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 solidified wax and ensures an even flow of wax. The inner tank has
a filter screen (0.5mm mesh) fitted 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

Safety Cut-outs
The equipment is protected by a miniature circuit breaker and a temperature cut out.
The miniature circuit breakers are located on the rear of the equipment. In the event of a fault, push back to
reset. If the fault continues, please contact your local service representative or the service department of Antylia
Scientific.
If the temperature cut-out is operated allow the equipment to cool completely. Identify and rectify the cause of
cut-out operation before operating. If the temperature cut-out continues to operate, please contact your local
service representative or the service department of Antylia Scientific.
Operation
Before Use
Place the unit on a firm, level surface, ensuring that all four feet on the base of the unit are positioned on the
surface firmly. Avoid installation on a slippery surface or on a surface prone to vibration.
Note: Button is not required in this application.
1. Ensure that the power cable is pushed fully into the power supply socket of the wax dispenser.
2. Connect the mains plug to the electrical supply.
3. Pour the desired quantity of wax into the internal tank. The tank has a maximum capacity of 7.5L which is
large enough to melt 6.0kg of pelletized histology wax.
4. Turn ON the wax dispenser.
5. Setthedesiredtemperature.Usersarerecommendedtosetthetemperature3-4˚Cabovethemeltingpoint
being used.
a. Press then release it (do not hold down for more than 5 seconds).
b. The display will show alternating with the current set temperature.
c. To change the set temperature press to increase the value or to decrease it. These
keys increase or decrease the value one digit at a time, but if the button is pressed for more than one
second the value increases or decreases rapidly, and after two seconds pressed, the speed increases
even more to allow the desired value to be reached rapidly.
d. Exiting the Set mode is achieved by pressing or automatically if no key is pressed for 15
seconds. After that time the display returns to the normal function mode.

6. The heater indicator will illuminate to show heater activity.
7. The equipment will warm up to the desired temperature and temperature rise will be shown on the display.
8. The wax dispenser is designed to melt bulk quantities of pelletized wax in as quick a time as possible.
When set at 65oC the instrument will take roughly 90 minutes to fully melt 5kg of pelletized wax, with
significant quantities of molten wax available for use after as little as 30 minutes.
9. Wax is delivered by pulling the tap lever forward. The tap has three positions:
i Off ii On demand pull dispense iii Continuous flow - tap locked open
CAUTION: Do not operate the tap while the wax is cold as this may damage the tap.

Maintenance, Servicing and Cleaning
WARNING:Before attempting any maintenance, servicing or cleaning, ensure that the unit is cool.
WARNING: Do not touch any electrical contacts or open any closure plates.
RISK OF ELECTRIC SHOCK.
WARNING: Ensure the unit is disconnected from the power supply before attempting any
maintenance, servicing or cleaning.
Regular cleaning of the instrument according to the cleaning instructions enclosed in this user manual will ensure
that the instrument continues to operate efficiently and safely in normal everyday use. Cleaning or
decontamination methods, other than those recommended in this guide, should be checked with your instrument
supplier to ensure that the proposed method will not damage the instrument.
1. The outer case work of the Wax Dispenser, including the control panel, may be wiped using small
quantities of mild detergent or polishes applied with a soft cloth.
2. The internal tank can be emptied by locking the delivery tap into the continuous flow position. Any residual
wax at the bottom of the tank can be removed using absorbent tissues and wiped clean.
3. The filter (0.5mm mesh) situated at the bottom of the tank can be cleaned in-situ using a toothbrush or
similar brush, or lifted out once the bolts are removed for more thorough cleaning using solvents. (If removing
the filter it is recommended that protective gloves are worn).
NOTE: DO NOT use scouring pads, de-scaling agents or solvents to clean any parts of this equipment.
Preventative maintenance should include keeping the product clean by protecting it from spillage, contamination
or corrosive environments. If in doubt, please confirm that any intended method of decontamination will not
damage the equipment by contacting Antylia Scientific.
Antylia Scientific recommend that a simple annual inspection be made in order that any malfunction can be identi-
fied and rectified as early as possible. This is to ensure user safety and prolong instrument life span.
Recommended checks to be made:
1. Condition of Power Lead. A visual inspection to ensure the insulation is not damaged and that the correct fuse
is fitted.
2. Functioning of Heater On Lamp. Heater lamp should be on when the instrument is warming up.
3. Condition of the wax dispenser tank and filter (0.5mm mesh). Both tank and filter should be in good condition
with no evidence of corrosion and no damage visible to the filter screen.
4. Dispensing Tap Seal. The dispensing tap should seal correctly with no occurrence of constantly dripping wax
when the tap is not in use.
NOTE: It is normal for a small quantity of molten wax to remain in the tap after it is closed. This residual wax
will drip out, however it will be short lived and will be in very small quantities.
