HM2500 POLYTHENE HEAT SEALER
OPERATING INSTRUCTIONS
General
Before connecting the machine to the electricity supply, check the operating
voltage on the name plate attached to the base of the machine.
The wires in the mains lead are coloured in accordance with the following
code:-
Green & Yellow - Earth
Blue - Neutral
Brown - Live
Ensure that the machine is correctly earthed and connected to the mains
supply with a 5 amp fused plug.
The heating element operates at a reduced safety voltage and the machine
has its own 3.15 amp internal fuse, accessible at the rear of the body.
Operating Instructions
Switch on the machine using the amber on/off switch on the side of the
machine. Check that the switch lights up to indicate that the machine is
powered.
The HM2500 impulse sealer is fitted with a single electronic timer controlling
the heating cycle. When sufficient pressure is applied to the pressure bar, the
audible 'click' of the microswitch and the illumination of the red LED indicator
light will confirm that the machine is correctly adjusted and that power is being
applied to heat up the element.
The heating time is variable between 0 and 3.5 seconds using the external
control knob. The power is then automatically switched off even though the
pressure should be maintained on the pressure bar for 2-5 seconds to allow
the polythene to cool and regain its strength.
If the pressure bar is released before the LED light goes out, insufficient
cooling can result in premature wear of the Teflon barrier tape and other
consumable spares.
To extend the service life of the consumable items, always operate at the
minimum setting consistent with good seals and allow adequate cooling time
before removal of the bag.
