INSTALLATION
Electrical consumption
When installing a B4 NS melter, the installation’s total consumption must be
taken into account, including the consumption of the installed hose and
applicator.
Before connecting the melter, make sure that the voltage to which it is to be
connected is the same as that indicated on the equipment’s nameplate.
Connect the melter and check that it is well grounded.
Warning: Risk of electrocution. Even when the melter is turned off, voltage
remains in the input terminals, which could be dangerous when the
equipment is handled internally.
The B4 NS melter should be installed with a power switch to disconnect it
from its power supply source. A circuit breaker should be installed as personal
protection against earth leakages.
The powers associated with these protections are indicated in the table in
section ‘Electrical power supply connection’.
Compressed air
The installation of melters from the B4 NS series requires a non-lubricated
compressed air dryer system with a maximum pressure of 6 bar to supply the
pusher disk cylinder and the pneumatic bypass valve in case of the melter has
one.
Other factors
Other practical considerations should be taken into account when installing
the B4 NS melter:
• Make sure the cylindrical hopper remains accessible to facilitate
changing the adhesive block.
• Position the melter so that it is easy to see the front panel display
where the temperatures and possible alarm signals are shown.
• As far as possible, try to avoid unnecessarily long hoses which
consume a lot of electrical energy and result in high pressure drops.
• Do not install the melter next to powerful heat or cooling sources
which may affect its operation.
• Avoid melter vibrations.
• Make sure that the melter maintenance areas (pump, purging valve,
cylindrical hopper, gear motor, etc.) are easily accessible.
