3.2 Installation
Place the Wax Dispenser on a flat and stable surface, preferably away
from drafts. Plug the power cord into a voltage source that matches the
voltage listed on the serial number label on the rear of the unit. Insure
that the surface on which the unit is placed will withstand the radiated
heat produced by typical laboratory equipment.
4. Operation
4.1 Controls and Indicator Lamp (see Figure 1)
1. Power Switch - Controls power to the unit.
2. Heater Control Dial – Used to set desired temperature.
3. Power on Lamp – When illuminated indicates unit is powered up.
4. Heater Indicator – When illuminated indicates heater is on.
5. Dispenser Valve –Used to dispense wax. The valve can be used to
dispense wax on demand, or rotate the handle 180° to lock the handle
into a constant flow position (See Figure 2).

FIGURE 2
Caution: Assure the reservoir is filled with a minimum of 2.5 cm of wax and
a maximum of 2.5 cm below the top of the reservoir and the dispenser
valve is positioned for “On Demand” dispensing before applying power.
Use caution when filling the reservoir with wax to avoid overfilling the
unit.

4.2 Setting the Temperature
1. When setting the temperature to melt the Paraffin Wax, refer to
Paraffin Wax manufacturers recommended melting temperature prior
to adjusting the heater control knob. Generally, it will take
approximately 2 hours to fully melt a reservoir full of Paraffin pellets.
2. Adjust the heater control dial to desired temperature.
3. The Heater Indicator Lamp will illuminate to indicate that the unit is
heating up. When the set temperature is reached the heater indicator
lamp will cycle on and off to maintain the set temperature.
