain throughout its length.
12 Compressed air supply
Compressed air specifications
Pressure 4.5-7 bar (65-101 psi)
Air consumption, approx. 200 L/min (53 gpm)
Air quality Class-3, as specified in ISO 8573-1
To connect compressed air
1. Mount the quick coupling on the compressed air hose and secure it with the hose clamp
supplied.
