Section 1 Safety Information
Your Thermo Scientific MEGA-PURE 11A water still has been designed
with function, reliability, and safety in mind. It is the user’s responsibility
to install it in conformance with local electrical codes. For safe operation,
pay attention to Notes, Cautions and Warnings throughout the manual.
Warnings
To avoid electrical shock, always:
1. Use a properly grounded electrical outlet of correct voltage and current
handling capacity.
2. Disconnect from the power supply prior to maintenance and servicing.
3. Ensure that the equipment is connected to electrical service according
to local and national standards. Failure to properly connect may create
a fire or shock hazard.
4. Do not mount your Barnstead MEGA-PURE 11A water still directly
over equipment that requires electrical service. Routine maintenance of
this unit may involve water spillage and subsequent electrical shock
hazard if improperly located.
5. For continued protection against possible fire hazard, replace fuses only
with the same type and rating of fuse.
6. Do not connect unit to electrical service until instructed to do so.
To avoid personal injury:
1. Do not use in the presence of flammable or combustible materials; fire
or explosion may result. This device contains components which may
ignite such materials.
2. Glass portions of still become hot when still is operating. To avoid
burns, do not touch hot glass.
3. Wear eye and hand protection when using acid for cleaning, as acid
spattering may occur.

Safety Information
4. Use this device with water feed only. Failure to comply with the above
could result in explosion and personal injury.
5. Ensure all piping connections are tight to avoid leakage of chemicals.
6. Always depressurize chemical lines before disassembly.
7. To avoid lung injury or suffocation, ensure adequate ventilation when
using chemicals for cleaning.
8. Follow carefully the manufacturers' safety instructions on labels of
chemical containers and Material Safety Data Sheets (M.S.D.S.).
9. Refer servicing to qualified personnel.
10. Install front protective cover before operating still.
To ensure safe mounting:
Wall composition and construction, as well as fastener type, must be
considered when mounting this unit. The mounting surface and fasteners
selected must be capable of supporting a minimum of 125 lbs.;
inadequate support and/or fasteners may result in damage to mounting
surface and/or equipment. If you are unsure of mounting surface
composition, condition and construction, or correct fasteners, consult
your building maintenance group or contractor.

Section 2 Introduction
The Thermo Scientific MEGA-PURE 11A water still is a compact, all glass
and PTFE unit designed to provide 11 liters per hour of ultra high purity
distilled water. The product water, as produced, is non-pyrogenic per
U.S.P. XIX and will have a resistivity of 1.0M ohm-cm or higher at the
product outlet using most tap water as feed. This water still can be used as
a discrete unit, with customer supplied pretreated water or in conjunction
with a Thermo Scientific Demineralizer. It can also be connected to the
Thermo Scientific Automatic Collection System for complete automatic
operation.
The MEGA-PURE 11A water still is rated at 240V, 50/60 Hz, 10,000
watts, single phase (Model A440118). It is also available in 208V (Model
A440117). Changing the unit for use on either 240V or 208V operation
requires only replacing the Vycor® immersion heaters with heaters having
the required voltage rating.
The cabinet and glassware are protected against damage from overheating
by two thermal switches.
Choice of a location for your MEGA-PURE 11A water still is primarily a
matter of convenience. This unit may be located on a bench or wall
mounted.
®VYCOR is a registered trademark of Corning, Incorporated.
To operate the MEGA-PURE 11A water still, the customer must provide a
power source of single phase, 50/60 Hz. 60 amp, 208 - 240VAC.
Your water still is supplied with a power cord and plug. A certified
electrician should install a receptacle box within 5' of the still. The correct
receptacle to match the supplied plug is a Hubbel #9460. Figure 2-1 (on
following page) shows proper wiring for this receptacle. As an alternate
method, your electrician may remove the supplied plug and wire the cord
to a 60A-250V breaker box as shown in Figure 2-2.
Note If demineralizer is to be used, a 120V source of power will also be
required. s
