1. INTRODUCTION.
The MH8516 Paraffin section bath is designed for use as a heated, distilled water floating out
bath for the manipulation and location of paraffin wax sections onto glass slides.
The MH8516 Paraffin bath uses an energy regulator designed to supply power to a silicon
rubber mat heater in controlled timed pulses in order to maintain accurate water
temperatures. A thermal fuse is fitted as in integral part of the heater mat in order to protect
against any over temperature conditions.
With a PTFE black interior and stove enamaled white alluminium exterior your Electrothermal
Paraffin section bath is vertually maintanance free and extremly easy to clean.
This product is supplied with an IEC moulded cord and lead set for ease of operation and the
IEC socket houses protection fuses for both the live and neutral power supply lines. A White
neon indicates the presence of power while the Amber neon indicates when the heater is in
an ‘on’ state.

7.2. With the unit disconnected from the mains electricity supply, half fill the bath tank
with distilled water.
Note: For best operation of this equipment, fill the unit with sterilized distilled water.
The acceptable resistivity range is 50K to 1 Megohms (conductivity 1 to 20 micro
Siemens). The acceptable pH range is 7 to 9.
Caution: Using chlorinated tap water or additives that contain chorine will void the
manufacture warranty. Similary, high purity (deionized) water that does not fall within
a restivity range of 50K to 1 Megohms and pH range of 7 to 9 will void the
manufacture warranty. If you have any questions, please contact Customer support
(see page 15 of this instruction book).
7.3. Plug the unit into the mains electrical supply. Observe the illumination of the White
neon indicating the presence of power.
7.4. Turn the Temperature control voltage regulator knob to the maximum setting. The
objective is to set the shortest warn up time. When the heater cuts in and turns on,
the amber neon will illuminate. This indicates when the heater is on.

Page 11 of 20 M8015 issue 2.1
Note: The Amber neon will switch on and off as the energy regulator cuts in and out.
7.5. When the distilled water has reached the required temperature, reduce the heating
temperature and allow it to stabilise. Add further distilled water if required.
7.6. If an over temperature condition occurs, the bath will turn off. Disconnect from the
mains electricity supply and check there is sufficient distilled water in the bath. When
the unit has cooled down the thermal fuse will reset itself and operation may
commence. If a lack of distilled water isn’t the reason for the over temperature fault
condition, refer to section 10 Customer support.
Take care not to get hot distilled water onto hands /skin
7.7. Regularly check the volume of distilled water present in the unit. Replenish as
required.
