Intended use
The hotplate can be used for heating up non-explosive substances and
objects.
Attention: When using flammable substances safety precautions need to
be taken into account, e.g working in a fume cupboard. Liquids must not
be poured directly onto heating surface!
Use the device in indoor environments similar to that of a laboratory of
research, teaching, industry or trade.
1. Installation of models A and SR
All four feets of the appliances are height-adjustable by rotation to 8 mm
and enable a stable horizontal installation.
Due to the extremely high temperature of 500°C the radiating temperature
is accordingly intense. Therefore never install the hotplates near
combustible walls made of timber, plexiglass, plastic etc. even if only low
and medium-high temperatures are employed. lt must be assumed that
the highest temperature can be set, and that the unit can be left on
overnight due to forgetfulness and not switching-off. A possible failure of
the automatic control must also be taken into consideration.
The distance from walls sensitive to heat or combustible must amount to a
minimum of 15 cm. lf this is not possible due to restrictions of space, a
corresponding insulation is necessary. For example, a high-grade steel
sheet between the heating plate and the wall arranged with a clearance to
each other, absorbs approx. 50 to 90% of the laterally radiated heat. At
the same time such a vertically positioned sheet would also serve as a
splashing protection on the occasion of a possible container fracture.
The manufacturer and retailer assume no liability of any kind for possible
arising damage to property.
Do the following test yourself: Set the control to the maximum temperature
and heat for at least 1 hour. Then convince yourself of the great ambient
temperature. This intense heating also has the further advantage of
rapidly freeing the unit from the arising smell and fume formation, typical
for new appliances.
2. Electrical connection
The 230 Volt unit is ready for connection. Only earthed connectors with
protective contact are permissible. The 400 Volt unit has a 5-pole cable,
whereby wire colours are yellow/green basically the protective conductor,
and blue basically the wire for the neutral conductor. The neutral
conductor is needed for the control voltage of the electronic (230 V). The
remaining three cores can be connected arbitrarily to the 400 V network,
as in contrast to, e.g. motors, no determined polarity is necessary.
Electrical connection must be only carried out by an electrically qualified
person.
