Electrics installation
The electrical installation, which the machine is connected to, must be carried out by a skilled
electrician according to regulations and observing the Laws in force. An efficient electrical
installation with earthing is the most important thing in order for your machine to work
perfectly.
Fit a suitable wall switch: we strongly recommend fitting an automatic differential switch. See table
(A) for power rating and absorption details.
Check taht the mains voltage rate is the same as the machine rating, shown on the serial number plate
(see page 5).
The power cable has 4 wires: the yellow/green wire is the earth wire, the other three are for the three
phases.

Water connection
The refrigeration system has a water-cooled condenser. A connection for the hot or cold water pipe
exists. It is useful for washing the machine. Its tap and nozzle are in the front of the machine.
Connect the mains hose to the fitting that reads " ENTRATA ACQUA- WATER INLET ".
The drain hose must be connected to the fitting that reads " USCITA ACQUA-WATER OUTLET ".
The connection plates and fittings are inside the machine: to access these, remove the rear panel.
To connect the machine to the mains, we recommend using a rubber hose suitable for up to 10 bars
with an inside diameter of about 15 mm (matching the fittings supplied with the machine).
If, for any reason, the plates indicating water inlet and outlet are illegible, please note that the water
inlet hose is fitted to the pressure-switch valve.
WATER PRESSURE AND CONSUMPTION
If the machine is using mains water, check that the incoming water has a pressure of at least 1 bar.
If the water pressure is more than 5 bar, fit a pressure reducer to the system, to reduce this to 4 bar.
Average water consumption (when the refrigerating unit is on) is:
- MANTEGEL 20 = 80/100 litres/hours*
- MANTEGEL 30 = 100/190 litres/hour*
- MANTEGEL 50 = 150/250 litres/hours*
- MANTEGEL 70 = 300/450 litres/hours*
* depending on the temperature of the incoming water.
If the water contains impurities, fit a purifying filter to avoid scaling and/or damage to the
pressure-switch valve.

TECHNOGEL spa CANNOT BE HELD RESPONSIBLE FOR ANY DAMAGE CAUSED BY
INCORRECT POSITIONING OF THE MACHINE IN AN UNSUITABLE PLACE. THE
COMPANY IS ALSO UNABLE TO ASSUME ANY RESPONSIBILITY FOR INADEQUATE
PERFORMANCE OF THE MACHINE OWING TO OPERATING CONDITIONS BEING
BEYOND THE LIMITS OF ACCEPTABILITY.
Positioning of machine with fixed air condenser
VALID FOR MACHINES WITH EITHER AIR CONDENSATION OR AIR/WATER COMBINED
It is extremely important that the machine should be installed in a spacious room with doors
and windows so the air heated by the machine can be changed regularly.
The rear of the machine must be place at a distance of at least 0.5 metres from the wall.
During operation of the machine, the doors and windows in the room must be left open
otherwise the air heated by the machine will become extremely hot and could reach
temperatures of around 50°C. If the machine is allowed to operate in these conditions the
main components (refrigerator compressor and turbine motor) could well overheat over the
long term and this could jeopardize correct operation of the machine and cause damage which
would be costly to repair. It would also mean an increase in running costs owing to the high
consumption of electricity w hile the machine’ s performance w ould be reduced by 50% .
IDEAL POSITIONING OF THE MACHINE
As shown in the diagram, the air coming in through the door (1) is sucked in and heated
during condensation of the ventilators (2) and is pushed in the direction of the window (3)
and thus outside.
The ideal solution, though not always easy to put into practice, is to make holes in the wall
(4) opposite the ventilators (2). The air can therefore flow out freely without any problem and
the machine’ s performance w ill alw ays be excellent.

Positioning of the machine with remote air condenser
In order to combat problems of overheating of the air, whenever possible the remote air condenser
should be mounted.
CAUTION:
Copper or flexible piping (T) transporting the refrigerant gas from the machine to the condenser and
vice versa,
Should not exceed 4 metres in length.
The condenser must be fixed to wall brackets positioned high up so that they are beyond the reach of
people of average height.
As illustrated in the diagram, the condenser must be positioned at least 200 mm from the wall so that
air can be sucked in without any problem. It is also advisable to install protective roofing over the
equipment to protect it from rain water.
with remote air condenser
The machine must be installed by a Refrigeration Technician who after connecting the equipment will
check that the quantity of gas inside the machine is correct for optimum operation.

After positioning the machine and locking the front wheels by pressing on the brake with the feet (do
not use the hands for this operation), check that the feet (P) both rest on the floor. If the feet (P) are
not level, during operation the condenser could move around owing to movement of the ventilators.
If the machine operates in contact with other machines, make sure there is a space of at least 25
cm between them.
Carry out the electrical connections of the machine and make sure that the electric cable (E) comes
from above and is not laid on the floor where it could be crushed. For data on power and
absorption please see page 22 Table A under the specific machine reference.
For the MANTEGEL 30 and MANTEGEL 50 machines, it is possible to connect hot or cold water
for washing purposes to the rear of the machine.
