Valko FAVOLA 315/06 Instructions For Installation, Use And Maintenance Manual page 15

INSTALLATION
Installation, assembly and troubleshooting must only be performed by skilled personnel strictly in accordance
with the following instructions :
- Remove the machine from the packing and throw away the protection pieces.
- Remove the protection film from the equipment and the strap from the cover.
- Keep a minimum distance of 10 cm. all around the machine in order to allow adequate
cooling of the pump during running (the machine could have difficulties to reach the desired
vacuum).
- Set the machine perfectly straight by adjusting the supporting feet until the correct position
has been reached. A wrong alignment of the machine could affect the performance during
running.
- For the installation of the machine an omnipolar switch must be mounted between the power
network and the equipment and it must have a minimum contact distance of at least 3mm
per pole. Allow easy access to the switch.
- The rating plate is on the rear of the machine. From the plate can be checked if the
equipment is set to run with the available line voltage. Check that the available power
voltage matches the one printed on the rating plate.
- During running of the machine the voltage must be within +/- 10% of the correct rating.
- Earthing the equipment is mandatory in order to avoid damaging the electronic board.
- It is strictly mandatory to comply with the fire regulations!
DIRECTIONS
ATTENTION : To avoid spilling oil from the pump which could damage the equipment never turn the machine
upside down or incline it.
THE EQUIPMENT MUST BE PLACED IN A WORKING ENVIRONMENT WITH AN AMBIENT
TEMPERATURE NOT LESS THAN 12°C.
For machines preset with Inert gas injections : the maximum pression of the gas entry must not be more than
3 bar, in order to avoid that the Inert gas valve brakes.
LEGAL REGULATIONS, TECHNICAL RULES AND DIRECTIVES
During the installation the following rules and regulations must to be observed :
- Legal regulations in force (to be defined Country by Country)
- Accident protection requirements and laws in force (to be defined Country by Country).
ELECTRICAL CONNECTION
See enclosed wiring diagrams.
Check the power supply and voltage with the rating on the plate. The machine is supplied with cable and
plug.
REPLACING OF THE CONNECTING CABLE
In case of cable replacement check the electrical scheme.
The replaced cable must not be less than type H05 RN-F in quality and shall have a minimum wire section
2
of 3x1,5 mm .
During connection carefully make sure that the earth wire is longer than the others. In case of an unexpected
strong pull on the cable or in case the cable clamp breaks the earth wire must be the last to disconnect from
power.
The machine can only be started after having checked that all these safety precautions have been carefully
observed.
