General Description
The Wax Dispenser is designed for on-demand delivery of molten wax. The novel design of the instrument ensures
that it takes up a minimum bench space in the laboratory, whilst still maintaining a large 7.5L capacity tank, for
melting up to 6kg of pelletized wax at a time. The Wax Dispenser has digital temperature control which provides
accurate temperature control of the molten wax, and is coupled with an ultra fast heating system for rapid melting
of pelletized wax. Delivery of molten wax is via a non-drip lever tap, which is heated via a dedicated heating
system, which prevents blockages resulting from solidied wax and ensures an even ow of wax. The inner tank has
a lter screen (0.5mm mesh) tted to prevent coarse particles from blocking the delivery tap. The tank is also fully
insulated to prevent heat loss from the tank and to ensure that the outer surfaces of the tank are safe to touch.

Electrical Requirements
THIS INSTRUMENT MUST BE GROUNDED
Before connection please ensure that the line supply corresponds to the power requirements below:
Power: 480W Supply requirements: 110 - 120 V or 220 - 240 V ~ 50/60Hz
The unit is provided with three power cables consisting of a UK 3-pin and a “Schuko” 2-pin plug for 230 V
installations and a NEMA 5-15 plug for 120 V installations.
Choose the power cable appropriate for your electrical installation and discard the other. Should neither power cable
be suitable for connecting to the power supply, replace the plug with a suitable alternative.
THIS OPERATION SHOULD ONLY BE UNDERTAKEN BY A QUALIFIED ELECTRICIAN.
NOTE: Refer to the equipment rating plate to ensure that the plug and fusing are suitable for the voltage and
wattage stated. The wires in the mains cable are as follows:
230V 120V
BROWN - HOT/LIVE BLACK - HOT/LIVE
BLUE - NEUTRAL WHITE - NEUTRAL
GREEN/YELLOW – EARTH GREEN - EARTH
The appropriate power cable and power adaptor combination should be connected to the instrument BEFORE
connection to the mains supply. Should the mains lead require replacement, a heat resistant cable of 1.25mm²
(AWG16) of harmonised code H05VV-F connected to an IEC320 plug should be used.
IF IN DOUBT CONSULT A QUALIFIED ELECTRICIAN
THIS EQUIPMENT MUST NOT BE FLASH TESTED
